Our Amazon agency is not working out. Who should we move to?
Switching Amazon Agencies? What The Shortlist Report Finds
2 firms lead, appearing in 44.1–46.5% of 299 AI responses. The sample cannot separate them, so we do not pretend it can.

Canopy Management132 of 299
Delivers full-service Amazon management including PPC, listings, A+ content, advertising and marketplace growth operations.
Based on 299 ChatGPT responses to this question, collected August 11, 2026–October 7, 2026. Firms are counted once per response. How we measure.

Key findings
- Tinuiti and Canopy Management lead this sample, each named in 44.1–46.5% of 299 ChatGPT responses to the question “Our Amazon agency is not working out. Who should we move to?”, collected August 11, 2026–October 7, 2026.
- The gaps between Tinuiti and Canopy Management are inside the margin of error at 299 responses, so The Shortlist Report groups them in one tier rather than ranking them against each other.
- 10 firms cleared the reporting threshold on “Our Amazon agