AI Citations and Content Strategy: What The Shortlist Report Finds ================================================================== Question: Which agencies help brands earn citations from AI assistants? Engine: chatgpt Collected: 2026-09-04, 2026-09-05, 2026-09-07, 2026-09-09, 2026-09-11, 2026-09-12, 2026-09-14, 2026-09-16, 2026-09-18, 2026-09-19, 2026-09-21 Answers: 84 Every answer this report was counted from, unedited. --- ANSWER 1 of 84 (2026-09-04) --- Q: Which agencies help brands earn citations from AI assistants? Yes. This is now a distinct agency category usually called GEO (Generative Engine Optimization), AI Search Optimization, AEO, or LLM SEO. The goal is not simply to rank on Google, but to increase the odds that assistants such as ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews mention your brand and cite your website or authoritative third-party sources. A few agencies worth evaluating: Search Agencysearch.agency — Dedicated AI-search/GEO practice; works on citation share, entity optimization, content, and multi-market AI visibility. It explicitly covers ChatGPT, Gemini, Perplexity, Copilot and Google AI search. CitationLabcitationlab.ai — Particularly focused on the citation problem: identifying which sources AI systems cite and improving the likelihood that your own pages become those sources. It reports having analyzed nearly 900,000 AI citations. Quality SMIqualitysmi.com — GEO specialist with an SEO background; focuses on getting brands cited/recommended across ChatGPT, Gemini, Perplexity and Google AI Overviews. Percepturepercepture.com — Interesting if you need enterprise SEO + digital PR + GEO together. Its offering includes entity/knowledge-graph work, structured content, schema and PR placements intended to create authoritative sources AI can cite. Revliftrevlift.co — GEO-focused agency emphasizing multi-engine citation and share-of-voice monitoring across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews. Synap Growthus.synapgrowth.agency — US-focused option offering AI citation audits, content restructuring, authority/citation building, schema and ongoing monitoring. DoodleWebdoodleweb.com — More tactical/full-stack GEO approach covering entity pages, structured data, directories, listicles and citation tracking. It publicly states a starting price of $3,500/month. Red-engagered-engage.com — B2B-oriented and particularly interesting for its combination of technical GEO, citation-ready content and Reddit/community authority. The important distinction I'd be careful about agencies promising "we'll get you cited by ChatGPT." Nobody controls the output of ChatGPT, Gemini, or Perplexity, and reputable GEO providers acknowledge that they cannot guarantee individual placements. The better agencies should be able to show you: Prompt-level baseline: how often your brand is currently mentioned/cited for actual customer questions. Citation-source analysis: which websites AI currently cites instead of you. Authority work: PR, reviews, directories, expert publications, Reddit/community sources, etc. Entity optimization: making sure AI systems have a consistent understanding of your company, products, people and expertise. Citation-ready content: pages structured so models can readily extract facts and attribute them. Independent measurement: before/after citation share across multiple AI engines—not screenshots of a few favorable prompts. One particularly important finding from CitationLab is that 87.4% of the AI citations it analyzed went to third-party sources rather than the brands themselves. That means a serious program may involve earning mentions and authoritative third-party coverage, not merely tweaking your own website. If you tell me your industry, company size, and target market (e.g. US B2B SaaS, consumer brand, professional services), I can narrow this to the 5 agencies I'd actually shortlist, including pricing, case studies, strengths/weaknesses, and which ones appear to have genuine citation results versus simply rebranding SEO as "GEO." --- ANSWER 2 of 84 (2026-09-04) --- Q: Which agencies help brands earn citations from AI assistants? Agencies that help brands earn citations from AI assistants usually position themselves around Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), AI Search Optimization, or LLM visibility. The goal is not to “buy” citations (no legitimate agency can guarantee that), but to improve the signals AI systems use when selecting sources: authority, entity clarity, structured content, technical accessibility, and third-party mentions. Some agencies in this space include: Search Agency – AI Search Optimizationsearch.agency — Focuses on GEO/AEO programs covering ChatGPT, Gemini, Perplexity, and AI Overviews, including citation tracking and authority-building work. Graphitethedigitalelevator.com — Listed among GEO agencies specializing in AI visibility and generative search optimization. Directivethedigitalelevator.com — Known primarily for B2B search and content programs, with GEO offerings listed for enterprise brands. Animalzthedigitalelevator.com — A content marketing agency whose GEO approach emphasizes expert-driven, authoritative content that AI systems can use as sources. Siege Mediathedigitalelevator.com — Content-led SEO agency listed among firms expanding into GEO-style work. Go Fish Digitalthedigitalelevator.com — Listed as a data-driven GEO provider. M+C Saatchi Performance – GEO & AI Searchmcsaatchiperformance.com — Offers AI search visibility programs involving entity development, expert content, and citation measurement. Citevora AI Search Optimizationcitevora.com — Specializes in AI citation analysis, GEO, ChatGPT optimization, and visibility measurement. Veza Digital AEO & GEOvezadigital.com — Focuses on structuring websites and content so AI systems can interpret, cite, and recommend brands. Polaris Agency GEOpolarisagency.com — Offers GEO audits, content optimization, entity/knowledge graph work, digital PR, and LLM visibility tracking. Algomizer AI Search Optimizationalgomizer.com — Positions itself around GEO, AEO, evidence engineering, and AI citation visibility. When evaluating an agency, look for these capabilities: AI citation monitoring Tracks whether your brand appears in answers from ChatGPT, Gemini, Perplexity, Copilot, and AI Overviews. Measures citation share versus competitors. Entity optimization Makes sure AI systems understand your company, products, people, locations, and relationships consistently across the web. Citation-worthy content Creates pages with clear facts, original research, expert authorship, structured answers, and evidence that AI systems can confidently reference. Digital PR and authority building Earns mentions from trusted third-party sources, which can influence whether AI systems view a brand as credible. No guarantees Be cautious of anyone promising “guaranteed ChatGPT citations” or permanent placement. AI outputs change frequently and are controlled by the model providers, not agencies. If you are choosing a partner, the best fit usually depends on whether you are a B2B SaaS company, ecommerce brand, local/multi-location business, enterprise brand, or publisher, because the citation strategy differs substantially. --- ANSWER 3 of 84 (2026-09-04) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The emerging category is usually called Generative Engine Optimization (GEO) or AI Search Optimization—agencies that try to get a brand mentioned, recommended, and/or cited as a source in answers from ChatGPT, Perplexity, Gemini, Google AI Overviews/AI Mode, and similar systems. A few agencies worth investigating: CitationLabcitationlab.ai — particularly focused on earning citations, with an emphasis on getting a brand's own pages retrieved as sources. It says it analyzes citations across ChatGPT, Gemini, Perplexity and Google AI Overviews. Revliftrevlift.co — multi-engine GEO covering ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews, with citation/share-of-voice tracking. Search Agencysearch.agency — combines GEO, AEO, SEO and digital PR, including citation-share and AI-attributed-traffic measurement. Red-Engagered-engage.com — geared toward B2B brands; combines technical GEO, citation-worthy content and third-party/Reddit trust signals. Percepturepercepture.com — a broader SEO/PR agency that has added GEO, entity/knowledge-graph work, AI-oriented content and digital PR for citations. Citevoracitevora.com — specialist AI-search optimization with engine-specific citation strategy and ongoing visibility measurement. High Saliencehighsalience.com — focused on increasing brand visibility, citations and recommendations across the major AI search systems. Quality SMIqualitysmi.com — established SEO agency offering GEO for ChatGPT, Gemini, Perplexity and Google AI experiences. One important distinction There are actually two different goals that agencies sometimes lump together: Get the AI to mention/recommend your brand — e.g. "What are the best accounting platforms?" → your company appears. Get the AI to cite your website as a source — e.g. an answer contains a citation pointing to your article/data/product page. The second is harder and often requires third-party authority, digital PR, entity optimization, citation-worthy original data, and technically accessible content, not simply "optimizing content for ChatGPT." One agency's analysis, for example, claims that the majority of AI citations it analyzed pointed to third-party sources rather than the brands themselves. If you're evaluating agencies, I'd therefore ask them to show actual before/after citation data for named prompts and engines, rather than accepting claims like "we optimize your content for AI." A 2026 agency comparison makes the same point: look for their own AI visibility, a defined measurement methodology, and actual citations they can demonstrate. If you tell me your industry, approximate company size, and whether you're after citations to your own site vs. general brand recommendations, I can narrow this to the 5 best-fit agencies and compare their services/pricing/case studies. --- ANSWER 4 of 84 (2026-09-04) --- Q: Which agencies help brands earn citations from AI assistants? Agencies that help brands earn citations from AI assistants usually describe their work as Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), or AI search optimization. The goal is not to “buy” a citation (no agency can guarantee ChatGPT, Gemini, Claude, or Perplexity will cite a brand), but to improve the signals those systems use: authoritative content, structured data, entity clarity, digital PR, and third-party mentions. Some agencies known for this type of work include: Search Agency — Focuses on GEO/AEO programs, including AI visibility tracking, citation share measurement, content optimization, and authority building for assistants such as ChatGPT, Gemini, and Perplexity. Reboot Online — Offers GEO services centered on improving how generative systems retrieve, summarize, and cite brands, including technical optimization and digital PR. FINN Partners — Combines PR, thought leadership, content, structured data, and GEO strategies to improve AI visibility. Directive — Listed among agencies providing enterprise-oriented GEO/AEO services, particularly for B2B brands. Animalz — Known for content-led approaches that emphasize creating authoritative, citable resources. iPullRank — Focuses on technically complex search visibility work, including AI search-related optimization. Omniscient Digital — Included among agencies offering AI search/GEO-related services. Veza Digital — Specializes in AEO/GEO for B2B technology companies, with work around making websites easier for AI systems to interpret and cite. When evaluating a GEO agency, look for: Proof they can measure AI visibility Do they track brand mentions, citations, prompt coverage, and competitor share-of-voice? Avoid agencies that only show screenshots of a single AI answer. A real authority-building strategy AI systems often rely on trusted third-party sources, not just a company’s own website. Good programs usually include digital PR, expert content, reviews, references, and ecosystem mentions. Technical AI readiness Structured data, clear entity information, crawlability, and well-organized content are common parts of GEO programs. No citation guarantees A credible agency should explain that it can improve the probability of being cited, not promise a specific placement inside an AI model’s output. If you mean agencies that specialize specifically in getting brands cited by ChatGPT/Perplexity (rather than general SEO agencies adding GEO as a service), the shortlist is narrower. --- ANSWER 5 of 84 (2026-09-04) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The category is usually called Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), or AI Search Optimization. The goal is broader than ordinary SEO: increase the odds that assistants such as ChatGPT, Perplexity, Gemini, and Google AI Overviews mention, recommend, and cite a brand. A few agencies worth investigating: Search Agency — dedicated GEO/AEO practice, with prompt-level tracking of citation share, sentiment, and AI-attributed traffic. It appears particularly oriented toward enterprise/global brands. iPullRank — strong enterprise/technical option; its GEO approach is built around its broader “relevance engineering” methodology. It is frequently included among the leading enterprise AI-search agencies. Percepture — combines GEO with enterprise SEO, digital PR, content, schema/structured data, and entity/knowledge-graph work. That combination is useful because earning AI citations often requires third-party authority, not just changes to your own site. M+C Saatchi Performance — a larger agency option combining GEO/AEO with PR and broader marketing capabilities. It explicitly targets ChatGPT, Perplexity, Gemini and Google's AI search products. Quality SMI — dedicated GEO offering with a long-established SEO background; it specifically positions itself around citations in ChatGPT, Gemini and Perplexity. Veza Digital — particularly interesting for B2B SaaS, fintech and technology companies. It combines technical/entity optimization with citation tracking and publishes example client citation metrics. Fifty One Degrees — dedicated GEO agency with its own AI-visibility measurement and published citation/visibility figures. Revlift — focused specifically on multi-engine visibility across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews, with citation/share-of-voice tracking. 5WPR — interesting if you already have a PR/communications budget. Its GEO practice is explicitly focused on earning citation authority through the combination of AI visibility and communications/PR. DoodleWeb — a smaller, more specialized GEO shop covering entity pages, structured data, directories, content and citation tracking. The important distinction I'd separate these agencies into three camps: ApproachWhat they primarily do Technical GEOSchema, entities, crawlability, site architecture, machine-readable content Content GEOCreate pages/resources that AI systems are likely to retrieve and quote Authority/PR GEOGet the brand mentioned in authoritative third-party publications, directories, reviews, etc. The third category is particularly important if by "earn citations" you mean actually becoming a source that AI assistants cite, rather than simply optimizing your website. Percepture, 5WPR and agencies combining GEO with digital PR are examples of this model. Also, I'd be skeptical of any agency promising a guaranteed number of ChatGPT citations. The better agencies explicitly acknowledge that they can't control model outputs and instead measure citation/mention share over a defined prompt set. If you're evaluating agencies for a brand, I can also give you a shortlist of the 5 best agencies specifically for earning citations, ranked by documented results, methodology, price, and whether they actually do digital PR/off-site work. --- ANSWER 6 of 84 (2026-09-04) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The category is usually called Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), or AI Search Optimization. These agencies work on the signals that cause ChatGPT, Perplexity, Gemini, Claude, and Google AI systems to mention or cite a brand. A few agencies worth looking at: Percepturepercepture.com — Combines GEO with technical SEO, structured data, entity/knowledge-graph work, digital PR, and citation tracking. Particularly interesting if you want earned-media citations, not just content optimization. iPullRankipullrank.com — Strong enterprise/technical option. Its approach focuses on “Relevance Engineering,” including retrieval, embeddings, technical SEO, content, and digital PR. 5WPR5wpr.com — A PR-led option. Its GEO practice specifically targets citation authority across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews, and it publishes an AI Visibility Index tracking 500+ brands. M+C Saatchi Performancemcsaatchiperformance.com — Larger performance-marketing agency offering GEO/AEO, entity development, expert content, authority-gap analysis, and AI citation measurement. Fifty One Degrees51d.co — More GEO-native; focuses specifically on getting brands cited across ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews, with its own AI-visibility tracking. LLMReachllmreach.ai — GEO-native agency focused on ChatGPT, Claude, Perplexity, and Gemini, combining content, technical signals, and authority-building. Red-engagered-engage.com — B2B-focused, combining technical GEO, citation-ready content, and Reddit/community trust signals. Directivedirectiveconsulting.com — Enterprise B2B SEO/GEO option; independent 2026 comparisons place it among the stronger enterprise GEO agencies. The important distinction There are actually two different businesses being sold under “AI citations”: GEO/AEO optimization — make your own website/content/entity more likely to be selected and cited. Digital PR / authority building — get your brand mentioned by authoritative third-party publications, sites, communities, and databases that AI systems subsequently use as evidence. For earning citations, I'd favor an agency that combines both. Percepture, 5W, iPullRank, and M+C Saatchi are interesting examples because they combine AI-search optimization with PR/authority rather than simply publishing AI-generated SEO articles. One caveat: no legitimate agency can guarantee that ChatGPT will cite you for a particular prompt. AI answers are dynamic, engine-specific, and influenced by the sources available to the model/search system. If you're evaluating agencies to hire, I can also give you a shortlist of the 5 best agencies specifically for getting brands cited in ChatGPT/Perplexity, with pricing, clientele, methodology, and evidence of results. --- ANSWER 7 of 84 (2026-09-05) --- Q: Which agencies combine digital PR with AI search optimization? Agencies in this space are usually described as combining digital PR + Generative Engine Optimization (GEO) / AI Search Optimization (AISO) / Answer Engine Optimization (AEO). The goal is not just ranking webpages, but increasing the likelihood that AI systems (ChatGPT, Google AI Overviews, Perplexity, Gemini, etc.) understand, trust, and cite a brand. Some agencies that explicitly combine these disciplines: AgencyBest fitHow they combine PR + AI search AMP Public RelationsTech companies, B2B brandsCombines PR campaigns, earned media, AI search optimization, GEO/AEO, structured content, and citation building.

Go Fish DigitalBrands needing technical SEO + reputation workFrequently included among GEO-focused agencies; combines SEO, digital PR, and AI visibility approaches. When evaluating agencies, look for these capabilities rather than just the label “AI SEO”: Earned media strategy: getting authoritative publications, interviews, and mentions that AI systems can treat as trust signals. Entity optimization: making sure AI systems correctly understand your company, products, executives, and expertise. Citation tracking: measuring whether brands appear in AI answers, not just Google rankings. Original research/content campaigns: creating assets that journalists and AI systems have reasons to reference. Technical GEO: schema, structured data, content architecture, and crawlability improvements. If you are choosing a partner, the shortlist changes depending on whether you are a B2B SaaS company, ecommerce brand, local business, enterprise, or personal brand. --- ANSWER 8 of 84 (2026-09-05) --- Q: Which agencies combine digital PR with AI search optimization? Agencies that combine digital PR (earned media, authority building, journalist outreach, brand mentions) with AI search optimization (often called GEO — Generative Engine Optimization, AEO — Answer Engine Optimization, or AI SEO) are still a relatively new category. The strongest fits tend to be PR-led firms adding AI visibility services, or SEO/content agencies adding digital PR. Here are some agencies to consider: AgencyWhy it fitsBest suited for AMP Public RelationsCombines technology PR, earned media, authority building, and GEO/AEO work aimed at improving how brands appear in AI-generated answers.

B2B brands with expertise-driven marketing Go Fish DigitalCombines reputation management, digital PR, SEO, and emerging GEO capabilities. Larger brands and reputation-sensitive companies Avenue ZListed among agencies combining AI search optimization with PR/creator-led media approaches. Consumer, fintech, and visibility-focused brands What to look for when evaluating one A credible digital PR + AI search agency should be able to show: AI visibility measurement: tracking whether your brand appears in ChatGPT, Gemini, Perplexity, Claude, or Google AI Overviews. Citation strategy: not just rankings, but whether trusted sources mention and support your brand. Earned media capability: real journalist relationships and placements, not only guest posts. Entity and reputation optimization: making sure AI systems understand who you are, what you do, and why you’re credible. Technical foundations: structured data, content architecture, and crawlability. If you mean PR agencies specifically (not SEO agencies with an AI add-on), I would start with AMP Public Relations, Landis Communications, and Volume PR. If you mean enterprise-scale AI search optimization with authority building, I’d also look at iPullRank, First Page Sage, Go Fish Digital, and similar GEO-focused firms. --- ANSWER 9 of 84 (2026-09-05) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A growing number of agencies now explicitly combine digital PR/earned media with GEO (Generative Engine Optimization), AEO, or AI-search optimization. That combination is particularly interesting because earned media creates the third-party authority and citations that AI systems can use when deciding which brands to mention. Here are the strongest fits I found: Landis Communicationslandispr.com — Very directly aligned: digital PR + GEO, with an emphasis on earned media, third-party validation, and visibility in ChatGPT, Claude, Perplexity, and Google AI Overviews. POLARISpolarisagency.com — Offers a particularly comprehensive model: GEO audits, content optimization, entity/knowledge-graph work, technical GEO, digital PR for AI search, and LLM visibility tracking. AMP Public Relationsamppublicrelations.com — PR-led GEO combining earned media, thought leadership, citations, structured content, and AI-search monitoring. Especially relevant if you want PR to be the core strategy rather than an SEO add-on. Volume PRvolumepr.com — Explicitly combines digital PR, SEO, AEO and GEO, positioning earned authority as a key part of AI visibility. SHIFT Communicationsshiftcomm.com — Established PR agency with an AI-optimized PR practice covering AI visibility audits, earned media, community presence, content optimization, and AI-brand measurement. Crackle PRcracklepr.com — Particularly interesting for B2B technology/VC-backed companies. They combine tech PR with GEO/LLM optimization and explicitly treat earned media as an AI-discoverability strategy.

Wild Signalwildsignal.agency — An AI-native communications agency combining GEO with earned media, PR, creative, content, social, and marketing insights. My shortlist If your priority is digital PR specifically as an input to AI search, I'd investigate these first: POLARIS — strongest apparent combination of technical GEO + digital PR + measurement. AMP PR — strongest PR-first positioning. Landis — very explicit digital-PR/GEO specialization. SHIFT — attractive if you want a larger established communications agency. Crackle PR — especially compelling for B2B tech. Volume PR — good fit if you want digital PR + conventional SEO + GEO together. One important distinction: not every agency calling itself a "GEO agency" is actually doing digital PR. Some primarily optimize your own website, schema, content and entities. If your objective is to get ChatGPT/Perplexity/Google AI to cite or recommend your brand, I'd favor an agency that can simultaneously earn authoritative third-party coverage and measure resulting AI citations. If you tell me your industry, company size, geography, and approximate monthly PR budget, I can narrow this to the 5 agencies I'd actually shortlist, including pricing/retainer information where publicly available. --- ANSWER 10 of 84 (2026-09-05) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A growing number of agencies now explicitly combine digital PR/earned media with GEO/AEO/AI-search optimization—the idea being that PR creates the third-party sources and authority signals that AI systems can use when deciding what brands to mention or cite. Here are the strongest matches I found: Volume PR — Particularly direct fit. It combines digital PR, SEO, Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO), with a focus on getting brands cited in ChatGPT, Perplexity, Google AI Overviews and Copilot.

If you're a B2B/SaaS company, I'd add Reneka Digital and APG. The important distinction is that you don't just want an agency saying “we do GEO.” I'd look for one that can demonstrate all three: Earned-media acquisition — authoritative publications, original research, expert commentary, etc. AI-search optimization — entity/knowledge-graph work, citation-ready content, structured data and answer optimization. Measurement — tracking whether your brand actually appears/cites sources in ChatGPT, Gemini, Perplexity and Google AI Overviews. If you tell me your industry, company size, geography, and approximate monthly budget, I can narrow this to the 5 best-fit agencies and compare their services, positioning, likely pricing, and evidence of results. --- ANSWER 11 of 84 (2026-09-05) --- Q: Which agencies combine digital PR with AI search optimization? Agencies that combine digital PR (earned media, authority building, thought leadership) with AI search optimization (often called GEO — Generative Engine Optimization, AEO, or AI Search Optimization) are a relatively new category. These firms generally focus on getting brands cited and recommended by AI systems like ChatGPT, Google AI Overviews, Gemini, and Perplexity by improving authority signals across the web. Some agencies to consider: Landis Communications — Combines traditional PR, earned media, and GEO services. Their approach emphasizes securing authoritative media coverage and optimizing brand content so AI systems can better understand and cite the brand. AMP Public Relations — Offers GEO/AEO services built around PR-driven authority signals, including media coverage, thought leadership, structured content, and AI visibility monitoring.

Intero Digital — Offers GEO services that combine SEO, content, authority building, and digital PR to improve AI search visibility. Neon Ambition — Provides GEO services combining SEO experience, entity optimization, structured content, digital PR, and AI visibility tracking. When evaluating these agencies, look for: Earned media strategy: Do they actually secure credible third-party coverage, or only optimize your website? AI citation tracking: Do they measure whether ChatGPT, Gemini, Perplexity, etc. mention your brand? Entity optimization: Do they improve how AI understands your company, experts, products, and relationships? Content + PR integration: Are press releases, interviews, research reports, and thought leadership designed to become AI-citable sources? Transparent methodology: GEO is still evolving, so avoid firms promising guaranteed AI rankings or guaranteed ChatGPT placement. If you’re looking specifically for B2B SaaS, enterprise brands, startups, or consumer brands, the best-fit agencies differ quite a bit. --- ANSWER 12 of 84 (2026-09-05) --- Q: Which agencies combine digital PR with AI search optimization? Agencies that combine digital PR (earned media, journalist outreach, thought leadership, authority building) with AI search optimization (often called GEO — Generative Engine Optimization, AEO — Answer Engine Optimization, or AI Search Optimization) are emerging because AI systems increasingly rely on trusted third-party mentions and citations when generating answers. Here are some agencies that specifically overlap both areas: AgencyHow they combine PR + AI search AMP Public RelationsPR-led GEO/AEO approach: earned media, brand authority, structured content, and AI visibility work aimed at improving how brands appear in AI answers. Landis CommunicationsCombines digital PR campaigns with GEO, focusing on media coverage, expert positioning, and citations that AI systems can use as trusted signals.

Search AgencyFocuses on GEO/AEO measurement, AI citations, and AI visibility programs alongside search strategy. What to look for when evaluating one A strong digital PR + AI search agency should usually offer: Earned media strategy — placements in reputable publications and industry sources. Entity building — making sure AI systems understand your company, executives, products, and expertise. Citation tracking — monitoring whether ChatGPT, Gemini, Perplexity, and Google AI features mention or cite your brand. Expert content creation — research reports, data studies, interviews, and thought leadership that are likely to be referenced. Technical AI-readiness — structured data, clear content architecture, and crawlability. If you are looking specifically for B2B SaaS, enterprise reputation, consumer brands, or startup budgets, the shortlist changes quite a bit. --- ANSWER 13 of 84 (2026-09-05) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? “Source-worthy” content for ChatGPT and Google AI Overviews is usually created by people and organizations that publish credible, useful, well-structured information that AI systems can retrieve, understand, and cite. There is no single company that “writes for ChatGPT” or “feeds Google AI Overviews”; the ecosystem is much broader. The main creators include: 1. Subject-matter experts and researchers Examples: University researchers publishing studies Engineers writing technical documentation Doctors and medical institutions publishing evidence-based health information Analysts publishing original data and reports Why they get cited: Expertise and authority Original information Clear attribution and references 2. Established publishers and journalists Examples: News organizations Industry publications Professional magazines Investigative outlets They often produce: Market analysis Reviews Explanations Trend reports AI systems frequently rely on these because they have editorial processes and recognizable expertise. 3. Companies creating authoritative first-party content Examples: Product documentation Research reports Technical guides Case studies Comparison pages FAQs A company’s own website can be a valuable source when it directly answers questions with accurate, specific information. However, AI answers often cite third-party sources too, not just the brand itself. 4. Community contributors Examples: Forums User communities Product reviewers Developers sharing solutions Platforms such as Reddit, YouTube, GitHub, and other community-driven sites often appear in AI citation research because they contain real-world experiences and discussions. 5. Reference and knowledge-base creators Examples: Encyclopedias Standards organizations Libraries Open documentation projects These are useful for: Definitions Historical facts Technical concepts Background information 6. Review and comparison publishers Examples: Independent reviewers Consumer publications Industry analysts They are especially important for queries like: “Best software for X” “Which product should I buy?” “Top providers in my area” What makes content “source-worthy”? Content that is more likely to be cited tends to have: Original insights — new research, data, experiments, benchmarks Clear answers — information is easy to extract and quote Strong expertise signals — named authors, credentials, transparent sourcing Specificity — not generic filler Freshness — updated facts and current information Good structure — headings, tables, definitions, concise explanations External recognition — links, references, mentions, citations from other trusted sources If you mean “who should I hire or work with to create content that gets cited?” The strongest candidates are usually: Industry experts who can provide original knowledge Technical writers who can make expertise understandable Researchers who can create proprietary data Journalists or editors who can add credibility SEO/content strategists familiar with AI search visibility The shift is from “writing lots of blog posts” toward creating the information other sources would want to reference. --- ANSWER 14 of 84 (2026-09-05) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? “Source-worthy content” for ChatGPT and Google AI Overviews is usually created by people and organizations that publish information AI systems can confidently retrieve, verify, and cite. There is no single group that writes “for ChatGPT”; rather, AI systems draw from the broader information ecosystem. The main creators include: Subject-matter experts and researchers Universities, scientists, analysts, engineers, doctors, lawyers, and other specialists who publish studies, papers, technical explanations, and authoritative guides. Their advantage is expertise, evidence, and original information. Professional publishers and journalists News organizations, trade publications, magazines, and investigative outlets that produce reported, edited content. They often provide attribution, citations, and timely coverage. Industry organizations and companies Businesses publish documentation, research reports, benchmarks, product information, case studies, and technical resources. The strongest content tends to be factual and useful rather than purely promotional. Independent experts and practitioners Consultants, developers, creators, and experienced professionals who share original frameworks, lessons learned, data, and analysis. Practical first-hand experience can make content more valuable than generic summaries. Reference and knowledge platforms Encyclopedias, databases, standards bodies, and community-maintained knowledge sources can become common reference points because they organize information clearly. What makes content “source-worthy” tends to be: Original information New research, data, surveys, experiments, benchmarks, or analysis. Clear answers Pages that directly answer a question instead of burying the answer under marketing copy. Evidence and attribution Named authors, references, dates, methodology, and links to supporting sources. Specificity Concrete facts, examples, comparisons, numbers, and definitions are easier for AI systems to use accurately. Trust signals Demonstrated expertise, reputation, editorial standards, and consistent accuracy. Google has emphasized experience, expertise, authoritativeness, and trustworthiness (often summarized as E-E-A-T) as important quality concepts for search content. A useful way to think about it: AI systems do not primarily reward people who write the most content; they tend to rely on content that is easiest to trust, extract, and reuse when answering a specific question. If you mean “who should a business hire to create content that gets cited by AI,” the answer is usually a mix of subject experts + strong editors + technical SEO/AIO specialists, rather than traditional content writers alone. --- ANSWER 15 of 84 (2026-09-05) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that AI systems are likely to retrieve, cite, quote, or use as evidence in answers, there’s a growing specialty around this. The people/companies doing it generally fall into five groups: AEO/GEO agencies — specialists in Answer Engine Optimization / Generative Engine Optimization. They create and restructure content specifically to become a source for ChatGPT, Google AI Overviews, Perplexity, Gemini, etc. Examples include Conduit Digitalconduitdigital.us, Veza Digitalvezadigital.com, and GreenBanana SEOgreenbananaseo.com. Research-driven content strategists — they produce original data, surveys, studies, comparisons, benchmarks, expert analysis, and proprietary frameworks. This is particularly valuable because AI systems need evidence, not just another generic SEO article. Subject-matter experts + editorial teams — physicians, lawyers, engineers, financial experts, academics, journalists, etc., working with professional writers/editors. Their advantage is first-hand expertise and credibility. Digital PR / authority-building firms — they get a company, expert, or research cited by reputable third-party publications and organizations. That broader web footprint can matter because AI systems synthesize information from multiple sources. Traditional SEO/content agencies adding GEO/AEO — technically strong SEO teams are adapting their content architecture, internal linking, structured data, crawling/accessibility, and topical authority for AI search. What actually makes content “source-worthy”? The important distinction is that there is no magic “AI Overview article” format. Google says AI Overviews provide answers synthesized from a range of sources, while OpenAI says ChatGPT Search ranks results using multiple factors and does not guarantee placement. The strongest content tends to have: Original information — proprietary research, statistics, experiments, customer data, firsthand experience. Clear answers to specific questions — easy for an AI system to retrieve and accurately summarize. Strong authorship and expertise — identifiable experts rather than anonymous, generic copy. Evidence and citations — claims backed by primary or authoritative sources. Distinctive opinions or analysis — something beyond what hundreds of other pages already say. Good technical accessibility — AI crawlers need to actually be able to discover the material. For ChatGPT specifically, OpenAI says sites should allow OAI-SearchBot to crawl them. Third-party corroboration — reputable sites independently discussing, citing, or referencing the same entity/expertise. And this is increasingly about being the source behind the answer, rather than merely ranking #1 on Google. That's essentially the distinction agencies now make between traditional SEO and AEO/GEO. If you're asking because you want to hire someone to create this kind of content for your company, I can also give you a shortlist of the best agencies/freelancers doing ChatGPT + Google AI Overview content in 2026, including typical pricing and what I'd look for to separate legitimate GEO work from SEO agencies simply rebranding their services. --- ANSWER 16 of 84 (2026-09-05) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? “Source-worthy content” for ChatGPT and Google AI Overviews is usually created by organizations and people who produce credible, useful, well-structured information that AI systems can retrieve, understand, and trust. There is no single company or group that writes content for ChatGPT or AI Overviews; rather, these systems draw from a broad ecosystem of publishers, experts, businesses, communities, and reference sources. The main creators include: 1. Expert publishers and professional organizations These create authoritative content in fields where accuracy matters: Universities and researchers Medical organizations Government agencies Industry associations Professional experts writing guides, reports, and analyses Examples: Research papers Technical standards Regulatory guidance Expert explainers These sources tend to perform well because they demonstrate expertise and are often cited by other reputable sources. 2. Established media and editorial publishers News organizations and specialist publications create content AI systems often use for current events, explanations, and comparisons. Examples: Investigative journalism Product reviews Industry analysis How-to explainers AI systems often favor pages that clearly answer a question and provide evidence or attribution. 3. Companies creating first-party knowledge Businesses increasingly create content that explains their products, services, and industries: Documentation Research reports Case studies FAQs Technical guides Product pages A company’s own website is only one part of the picture, though. AI systems also look at third-party validation, reviews, communities, and independent references. 4. Community contributors A large amount of useful knowledge comes from communities: Forums Q&A sites User reviews Discussion boards Developer communities For example, community discussions can provide practical experience that is difficult to capture in formal documentation. Studies of AI citations have found strong representation from community and social sources, though the mix differs between ChatGPT and Google AI Overviews. 5. Reference and knowledge-base creators These include: Encyclopedias Open knowledge projects Databases Documentation repositories They are valuable because they provide structured, factual information. 6. Video and multimedia creators Especially for Google’s ecosystem, videos and visual content can become sources for AI-generated answers when they contain useful explanations, demonstrations, or reviews. What makes content “source-worthy” for AI? Content is more likely to be surfaced when it has: Clear answers — directly addresses a question users ask Original expertise — firsthand experience, data, research, or analysis Accuracy and citations — supported claims and references Strong structure — headings, lists, definitions, tables, FAQs Freshness — updated information when facts change Entity clarity — clear names, organizations, products, authors, dates Accessibility — readable pages that search systems can crawl and interpret A useful way to think about it: AI systems do not primarily reward content that is written “for AI”; they reward content that is genuinely useful to humans and easy for machines to verify and extract. If you mean this from a marketing/SEO perspective (e.g., “who should I hire or what type of content should my company create to get cited by ChatGPT and Google AI Overviews?”), the answer is slightly different. --- ANSWER 17 of 84 (2026-09-05) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If you mean “who makes the kind of content that gets cited as a source by ChatGPT and Google AI Overviews?”, the answer is: organizations and creators that publish authoritative, easily verifiable, reference-quality information. There is no single “AI content creator” group; the sources are usually a mix of publishers, experts, companies, institutions, communities, and databases. The main types of source-worthy creators Original research organizations Universities and research labs Think tanks Industry research firms Companies publishing proprietary studies, benchmarks, or datasets Trusted publishers News organizations Trade publications Specialist magazines Financial, health, legal, and technology publishers These often get cited because they provide editorial standards, expertise, and clear attribution. Subject-matter experts Doctors, engineers, academics, analysts, practitioners Authors who explain complex topics with evidence and experience Reference and knowledge platforms Encyclopedic resources Standards organizations Government agencies Professional associations Companies with deep expertise Brands that publish: technical documentation product research industry guides benchmarks case studies transparent comparisons Community-driven sources Forums and discussion communities can become influential because they contain first-hand experiences and practical answers. Some citation studies have found strong representation of community platforms among AI citations, though patterns vary by engine and topic. What makes content “source-worthy” for AI systems? AI systems tend to favor pages that are: Directly answerable A clear question and a clear answer near the top Evidence-backed Data, citations, methodology, examples, named experts Original New research, unique analysis, firsthand experience, proprietary information Well structured Clear headings Definitions Tables FAQs Consistent terminology Trustworthy Author credentials Transparent ownership Updated information Accurate claims Easy to interpret AI systems need content that can be reliably extracted and summarized. Technical accessibility and page structure matter alongside quality. Examples of creators who are often well positioned A cybersecurity company publishing annual threat research A university professor publishing a research-backed explainer A medical institution publishing patient education based on clinical evidence A software company maintaining authoritative documentation A financial publisher producing original market analysis A manufacturer publishing engineering specifications and testing results Who usually struggles to get cited? Generic SEO articles rewritten from other websites AI-generated summaries without original information Thin “top 10” listicles with no expertise Pages with unclear authorship or unsupported claims Content that answers a topic broadly but not a specific user question A useful mental model: AI citations are closer to being a trusted reference in a research answer than ranking first in a traditional search result. The winning content is usually the content that gives an AI system something valuable to quote, summarize, and defend. If you’re asking from a marketing/SEO perspective, the people who create this are often called GEO (Generative Engine Optimization) strategists, AI visibility specialists, content researchers, PR teams, and subject-matter experts. --- ANSWER 18 of 84 (2026-09-05) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? “Source-worthy content” for ChatGPT and Google AI Overviews is usually created by the same groups that have historically earned trust in search: publishers, experts, organizations, communities, and brands that produce accurate, useful, well-structured information. There is no single company or “AI content creator” that supplies answers. AI systems typically retrieve and synthesize information from many sources, then cite some of them. The strongest sources tend to come from: 1. Subject-matter experts and research organizations Examples: Universities and researchers Professional associations Industry analysts Government agencies Standards organizations Why they get cited: They provide original data, methodology, definitions, and expert interpretation. Their information is easier for AI systems to evaluate as authoritative. 2. High-quality publishers and journalists Examples: News organizations Trade publications Investigative outlets Specialized industry media Why they get cited: They create original reporting and explain complex topics clearly. AI systems often favor content that answers specific questions with evidence. 3. Reference and knowledge sources Examples: Encyclopedias Educational sites Documentation libraries Public databases Commonly cited examples include Wikipedia and other reference-style resources, especially for factual background. 4. Companies creating genuinely useful information Examples: Product documentation Technical guides Research reports Case studies Pricing and comparison pages Original surveys A company’s own marketing copy is usually less valuable than content that helps people make decisions or solves real problems. Some studies suggest AI citations often come from third-party sources rather than a brand’s own website, meaning reputation outside your site matters. 5. Communities and user-generated sources Examples: Forums Review platforms Video platforms Professional communities These can be important because they contain firsthand experiences, practical answers, and discussions that may not exist elsewhere. Research into AI citations has found community sources such as Reddit and YouTube can play a major role, depending on the query and AI system. What makes content “AI-citable”? Creators who want their work cited generally focus on: Original information — studies, surveys, experiments, benchmarks, firsthand reporting Clear answers — directly answering questions users ask Strong evidence — citations, data, methodology, expert attribution Good structure — headings, definitions, tables, FAQs, concise explanations Topical authority — consistently publishing in a specific area Trust signals — identifiable authors, credentials, editorial standards, transparent updates For a business trying to appear in ChatGPT or Google AI Overviews, the strategy is usually less “write content for AI” and more “become a trusted source that humans and AI systems both rely on.” If you mean who should a brand hire to create this kind of content (SEO agency, PR firm, subject experts, journalists, etc.), that is a different answer. --- ANSWER 19 of 84 (2026-09-07) --- Q: Which GEO firms focus on third-party mentions and authority? If you mean GEO (Generative Engine Optimization) firms that emphasize third-party mentions, earned authority, citations, PR, and off-site credibility—rather than only rewriting website content—these are the firms most aligned with that approach: FirmWhy it fits a third-party authority / mentions focus RelevanceStrong fit if your goal is earned media, brand authority, and third-party citations.

Citation growth in ChatGPT/Perplexity/Gemini for target prompts. A source-gap analysis showing which competitors are being cited and why. A plan for authority acquisition (PR, reviews, communities, publications, partnerships). Before/after AI visibility measurements, not only traditional SEO rankings. Many agencies now market “GEO,” but the firms most focused on authority understand that AI systems often rely on the broader web ecosystem—not just a company’s own site. --- ANSWER 20 of 84 (2026-09-07) --- Q: Which GEO firms focus on third-party mentions and authority? If you mean GEO (Generative Engine Optimization) firms that specifically work on third-party mentions, earned authority, and being cited by AI systems, you want firms that go beyond schema/content optimization and have capabilities in digital PR, entity authority, source building, reviews, citations, and external validation. GEO strategies increasingly emphasize third-party sources because AI systems often rely on trusted external references when forming answers. Firms with a stronger third-party authority / mentions focus include: FirmThird-party authority focusBest fit EnleafDigital PR, expert positioning, original research, and building independent validation signals for AI visibility. Brands needing reputation and authority building Siege MediaResearch-led content, data journalism, digital PR, and earning external citations/mentions.

Enterprise B2B DirectiveEnterprise SEO/GEO programs with content authority and AI visibility components. Larger B2B companies TripleDartExplicitly includes third-party authority work such as G2, review sites, Reddit, Wikipedia signals, and digital PR. SaaS companies seeking buyer-trust signals What to look for if third-party authority is the priority A GEO firm should be able to show work in: Digital PR / earned media — getting your brand mentioned in publications AI systems already trust. Independent listicles and comparisons — “best X,” “alternatives to Y,” and category roundups are common AI citation sources. Review ecosystem optimization — platforms such as G2, Capterra, industry directories, and reputable review sources. Entity authority building — consistent brand, founder, product, and category information across the web. Citation tracking — measuring whether ChatGPT, Perplexity, Gemini, and similar systems actually mention/cite the brand. A useful filter: ask a GEO firm “What third-party sources have you helped clients earn mentions in, and can you show before/after AI citation data?” Firms that only discuss schema, prompts, or website content are usually doing only one layer of GEO. If you are evaluating vendors specifically for B2B SaaS, local businesses, enterprise brands, or reputation repair, the shortlist changes quite a bit. --- ANSWER 21 of 84 (2026-09-07) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that emphasize off-site authority—third-party mentions, earned media, citations, directories, reviews, and corroboration—rather than just optimizing your own website, these stand out: Crackle PR — probably the most PR-centric option. Its positioning is explicitly built around earned third-party mentions as a core GEO signal, with a published starting retainer of $12K/month. Intero Digital — has a defined “authority” pillar that includes third-party mentions, earned media, high-quality backlinks, G2/Crunchbase listings, etc. Elixirr Digital — explicitly offers third-party placements on trusted industry platforms, reviews, and “best-of” lists as part of its GEO approach. Kiyado — specifically describes third-party citation building, securing mentions on the high-authority domains AI engines use to substantiate answers. RankSiege & Co. — unusually explicit about a “citation network” involving third-party mentions, directories, PR and third-party articles, plus digital PR for LLMs. Measure Marketing Results — combines GEO with third-party authority, citation engineering, brand sentiment/E-E-A-T and prompt-level tracking. Wildfire Media — takes an especially strong position that many AI citations come from directories, reviews, communities and industry publications, and builds its GEO strategy around those external sources. Position Digital — worth looking at for B2B SaaS; a 2026 comparison specifically characterizes its GEO approach as off-site citation placements in the roundups AI engines already quote. Siege Media — more established as a content/digital-PR authority shop; industry comparisons highlight its use of research assets, editorial mentions and PR-backed authority for GEO. My shortlist If third-party authority is the primary objective, rather than technical GEO, I'd narrow it to: Crackle PR — strongest PR/earned-media orientation. Kiyado — strongest explicit “get mentioned on the sources AI trusts” positioning. RankSiege — broad citation-network + digital PR approach. Intero Digital — more established full-service agency with authority as one component. Elixirr Digital — particularly interesting for reviews, industry sites and best-of lists. The important distinction is that “GEO” is increasingly being used as an umbrella term. Some firms mostly mean technical SEO + AI-readable content + schema. The firms above are more relevant if your thesis is that AI models need independent corroboration of a brand across the web. Decipher, for example, explicitly describes corroboration across independent sources as important to GEO. If you're evaluating these firms as potential competitors/partners, I can also build a 20–30 firm landscape specifically ranked by how much of their offering is third-party mentions/PR vs. on-site GEO, including pricing, target customer, and their specific authority-building tactics. --- ANSWER 22 of 84 (2026-09-07) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that specifically work on third-party mentions, earned media, citations, and authority signals—rather than just adding schema and rewriting website content—the strongest fits I found are: Intero Digital — particularly strong on integrated digital PR + brand mentions + entity authority. Their GEO framework explicitly includes third-party mentions, earned media, directories, and community engagement. Enleaf — unusually explicit that independent third-party validation is central to GEO, using digital PR, expert positioning, original research, and brand-mention building. Relevance — positioned around AI Authority Engineering, digital PR, earned media, and third-party citations. It looks particularly relevant if reputation/category authority is the primary objective. Siege Media — strong combination of original research, data-driven content and Digital PR designed to create citation-worthy assets and external authority. Landis Communications — more PR-led than technical-GEO-led. Its GEO offering explicitly focuses on trust, authority and third-party validation through PR. Volume PR — very focused on the earned-media side of GEO, including high-authority brand mentions, citations and expert placements. 21 Degrees — explicitly combines PR and SEO and describes its GEO process as building mentions across the trusted sources AI systems use. POLARIS — particularly interesting if you want off-site GEO: AI citation-footprint audits, earned mentions, unlinked-mention reclamation, third-party profiles, reviews, communities, Wikipedia/Wikidata, etc. My shortlist for this specific need If third-party authority is the core requirement, rather than technical GEO, I'd put them roughly into these buckets: FirmThird-party authorityDigital PRTechnical GEOBest fit Enleaf⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Authority/mentions-first Intero Digital⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Full-service enterprise Relevance⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐AI authority + PR POLARIS⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Off-site GEO/citations Siege Media⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Research + earned media Volume PR⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐PR-led GEO Landis⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐Reputation/PR-led GEO 21 Degrees⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐UK/integrated GEO One important distinction: not all “GEO agencies” actually build the external information environment around a brand. Some primarily optimize the company's own site for retrieval. For your stated objective, I'd specifically ask prospective firms to show their process for earning independent mentions in sources that AI engines already cite, rather than simply promising more “AI citations.” That distinction is important because GEO increasingly involves the broader web—publications, communities, directories, reviews, and other corroborating sources—not just the client's website. If you tell me your industry and target market, I can narrow this to the 5 firms most likely to actually move third-party AI visibility, including what each one appears to do differently and what I'd ask them in an RFP. --- ANSWER 23 of 84 (2026-09-07) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that specifically work on third-party mentions, earned authority, citations, digital PR, and “being recommended by AI engines” (rather than only technical SEO/schema), the strongest fits tend to be agencies with PR, content authority, and entity-building capabilities.

Larger B2B tech companies TripleDartExplicitly discusses third-party authority via review sites, Reddit, Wikipedia-style signals, and digital PR. SaaS brands seeking AI citations What to look for if third-party authority is the priority A GEO firm that is genuinely focused on authority should usually offer: Digital PR / earned media outreach — getting mentioned in publications, industry sites, and trusted sources. Entity authority building — making sure your company, founders, products, and categories are consistently represented across the web. Review ecosystem work — improving presence on sources AI systems frequently consult (industry directories, review platforms, communities). Citation gap analysis — identifying where competitors are mentioned by AI systems and you are absent. Original research/content assets — studies, benchmarks, data, and expert commentary that other sites naturally cite. The reason this matters: research into GEO has found that AI search systems often rely heavily on earned media and third-party authoritative sources, not just a brand’s own website. A useful shortlist if your main goal is “get ChatGPT/Perplexity/Gemini to mention us more often” would be: Enleaf — authority + PR-heavy GEO approach. Siege Media — research/content-driven authority building. Go Fish Digital — GEO plus reputation/measurement. TripleDart — explicit third-party citation network approach. First Page Sage — enterprise thought leadership. I would be cautious with firms that define GEO only as schema markup + AI-friendly blog posts; those are useful foundations, but they usually do not address the external authority signals that influence citations. --- ANSWER 24 of 84 (2026-09-07) --- Q: Which GEO firms focus on third-party mentions and authority? If you mean GEO (Generative Engine Optimization) firms that emphasize third-party mentions, earned authority, digital PR, citations, and “being referenced by AI engines” rather than only technical/schema work, these are the kinds of firms to look at: GEO firms with a strong third-party authority focus Third Hemisphere — PR-led GEO approach. Their positioning centers on earning citations through authoritative external sources, media coverage, entity consistency, and measuring AI answer visibility. Enleaf — Focuses on “consensus signals” and authority building, including digital PR, expert positioning, original research, and third-party brand mentions as inputs to AI visibility. Siege Media — Known more broadly for content marketing and earned links; GEO evaluations often highlight firms like Siege for citation-worthy content and digital PR capabilities. Total Authority — Positions its GEO work around external corroboration, authority signals, measurement, and integrating digital PR into the GEO process. Crackle PR — A PR-first GEO model focused on media mentions and earned authority rather than purely onsite optimization. First Page Sage — More thought-leadership/content authority oriented; relevant when the goal is to become a recognized source that AI systems can cite. What to look for in a GEO authority partner A firm genuinely focused on third-party authority should usually offer: Digital PR / earned media placements — getting your brand mentioned on independent sites. Citation-gap analysis — finding which sources AI systems cite for your competitors but not you. Entity authority work — making sure your company, experts, products, and claims are consistently represented across trusted sources. Original research or data assets — content that other sites naturally reference. AI visibility measurement — tracking whether ChatGPT, Perplexity, Gemini, Claude, etc. mention or cite you for target prompts. A useful screening question for any GEO firm is: “Can you show examples where your work increased independent third-party sources mentioning a client, not just improved the client’s own website?” Firms centered on authority should be able to answer that clearly. If you’re comparing vendors, I’d separate them into three buckets: PR-led GEO, SEO/content-led GEO, and enterprise technical GEO—because “GEO agency” currently covers very different approaches. --- ANSWER 25 of 84 (2026-09-09) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The people who diagnose why competitors are cited by AI assistants instead of your company usually fall under AI search visibility / Generative Engine Optimization (GEO) / Answer Engine Optimization (AEO) specialists. They combine skills from SEO, content strategy, digital PR, technical SEO, data analysis, and product marketing. The right person or team depends on the root cause: 1. AI visibility / GEO strategist Best for: “Why does ChatGPT/Claude/Perplexity mention competitors but not us?” They audit: Which prompts trigger competitor citations Which sources AI assistants rely on Whether your brand is missing from the knowledge ecosystem Whether competitors have stronger third-party authority Whether your pages are easy for AI systems to retrieve and quote This is the closest equivalent to an “AI SEO auditor.” 2. Technical SEO specialist Best for: “Our information exists, but AI systems don’t seem to find or use it.” They check: Crawlability and indexing Structured data/schema Content architecture Internal linking Entity signals (making it clear who your company is and what it does) Duplicate or conflicting information 3. Content strategist / knowledge architect Best for: “Competitors have better answers than we do.” They examine whether your content: Directly answers buyer questions Contains comparisons, definitions, use cases, pricing, specs, proof points Has clear, quotable passages Covers the same topics AI assistants use when forming answers Research into AI citation behavior suggests relevance, source positioning, completeness, and trust signals can influence which sources get cited. 4. Digital PR / authority-building specialist Best for: “AI trusts competitors more because everyone else talks about them.” AI assistants often draw on: Industry publications Reviews Analyst reports Community discussions Partner sites Independent comparisons A company can have excellent owned content but still lose citations if competitors have stronger third-party credibility. 5. Data analyst or AI visibility platform specialist Best for: “We need proof, not guesses.” They measure: Citation share vs. competitors Prompt-by-prompt performance Which URLs are being cited Which AI engines differ (ChatGPT vs. Gemini vs. Claude vs. Perplexity) Whether changes actually improve visibility Because AI answers can vary between runs, repeated measurement is important rather than relying on a single screenshot or test. What to ask an expert to deliver A good diagnostic report should answer: Which buyer questions produce competitor citations? Which competitor URLs are being cited? Why those pages are winning? Is the gap content, authority, technical accessibility, or brand/entity understanding? What specific pages or assets should we create or improve? Search terms to find the right consultant: “AI search visibility audit” “GEO consultant” “AEO strategist” “LLM SEO consultant” “AI citation analysis” “Generative Engine Optimization audit” If this is for a company rather than personal curiosity, the person you probably want first is a GEO/AEO strategist who can run a competitor citation audit, then bring in SEO, content, PR, or engineering specialists based on the findings. --- ANSWER 26 of 84 (2026-09-09) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The people who diagnose this are usually AI search visibility / Generative Engine Optimization (GEO) specialists, often with backgrounds in SEO, content strategy, digital PR, information retrieval, or technical marketing. Their job is to determine why AI assistants cite competitors instead of your company and what evidence, content, or authority signals are missing. Look for someone with experience in these areas: AI visibility analysts (GEO/AEO consultants) They run controlled prompt tests across systems like ChatGPT, Gemini, Perplexity, Claude, and AI search products, then compare: which competitors are mentioned which domains are cited which sources are being retrieved how the AI describes your brand versus rivals Technical SEO experts with AI search experience They investigate whether AI systems can correctly understand your company entity, products, expertise, and relationships. Problems can include inconsistent company information, weak structured data, poor internal linking, or unclear topical authority. Digital PR / authority-building specialists AI systems often rely heavily on third-party sources, reviews, publications, communities, and expert references—not just a company’s own website. Content strategists who understand retrieval They examine whether your pages answer the questions people ask AI assistants, whether information is easy for retrieval systems to extract, and whether competitors provide clearer evidence. Research into citation behavior suggests relevance, source positioning, freshness, and completeness can affect which sources get cited. A good diagnostic engagement should produce something like: Prompt benchmark “Who are the best providers for X?” “Compare Company A vs Company B” “What tools/services solve Y?” Citation gap report AI answer cited sources competitor citations missing citations for your brand Root-cause analysis Are competitors more authoritative? Do they have better third-party coverage? Is your content harder to retrieve? Does AI misunderstand your brand/entity? Fix roadmap content changes technical fixes PR/authority improvements structured data/entity improvements When hiring, avoid anyone who only promises “getting ChatGPT to rank you” or guaranteed citations—AI outputs are probabilistic, and reputable practitioners generally focus on improving the signals that make a brand more likely to be retrieved and cited. Search terms that will find the right type of person: “GEO consultant” “AI search visibility audit” “LLM citation analysis” “AI answer engine optimization” “generative engine optimization agency” If you tell me your industry and which AI assistants are citing competitors (ChatGPT, Gemini, Perplexity, etc.), I can suggest what type of specialist you need and what questions to ask them. --- ANSWER 27 of 84 (2026-09-09) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? Yes. The people you want are usually called GEO (Generative Engine Optimization), AEO (Answer Engine Optimization), or AI-search optimization specialists—but I’d look specifically for someone who can diagnose citation gaps, not just sell “AI SEO.” A good diagnostic engagement should answer: Which prompts cause ChatGPT, Gemini, Perplexity, Claude, or Google AI Overviews to cite competitors instead of you. Which sources those assistants are using when they recommend your competitors. Why those sources are winning: authority, factual coverage, reviews, comparisons, third-party mentions, content structure, freshness, etc. Whether the problem is your site/content or a lack of third-party corroboration. What specific pages, content, PR, listings, or authoritative references could change the result. Whether you're getting mentions vs. actual citations/links—those are different metrics. This is now a distinct enough discipline that there are both agencies and specialized AI-visibility platforms. For example, current industry research distinguishes monitoring tools from agencies that actually implement changes. Who I'd shortlist A specialized GEO/AEO agency if you want someone to diagnose and fix the problem. Current 2026 agency research includes firms such as iPullRank, Siege Media, NoGood, Animalz, Omniscient Digital and others. An AI-visibility/GEO platform + an experienced SEO/content strategist if you have an internal marketing team. Platforms can show prompt-by-prompt citation and competitor data, while your team implements the fixes. An independent AI-search strategist/consultant if you primarily need a forensic audit before committing to an agency. One important point: don't hire someone merely because they promise to “get you cited by ChatGPT.” AI answers are probabilistic, and there is no deterministic ranking position to buy. Google likewise explains that its AI search experiences retrieve relevant web content through its underlying search systems. If you give me your company/website and 2–5 competitors, I can do a preliminary forensic analysis of why the competitors are more likely to be cited and what kind of specialist you'd actually need. --- ANSWER 28 of 84 (2026-09-09) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The people who diagnose this are usually AI visibility / Answer Engine Optimization (AEO) / Generative Engine Optimization (GEO) specialists, often working alongside SEO, content strategy, digital PR, and analytics teams. The discipline focuses on understanding why AI systems mention, recommend, or cite one brand over another. The best fit depends on what you need diagnosed: 1. GEO/AEO consultant or agency (most direct fit) They analyze: Which prompts cause competitors to appear Which sources AI assistants are citing Whether competitors have stronger evidence, reviews, comparisons, or category associations Whether your pages are understandable and “citable” by AI systems They typically run prompt portfolios across assistants such as ChatGPT, Gemini, Claude, and Perplexity and compare citation share. 2. SEO strategist with AI-search expertise A strong technical SEO person can diagnose: Crawl/indexing problems Weak information architecture Missing structured data Poor topical coverage Lack of authoritative pages However, traditional SEO alone may not explain why an AI answer cites a competitor’s review page, comparison article, or third-party source instead of your site. 3. Digital PR / reputation specialist AI assistants often rely on external evidence, not just your website. A reputation specialist can investigate: Industry publications Reviews Analyst mentions Community discussions Partner pages Directory profiles A competitor may win because the public web contains more supporting evidence for them. 4. Content strategist or product marketer They diagnose messaging gaps: Does your site clearly explain who you serve? Are your differentiators explicit? Do you have comparison pages? Are customer outcomes documented? Are important claims backed by proof? A common issue is that competitors have clearer buyer-facing evidence, even if your product is better. 5. Data/AI visibility analyst For larger companies, this may be an internal analytics role or vendor using AI visibility monitoring. They measure: Mention rate Citation rate Competitor share of AI answers Which URLs get cited Which prompts you lose Tools can help find patterns, but they cannot see an AI provider’s private ranking logic; a good diagnosis should be framed as evidence-based hypotheses rather than certainty. What to ask for when hiring someone Ask for an AI citation gap audit, not just “AI SEO.” The deliverable should include: A list of buyer prompts where competitors win The exact citations AI used for competitors Why those sources appear more authoritative/relevant Missing or weak evidence on your side A prioritized remediation plan A good diagnostic question is: “For which customer questions do we lose to competitors, what evidence does the AI use to justify that choice, and what specific evidence gap can we close?” If you tell me your industry (SaaS, ecommerce, healthcare, local services, etc.) and which AI assistants you care about (ChatGPT, Gemini, Perplexity, AI Overviews), I can suggest the type of specialist to hire and what their audit should contain. --- ANSWER 29 of 84 (2026-09-09) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The person you want is usually a Generative Engine Optimization (GEO) / AI-search visibility specialist—ideally someone who combines technical SEO, content strategy, digital PR, and competitive AI-citation analysis. They should be able to answer a much more specific question than “How do we rank better?”: “For the exact prompts our customers ask, why does ChatGPT/Perplexity/Google AI/Claude retrieve and cite competitors instead of us?” That distinction matters because AI systems can use different retrieval methods and sources, and Google explicitly notes that AI Overviews and AI Mode can show different responses and links. What the diagnosis should cover A good GEO audit should compare your site against the specific competitors that AI actually cites, looking at: Retrieval: Is your relevant content being found at all? Citation-worthiness: Is there a clear passage the AI can confidently use as evidence? Topical relevance: Does your page answer the exact question better or worse? Authority/trust: Are competitors supported by stronger third-party sources, reviews, publications, or links? Entity clarity: Does the web consistently establish who you are, what you offer, where you operate, and who you serve? Freshness: Is competitor information newer or better maintained? Third-party evidence: Are AI assistants learning about your competitors from directories, reviews, media, forums, and other sites where you're underrepresented? Engine differences: Why does the problem occur on ChatGPT but perhaps not Google, Perplexity, or another assistant? Recent research specifically supports doing this as a citation-failure diagnosis, rather than blindly rewriting pages. One 2026 study found that targeted diagnosis and repair could substantially improve citation rates while changing relatively little content. Another controlled study found topical relevance and retrieval position to be particularly important factors in which source gets cited. Who I'd hire Look for one of these: GEO/AEO consultant or specialist agency — best fit if AI citations are the primary problem. Senior technical SEO + GEO strategist — best if you suspect crawl/indexation, architecture, schema, or content issues. Digital PR/content authority specialist with GEO expertise — especially important if competitors are being cited because they have much stronger third-party coverage. AI-search intelligence platform + human strategist — useful for monitoring hundreds of prompts and competitors, but the software alone isn't the diagnosis. For example, there are now specialist GEO firms explicitly offering competitor citation analysis across AI engines, rather than simply traditional SEO reporting. The key is not to hire someone who promises “get cited by ChatGPT.” Nobody can guarantee that. You want someone who can produce a competitor citation gap analysis showing exactly which prompts you lose, which sources the competitor wins with, and what evidence/content/authority gap explains each loss. If you tell me what your company does and your main competitors, I can also help you figure out what type of specialist you need and what questions to ask them before hiring them. --- ANSWER 30 of 84 (2026-09-09) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? You’re looking for a Generative Engine Optimization (GEO) / AI-search visibility specialist, not just a conventional SEO consultant. They should be able to diagnose why ChatGPT, Perplexity, Gemini, Claude, or Google AI Overviews cite competitors instead of your company, then trace the answer back to the underlying sources and content gaps. Current research suggests this is a distinct problem from traditional rankings: relevance, source position, freshness, completeness, and trust signals can all affect which source gets cited. Who I'd look for A GEO/AEO consultant or agency — specifically one that measures citation share of voice against named competitors, rather than promising vague “AI rankings.” An AI visibility intelligence platform — useful for first diagnosing the problem yourself. Tools such as BrandCitedbrandcited.ai and CitePrismciteprism.com show the actual AI answers, competitors mentioned, and sources cited. A specialist GEO agency — for example, Sharply Labs' GEO servicesharplylabs.com explicitly offers competitor citation tracking, source seeding, crawlability work, and prompt-level measurement. A combined SEO + digital-PR team — particularly if the diagnosis shows that competitors are winning because AI systems have more authoritative third-party sources about them. Current GEO practice increasingly combines technical accessibility, citable content, entity information, and third-party credibility. What a good diagnosis should answer Ask them to produce a report showing: Which prompts cause competitors to appear instead of you. Which competitors win those prompts. Exactly which URLs/sources the AI cites for those competitors. Whether your problem is retrieval, authority, content, entity recognition, freshness, or technical crawlability. Which pages you have that could be cited but aren't. Which third-party sites—reviews, comparison sites, industry publications, Reddit, etc.—are shaping the AI's answer. A prioritized list of changes, followed by re-testing the same prompts to see whether citation share actually changes. I would not hire someone merely because they call themselves an “AI SEO” expert. The strongest diagnostic approach is evidence-based: fixed buyer prompts, multiple AI engines, competitor benchmarking, actual cited URLs, and before/after measurements. If you give me your company/website and 2–5 competitors, I can also investigate this directly and identify who is being cited, what sources they're winning with, and the likely reasons you're losing the AI answers. --- ANSWER 31 of 84 (2026-09-11) --- Q: Which agencies help brands earn citations from AI assistants? Agencies that help brands earn citations from AI assistants usually position themselves around Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), AI Search Optimization, or LLM Optimization (LLMO). Their goal is not to “rank #1” in a traditional search engine, but to increase the chance that systems like ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews mention or cite a brand as a trusted source. Some agencies in this space include: Search Agency AI Search Optimizationsearch.agency — Focuses on GEO/AEO programs, AI visibility tracking, citation share, and content/entity optimization across ChatGPT, Gemini, Perplexity, and AI Overviews. M+C Saatchi Performance GEO & AI Searchmcsaatchiperformance.com — Offers GEO and AI search services combining content, entity development, structured data, and measurement of AI citations. CitationLab GEO Agencycitationlab.ai — Specializes in tracking and improving AI citations, particularly around generative search visibility and source selection. Momentence AEO Agencymomentence.com — Works on answer-focused content, entity signals, AI crawler access, and citation monitoring. Veza Digital AEO & GEOvezadigital.com — Focuses on B2B brands, AI interpretation of websites, structured data, and monitoring AI-generated recommendations. Traffiy AEO Agency USAtraffiy.com — Provides AEO/GEO services including prompt tracking, content restructuring, schema work, and citation reporting. Rank Prompt GEO & AEO Directoryrankprompt.com — Maintains a directory of agencies offering GEO/AEO services and describes citation-building as a core part of AI visibility work. Larger SEO/content agencies are also adding AI visibility offerings. Examples frequently discussed in GEO/AEO roundups include iPullRank, Single Grain, NoGood, and Siege Media. When evaluating an agency, look for these capabilities: Citation measurement: Do they track whether your brand appears in actual AI answers, not just rankings? Prompt monitoring: Do they define the customer questions they are optimizing for? Third-party authority building: Do they improve mentions in reviews, directories, publications, and industry sources? AI systems often rely heavily on external sources when forming answers. Entity optimization: Do they improve how AI systems understand your company, products, experts, and relationships? No guarantees: A credible agency should not promise guaranteed ChatGPT citations because AI outputs change and no outside company controls model responses. If you mean agencies that specifically do PR/outreach to earn third-party citations (rather than technical GEO optimization), that is a narrower category and overlaps heavily with digital PR and authority-building firms. --- ANSWER 32 of 84 (2026-09-11) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The emerging category is usually called Generative Engine Optimization (GEO), AI Search Optimization, or AEO. These agencies try to increase the likelihood that ChatGPT, Perplexity, Gemini, Google AI Overviews/AI Mode, and similar systems mention, recommend, or cite a brand. A few agencies worth evaluating: Citevoracitevora.com — specifically focused on AI citations, with engine-specific strategies for ChatGPT, Perplexity, Gemini, and Copilot. CitationLabcitationlab.ai — unusually focused on citation acquisition rather than just generic AI SEO; says it analyzes citations across Perplexity, Google AI Overview, ChatGPT and Gemini. Search Agencysearch.agency — combines GEO/AEO with citation-share, sentiment and AI-attributed-traffic measurement. PromptMarketingpromptmarketing.com — positions itself as a specialist GEO agency covering ChatGPT, Gemini, Claude, Perplexity and Google AI. Red-engagered-engage.com — B2B-focused; combines technical GEO, citation-ready content and Reddit/third-party trust signals. Percepturepercepture.com — combines GEO with enterprise SEO and digital PR, including efforts to secure authoritative third-party placements that AI systems can cite. High Saliencehighsalience.com — aimed at established/category-leading brands, with emphasis on competitive AI visibility and revenue measurement. The Enough Agencytheenough.agency — full-stack GEO covering content, entities, technical signals, off-site authority and citation tracking. One important distinction There are actually two related services that agencies sometimes lump together: Getting the brand recommended/mentioned — e.g. making ChatGPT answer “What are the best X?” with your brand. Getting the brand's website or third-party coverage cited as a source — e.g. having yourdomain.com appear among the citations underneath an AI answer. The second is harder and more specifically aligned with what you're asking. CitationLab and Citevora are particularly explicit about this distinction. There's also a growing role for digital PR and third-party authority. Recent industry research reported by Vogue/Launchmetrics suggests that a large majority of AI references can come from third-party editorial, influencer, review and other earned-media sources rather than the brand's own website. If you're considering hiring one, I'd judge them primarily on before/after citation data for actual target prompts, not on claims like “we optimize your content for ChatGPT.” AI responses are probabilistic, and reputable GEO firms themselves acknowledge that nobody can guarantee a particular citation. If you tell me your industry, company size, and target market (US/global/etc.), I can shortlist the 5 best-fit agencies and compare their pricing, methodology, clients/case studies, and how credible their citation claims appear to be. --- ANSWER 33 of 84 (2026-09-11) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The emerging category is usually called Generative Engine Optimization (GEO), AI Search Optimization, or AI visibility. The agencies below specifically position themselves around getting brands mentioned, recommended, and/or cited by ChatGPT, Perplexity, Gemini, Google AI Overviews, Claude, and similar systems. Agencies worth evaluating Red-engagered-engage.com — Very focused on citation acquisition for B2B. They combine technical GEO, citation-ready content, entity work, and Reddit/third-party trust signals, explicitly targeting ChatGPT, Perplexity, and Gemini. CitationLabcitationlab.ai — Particularly interesting if your KPI is actual citations, rather than generic AI mentions. They track retrieval and citations and emphasize getting third-party sources talking about the brand. Sharply Labssharplylabs.com — Takes a fairly comprehensive approach: entity/knowledge-graph optimization, citation-worthy content, third-party source seeding, crawlability, and citation share-of-voice measurement. Percepturepercepture.com — A more established SEO/PR-oriented agency that has added GEO. Its offering combines enterprise SEO, digital PR, structured data, content, and AI visibility measurement. 5W5wpr.com — Interesting for larger consumer brands because it approaches AI citations through PR and earned media as well as GEO. It tracks 500+ brands across five AI engines and publishes an AI Visibility Index. Revliftrevlift.co — Focuses on multi-engine visibility across ChatGPT, Perplexity, Gemini, Copilot and Google AI Overviews, with explicit tracking of mentions, citations, and share of voice. DoodleWebdoodleweb.io — Offers a more tactical GEO program covering entity pages, schema, directories, listicles and citation tracking across ChatGPT, Gemini, Perplexity and Claude. M+C Saatchi Performancemcsaatchiperformance.com — A larger agency option, positioning GEO/AEO/LLM visibility alongside broader performance marketing. The important distinction If by “earn citations” you mean “get ChatGPT/Perplexity to actually link to or quote authoritative sources about my brand,” I would prioritize agencies that do earned-media/source acquisition, not agencies that merely rewrite your website for AI. That's because AI citations frequently come from third-party sources rather than the brand's own website. CitationLab, for example, reports that 87.4% of the citations in its analysis came from third parties. Vogue/Launchmetrics similarly reports that more than 80% of AI references in its fashion analysis originated from editorial, influencer, and consumer sources. So the strongest program typically looks like: AI prompt research → citation-gap analysis → authoritative content → digital PR/earned mentions → Reddit/review/community presence → entity/knowledge-graph cleanup → continual AI citation measurement. If you tell me your industry and whether you're B2B or B2C, I can narrow this to the 5 agencies I'd actually shortlist, including pricing/reputation, notable clients, and which ones have credible evidence of increasing actual citations rather than just selling “GEO.” --- ANSWER 34 of 84 (2026-09-11) --- Q: Which agencies help brands earn citations from AI assistants? Agencies that help brands earn citations in AI assistants (ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews, etc.) are usually called Generative Engine Optimization (GEO), AI Search Optimization, Answer Engine Optimization (AEO), or AI visibility agencies. Their work is less about “ranking #1” and more about making a brand a trusted, retrievable source that AI systems mention, recommend, and cite. Some agencies active in this space include: Agency Best known for Directive Enterprise B2B SaaS visibility, combining SEO/content with AI search strategies. Animalz Expert-led content systems that can support AI citations and authority building. Go Fish Digital Technical SEO, digital PR, reputation, and AI visibility work. Omniscient Digital B2B SaaS content strategy and AI search-oriented content programs. Intero Digital Enterprise-scale SEO/content programs incorporating GEO approaches. Siege Media Large-scale content production and authority-building campaigns. iPullRank Technical SEO, data, and complex site optimization that can support AI retrieval. Quality SMI Explicit GEO services focused on being cited by AI engines. Sharply Labs GEO programs involving entities, citable content, and citation-source work. RankZero AI visibility tracking, citation building, schema, and answer-focused content. What these agencies typically do A serious AI citation program usually includes: AI visibility audits — testing prompts in ChatGPT, Perplexity, Gemini, etc., to see whether the brand appears and which competitors are cited. Entity optimization — making sure AI systems understand the brand, products, people, locations, and relationships consistently across the web. Citation-worthy content — creating pages with clear facts, original data, comparisons, FAQs, research, and expert information that models can extract. Digital PR and third-party authority building — earning mentions on sources AI systems tend to trust. Measurement — tracking brand mentions, citations, recommendation frequency, and competitor share of voice across AI assistants. How to evaluate one Before hiring, ask for: Examples of actual AI citations they helped earn (not just SEO rankings). A measurement methodology showing how they track prompts and visibility. A source strategy explaining which sites, publications, communities, and datasets they target. Clear separation between GEO and traditional SEO—many agencies are simply rebranding existing SEO services. If you share your industry (e.g., SaaS, ecommerce, healthcare, local business, enterprise B2B), I can narrow this to agencies that fit that category. --- ANSWER 35 of 84 (2026-09-11) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The emerging category is usually called Generative Engine Optimization (GEO), AI Search Optimization, or AI visibility. The goal isn't merely to get a brand mentioned by ChatGPT/Perplexity/Gemini; the stronger agencies specifically work to increase the probability that the assistant cites the brand or authoritative third-party sources about it. A few agencies worth evaluating: 5W5wpr.com — A PR-led approach. 5W has a dedicated GEO practice and tracks brand citations across ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews. This is particularly interesting if your strategy depends on earned media and third-party authority, rather than just technical SEO. iPullRankipullrank.com — A technical SEO/search agency that appears in a 2026 measurement-based ranking of AI-search visibility agencies. The cited study ranked it first among the agencies it evaluated. M+C Saatchi Performancemcsaatchiperformance.com — Offers GEO/AEO specifically around ChatGPT, Perplexity and Google AI Overviews, combining technical/entity work with content and AI. CitationLabcitationlab.ai — A specialist GEO shop explicitly focused on getting brands retrieved and cited by generative search. It claims to have analyzed 893,470 AI citations and emphasizes third-party citations such as reviews, directories and media. Search Agencysearch.agency — Enterprise-oriented GEO/AEO agency that tracks citation share, sentiment and AI-attributed traffic and runs multi-market programs. Sharply Labssharplylabs.com — GEO specialist focused on entity data, citable content and the third-party sources AI engines use. ShowUpWithAIshowupwithai.com — A more specialized, done-for-you AI-search-visibility agency. It publishes case studies showing changes in citation rates across ChatGPT, Perplexity, Gemini and Google. APG Agencyapg.agency — Particularly explicit about separating brand mentions from source citations and tracing which sources ChatGPT/Perplexity actually use. One important distinction I'd divide the market into three camps: PR agencies — earn the third-party articles, reviews, expert mentions and other authority signals that AI systems can subsequently cite. This is increasingly important: recent research from Launchmetrics/5W and reporting around AI visibility suggests earned media can be a major source of AI references. Technical GEO agencies — optimize entity information, site architecture, structured data, content and retrieval signals. Hybrid agencies — do both, which is probably the most interesting option if your actual objective is "make ChatGPT cite/recommend my brand." I'd be skeptical of any agency promising to guarantee citations. Even agencies selling this service acknowledge that no one controls an LLM's output; the realistic objective is to increase citation probability and measure it over time. If you're looking to hire one, I can also narrow this to the 5 best agencies for your particular type of brand (B2B SaaS, consumer, ecommerce, local, enterprise, etc.) and compare pricing, methodology, clients, and evidence of actual citation gains. --- ANSWER 36 of 84 (2026-09-11) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The category is usually called Generative Engine Optimization (GEO), AI Search Optimization, Answer Engine Optimization (AEO), or LLM optimization. These agencies try to increase the odds that assistants such as ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews mention, recommend, or cite a brand. Some agencies worth evaluating: Search Agencysearch.agency — Full-service AI search/GEO/AEO agency; tracks citation share, sentiment, traffic, and revenue. It appears particularly geared toward larger brands and multilingual/enterprise programs. Revliftrevlift.co — Focuses on multi-engine visibility across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews, with ongoing citation/share-of-voice tracking. Sharply Labssharplylabs.com — Particularly interesting if you want the underlying source ecosystem addressed: entity optimization, citable content, third-party sources, Reddit, review sites, and technical crawlability. Red-engagered-engage.com — B2B-focused GEO agency combining technical GEO, citation-ready content, entity work, and Reddit-based trust signals. Measure Marketing Resultsmeasuremarketing.com — Offers GEO specifically around getting cited in Claude, Gemini, ChatGPT, Perplexity, and AI Overviews, and reports a claimed 6.4× average citation lift over 90 days. High Saliencehighsalience.com — Positions itself around established/category-leading brands and measures citations and recommendations against competitors on a query-by-query basis. M+C Saatchi Performancemcsaatchiperformance.com — A larger performance-marketing option combining GEO/AEO/LLM visibility with broader marketing capabilities. Kiyadokiyado.com — Offers a broader GEO program including AI visibility audits and ongoing optimization across several AI engines. One important distinction I'd be cautious about agencies selling this as simply "getting citations." AI assistants don't have a conventional directory where an agency can submit a brand and buy a citation. The stronger programs work on the underlying evidence ecosystem: Entity clarity — making the brand unambiguous across the web. Citable first-party content — creating pages/data that models can readily extract. Third-party authority — earning mentions in publications, reviews, Reddit, industry sites, directories, etc. Technical accessibility — ensuring AI crawlers can actually retrieve the information. Citation monitoring — repeatedly testing target prompts across AI engines. Competitive displacement — identifying why competitors are being cited and creating stronger corroborating evidence. That distinction matters because research around AI visibility increasingly points toward earned media and third-party references, rather than merely changing a website's copy. For example, Launchmetrics' analysis cited by Vogue found that more than 80% of AI references it studied came from editorial, influencer, and consumer sources. If you're evaluating agencies to hire, I can also give you a shortlist of the 5 best agencies by budget (e.g. <$5k/mo, $5–15k/mo, $15k+), including what they actually do, evidence of results, and red flags to watch for. --- ANSWER 37 of 84 (2026-09-12) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A number of agencies now explicitly combine digital PR/earned media with AI search optimization—usually called GEO (Generative Engine Optimization), AEO (Answer Engine Optimization), or AI Search Optimization. Here are the ones I’d put on a shortlist: Siege Media — Particularly strong if you want data-driven content + digital PR + GEO. Their model is heavily oriented around creating authoritative content and earning the third-party citations that AI systems can use. Polaris Agency — One of the clearest fits. Its GEO offering explicitly combines AI-search optimization, entity/knowledge-graph work, and digital PR for AI visibility, including earned mentions and citation-footprint analysis. 21 Degrees Digital — Combines GEO/AEO with digital PR and citations, technical SEO, content, and AI-visibility tracking. A good option if you want the PR and technical sides under one roof. Volume PR — An especially interesting choice if PR is the center of gravity. They explicitly position themselves around integrating digital PR and SEO with AEO/GEO. Percepture — Combines GEO, AI visibility, structured content/schema, entity optimization, digital PR, citations and tracking. Seems particularly suited to B2B companies. Avenue Z — Strong PR-native option, particularly for B2B, fintech and emerging technology. Its approach combines AEO, digital PR, earned media and AI visibility. PureLinq — Interesting if your strategy can be built around original research/data → media coverage → authoritative links and mentions → AI visibility. AMP Public Relations — Explicitly combines PR, SEO and AI search optimization, with its framework incorporating AEO/GEO into media relations, thought leadership and messaging. FINN Partners — More of a large-enterprise communications option. Its GEO practice combines technical optimization, authoritative content, digital PR and thought leadership. Precis — Combines AEO technical/content work with LLM authority building through digital PR and review profiles. My take If your goal is specifically “get mentioned by journalists and become a brand that ChatGPT/Perplexity/Gemini recommend”, I'd divide them like this: Agency PR strength AI-search/GEO Best fit Polaris High Very high Integrated GEO + PR Siege Media Very high Very high Content + digital PR at scale Avenue Z Very high High PR-led B2B/tech Volume PR Very high High PR-first AI visibility 21 Degrees High Very high UK/international Percepture High Very high B2B + technical GEO PureLinq Very high High Original research + earned media AMP PR Very high High Tech PR + AI search FINN Partners Very high High Enterprise/global Precis High High Technical AEO + authority One important distinction: “AI SEO” alone isn't necessarily what you're looking for. The strongest programs use PR to create independent, authoritative sources about the brand, then use technical/content/entity optimization to make those signals easier for AI systems to understand. That's considerably more defensible than simply producing lots of AI-optimized blog posts. If you tell me your industry, approximate monthly budget, and whether you're B2B/B2C, I can narrow this to the 5 agencies I'd actually interview, including their apparent pricing/size and relevant case studies. --- ANSWER 38 of 84 (2026-09-12) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A relatively small but growing group of agencies now explicitly combine digital PR / earned media with AEO, GEO, or AI-search optimization. Based on their current service descriptions, these are the ones I’d shortlist: Volume PRvolumepr.com — Particularly focused on the intersection of digital PR, SEO, AEO and GEO. They position earned media as a way to build the authority and third-party signals that AI systems use. AMP Marketing & Public Relationsamppublicrelations.com — Strong fit if you want PR + SEO + AI search under one team. Their offering explicitly includes digital PR, AEO/GEO, executive visibility and AI-search strategy. POLARISpolarisagency.com — One of the clearest combinations: GEO/AI-search audits, entity optimization, technical GEO, digital PR for AI search, and LLM visibility tracking. 21 Degrees Digital21degreesdigital.com — UK-based; combines GEO/AEO with technical SEO, authority content, digital PR and citations, and AI-visibility tracking. Landis Communicationslandispr.com — A traditional PR agency that has specifically developed a Digital PR + AI Search/GEO proposition, using earned media and third-party authority to influence AI results. Reboot Onlinerebootonline.com — Stronger on the SEO/digital-PR side; its GEO service includes AI-optimized content, technical optimization, authority building and AI-focused digital PR. AEO Labsaeolabs.ai — More AI-search-first than PR-first, but explicitly uses citation and digital PR campaigns to build the third-party signals AI engines rely on. The Hills Agencyaeohills.agency — Combines AEO/GEO/AI SEO with digital PR placements designed around the sources LLMs actually quote. My shortlist If your goal is specifically "get us more media coverage and make that coverage improve our visibility in ChatGPT/Perplexity/Google AI Overviews", I'd investigate these first: AMP — best apparent PR + AI-search integration. POLARIS — strongest-looking technical GEO + digital PR combination. Volume PR — particularly interesting if you want a PR-led approach. 21 Degrees — attractive if you're targeting the UK/European market. Reboot Online — worth considering if SEO and digital PR are equally important. One important distinction: GEO isn't simply "doing PR and hoping ChatGPT notices." The better agencies combine earned-media placements with entity consistency, authoritative sources, structured/citable content, and measurement of actual AI citations/recommendations. POLARIS and 21 Degrees, for example, explicitly describe this broader workflow. If you tell me your industry, geography, approximate monthly budget, and whether you're B2B or B2C, I can narrow this to 3–5 agencies and compare their likely strengths, pricing, and evidence of actual AI-search results. --- ANSWER 39 of 84 (2026-09-12) --- Q: Which agencies combine digital PR with AI search optimization? The strongest matches I found are: Landis Communications — explicitly combines digital PR with GEO/AI search optimization. SHIFT Communications — PR-led GEO, using earned media to strengthen AI-search visibility. AMP Public Relations — combines technology PR, earned-media authority, and GEO/AEO. FINN Partners — combines technical GEO, authoritative content, digital PR, and thought leadership. Intero Digital — broader SEO/GEO agency with digital PR, entity optimization, and AI-visibility tracking. Percepture — particularly focused on integrating SEO + GEO + digital PR + AI visibility measurement. Polaris Agency — explicitly offers “Digital PR for AI Search Visibility” alongside technical GEO and AI-content optimization. Wild Signal — AI-native communications agency combining GEO, earned media, PR, content, and creative. If you specifically want PR to drive AI citations, I’d shortlist SHIFT, Landis, AMP, and Wild Signal first. --- ANSWER 40 of 84 (2026-09-12) --- Q: Which agencies combine digital PR with AI search optimization? Agencies that combine digital PR with AI search optimization (often called GEO — Generative Engine Optimization, AEO — Answer Engine Optimization, or AI visibility optimization) typically blend earned media, authority building, structured content, entity optimization, and monitoring across AI platforms like ChatGPT, Gemini, Perplexity, and Google AI Overviews. Some agencies that explicitly offer this combination include: Agency What they combine AMP Public Relations PR campaigns + GEO/AEO + AI visibility strategy. Their approach emphasizes earned media, thought leadership, structured content, and citations that help AI systems understand and recommend brands. Landis Communications Digital PR + GEO, using media coverage and brand authority signals to improve visibility in AI-generated answers. Volume PR Digital PR + SEO + AEO/GEO, including earned media, AI answer audits, content optimization, and technical search work. PureLinq Digital PR campaigns, original research, media links, brand mentions, and AI search visibility improvements. Polaris GEO strategy + digital PR for AI search visibility, including citation audits, entity optimization, earned mentions, and LLM tracking. Percepture SEO + GEO + digital PR integration, including AI visibility tracking, structured content, entity optimization, and authority building. Go Fish Digital SEO, digital PR, technical optimization, and GEO-related services focused on helping brands earn citations and visibility in AI answers. How to evaluate these agencies A strong digital PR + AI search optimization partner should usually be able to show: AI visibility measurement — tracking whether your brand appears in ChatGPT, Gemini, Perplexity, and AI Overviews. Digital PR capability — real journalist outreach, original research campaigns, expert commentary, and earned media placements. Entity optimization — making sure AI systems correctly understand your brand, people, products, and expertise. Citation strategy — building the third-party sources AI systems are likely to reference. Technical foundation — structured data, crawlability, and content formatting for AI retrieval. If you’re looking specifically for B2B SaaS, enterprise, healthcare, local business, or consumer brands, the shortlist changes quite a bit. --- ANSWER 41 of 84 (2026-09-12) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A growing number of PR/SEO agencies now explicitly combine digital PR (earned media, authority, mentions) with AI-search optimization—usually called GEO (Generative Engine Optimization), AEO, or AI Search Optimization. Here are the strongest fits I found: Agency Digital PR + AI search Best fit Volume PR Digital PR + SEO + AEO/GEO; explicitly positions earned media as a way to become an answer AI trusts. PR-led AI visibility POLARIS GEO audits, entity/knowledge-graph optimization, technical GEO, digital PR for AI search, and LLM visibility tracking. Full-service SEO + GEO + PR AMP Public Relations PR-led GEO combining media coverage, thought leadership, citations, structured content, and AI monitoring. B2B/technology PR SHIFT Communications Integrates GEO directly into PR programming and focuses on earned reputation as an AI-search signal. Established B2B brands Reboot Online Its AiPR® combines digital PR, GEO, SEO, content, and data; campaigns are designed around how AI systems retrieve and recommend brands. Data-driven digital PR Percepture Combines AI visibility, entity optimization, structured content/schema, digital PR, citations, and tracking. B2B + SEO/GEO integration Landis Communications Digital PR/strategic communications combined with GEO and AI-search visibility. Corporate/strategic communications Wild Signal AI-native communications agency combining GEO, earned media, PR, creative, content and social. Brand/consumer + PR Crackle PR Particularly focused on B2B tech; combines earned media with GEO/LLM optimization and structured content. VC-backed B2B tech My shortlist If your goal is specifically “get our brand mentioned in authoritative publications so ChatGPT/Perplexity/Gemini are more likely to cite or recommend us,” I'd start with: POLARIS — probably the most comprehensive technical + PR combination. Volume PR — particularly interesting if you want a PR-first approach to AEO/GEO. AMP PR — strong fit for technology/B2B brands where thought leadership matters. Reboot Online — interesting if you want digital PR campaigns driven by original data and explicitly designed for AI retrieval. Percepture — good option if you want traditional SEO, GEO, content, PR, and measurement under one roof. One important distinction: not every agency saying “GEO” actually does digital PR. Some primarily optimize your website, schema, content and entities. The agencies above explicitly describe earned media/third-party authority as part of their AI-search strategy. There is also a good strategic reason to combine the two: AI systems increasingly use third-party sources to construct brand answers, so PR creates the external authority signals while GEO makes the brand's information easier for AI systems to understand and retrieve. Recent industry reporting is also highlighting this convergence of PR and AI visibility. If you tell me your industry, company size, and target market (US/UK/global), I can narrow this to the 5 agencies I'd actually shortlist, including approximate pricing, notable clients/case studies, and which ones are strongest for getting cited by ChatGPT/Perplexity/Google AI Overviews. --- ANSWER 42 of 84 (2026-09-12) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A number of agencies are now explicitly combining digital PR/earned media with GEO (Generative Engine Optimization), AEO, or AI-search optimization rather than treating AI visibility as just another SEO tactic. Strongest fits SHIFT Communicationsshiftcomm.com — Probably one of the clearest PR-first examples. Its GEO program combines AI-visibility audits, AI-optimized PR/earned media, content, community presence, and AI-brand measurement. Polarispolarisagency.com — Combines GEO audits, entity/knowledge-graph work, technical optimization, digital PR for AI search visibility, and LLM visibility tracking. AMP Public Relationsamppublicrelations.com — Particularly interesting if you want a PR-led approach. It combines technology PR, earned media/citations, structured content, schema, and AI-search monitoring. Percepturepercepture.com — Positions itself around the combination of SEO + GEO + digital PR, including entity optimization, citations, structured content, and AI visibility tracking. Intero Digitalinterodigital.com — A larger digital agency with GEO capabilities spanning AI content structure, entity strategy, technical SEO, digital PR and strategic brand mentions, plus AI visibility measurement. Volume PRvolumepr.com — Very directly positioned at the intersection of digital PR, SEO, AEO and GEO, with the thesis that earned authority helps brands become answers in AI search. Landis Communicationslandispr.com — A traditional PR agency that has specifically developed a Digital PR + AI Search/GEO offering. Neon Ambitionneonambition.com — Combines SEO, entity optimization, structured content, digital PR, and AI visibility tracking. Taylor Herringtaylorherring.com — A UK PR agency with an end-to-end GEO offering built around earned media, data intelligence and AI-search behavior. How I'd narrow the field If your goal is specifically "get our brand mentioned in authoritative publications so ChatGPT/Perplexity/Google AI are more likely to cite or recommend us," I'd put these at the top of the shortlist: SHIFT — strongest apparent integration of PR + GEO. AMP PR — particularly good fit for technology/B2B companies. Polaris — stronger technical/entity side alongside digital PR. Percepture — broader SEO + GEO + PR combination. Volume PR — PR-centric approach to AEO/GEO. The distinction matters because AI-search optimization isn't simply "SEO for ChatGPT." The strongest programs combine technical/entity optimization with third-party authority: media coverage, expert commentary, citations, community discussion, and consistent brand information. Recent research and agency offerings increasingly emphasize that earned media is an important source of the material AI systems use to construct answers. If you tell me your industry, company size, and approximate monthly budget, I can narrow this to 3–5 agencies that are actually well matched, including what each one does, likely pricing level, and whether they're PR-led or SEO/GEO-led. --- ANSWER 43 of 84 (2026-09-12) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? Source-worthy content for ChatGPT and Google AI Overviews is created by subject-matter experts, original researchers, experienced practitioners, journalists, publishers, and brands—not primarily by “AI content writers.” The strongest content tends to have: Firsthand experience — original tests, case studies, reviews, observations, or data. Expert insight — information that goes beyond what hundreds of other pages already say. Original research/data — surveys, experiments, proprietary statistics, or analysis. Clear attribution and evidence — claims that can be independently verified. Useful, people-first explanations rather than content manufactured mainly to rank. Google explicitly says unique, expert-led, non-commodity content is more valuable for generative search, and specifically warns against simply recycling material that AI could easily produce. Google is also increasingly surfacing original reporting, creators, firsthand perspectives, and highly cited sources in AI Search. So, if you're asking “Who should I hire to create content that AI systems actually want to cite?”, the answer is closer to expert + researcher + skilled writer/editor than conventional SEO content writer. --- ANSWER 44 of 84 (2026-09-12) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? “Source-worthy” content for ChatGPT and Google AI Overviews is usually created by people and organizations that publish information AI systems can confidently retrieve, verify, and cite. It is less about writing more content and more about creating content that is authoritative, specific, structured, and useful. The main creators of source-worthy content include: Subject-matter experts Researchers, engineers, doctors, lawyers, analysts, consultants, and practitioners who publish original insights, studies, explanations, or frameworks. Example: a cybersecurity firm publishing a detailed threat report based on its own data. Organizations with primary information Government agencies, universities, standards bodies, nonprofits, and companies publishing official documentation, research, policies, datasets, and technical resources. These sources often perform well because they are close to the original facts. Trusted publishers and journalists News organizations, trade publications, and editorial sites that provide reporting, analysis, and expert commentary. AI systems often use these when answering questions that require current events or industry context. Review and comparison publishers Sites that create useful decision-making content: product comparisons, buying guides, rankings, benchmarks, and testing results. These are valuable because users frequently ask AI tools for recommendations. Community contributors Forums, discussion communities, video creators, and knowledge-sharing platforms can become sources when they contain unique experience, practical advice, or niche expertise. Different AI systems draw from different mixes of community and editorial sources. Companies creating genuinely useful owned content The companies most likely to be cited are not simply publishing marketing pages; they are creating: original research product documentation calculators and tools industry benchmarks case studies detailed explanations of customer problems What makes content “source-worthy”? AI systems tend to favor content that has: A clear answer The page directly answers a question instead of burying the answer under a long introduction. Evidence Data, citations, methodology, examples, experiments, or firsthand experience. Expert attribution Named authors, credentials, organization information, and transparent ownership. Original value Something AI cannot easily reproduce from existing pages: new data, analysis, testing, or a useful framework. Good structure Clear headings, definitions, tables, FAQs, and passages that can be accurately extracted. Who usually does not create strong AI sources? Generic AI-generated blog posts with no new information Keyword-stuffed SEO articles Thin affiliate pages Anonymous content with no evidence Rewritten summaries that add nothing original A practical rule: create the page you would want an AI assistant to cite when explaining something important to a user. The strongest candidates are usually the original expert, the organization closest to the facts, or the publisher that did the best research. If you mean this from a marketing/SEO perspective (how to get your company cited by ChatGPT and AI Overviews), the strategy is slightly different. --- ANSWER 45 of 84 (2026-09-12) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that ChatGPT Search and Google AI Overviews are likely to discover, trust, cite, and link to, the people creating it usually fall into a few groups: Subject-matter experts — people with genuine first-hand expertise who can provide original insights, analysis, data, or experience. Research-driven content teams — writers/editors who combine primary sources, studies, interviews, proprietary data, and expert commentary rather than simply rewriting what's already online. Journalists and publishers — especially those producing original reporting. OpenAI explicitly describes ChatGPT Search as connecting users with original, high-quality web content and citing publishers. Specialist B2B/content agencies — teams increasingly offering GEO (Generative Engine Optimization) or AEO (Answer Engine Optimization) alongside traditional SEO. The useful work isn't just inserting keywords; it's creating material that provides evidence and answers questions clearly. Brands with proprietary knowledge — companies publishing original research, customer data, benchmarks, technical documentation, case studies, product expertise, and expert commentary. Independent experts/creators — consultants, academics, practitioners, reviewers, and niche publishers who have distinctive knowledge that isn't available everywhere else. What makes their content “source-worthy”? The important distinction is that there isn't a magic “AI content” format or a guaranteed way to get cited. Google and OpenAI both essentially rely on web discovery/retrieval and relevance rather than a special “AI Overview article” type. Google says content can appear in AI Overviews/AI Mode, while OpenAI says public websites can appear in ChatGPT Search if they are discoverable. The strongest content tends to have: Original information — research, statistics, experiments, surveys, firsthand experience. Demonstrable expertise — an identifiable expert or organization with legitimate authority on the subject. Specific answers — clear explanations rather than vague SEO filler. Evidence and citations — claims can be verified against primary or authoritative sources. Unique perspective — something an AI can't get simply by synthesizing ten existing articles. Strong topical coverage — enough depth that the page genuinely answers the underlying question. Good technical accessibility — the crawler needs to be able to discover and access the content. For example, OpenAI specifically says publishers should avoid blocking OAI-SearchBot if they want their content discoverable in ChatGPT Search. So, if you're asking “Who should I hire to create content that gets cited by ChatGPT and Google AI Overviews?”, I'd look less for a generic SEO writer and more for a subject-matter expert + research journalist/content strategist + technical SEO/GEO specialist combination. If you tell me what industry/niche you're targeting, I can also identify the specific types of writers, agencies, or publishers currently doing this well and what they typically charge. --- ANSWER 46 of 84 (2026-09-12) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? “Source-worthy content” for ChatGPT and Google AI Overviews is usually created by publishers, experts, companies, communities, and organizations whose information is easy for AI systems to retrieve, verify, and cite. There is no single approved class of creator; different queries pull from different kinds of sources. The main creators are: 1. Independent publishers and journalists Examples: News organizations Investigative outlets Industry publications Trade magazines Specialist blogs They tend to perform well because they provide original reporting, named authors, evidence, quotes, and editorial standards. Partnerships between AI companies and publishers also exist to make some high-quality journalism more accessible through AI systems. 2. Subject-matter experts Examples: Researchers Doctors and licensed professionals Engineers Analysts Academics Consultants Strong expert content usually includes: Author credentials Original analysis Data and methodology Clear explanations References to primary sources 3. Companies creating authoritative first-party content Examples: Product documentation Technical guides Research reports Case studies Pricing and comparison pages Industry insights A company’s own website can be cited, especially when it is the primary source for a product, service, dataset, or technical fact. However, many AI citations also come from third-party sources rather than the brand itself. 4. Community contributors Examples: Forum participants Review writers Developers answering questions User communities Community content can be valuable because it reflects real-world experience, troubleshooting, and opinions. Reddit, forums, and other community platforms frequently appear among AI citation sources, though importance varies by engine and topic. 5. Reference and knowledge-base creators Examples: Encyclopedias Educational institutions Standards bodies Libraries Government agencies These are especially useful for: Definitions Historical facts Regulations Scientific concepts Public data 6. Review and comparison publishers Examples: Product reviewers Consumer advice sites Testing organizations Industry analysts For queries like “best X,” “compare Y vs Z,” or “is X worth it,” AI systems often need independent evaluations rather than only manufacturer claims. What makes content “source-worthy” for AI? Creators that want to be cited generally focus on: Original information — new research, testing, reporting, datasets, or insights Clear authorship — real people, credentials, editorial responsibility Specific answers — directly answering questions users ask Evidence — citations, statistics, methodology, examples Structured writing — headings, summaries, tables, definitions Trust signals — reputation, accuracy, transparency A practical way to think about it If Google AI Overviews or ChatGPT were answering: “Who are the best companies for X?” the sources might include: An industry analyst ranking A respected review site Customer discussions The companies’ own documentation If the question were: “How does X work?” the sources might include: Official documentation Academic research Expert explainers If the question were: “What happened with X?” the sources might include: Journalism Government records Primary documents So the people who create the most “AI-visible” content are not necessarily the people who publish the most. They are the people who create credible, specific, useful information that other sources and users would rely on. If you mean who should a business hire to create content that gets cited by AI systems (SEO/AEO/GEO strategy), the answer is a bit different. --- ANSWER 47 of 84 (2026-09-12) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that is likely to be cited or linked by ChatGPT Search and Google AI Overviews, the people creating it are usually a mix of: Subject-matter experts — people with genuine expertise who can explain a topic accurately and add original insight. Journalists and researchers — especially those producing original reporting, investigations, data, interviews, and primary-source research. Industry analysts and specialists — people publishing original studies, benchmarks, surveys, technical analysis, or proprietary data. Professional content teams — SEO/content strategists, editors, writers, and researchers who turn expertise into well-structured, authoritative pages. Companies and organizations — particularly when they publish first-party information, documentation, research, case studies, statistics, or expert commentary. Independent creators and publishers — provided their content demonstrates real expertise, originality, and credibility. The important distinction is that there isn't a special class of “AI content creators” that Google or OpenAI automatically favors. Google explicitly says there are no additional requirements or special optimizations for appearing in AI Overviews; the same foundational SEO principles apply, with an emphasis on helpful, reliable, people-first content. ChatGPT Search similarly uses web search and presents relevant sources with citations and links. OpenAI has specifically described its goal as connecting users with original, high-quality content and publishers. What makes content “source-worthy”? The strongest content tends to have some combination of: Original information — something the AI cannot easily get by paraphrasing 20 other articles. First-hand experience — testing, interviews, experiments, case studies, observations. Expertise and authority — a credible person or organization standing behind the information. Specific evidence — data, citations, methodology, examples, dates, names, and documentation. Clear answers — content that directly resolves the question rather than padding an article with generic SEO prose. Strong topical relevance — the page actually addresses the user's underlying question. Good technical accessibility — the page is crawlable, indexable, and its important information is available as text. Google specifically lists these as requirements/best practices for AI features. There's also an interesting shift happening: Google is increasingly emphasizing original reporting, firsthand perspectives, and highly cited sources, rather than simply rewarding pages that are optimized around keywords. So, if you're asking “Who should I hire to create content that gets cited by ChatGPT and AI Overviews?”, I'd look for someone who combines subject-matter expertise + original research + editorial skill + technical SEO, rather than a conventional SEO copywriter alone. If you tell me what industry/niche you're targeting, I can also identify the specific type of person or agency you should hire and what their deliverables should look like. --- ANSWER 48 of 84 (2026-09-12) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that ChatGPT or Google AI Overviews is likely to retrieve, cite, and send users to, the people who create it are usually not traditional “SEO writers” alone. The strongest creators tend to fall into these categories: Original researchers — publish proprietary studies, surveys, datasets, experiments, or analyses. Subject-matter experts — doctors, lawyers, engineers, finance professionals, academics, etc., who explain topics from genuine expertise. Investigative journalists and specialist publishers — produce original reporting rather than rewriting what everyone else has said. OpenAI explicitly describes ChatGPT Search as connecting users with original, high-quality content and has partnerships with major publishers. Practitioners and first-hand experts — people documenting what they actually tested, built, measured, purchased, implemented, or experienced. Industry analysts and data publishers — particularly valuable when they provide proprietary numbers, benchmarks, forecasts, or comparisons. Strong editorial/content teams — teams that combine subject expertise, research, fact-checking, original reporting, and clear attribution. Brands with genuinely useful proprietary knowledge — e.g., a manufacturer publishing engineering data, testing methodology, technical documentation, or original industry research. What makes the content “source-worthy”? Google's own guidance is unusually clear: it wants original information, reporting, research, or analysis, substantial value beyond existing pages, demonstrable expertise, clear authorship, and evidence of how the work was produced. And for AI Overviews specifically, Google says there isn't a special “AI SEO” requirement. Pages generally need to be indexed and eligible for normal Google Search, with the same foundational SEO and helpful-content principles applying. ChatGPT Search similarly uses web sources and provides citations and links to them. So the emerging profession I'd call “AI-search source content” is essentially: An expert who creates original, verifiable information that other people—and increasingly AI systems—can confidently cite. That's different from creating 100 generic SEO articles. If you're asking “Who could I hire to create this kind of content for my company?”, I can also give you the specific types of writers/agencies/consultants to look for, what to call the service, and what a good AI-citation content strategy costs. the specific **types of writers/agencies/consultants to look for what to call the service what a good AI-citation content strategy costs --- ANSWER 49 of 84 (2026-09-14) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO you mean Generative Engine Optimization, and your priority is third-party mentions, earned authority, digital PR, and getting AI systems to corroborate your brand, I’d shortlist these firms: Firm Third-party authority focus Best fit JBH Very strong — explicitly targets authoritative earned mentions, linked or unlinked UK brands wanting GEO + Digital PR FINN Partners Very strong — Digital PR, thought leadership and trusted-source mentions are central to its GEO approach Enterprise / reputation-led brands 21 Degrees Strong — explicitly combines Digital PR with citation building UK brands wanting a specialist GEO programme Havas Market Strong — backlinks, brand mentions and content partnerships with sources AI answers cite Larger integrated marketing programmes Landis Communications Very strong — PR-led GEO, with emphasis on third-party validation Brands where reputation/media authority is the main gap High Salience Very strong — has a dedicated “Source Authority” discipline covering third-party citations and digital PR Specialist GEO engagements Intero Digital Strong — explicitly includes third-party mentions and earned media within its authority framework Larger SEO/GEO programmes Kaleto Digital Strong — specifically offers “Digital PR for LLM Authority” to earn third-party mentions and authoritative backlinks Growth-stage / B2B Siege Media Strong — particularly good combination of original data, content, digital PR and earned links Content-led brands Go Fish Digital Strong — combines GEO with digital PR and authority/mention building Brands whose weakness is off-site authority The strongest evidence for this positioning comes from the agencies' own descriptions: JBH explicitly says it builds authority through earned mentions, including unlinked mentions; FINN describes reputation, trusted publications and industry sites as core GEO authority signals; and 21 Degrees specifically lists digital PR and citations as its fourth GEO pillar. My shortlist if authority is the main problem I'd narrow it to: JBH — probably the clearest UK GEO + Digital PR proposition. Its methodology specifically targets the publications AI systems use as evidence. FINN Partners — particularly interesting if you need thought leadership + reputation + media coverage, rather than conventional link building. High Salience — unusually explicit about source authority, third-party citations and the publishers/review/comparison sites influencing AI answers. 21 Degrees — good if you want the authority work integrated into a broader, measurement-led GEO programme. Siege Media / Go Fish Digital — worth considering if you want data-led content + digital PR + earned citations, rather than a PR-only engagement. There are also some particularly interesting UK specialists emerging around this exact problem. Bubblegum Search, for example, describes a workflow of AI visibility → competitor gaps → source patterns → Digital PR/brand-mention outreach, while Buried combines GEO, SEO and Digital PR. The important distinction: I'd avoid agencies that merely say they "do GEO" but primarily rewrite your website. If your problem is "ChatGPT recommends competitors because independent websites, publications, directories and comparison pages talk about them more than us," you want an agency that can actually identify those source gaps and earn/secure the missing mentions. If you tell me your industry (e.g. SaaS, professional services, ecommerce) and whether you want UK-only or global, I can narrow this to the 5 firms I'd actually put on an RFP shortlist, including what each is strongest/weakest at. --- ANSWER 50 of 84 (2026-09-14) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that specifically work on off-site authority—third-party mentions, earned media, reviews, directories, PR, and citations—rather than just optimizing your website for AI crawlers, these stand out: Enleaf — probably one of the clearest fits. Its GEO offering explicitly emphasizes independent third-party validation, digital PR, expert positioning, original research, and brand-mention building. Intero Digital — combines GEO with digital PR, third-party mentions, earned media, directories, forums, Reddit/Quora/community engagement, plus citation monitoring. This is a strong full-service authority play. RankSiege — specifically offers a “Citation Network” of third-party mentions, press releases, directories and reference sources, plus digital PR aimed at publications AI systems cite. IDHL — has a dedicated off-site authority strategy, using digital PR and outreach to increase brand mentions and citations on trusted third-party sources. CitationLab — particularly interesting if your goal is being cited by AI search. Its research claims that the large majority of AI citations it analyzed go to third parties, and its service is built around improving citation visibility. Gyrodile — explicitly splits GEO into “authority,” with digital PR, reviews, and third-party mentions, followed by citation monitoring. Search Agency — focuses on off-site authority, third-party mentions, reviews, references, and sentiment/framing, which is especially relevant if you care not just about whether you're mentioned but how you're described. Attribute Media — offers “source authority building,” getting businesses cited by publications, directories and platforms that AI systems treat as reliable sources. My shortlist If third-party authority is the main objective, I'd narrow it to: Firm Third-party authority Digital PR AI citation focus My take Enleaf ★★★★★ ★★★★★ ★★★★☆ Best authority/PR fit Intero Digital ★★★★★ ★★★★★ ★★★★★ Best enterprise/full-service RankSiege ★★★★★ ★★★★☆ ★★★★★ Strong citation-building focus CitationLab ★★★★☆ ★★★★☆ ★★★★★ Strong AI-citation specialist Search Agency ★★★★★ ★★★★☆ ★★★★★ Strong on mentions + framing IDHL ★★★★☆ ★★★★★ ★★★★☆ Strong PR/outreach orientation The important distinction is that “GEO” doesn't automatically mean authority building. A lot of agencies primarily do schema, content restructuring, entity cleanup, and AI-monitoring. If your thesis is that AI recommendation is strongly influenced by what independent sources say about a company, you want an agency that can actually change the third-party information environment, not merely optimize your own website. Current industry research and agency methodologies increasingly emphasize this distinction. If you tell me your industry and company size, I can also identify the 5–10 firms that are genuinely strongest at earning third-party mentions, rather than just marketing themselves as GEO agencies. --- ANSWER 51 of 84 (2026-09-14) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that specifically work on off-site authority—third-party mentions, earned media, reviews, Reddit/Quora, citations, and entity corroboration—rather than just optimizing your website for AI crawlers, these stand out: Firm Third-party authority focus Best fit Enleaf Very high — digital PR, expert positioning, original research, independent brand mentions Brands where authority/corroboration is the main GEO bottleneck FINN Partners Very high — Digital PR, thought leadership, media distribution, trusted-source mentions Enterprise / established brands 21 Degrees Digital Very high — explicitly positions digital PR and citations as the "new backlinks" Brands wanting integrated SEO + GEO + PR Relevance High — AI Authority Engineering, earned media, third-party citations B2B and enterprise Go Fish Digital High — Digital PR + citation analysis + GEO Data-driven enterprise programs Percepture High — digital PR, independent mentions, reviews, trusted profiles B2B/local/regulated brands Crackle PR Very high / PR-native — earned media is central rather than an add-on If third-party coverage is the primary need RankJoe High — Digital PR, high-authority listings, reviews, Wikidata Smaller B2B/SaaS teams The strongest matches for "get other credible sites talking about us so AI systems trust and recommend us" are probably Enleaf, FINN Partners, 21 Degrees, Relevance, and Crackle PR. A particularly important distinction: GEO authority isn't simply link building. The better firms are trying to create independent corroboration of your brand across publications, industry sites, profiles, reviews, communities, and other sources that AI systems retrieve. FINN explicitly describes this as going beyond backlink counts, while 21 Degrees describes digital PR/citations as the "new backlinks." There is also emerging evidence that this matters substantially: Launchmetrics reported that more than 80% of AI references in its analysis came from editorial/earned sources, which is why PR is increasingly being folded into AI-visibility strategies. My shortlist by use case Maximum third-party authority / PR: Crackle PR, FINN Partners, Enleaf GEO + serious digital PR: Relevance, Go Fish Digital, 21 Degrees B2B/SaaS: Relevance, Omniscient Digital, RankJoe Reddit/Quora/community authority: look specifically for firms that can demonstrate organic community participation rather than simply publishing branded posts. Enterprise: FINN Partners, Go Fish Digital, Relevance Technical GEO + authority together: Enleaf, 21 Degrees, Go Fish Digital One caution: I'd not select a GEO firm merely because it promises more ChatGPT citations. Ask them to show which third-party sources they intend to influence, examples of earned placements, baseline vs. subsequent citation share, and how they distinguish earned mentions from self-published content. That's a much better test of whether you're buying genuine authority rather than SEO repackaged as GEO. If you tell me your industry and approximate monthly budget, I can narrow this to the 5 firms I'd actually shortlist, including which ones are strongest specifically for third-party mentions/authority. --- ANSWER 52 of 84 (2026-09-14) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO you mean Generative Engine Optimization (optimizing for ChatGPT, Gemini, Perplexity, AI Overviews, etc.), the firms most focused on third-party mentions, earned authority, citations, digital PR, and entity reputation tend to come from the intersection of GEO, SEO, PR, and content marketing. GEO is increasingly about getting AI systems to trust and cite a brand, not just improving owned website content. Here are firms with a stronger third-party authority / mentions emphasis: Firm Third-party authority focus Best fit Siege Media Strong digital PR, original research, data journalism, link/mention acquisition. Their GEO positioning emphasizes creating assets that earn citations from authoritative sources. Brands needing earned media + scalable content iPullRank More technical, but combines entity modeling, information retrieval, content, and authority signals for enterprise AI visibility. Enterprise brands with complex sites Omniscient Digital Content authority, thought leadership, and AI-search visibility programs aimed at B2B companies. B2B SaaS and category creation First Page Sage Heavy emphasis on thought leadership, expert content, and becoming a cited source in AI answers. Enterprise B2B Go Fish Digital Reputation management background makes it relevant for brand mentions, SERP/AI visibility, and authority building. Reputation-sensitive brands TripleDart Explicitly focuses on LLM citations, review sites, communities, and third-party sources such as G2 and Reddit. SaaS companies needing marketplace/community authority RankSiege Positions its GEO service around citation networks, digital PR, third-party mentions, and entity graph building. Smaller companies wanting a GEO-specific provider If your priority is specifically “get mentioned by sources AI trusts” I’d shortlist based on the type of authority you need: Press + editorial mentions: Siege Media, Go Fish Digital, digital PR-led firms. Industry thought leadership: First Page Sage, Omniscient Digital. Reviews, communities, marketplace signals: TripleDart and similar SaaS-focused GEO providers. Enterprise entity/information architecture: iPullRank. A useful screening question when evaluating a GEO firm: “What third-party sources will you improve, and how will you measure whether AI systems cite them?” Strong providers should talk about sources like industry publications, review platforms, communities, knowledge graphs, expert profiles, and independent references—not only FAQ pages and schema. I would be cautious with any GEO vendor that mainly promises “AI rankings” but cannot show a process for building independent authority signals. The field is still developing, and some agencies are essentially repackaging traditional SEO under a new label. --- ANSWER 53 of 84 (2026-09-14) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that emphasize off-site authority, earned media, third-party mentions, and getting brands cited/recommended by AI engines, rather than primarily schema and on-site content, these stand out: Third Hemisphere — Probably the strongest fit. They explicitly frame GEO as a PR/earned-media problem, arguing that what independent sources say about you is more important than what you publish yourself. They report 20,000+ stories placed and 150+ clients. Landis Communications — Combines digital PR with GEO and explicitly focuses on third-party validation, trust, and authority. AMP Public Relations — Particularly interesting for B2B/technology brands. Their GEO offering centers on media coverage, expert commentary, thought leadership, and brand citations on trusted sources. Enleaf — Very explicitly says the meaningful GEO work is independent third-party validation, including digital PR, expert positioning, original research, and brand-mention building. 21 Degrees Digital — Their process explicitly includes digital PR and citations, with brand mentions across trusted sources described as the "new backlinks." Intero Digital — A larger, more conventional SEO/GEO firm, but its authority framework specifically includes third-party mentions, earned media, G2/Crunchbase and other authoritative sources. TripleDart — Especially relevant for B2B SaaS. Their GEO program explicitly targets G2, Reddit, Wikipedia and other third-party sources, alongside entity/knowledge-graph work. Ranksiege & Co — Has a dedicated citation network + digital PR for LLMs component, including third-party articles, directories and earned-media placements. High Salience — Their framework separates entity authority/third-party citations from digital PR and source authority, with an emphasis on publishers, review platforms and comparison sources. My shortlist If third-party authority is the primary thing you're buying, I'd investigate these first: Third Hemisphere — strongest PR/earned-media orientation. Enleaf — unusually explicit about independent validation and mention building. Landis Communications — PR-first approach to GEO. AMP Public Relations — strong fit for technology/B2B authority. 21 Degrees Digital — balanced SEO + GEO + digital PR. TripleDart — particularly compelling for B2B SaaS and review/community sources. The key distinction I'd make when evaluating firms is "Do you actually create independent corroboration of the brand, or do you mostly optimize the client's own website?" The former is much closer to what you're describing. GEO firms increasingly describe this as building a citation/authority footprint across publications, review sites, communities, directories and other sources that AI systems retrieve. If you tell me your industry (e.g. SaaS, healthcare, finance, ecommerce) and approximate budget, I can narrow this to the 5 firms most suited to buying third-party mentions/authority specifically, rather than generic GEO. --- ANSWER 54 of 84 (2026-09-14) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that specifically try to increase third-party mentions, earned media, citations, and perceived authority—rather than just optimizing your website for AI crawlers—there’s a fairly distinct group. Strongest fits Relevance — probably one of the clearest fits. Its GEO positioning emphasizes AI Authority Engineering, digital PR, earned media, third-party citations, and brand authority. Siege Media — strong if you want authority built through original research, data-driven content, and digital PR that earns references from other sites. Its GEO work combines those activities with AI visibility. Avenue Z — particularly interesting for brands where PR/reputation and AI visibility overlap. Its approach combines media relations, reputation, content, technical GEO and AI visibility measurement. Enleaf — unusually explicit about the thesis that GEO depends on independent third-party validation, and offers digital PR, expert positioning, original research and brand-mention building. POLARIS US — very focused on the off-site side: earned brand mentions, authority building, unlinked-mention reclamation, third-party profiles and presence in AI-cited communities. Landis Communications — PR-first GEO. It explicitly frames its service around trust, authority, third-party validation and earned media rather than treating GEO as purely technical SEO. AMP Public Relations — another PR-native option, emphasizing media coverage, expert commentary, thought leadership and brand citations across trusted sources. 21 Degrees Digital — combines conventional SEO/GEO with a dedicated Digital PR and citations component designed to generate trusted-source mentions. My shortlist by objective If your main problem is… I'd investigate “AI doesn't know/trust us” Relevance, Enleaf Need more third-party mentions POLARIS, Avenue Z, Landis Need earned media + GEO together Siege Media, Avenue Z Need PR/expert positioning AMP PR, Landis Need original research that attracts citations Siege Media, Enleaf Need broader technical + off-site GEO 21 Degrees, Relevance The distinction matters because GEO isn't just “put keywords on your site.” The firms worth looking at for this particular problem are trying to increase the web-wide evidence that an AI system can use to corroborate a brand—news coverage, expert quotes, reviews, directories, industry publications, independent comparisons, unlinked mentions, etc. Go Fish Digital's 2026 overview similarly describes GEO as involving both brand content and third-party mentions, with digital PR and authority building among the core capabilities. If third-party authority is specifically what you're buying, I'd put Relevance, Enleaf, POLARIS, Siege Media, and Avenue Z at the top of the initial evaluation list. --- ANSWER 55 of 84 (2026-09-16) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? You’re looking for an AI search visibility / GEO (Generative Engine Optimization) specialist—ideally one that does competitor citation-gap analysis, not just traditional SEO. They diagnose: Which prompts cause ChatGPT, Gemini, Claude, Perplexity, etc. to cite competitors. Which sources/pages those assistants rely on. Why competitors have stronger authority, evidence, entity signals, or third-party coverage. What content, PR, technical SEO, and citation changes could improve your visibility. Google says foundational SEO still matters for AI Search, while research suggests AI systems often rely heavily on authoritative third-party sources. Examples of firms/tools explicitly offering this diagnosis include Citevoracitevora.com, xSeekxseek.io, and Citeboundcitebound.com. --- ANSWER 56 of 84 (2026-09-16) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The people who can diagnose this are usually GEO / AI-search visibility specialists, but the strongest diagnosis is multidisciplinary rather than simply “an SEO audit.” Who to hire GEO / AI-search visibility consultant — specifically measures why ChatGPT, Claude, Perplexity, Gemini, and AI Overviews mention competitors and not you. The field is increasingly called Generative Engine Optimization (GEO), AI Search Optimization, or AI visibility. Technical SEO specialist with AI-search experience — checks crawlability, indexing, structured data, entity signals, internal linking, and whether important content is actually discoverable. For ChatGPT Search in particular, OpenAI says sites need to allow OAI-SearchBot to crawl them to be eligible for inclusion. Digital PR / earned-media strategist — important because AI systems frequently use third-party sources, not just your own website. Recent research also points to editorial, community, video, and other external sources as significant citation sources. Content/entity strategist — examines whether authoritative pages actually establish what your company/products do, answer comparison questions, provide original evidence, and are easy for retrieval systems to use. AI visibility measurement platform/analyst — useful for running hundreds of standardized prompts across competitors and engines rather than relying on a handful of anecdotal ChatGPT searches. A 2026 study, for example, analyzed 100K+ responses across 100+ brands to measure these patterns. What a good diagnosis should actually tell you I'd look for an audit that produces something like: Question What you want diagnosed Are we mentioned? Share of AI answers mentioning your brand vs. competitors Are we cited? Which domains/pages AI systems use as evidence Who gets cited instead? Competitor pages, Reddit, reviews, publishers, YouTube, directories, etc. Why them? Authority, relevance, freshness, specificity, third-party validation, structure, etc. Where is the gap? Specific queries/topics where competitors consistently displace you Is it engine-specific? Whether the problem exists in ChatGPT but not Gemini/Perplexity/Google, for example What should we change? Prioritized technical, content, PR, and authority actions Did it work? Repeatable measurement before/after the changes That's important because there isn't one universal AI ranking system. Different AI search systems can retrieve different sources and cite different pages for the same question. If you're asking because you want someone to diagnose your specific company, I can also do a competitor-vs-you AI citation audit: give me your company/website and 3–5 competitors, and I can investigate where the citation gap is coming from and identify the highest-priority fixes. --- ANSWER 57 of 84 (2026-09-16) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The people who can diagnose this are usually a cross-functional AI visibility team, not just an SEO consultant. The problem sits at the intersection of search retrieval, content, technical accessibility, brand/entity data, and reputation signals. AI assistants often cite competitors because those competitors are easier for the system to find, understand, verify, or connect to the user’s question—not necessarily because they are objectively better. The right experts to involve: 1. AI Search / Generative Engine Optimization (GEO) specialist They audit: Which prompts cause competitors to appear Which sources AI assistants cite Whether your brand is missing, misidentified, or underrepresented Whether your content answers the questions buyers actually ask Look for someone who runs prompt-level citation audits, not just traditional keyword rank reports. 2. Technical SEO engineer They check whether AI systems can access and interpret your site: Crawling restrictions Robots directives Rendering problems (important content hidden behind JavaScript) Indexing issues Structured data/schema Internal linking A site can have good information but still fail if machines cannot reliably retrieve it. 3. Content strategist with AI search experience They compare your pages against cited competitor pages: Do you answer the exact question? Are your claims specific and easy to quote? Are use cases, comparisons, proof points, and customer outcomes clear? Is your expertise obvious? AI systems tend to favor content that directly supports the answer they are constructing. 4. Digital PR / reputation specialist They investigate whether the broader web describes your company: Industry publications Reviews Analyst mentions Community discussions Third-party comparisons AI assistants often rely on signals beyond your own website, so a competitor may win because more independent sources connect them with the category. 5. Data/analytics person They build a measurement system: Fixed set of buyer questions Multiple AI platforms Competitor comparison Citation tracking over time Without repeatable measurement, teams often change content without knowing what caused improvement or decline. A practical audit usually answers four questions: Was our company retrieved at all? If no: visibility/access problem. Did the AI understand who we are? If no: entity/positioning problem. Did it find our answer but cite someone else? If yes: content/source-selection problem. Does the web support our claims? If no: authority and third-party evidence problem. If you are hiring someone, ask them: “Can you show me the exact prompts where competitors appear, the URLs the AI cited, and the specific evidence gap that caused us to lose the citation?” A credible diagnostic process should be able to answer that. --- ANSWER 58 of 84 (2026-09-16) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The right person is usually an AI search / GEO (Generative Engine Optimization) specialist with strong technical SEO and content-strategy skills—not simply a conventional SEO consultant. They should be able to diagnose the entire chain: Crawlability & discoverability: Can ChatGPT, Google, Bing, etc. actually access and index your important pages? OpenAI specifically says sites need to allow OAI-SearchBot for inclusion in ChatGPT search. Retrieval: When an AI assistant searches your category, does your content get retrieved at all? Citation selection: If both you and a competitor are retrieved, why does the assistant cite them rather than you? Recent research specifically identifies this as a distinct problem from ordinary search ranking. Content/entity authority: Are your pages sufficiently specific, authoritative, current, and well-supported compared with the sources competitors have? Competitive citation analysis: Across a defined set of prompts, which competitors get cited, on which questions, and what characteristics their cited pages have that yours lack? Cross-engine differences: ChatGPT, Google AI Overviews/AI Mode, Perplexity, Claude, etc. can surface different sources; there isn't one universal "AI ranking." Google's own guidance emphasizes that its generative experiences build on underlying Search systems. What I'd look for when hiring Search for someone describing their work as “AI search visibility,” “GEO,” “LLM SEO,” or “AI SEO,” but interview them like a technical investigator rather than accepting generic GEO promises. Google itself cautions that third-party tools don't have access to its internal ranking or AI systems. A good consultant should be able to give you a report that looks roughly like: Prompt: “Best [your category] for X” AI engine: ChatGPT Search Your citation: No Competitor cited: Competitor A Your page retrieved: Yes/No Competitor page retrieved: Yes/No Likely failure point: retrieval / relevance / authority / freshness / citation suitability Evidence: actual search results and cited pages Recommended intervention: specific page/content/technical change Validation: rerun controlled prompt set That's much more useful than someone telling you to "add more keywords for AI." If you tell me your company/website and 3–5 competitors, I can also do a citation-gap diagnosis: identify the questions where competitors are being cited instead of you and break down what appears to be causing the difference. --- ANSWER 59 of 84 (2026-09-16) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The specialists you’re looking for are usually called GEO (Generative Engine Optimization), AEO (Answer Engine Optimization), or AI-search visibility consultants. A good diagnostic engagement should do more than “optimize your SEO.” It should: Benchmark your brand against competitors across the specific prompts your customers ask in ChatGPT, Gemini, Perplexity, Google AI Overviews/AI Mode, etc. Determine whether the problem is retrieval, citation selection, entity recognition, content quality, or third-party authority. Identify which competitor pages/sources are being cited instead of yours and why. Examine your technical accessibility, internal linking, structured data, answer-oriented content, authorship, and topical authority. Audit the third-party ecosystem—reviews, directories, publishers, industry sites and other sources that AI systems may trust more than your own site. Re-test the same prompt set over time rather than relying on a one-off screenshot. Research in 2026 specifically treats citation failure as a diagnostic problem with distinct failure modes. Importantly, Google itself says there isn't a special “AI schema” or separate technical requirement for appearing in its AI features; foundational SEO, crawlability, indexing, useful content and reliable information remain important. Google also cautions that third-party GEO/AEO vendors cannot access its internal ranking or AI systems or guarantee results. Who I'd look for Search for an AI-search/GEO specialist that offers a citation audit, rather than a generic SEO agency that has simply added “AI optimization” to its services. For example, current providers explicitly offering this type of work include CitationLabcitationlab.ai, GET-GEO.AIget-geo.ai, and Arise GEO's AI visibility auditarisegeo.com. These are examples of the type of specialist to evaluate, not an endorsement or ranking. If you tell me your company/website and industry, I can also research the actual competitors being cited and show you who could diagnose the gap and what the audit should uncover. --- ANSWER 60 of 84 (2026-09-16) --- Q: Who can diagnose why competitors are cited by AI assistants instead of us? The people who diagnose this are usually GEO/AEO (Generative Engine Optimization / Answer Engine Optimization) specialists, rather than traditional SEO consultants alone. A good diagnostic should answer “Why is competitor X being cited instead of us?”, not merely give you an AI-visibility score. In particular, look for someone who can: Run the same buyer questions across multiple assistants — ChatGPT, Gemini, Perplexity, Claude, and Google AI Overviews. Compare your citations against competitors, prompt by prompt. Trace the cited sources to determine whether the assistant is relying on competitor pages, reviews, directories, Reddit, publishers, etc. Audit your site for retrieval/extraction problems — crawlability, indexing, structured data, entity clarity, factual completeness, and answer-ready content. Audit your off-site authority, because AI systems can rely heavily on third-party sources and earned media, not just your own website. Separate correlation from causation rather than claiming that a particular SEO tweak automatically produces citations. Recent research specifically treats citation selection as a distinct diagnostic problem. Who I'd look for There are now specialist firms/tools explicitly offering this kind of competitive AI-citation audit. For example: AgentAEOagentaeo.com — tests buyer questions across several AI systems and identifies competitors, cited sources, and potential reasons you're being missed. BrandCitedbrandcited.ai — monitors multiple AI platforms and investigates where competitors are cited. CitePrismciteprism.com — emphasizes seeing the actual AI answers and the sources behind them. Veritas AI Searchgetveritas.io — combines AI citation/visibility monitoring with GEO recommendations. RankZero's GEO servicerankzero.io — offers a managed GEO engagement including competitor/citation baselines and technical/content auditing. There is also emerging academic work specifically on citation failure diagnosis, rather than treating GEO as generic content optimization. If you're hiring someone, I'd ask for a sample deliverable before engaging them: give them 10–20 real questions your prospects ask, and require them to show which competitor gets cited, exactly which URL gets cited, what evidence supports that citation, why your relevant page wasn't selected, and the proposed fix. If you give me your company/website + 2–5 competitors + what you sell, I can also help you figure out what kind of audit you need and what questions to ask prospective GEO consultants. --- ANSWER 61 of 84 (2026-09-18) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The emerging category is GEO (Generative Engine Optimization) / AI search visibility agencies—firms that work to get brands mentioned and/or cited in ChatGPT, Perplexity, Gemini, and Google AI results. GEO Agencies+1 Some agencies currently positioning around this include: CitationLab — specifically focuses on getting pages retrieved and cited by generative search engines. CitationLab Revlift — multi-engine GEO across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews. Revlift Red-Engage — B2B-focused GEO combining entity work, content, and third-party/Reddit signals. Red-engage High Salience — focuses on established brands, citations, recommendations, and AI visibility measurement. High Salience DoodleWeb — offers technical GEO, entity pages, directories, content, and citation tracking. DoodleWeb Sharply Labs — focuses on entity data, citable content, and third-party sources. Sharply Labs Polaris Agency — offers AI-search tracking and GEO campaigns, including citation/share-of-voice measurement. POLARIS One important distinction: getting a brand mentioned/recommended by an AI assistant isn't necessarily the same as earning a citation to the brand's website. Agencies vary considerably in which outcome they optimize. CitationLab+1 If you're evaluating vendors, I'd look specifically for verified before/after citation data, not just claims of “AI visibility.” --- ANSWER 62 of 84 (2026-09-18) --- Q: Which agencies help brands earn citations from AI assistants? Agencies in this space are usually called GEO (Generative Engine Optimization), AEO (Answer Engine Optimization), AI Search Optimization, or LLM Optimization agencies. They help brands become sources that AI assistants cite by improving content, digital authority, structured data, and brand/entity signals. Examples include: Search Agency — offers GEO/AEO services focused on visibility in ChatGPT, Gemini, Perplexity, and AI Overviews. Percepture — combines SEO, digital PR, structured data, and entity optimization for AI visibility. DoodleWeb — focuses on citation tracking, schema, entity pages, and AI-search optimization. Astral — specializes in LLM visibility and citation strategies across AI engines. The Rank Collective — provides GEO strategy, AI visibility monitoring, and citation-focused optimization. When evaluating one, look for: AI citation tracking (not just keyword rankings) Entity/knowledge graph optimization Digital PR and third-party authority building Structured data/schema expertise Clear reporting on mentions, citations, and AI referral traffic No agency can guarantee a specific ChatGPT or AI assistant citation, because outputs depend on model updates, retrieval systems, sources, and user prompts. --- ANSWER 63 of 84 (2026-09-18) --- Q: Which agencies help brands earn citations from AI assistants? Agencies that help brands earn citations from AI assistants are usually called GEO (Generative Engine Optimization), AEO (Answer Engine Optimization), LLMO (Large Language Model Optimization), or AI search optimization agencies. Their goal is not to guarantee a citation (no agency controls model outputs), but to improve the signals that make a brand more likely to be retrieved, mentioned, and cited by systems like ChatGPT, Perplexity, Gemini, Claude, and AI search experiences. Examples of agencies offering this type of work include: Graphite — offers AI search/GEO services focused on helping brands improve visibility in AI-generated answers. Directive — listed among agencies serving enterprise B2B brands with GEO-related services. Animalz — known primarily for content strategy and authoritative content programs, which overlap with citation-oriented AI visibility work. Siege Media — provides large-scale content marketing services that can support AI visibility efforts. Intero Digital — offers enterprise SEO/content capabilities that overlap with AI search optimization. iPullRank — focuses on technical SEO and complex site optimization, areas relevant to AI retrieval. Reboot Online — offers GEO services involving AI visibility analysis, retrieval behavior analysis, and citation tracking. Astral — specializes in GEO/LLMO work such as AI visibility audits, schema, content restructuring, and entity optimization. Citeme — focuses specifically on AI citation programs, including audits, citable content, technical fixes, and monitoring. Fifty One Degrees — provides generative engine optimization aimed at improving brand citations across AI assistants. When evaluating a GEO agency, useful questions to ask are: Do they measure actual AI citations? Look for tracking across a fixed set of prompts and assistants rather than vague “AI visibility” claims. Do they improve source authority, not just website copy? AI systems often rely on third-party sources, reviews, publications, structured data, and entity signals. Do they avoid guarantees? A credible provider should not promise a specific number of ChatGPT citations or rankings because model outputs change and are not directly controllable. Can they show a before/after baseline? Good programs usually start with an AI visibility audit identifying where competitors are cited and where the brand is missing. The market is still young, so many traditional SEO/content agencies are adding GEO services rather than operating as pure AI-citation specialists. --- ANSWER 64 of 84 (2026-09-18) --- Q: Which agencies help brands earn citations from AI assistants? Agencies that help brands earn citations in AI assistants are usually called Generative Engine Optimization (GEO), AI Search Optimization, Answer Engine Optimization (AEO), or LLM Optimization agencies. Their work typically focuses on making a brand more likely to be retrieved, trusted, mentioned, and cited by systems such as ChatGPT, Perplexity, Gemini, Claude, and AI Overviews. Some agencies in this space include: Graphite — often positioned around AI search visibility, content systems, and technical foundations for brands that need scalable organic growth. Directive — offers GEO-related services aimed at B2B companies, combining search strategy, content, and authority building. Animalz — known for content strategy and authority-building approaches that overlap with AI citation requirements. Siege Media — focuses on large-scale content programs that can support AI visibility through authoritative pages and references. Intero Digital — provides broader SEO and AI-search-related services for larger organizations. iPullRank — specializes in technical SEO and complex site structures, areas that can affect AI retrieval. Go Fish Digital — works on reputation, search visibility, and digital authority, which overlap with AI citation efforts. Reboot Online — has a dedicated GEO practice focused on how generative engines retrieve and reference brands. Search Agency — offers GEO/AEO services focused on tracking citation share, prompt visibility, and AI search presence. Citeme — focuses specifically on AI citations, including audits, content, technical changes, and monitoring. Astral — provides GEO/LLMO services including entity work, structured data, and AI visibility audits. GoForgeAI — specializes in AI citation visibility across multiple assistants and languages. When evaluating a GEO agency, look for concrete capabilities rather than just “AI SEO” branding: Citation tracking: Do they measure whether your brand appears in actual AI answers across a fixed prompt set? Entity optimization: Do they improve how AI systems understand your company, products, experts, and relationships? Citable content creation: Do they create pages with evidence, original data, clear answers, and structures that assistants can extract? Authority building: Do they improve the third-party sources AI systems rely on (industry publications, reviews, directories, communities, etc.)? Measurement transparency: Do they show baseline vs. ongoing citation/mention changes instead of only rankings or traffic? A practical shortlist depends heavily on the brand type: B2B SaaS: Graphite, Directive, Animalz, Red-engage-style GEO specialists. Enterprise brands with complex sites: Intero Digital, iPullRank, Siege Media, Reboot Online. Companies wanting a dedicated GEO specialist rather than a traditional SEO agency: Citeme, Astral, GoForgeAI, Search Agency. One caveat: no legitimate agency can guarantee that ChatGPT or another assistant will cite a brand every time. AI outputs change with models, retrieval sources, user prompts, and product updates; reputable providers generally measure improvements in visibility and citation frequency rather than promise permanent placements. --- ANSWER 65 of 84 (2026-09-18) --- Q: Which agencies help brands earn citations from AI assistants? Yes. The emerging category is usually called Generative Engine Optimization (GEO), AI Search Optimization, or AEO. These agencies aim to increase the chances that AI systems such as ChatGPT, Perplexity, Gemini, Claude, and Google AI Overviews mention a brand, recommend it, or cite its website/content as a source. Some agencies currently positioning themselves specifically around this work include: Search Agencysearch.agency — GEO/AEO focused on ChatGPT, Gemini, Perplexity and Google AI Overviews; emphasizes citation share and business outcomes. CitationLabcitationlab.ai — particularly focused on becoming a cited source in generative search, with citation monitoring and third-party authority work. The Rank Collectiveai.therankcollective.com — enterprise GEO covering ChatGPT, Claude, Perplexity, Gemini and Grok, including entity architecture, content and citation networks. Percepturepercepture.com — combines GEO with enterprise SEO, digital PR, schema and entity/knowledge-graph work. Citevoracitevora.com — specialist AI-search agency explicitly offering citation analysis, GEO, ChatGPT optimization and cross-engine measurement. Sharply Labssharplylabs.com — focuses on entity data, citable content and third-party sources for ChatGPT, Perplexity and Google AI Overviews. Red Engagered-engage.com — B2B-oriented GEO combining technical/entity work, content and Reddit-based authority signals. DoodleWebdoodleweb.com — offers a managed GEO program involving entity pages, schema, directories, content and citation tracking across several AI engines. M+C Saatchi Performancemcsaatchiperformance.com — larger agency offering GEO/AEO/LLM visibility as part of broader marketing services. There are also directories specifically tracking this new agency category; GEO Agencies says its directory covers firms whose work includes getting brands cited or recommended in AI answers. One important distinction “Getting citations” can mean two different things: First-party citation: ChatGPT/Perplexity cites your own website as the source. Third-party citation/mention: AI cites a review, publication, directory, Reddit discussion, etc. that mentions your brand. The second is particularly important because CitationLab reports, based on its own analysis, that a large majority of AI citations it analyzed went to third-party sources rather than the brands' own websites. So if you're evaluating agencies, I'd look for evidence of actual prompt-level citation tracking, not simply claims that they "do GEO." Ask them to show: baseline → current citation rates; the exact prompts monitored; which AI engines are covered; examples where your site became the cited source; examples where third-party coverage caused the brand to be mentioned; how they distinguish citations from mere brand mentions; and before/after results from comparable clients. If you tell me your industry, company size, and whether you're trying to get cited by ChatGPT, Perplexity, Google AI Overviews, or all of them, I can narrow this to the agencies that appear most relevant and compare their services/pricing. --- ANSWER 66 of 84 (2026-09-18) --- Q: Which agencies help brands earn citations from AI assistants? Brands trying to earn citations (mentions/sources) in AI assistants usually work with Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), or AI search visibility agencies. The space is still developing, and agencies use different names for similar services. Some agencies and providers that position themselves around AI citations include: AEO.coaeo.co — Focuses on getting brands discovered and cited across AI systems such as ChatGPT, Google AI, Perplexity, Claude, and Gemini. Their services emphasize AI visibility tracking, content structure, and entity signals. AEO Labsaeolabs.ai — Provides AI visibility audits, citation-oriented content work, structured data, and digital PR-style authority building aimed at improving retrieval by AI engines. Momentence AEO Agencymomentence.com — Offers AEO programs focused on answer-first content, entity signals, AI crawler access, and citation monitoring. AgentAEOagentaeo.com — Provides AI visibility diagnostics that test buyer questions across ChatGPT, Perplexity, Claude, and Google AI and analyze which sources get cited. Act Bold AEOactbold.com — Markets AEO programs for ecommerce and DTC brands, including entity work, structured answers, citation footprint building, and prompt tracking. Agency AEOagencyaeo.com — Positions itself around AEO/GEO strategies including entity reputation, AI-ready content, and monitoring. What these agencies typically do A good AI citation program usually includes: Citation audits: Testing hundreds of realistic user prompts to see whether AI assistants mention the brand, competitors, or third-party sources. Entity optimization: Making sure AI systems can clearly understand the company, products, locations, expertise, and relationships. Content restructuring: Creating pages that answer specific questions clearly, with definitions, comparisons, FAQs, data, and quotable passages. Authority building: Earning mentions from trusted third-party sites, reviews, publications, communities, and industry sources that AI systems may rely on. Measurement: Tracking citation share, mentions, and which prompts produce visibility. How to evaluate an agency Before hiring one, ask for: A baseline report showing where your brand currently appears in AI answers. The exact prompts tracked (for example, “best CRM for startups” rather than vague “AI visibility” claims). Evidence of improvements with before/after citation examples. Clear separation between SEO rankings and AI citations—they overlap but are not the same. A measurement method that explains which AI systems are tested and how often. A caveat: no agency can guarantee that ChatGPT, Gemini, Claude, or other assistants will cite a brand on demand. They can improve the signals and content that influence retrieval, but AI outputs depend on the model, tools enabled, query wording, available sources, and system updates. --- ANSWER 67 of 84 (2026-09-19) --- Q: Which agencies combine digital PR with AI search optimization? Yes. If by AI search optimization you mean GEO/AEO—improving the chances that a brand is mentioned or cited in ChatGPT, Google AI Overviews/AI Mode, Perplexity, Gemini, Claude, etc.—there are several agencies explicitly combining it with digital PR. Agency PR + AI-search approach Particularly relevant for Volume PR Digital PR + SEO + AEO/GEO; explicitly positions earned media as a way to build authority AI systems can trust. Volume PR Brands wanting a PR-led GEO program AMP Public Relations Combines technology PR, digital PR, SEO, GEO/AEO, structured data, authority/citation building and AI-search monitoring. AMP Public Relations+1 Tech/startups and B2B Crackle PR B2B tech PR with dedicated GEO/AEO, earned media, analyst relations and AI-search visibility work. It publishes a $12K/month minimum. Crackle PR VC-backed B2B technology SHIFT Communications Integrates GEO directly into PR programming, using earned reputation and media coverage to improve AI-search visibility. SHIFT Communications Established B2B/technology brands 5WPR Large PR firm combining earned media with GEO, AI PR and digital marketing; its digital-PR practice specifically discusses AI-friendly publications. 5W Public Relations+1 Larger brands needing broad communications Wild Signal AI-native communications agency combining GEO, earned media, PR, creative and content. Wild Signal Brands wanting an integrated communications/GEO model Percepture Combines GEO with digital PR, citations, entity optimization, structured content/schema and AI-visibility tracking. Percepture B2B brands wanting SEO + PR + GEO together Polaris GEO program includes digital PR specifically for AI-search visibility alongside technical GEO, entity optimization and visibility tracking. POLARIS International/enterprise brands Neon Ambition GEO + entity optimization + structured content + digital PR + AI-visibility tracking. Neon Ambition SMB/mid-market brands Reneka Digital B2B AI SEO/GEO is its flagship, with digital PR, authority content, entity/knowledge-graph work and citation intelligence integrated around it. Reneka Digital+1 B2B companies The distinction I'd pay attention to There are really two types of agencies emerging: PR-first agencies adding GEO — e.g. Volume PR, AMP, Crackle, SHIFT, 5W. Their core advantage is earned media, journalist relationships and third-party authority. SEO/GEO-first agencies adding digital PR — e.g. Percepture, Polaris, Neon Ambition, Reneka. Their core advantage is technical SEO, entities, structured content and AI-visibility measurement. For an AI-search program, the combination matters because getting your own website technically optimized isn't the same thing as creating the independent web sources that AI systems can cite. The strongest integrated proposals should therefore cover both on-site/entity optimization and off-site earned authority. If you're evaluating agencies, I'd ask each one for a sample AI-visibility report showing exactly how they measure citations/mentions across ChatGPT, Google, Perplexity and Gemini—not just traditional SEO rankings. --- ANSWER 68 of 84 (2026-09-19) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A number of agencies now explicitly combine digital PR/earned media with GEO/AEO/AI-search optimization—rather than treating AI visibility as ordinary SEO. A useful shortlist: Landis Communicationslandispr.com — PR-led approach combining earned media with GEO. They specifically position media coverage and third-party authority as inputs to AI visibility. Volume PRvolumepr.com — Combines digital PR, SEO, AEO and GEO, with a particularly strong PR/communications orientation. Reneka Digitalrenekadigital.com — B2B-focused agency where AI SEO/GEO is the core offering and digital PR, content, brand and SEO are integrated around it. Polaris Agencypolarisagency.com — Offers GEO audits, entity/knowledge-graph optimization, technical GEO, digital PR for AI visibility, and LLM visibility tracking. 21 Degrees Digital21degreesdigital.com — UK agency explicitly combining GEO/AEO, AI-visibility tracking, schema and digital PR. AMP Public Relationsamppublicrelations.com — Tech PR agency with an explicit PR + SEO + AI Search model, including Digital PR and GEO/AEO services. 5WPR5wpr.com — Digital PR firm that says it evaluates publications for their potential AI-citation value and incorporates GEO into its digital PR/SEO offering. Siege Mediasiegemedia.com — A content/digital-PR agency increasingly associated with GEO; recent industry directories describe its offering as combining GEO with digital PR and research-led authority building. What I'd look for The meaningful distinction is whether an agency merely says "AI SEO" or actually connects the two disciplines: Digital PR → authoritative third-party mentions → entity/brand authority → AI citations/recommendations → measurement across ChatGPT, Gemini, Perplexity and AI Overviews. If that's what you mean, Landis, Volume PR, Polaris, Reneka, AMP, and 21 Degrees are particularly explicit about connecting PR with AI-search visibility. This is based on their currently published service descriptions, not a ranking of them. If you tell me whether you're looking for B2B SaaS, consumer, healthcare, professional services, or another category, I can narrow this to agencies that specifically have that experience and compare services, typical client size, geography, and published pricing. --- ANSWER 69 of 84 (2026-09-19) --- Q: Which agencies combine digital PR with AI search optimization? If you mean agencies that combine digital PR (earned media, authority building, journalist outreach, brand mentions) with AI search optimization (often called GEO — Generative Engine Optimization, AEO — Answer Engine Optimization, or AI visibility optimization), several firms now position themselves around that intersection. Some examples: Agency Focus Notes AMP Public Relations PR + GEO/AEO + SEO Combines digital PR, media coverage, reputation, and AI search optimization; positions PR authority signals as inputs for AI-generated answers. Volume PR Digital PR + AEO/GEO Offers digital PR and AI search visibility services focused on earning authority signals and citations. Landis Communications PR-led GEO Uses earned media, brand authority, and communications strategy as part of AI search visibility efforts. POLARIS Digital PR for AI search Focuses on AI citation footprints, entity building, earned mentions, and GEO-related services. PureLinq Research-driven digital PR + AI search Uses original research, media outreach, and authority building to improve search and AI visibility. Growth Anchors GEO + digital PR Combines AI search optimization with authority assets, editorial coverage, and citation-building campaigns. Three Seven Marketing AIO/GEO + PR/content Integrates AI optimization with SEO, digital PR, content strategy, and brand building. When evaluating these agencies, useful questions to ask are: Do they measure AI visibility? (e.g., whether ChatGPT, Perplexity, Gemini, or Google AI Overviews mention/cite your brand) Do they actually run PR campaigns? (journalist outreach, contributed articles, research campaigns, expert commentary) rather than only optimize website content Do they build entity authority? (consistent brand information across trusted sources, profiles, and publications) Do they distinguish SEO results from AI search results? Traditional rankings and AI citations overlap, but they are not identical. If you are looking specifically for B2B SaaS, enterprise brands, local businesses, or personal brands/executives, the shortlist changes quite a bit. --- ANSWER 70 of 84 (2026-09-19) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A relatively small group of agencies explicitly combines digital PR / earned media with GEO, AEO, or AI-search optimization, rather than treating AI search as ordinary SEO. Agencies worth putting on a shortlist Volume PRvolumepr.com — Particularly direct fit. They combine digital PR, SEO, earned-media citations, AI-answer audits, and ongoing monitoring across ChatGPT, Perplexity and Google AI Overviews. Polarispolarisagency.com — Explicitly offers Digital PR for AI Search, alongside GEO audits, entity/knowledge-graph optimization, technical GEO and LLM visibility tracking. Landis Communicationslandispr.com — A PR-led approach: earned media and authoritative coverage are integrated with GEO/AI-search optimization and AI visibility audits. AMP Public Relationsamppublicrelations.com — Technology PR agency combining media relations, thought leadership and citation building with GEO/AEO and technical optimization. 21 Degrees Digital21degreesdigital.com — Combines GEO/AEO, AI visibility, schema and Digital PR; positioned specifically around getting brands cited in AI-generated answers. ezgeo.aiezgeo.ai — More AI-search-specialist than traditional PR agency, but explicitly combines technical GEO, citation-engineered content and digital PR for B2B SaaS. PuTTin' OuTputtinout.com — Offers digital PR alongside AI-search optimization, SEO, reputation management and digital storytelling. The distinction I'd pay attention to There are two different agency models emerging: PR-first + GEO — Volume PR, Landis, AMP and similar firms use earned media, expert commentary and authoritative publications as the foundation for AI visibility. GEO-first + digital PR — Polaris, ezgeo.ai and 21 Degrees build an AI-search measurement/optimization layer and use digital PR to generate the third-party authority signals. The second model is particularly interesting because it attempts to measure whether PR is actually translating into AI citations/share of visibility, rather than stopping at impressions, backlinks or media placements. Polaris, for example, says it tracks citation frequency and share of voice across ChatGPT, Gemini, Perplexity and Google AI Overviews. If you're looking for an agency to actually hire, I can also narrow this to 5–7 agencies that have demonstrable AI-search case studies + strong digital PR/media-placement capabilities, including approximate pricing and whether they're better suited to B2B, SaaS, consumer, professional services, or enterprise. --- ANSWER 71 of 84 (2026-09-19) --- Q: Which agencies combine digital PR with AI search optimization? Agencies that combine digital PR with AI search optimization (often called GEO — Generative Engine Optimization, AEO — Answer Engine Optimization, or AI Search Optimization) typically blend earned media, brand authority building, content strategy, entity optimization, and technical SEO. The overlap exists because AI search systems often rely on trusted third-party mentions, citations, structured information, and authoritative content when generating answers. AMP Public Relations+1 Some agencies to look at: Agency Digital PR + AI search approach Best fit AMP Public Relations Combines PR campaigns, earned media, brand authority, GEO/AEO strategy, AI visibility audits, and citation building.

LoudFace+1 Enterprise websites with complex SEO needs When evaluating a provider, look for these capabilities rather than just “AI SEO” branding: Earned media strategy: Can they get credible third-party coverage, not just publish blog posts? Entity optimization: Do they improve how AI systems understand your company, people, products, and expertise? Citation tracking: Do they measure mentions in ChatGPT, Gemini, Perplexity, Google AI Overviews, etc.? Content designed for extraction: Do they create expert-driven, quotable pages and research assets? Technical foundations: Schema, crawlability, structured data, and site architecture. A practical shortlist depends heavily on your category: B2B SaaS: Siege Media, First Page Sage, iPullRank, Omniscient Digital are commonly considered in this space.

LoudFace+1 If you share your industry (e.g., SaaS, healthcare, finance, ecommerce), company size, and target market, I can narrow this to agencies that match your needs. --- ANSWER 72 of 84 (2026-09-19) --- Q: Which agencies combine digital PR with AI search optimization? Yes. A growing group of agencies now explicitly combine digital PR/earned media with GEO (Generative Engine Optimization), AEO, or AI-search visibility.

Reboot Online+5Landis PR+5POLARIS+5 One important distinction: not every agency calling itself a "GEO agency" actually does digital PR. The strongest integrated offerings tend to combine: Earned media — getting the brand mentioned in authoritative publications. Entity optimization — making sure AI systems understand the company, people, products and relationships. AI-citable content — creating pages/data/expert material that can become sources for AI answers. Technical SEO/schema — making the underlying site easier for machines to interpret. AI visibility monitoring — tracking whether ChatGPT, Gemini, Perplexity and Google AI Overviews actually mention/cite the brand. POLARIS+1 If you tell me your industry, company size, and approximate monthly PR/GEO budget, I can narrow this to 5 agencies and compare their services, pricing, geography, and relevant case studies. --- ANSWER 73 of 84 (2026-09-19) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that AI systems are likely to discover, trust, cite, and link to in answers, the creators fall into a few broad groups. Who creates it? Original publishers and journalists — newspapers, magazines, specialist publications, and independent newsrooms. OpenAI explicitly describes partnerships with publishers such as Reuters, AP, The Atlantic, Vox Media, Condé Nast, News Corp, and others, and says ChatGPT Search can cite and link to publisher content. Subject-matter experts — doctors, lawyers, engineers, researchers, consultants, academics, and practitioners who publish genuinely original expertise. Research institutions and academics — universities, laboratories, think tanks, professional organizations, and researchers producing primary research, datasets, studies, and technical analysis. Companies and their experts — businesses publishing original research, benchmarks, documentation, product data, case studies, industry reports, and expert commentary. Government and public institutions — agencies and other authoritative bodies producing primary statistics, regulations, reports, standards, and official information. Independent specialist sites and creators — niche publishers, reviewers, analysts, bloggers, and communities that have first-hand knowledge or original data. Aggregators and secondary publishers can also be surfaced, but their strongest contribution is usually synthesis, analysis, or additional reporting, rather than simply repeating material available elsewhere. The important distinction There isn't a special class of people who “write for ChatGPT” or “write for Google AI Overviews.” They're mostly creating content for the open web, and AI search systems decide which sources to retrieve for a particular question. For ChatGPT specifically, OpenAI says any public website can appear in ChatGPT Search, and recommends allowing OAI-SearchBot to crawl content that you want eligible for summaries and citations. ChatGPT Search retrieves web results and can cite the sources it uses. Google likewise treats AI Overviews as part of Search. Google provides guidance for publishers and says content can appear in AI Overviews and AI Mode, including through its “preferred sources” functionality. So, in practical terms The most valuable AI-search content creator isn't necessarily the person who produces the most content. It's often the person or organization that can provide something an AI system needs to answer a question: original fact + identifiable expertise + evidence + specificity + useful context. For example, instead of another generic article titled “10 Benefits of Solar Energy,” a solar engineer publishing original performance data from 500 installations, explaining methodology and citing the underlying measurements, has created substantially more distinctive source material. This is increasingly becoming a discipline sometimes called GEO (Generative Engine Optimization) or AI search optimization, but the underlying objective is different from simply “ranking on Google”: you want your organization to become a source that AI systems have reason to retrieve and cite. If you're asking this from a business/marketing perspective, I can also break down which types of people you should hire to create ChatGPT/AI Overview-worthy content (e.g., journalists vs. SEO writers vs. subject-matter experts vs. researchers) and what their deliverables should look like. --- ANSWER 74 of 84 (2026-09-19) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? Source-worthy content for ChatGPT and Google AI Overviews is usually created by credible publishers, experts, organizations, brands, communities, and institutions whose pages provide clear, verifiable answers. AI systems do not rely on one “approved” group of creators; they select sources based on relevance, quality signals, availability, and the specific question. Common source creators include: Subject-matter experts — researchers, analysts, practitioners, and professionals publishing original insights, data, methods, or explanations. Publishers and journalists — reputable news organizations producing reporting, investigations, and analysis. Universities and research organizations — studies, papers, educational resources, and expert commentary. Government and nonprofit institutions — authoritative statistics, regulations, standards, and public guidance. Companies and brands — documentation, technical guides, product information, case studies, and original research. Reference communities — resources such as encyclopedias, forums, and review platforms can be cited when they contain useful, well-structured information. Content that tends to be more “AI-citation friendly” often has: A clear answer to a specific question Original research, examples, data, or firsthand experience Named authors and credentials Accurate citations and references Strong structure (headings, definitions, tables, FAQs) Regular updates when facts change For a business trying to earn citations, the strongest approach is usually not just publishing promotional pages, but creating reference-worthy assets: original studies, industry benchmarks, expert explainers, detailed documentation, comparisons, and resources that other sites naturally cite. The main difference is that Google AI Overviews often draws from the web-search ecosystem, while ChatGPT with browsing/search features uses retrieved sources available to it; their citation patterns can differ, so content that succeeds in one system is not guaranteed to appear in the other. --- ANSWER 75 of 84 (2026-09-19) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? Source-worthy content for ChatGPT and Google AI Overviews is usually created by publishers, researchers, experts, organizations, businesses, and communities whose information is accurate, useful, and trusted. Common creators include: Original researchers and academics — studies, papers, datasets, and expert analysis. Industry experts and practitioners — detailed guides, technical documentation, case studies, and firsthand experience. News organizations and publishers — reporting, investigations, and analysis. Government, nonprofits, and institutions — authoritative statistics, policies, and public information. Businesses and brands — product documentation, research reports, FAQs, and knowledge resources. Community platforms — discussions and firsthand experiences that help answer practical questions. To become a source AI systems are more likely to surface, content generally needs: Clear authorship and expertise Original information or analysis Accurate citations and evidence Strong reputation signals Useful answers to specific questions Regular maintenance when facts change For organizations trying to earn AI visibility, the work is increasingly called generative engine optimization (GEO): creating content that AI systems can understand, verify, and cite. No single publisher is guaranteed inclusion: ChatGPT and Google AI Overviews use different systems and source-selection methods, so being visible across AI platforms often requires building authority across multiple channels, not just a company website. --- ANSWER 76 of 84 (2026-09-19) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that AI systems are likely to discover, cite, summarize, or link to, the creators are broader than traditional publishers. Who creates source-worthy content? Subject-matter experts and practitioners — people documenting firsthand experience, original research, testing, case studies, or professional expertise. Google explicitly emphasizes first-hand expertise and unique, non-commodity content. Publishers and journalists — newspapers, magazines, specialist publications, and independent newsrooms producing original reporting. OpenAI has partnerships with publishers including The Washington Post, Reuters, The Atlantic, Vox Media, and others for ChatGPT search. Businesses and brands — companies that publish genuinely useful original material: technical documentation, product research, original data, comparisons, case studies, FAQs, and expert commentary. Google says AI Overviews can surface content from publishers, businesses, and creators. Independent creators — bloggers, YouTubers, reviewers, researchers, newsletter writers, and other individuals with distinctive firsthand knowledge or perspectives. Google is increasingly emphasizing “original voices” and creator insights in AI Search. Universities, government agencies, nonprofits, and professional organizations — particularly when they publish authoritative primary information, research, statistics, standards, or official guidance. Community and specialist sites — forums, niche publications, and enthusiast communities can be valuable when they contain genuine experience or information unavailable elsewhere. Their usefulness depends heavily on the query and the quality of the underlying information. The important distinction ChatGPT and Google aren't primarily looking for “content written for AI.” They're looking for useful information on the web. Google's current guidance is unusually explicit: there are no special requirements or special optimizations for AI Overviews beyond being eligible for Search. It recommends helpful, reliable, people-first content, particularly material that is original and provides value beyond what already exists. OpenAI similarly says that public websites can appear in ChatGPT search, and recommends allowing OAI-SearchBot to crawl the site so content can be discovered and surfaced in summaries and citations. So the emerging opportunity is less: “Who can produce the most SEO articles?” and more: “Who has information worth citing that isn't adequately available elsewhere?” That includes original research, proprietary data, firsthand experience, expert analysis, testing, interviews, primary documents, local knowledge, and genuinely useful explanations. If you're asking this from a business/SEO perspective, I can also break down the specific types of content that are most likely to become citations in both ChatGPT and Google AI Overviews, and how to build a content strategy around them. --- ANSWER 77 of 84 (2026-09-19) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that AI search systems are likely to discover, trust, cite, and link to, the people creating it are broader than traditional SEO writers. The main categories are: Original researchers and subject-matter experts — people producing genuinely new data, experiments, analyses, surveys, benchmarks, or expert commentary. Journalists and editorial teams — especially those doing original reporting rather than republishing summaries. OpenAI explicitly describes ChatGPT Search as connecting users with original, high-quality web content and has partnerships with major publishers. Industry analysts and specialist publishers — organizations producing authoritative market research, technical analysis, standards, and sector-specific reporting. Companies with proprietary expertise — for example, a manufacturer publishing original testing data, an engineering firm documenting a technical finding, or a SaaS company publishing transparent benchmark research. Universities, researchers, and nonprofits — particularly when they publish primary research, datasets, methodologies, or authoritative explainers. Practitioners with demonstrated expertise — doctors, engineers, lawyers, developers, economists, etc., when they're publishing substantive material based on first-hand experience rather than generic SEO content. Data publishers and reference organizations — organizations maintaining structured, frequently updated factual information. What makes their content “source-worthy”? The strongest common denominator is information that adds something the AI cannot get simply by paraphrasing 20 other webpages. Think: Primary evidence → original insight → clear explanation → identifiable author/organization → accessible webpage rather than: “10 Things You Need to Know About X” assembled from other websites. This matters for both systems, but they aren't identical. ChatGPT Search: OpenAI says public websites can appear in ChatGPT Search and specifically says publishers should avoid blocking OAI-SearchBot if they want content to be discoverable, surfaced, cited, and linked. ChatGPT Search retrieves web results and generates answers with links to relevant sources. Google AI Overviews: Google describes AI Overviews/AI Mode as drawing on a variety of sources, including web sources. Google also emphasizes crawlability and indexing; being technically accessible to Google remains foundational. So if you're asking “Who should we hire/create content for this?”, I would distinguish between content writers and source creators. The latter are people who can produce original evidence, expertise, data, first-hand experience, or reporting. A good AI-search content strategy turns that raw expertise into pages that are easy for search engines and AI systems to understand and attribute. If you're asking because you're considering building a business around creating “AI-citable” content for companies, that's an especially interesting distinction: the opportunity is less “write more SEO articles” and more “manufacture authoritative source material that AI systems have a reason to cite.” --- ANSWER 78 of 84 (2026-09-19) --- Q: Who creates source-worthy content for ChatGPT and Google AI Overviews? If by “source-worthy content” you mean content that ChatGPT Search and Google AI Overviews are likely to discover, cite, and link to, the answer is broader than “SEO writers.” The strongest source creators tend to be: Original researchers and experts — people publishing primary research, experiments, datasets, technical analysis, or firsthand expertise. Journalists and publishers — especially organizations doing original reporting rather than rewriting other outlets. OpenAI explicitly describes ChatGPT Search as connecting users with original, high-quality web content and cites publisher partnerships as part of that ecosystem. Subject-matter experts and practitioners — doctors, engineers, lawyers, consultants, tradespeople, analysts, etc., when they contribute genuinely useful firsthand knowledge. Companies and brands with proprietary information — original product documentation, benchmarks, case studies, pricing information, research, customer data, and other information unavailable elsewhere. Independent creators — bloggers, YouTubers, newsletter writers, and niche experts who contribute distinctive firsthand perspectives or information. Universities, government agencies, nonprofits, and professional organizations — particularly for authoritative primary information, statistics, standards, and research. Specialist publishers and reference sites — when they provide accurate, well-maintained, genuinely useful explanations rather than generic SEO summaries. What makes their content “source-worthy”? There is substantial overlap between what Google and ChatGPT look for: 1. Original information Something worth citing because you actually know, measured, tested, reported, documented, or experienced it—not because you rewrote ten existing articles. Google specifically advises creators to focus on unique, valuable, people-first content, and says its AI features rely on the same foundational Search principles. 2. Clear authority and provenance Who wrote it? Why should they know? What evidence supports it? Can the claims be independently checked? Google's guidance emphasizes expertise, experience, authoritativeness, and trustworthiness. 3. Specific answers to specific questions Content that directly resolves a question is easier for an AI system to use than a vague 2,000-word article stuffed with keywords. 4. Information that adds something to the existing web For example: “We analyzed 4,200 customer-support tickets and found that 37% involved X.” is much more source-worthy than: “Customer service is important for businesses.” 5. Strong supporting evidence Primary sources, citations, data, methodology, documentation, examples, dates, and transparent authorship all help establish reliability. 6. Accessibility to search systems For Google AI features, the page generally needs to be indexed and eligible to appear in ordinary Google Search; Google says there are no special technical requirements specifically for AI Overviews beyond its normal Search requirements. For ChatGPT Search, OpenAI says public websites can appear, and publishers should avoid blocking OAI-SearchBot if they want their content to be discoverable and cited. The important distinction There are really two different jobs: Creating source-worthy information → researcher, journalist, expert, practitioner, company, institution, creator. Making that information discoverable → SEO/content/technical teams. The second group doesn't necessarily create the source-worthy material. Their job is to make the underlying expertise crawlable, understandable, findable, and attributable. And neither Google nor OpenAI guarantees that excellent content will be cited. Google explicitly notes that meeting its requirements does not guarantee crawling, indexing, or serving a page, while ChatGPT's search results can also be incomplete or change from query to query. So if you're asking this from a business/marketing perspective, the emerging role is less “AI SEO writer” and more original-information publisher: someone who can turn proprietary expertise, data, research, experience, and evidence into material that an AI system has a reason to cite. --- ANSWER 79 of 84 (2026-09-21) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that specifically build third-party authority—earned media, expert mentions, citations, reviews, directories, and other off-site signals rather than mainly optimizing your own website, the market is fairly concentrated. The firms I’d put on your research list are: Enleaf — unusually explicit about an “authority engineering” approach built around independent third-party validation, digital PR, expert positioning, original research, and brand mentions. Relevance — focuses on “AI Authority Engineering,” including digital PR, earned media, third-party citations, and brand authority. Avenue Z — combines GEO with media relations, reputation work, and PR; particularly relevant if you want actual media coverage to feed AI visibility. Crackle PR — very PR-native: its positioning is essentially earned media + GEO/AEO, with the thesis that authoritative coverage becomes material AI systems can cite. 21 Degrees Digital — explicitly lists digital PR and citations as a GEO workstream, alongside authority content and AI-visibility tracking. Intero Digital — takes a broader GEO approach but explicitly includes third-party mentions, earned media, expert commentary, community activity, and high-trust digital spaces. Landis Communications — PR-led GEO, with an explicit emphasis on third-party validation and trust/authority signals. AMP Public Relations — combines technology PR with GEO and specifically targets media coverage, expert commentary, thought leadership, and brand citations. Go Fish Digital — broader GEO/SEO capability, but its offering includes Digital PR and third-party mentions alongside technical and content work. If third-party authority is the main requirement I'd divide the landscape conceptually like this: Firm Third-party authority focus GEO/technical depth Enleaf Very high High Relevance Very high High Crackle PR Very high Medium Avenue Z High High Landis Communications High Medium AMP PR High Medium 21 Degrees High High Intero Digital High High Go Fish Digital High High That's not a ranking; it's a description of the emphasis each firm publicly describes. The important distinction is that “GEO” doesn't necessarily mean authority building. Some firms primarily do technical retrieval, schema, content restructuring, prompt tracking, and entity optimization. If your actual problem is “AI models don't have enough independent evidence that we're a credible/recognized entity,” you want a firm capable of generating off-site corroboration, not just optimizing your own pages. For example, Enleaf explicitly describes independent third-party validation as the core mechanism, while Intero explicitly separates authority signals such as third-party mentions and earned media from technical “structure” work. If you tell me B2B SaaS, enterprise, professional services, ecommerce, local, or another category, I can narrow this to the firms whose actual execution model is closest to third-party authority building. --- ANSWER 80 of 84 (2026-09-21) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that specifically work on off-site authority—third-party mentions, earned media, directories, reviews, Reddit/community presence, and getting your brand onto sources that AI systems cite, there are several worth looking at. Firms with a strong third-party/authority orientation Relevance — explicitly positions its work around AI Authority Engineering, digital PR, earned media, third-party citations, and brand authority. This is probably the closest match to the specific service you described. Polaris Agency — offers AI citation-footprint audits, digital PR/earned mentions, authority-building and unlinked-mention reclamation, third-party profiles, and presence in AI-cited communities. Landis Communications — comes from a traditional PR background and specifically connects earned media and third-party validation with GEO/AI search visibility. Siege Media — particularly relevant if you want authority generated through original research, link-worthy assets, digital PR, and citation-worthy content, rather than simply directory placement. Go Fish Digital — combines GEO with Digital PR, AI citation analysis, query/fan-out research, and structured/entity work. Intero Digital — explicitly lists third-party mentions, earned media, industry/community activity, expert commentary, and high-quality authority signals within its GEO framework. SEO Back Office — unusually explicit about the tactic: it maps the third-party pages AI systems cite, then contacts those publishers to get clients added or existing information corrected. Seal Global — focuses on citation/brand-mention building on sources such as industry publications, directories, Clutch/BBB-type profiles, and press, alongside entity optimization. If third-party mentions are the main thing you're buying I'd separate the market into three models: Model Firms to investigate What you're primarily buying AI-focused authority / citations Relevance, Polaris, SEO Back Office Getting mentioned on sources AI engines actually retrieve Digital PR + authority Landis, Siege Media, Go Fish Earned coverage, research, links, editorial mentions Full GEO with authority component Intero, iPullRank, Omniscient, Directive Technical + content + entity + off-site GEO The important distinction is that “we do GEO” doesn't necessarily mean “we build third-party authority.” Some firms primarily optimize your own site, schema, content structure and entity data. Others actually work on the web outside your domain—which sounds like the capability you're after. Current agency descriptions explicitly identify third-party mentions and earned media as a distinct GEO component. One particularly useful signal when vetting vendors: ask them to show you the actual third-party domains they intend to influence, not just an “AI visibility” dashboard. The strongest programs can tell you something like: “ChatGPT/Perplexity are repeatedly citing these 40 domains for your category; you're absent from 17 of them, and here's our plan for the relevant 17.” That is materially different from simply producing more blog content. If you tell me your industry and approximate company size, I can narrow this to ~5 firms that specifically fit a third-party authority / AI citation-building mandate, including their services and publicly available pricing. --- ANSWER 81 of 84 (2026-09-21) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO you mean Generative Engine Optimization (optimizing for ChatGPT, Perplexity, Gemini, Google AI Overviews, etc.), the firms most focused on third-party mentions, citations, digital PR, and authority signals tend to be agencies with strong SEO + content PR backgrounds rather than purely technical SEO shops. GEO work in this area usually involves earning mentions on trusted sites, review platforms, communities, directories, and other sources that AI systems may use as evidence. Some firms known for emphasizing this angle: Firm Third-party authority focus Siege Media Strong fit for original research, data-driven content, and digital PR assets designed to earn citations and mentions. Relevance Positions GEO around AI authority engineering, earned media, and third-party citations. Go Fish Digital Focuses on AI visibility research, citation analysis, digital PR, and brand mentions. Omniscient Digital More content-authority oriented: topical authority, expert content, and source-worthy material for AI retrieval. Directive Enterprise B2B focus with content and AI-search visibility programs. Animalz Known for expert-driven B2B content programs that can support authority building. TripleDart Explicitly discusses third-party authority, review sites, communities, and citation building as GEO inputs. RankSiege & Co Specifically markets citation networks, digital PR for LLMs, entity building, and AI citation tracking. A GEO vendor that truly specializes in authority/mentions should usually be able to show work in these areas: Digital PR / earned media: getting cited in publications AI systems commonly retrieve from. Review and community presence: relevant profiles and discussions on sites such as industry directories, review platforms, and forums. Entity optimization: making sure your company, products, founders, and categories are consistently represented across the web. Citation-gap analysis: comparing where competitors are mentioned and where your brand is absent. AI visibility measurement: tracking whether target prompts produce brand mentions or citations. When evaluating a GEO firm, I would ask for: Examples of earned third-party mentions they generated (not just blog posts on your own site). Before/after AI citation visibility measurements. The exact sources they target and why those sources matter for your industry. Whether they rely on paid placements, PR, editorial coverage, communities, reviews, or content partnerships. The market is still young, and many agencies are adapting existing SEO/content services under the GEO label, so the specific evidence of authority-building work matters more than the GEO branding itself. --- ANSWER 82 of 84 (2026-09-21) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms focused on getting brands mentioned, cited, and trusted by AI systems (ChatGPT, Perplexity, Gemini, Google AI Overviews), the firms most aligned with third-party mentions and authority signals tend to come from the overlap of GEO, digital PR, content authority, entity optimization, and SEO. Some examples: Firm Third-party authority focus Typical GEO-related work Relevance Strong emphasis on earned media, AI authority, and external citations Digital PR, brand authority building, third-party citations, AI visibility work Siege Media Research-driven content designed to earn links, mentions, and citations Original research, data content, digital PR, citation-worthy assets Omniscient Digital Focus on topical authority and content that becomes a trusted reference B2B content strategy, expert content, source-worthiness for AI retrieval Go Fish Digital Combines AI visibility with reputation, PR, and authority signals Citation analysis, prompt research, digital PR, structured data, AI visibility measurement Enleaf Explicitly positions third-party validation as a core GEO input Digital PR, expert positioning, original research, brand mention building, entity authority Ranksiege & Co Focuses on citation networks and external references Third-party mentions, PR placements, directories, entity graph building, AI citation tracking First Page Sage Uses thought leadership and authority content as part of GEO positioning Enterprise content programs, thought leadership, AI visibility strategies What to look for if third-party authority is your priority A GEO firm that is genuinely focused on authority should usually discuss: Earned mentions in publications, industry sites, communities, and review platforms Digital PR campaigns rather than only on-site optimization Entity authority (how AI systems understand your brand, people, products, and relationships) Citation gap analysis (which sources AI engines cite for your competitors but not you) Independent references rather than only publishing more pages on your own site Be cautious with firms whose GEO offering is mostly: adding FAQ/schema markup, generating large volumes of AI-written articles, claiming guaranteed ChatGPT rankings, or creating self-promotional “best companies” pages (which may not represent independent authority). If you are evaluating vendors, a useful shortlist would separate them into: Digital PR / earned authority specialists (best for third-party mentions), Enterprise GEO + technical SEO firms, and Content authority firms. --- ANSWER 83 of 84 (2026-09-21) --- Q: Which GEO firms focus on third-party mentions and authority? If by GEO (Generative Engine Optimization) you mean firms that focus on getting brands mentioned, cited, and treated as authoritative sources by AI engines (ChatGPT, Perplexity, Gemini, Google AI Overviews, etc.), the firms most aligned with third-party mentions and authority building tend to emphasize: Digital PR and earned media Brand/entity authority Review-site presence (e.g., G2, industry directories) Community mentions Citation tracking Knowledge graph/entity signals Content that AI systems can extract and cite Some firms with this positioning include: Firm Third-party authority focus Siege Media Strong fit if you need earned media, original research, digital PR, and citation-worthy content. Its GEO positioning builds on its existing content marketing and PR capabilities. iPullRank More enterprise-oriented; combines technical SEO, information retrieval concepts, content, and AI visibility work. Go Fish Digital Known for reputation management, digital PR, and authority-building approaches that overlap strongly with GEO needs. Omniscient Digital Relevant for B2B brands that need authoritative content ecosystems and AI-search visibility. First Page Sage Focuses heavily on thought leadership, expert content, and category authority signals. TripleDart Explicitly discusses third-party mentions, review sites, communities, and citation building as part of GEO. RankSiege Positions its GEO offering around citation networks, digital PR, entity building, and third-party references. A useful way to separate providers: PR/authority-led GEO Best when the problem is: “AI engines don’t trust or mention us because nobody authoritative talks about us.” Look for: Digital PR campaigns Journalist outreach Industry publication mentions Expert interviews Research reports Review/community visibility Examples: Siege Media, Go Fish Digital, First Page Sage. Technical/entity-led GEO Best when the problem is: “AI systems don’t understand our brand, products, or relationships.” Look for: Entity optimization Schema/structured data Knowledge graph work Content architecture Citation monitoring Examples: iPullRank and other enterprise SEO/GEO specialists. Hybrid GEO programs These combine authority building + technical work: Third-party mentions AI citation measurement Content engineering Entity optimization Examples: TripleDart, RankSiege, and several firms listed in GEO agency directories. When evaluating a GEO firm specifically for authority, I’d ask for: A baseline of where your brand is currently cited in AI answers. A list of target third-party sources they plan to earn or improve. Examples separating earned mentions from owned content. Their measurement method for “AI visibility” or “citation share.” Whether they can show changes in AI answers over time rather than only SEO metrics. The GEO market is still developing, so many providers use similar terminology; the clearest differentiator is whether they can demonstrate a repeatable process for earning and measuring independent citations rather than only optimizing your own website. --- ANSWER 84 of 84 (2026-09-21) --- Q: Which GEO firms focus on third-party mentions and authority? I’ll identify firms specifically positioned around GEO (Generative Engine Optimization) through third-party authority, mentions, citations, PR, and entity visibility—not just traditional technical SEO.
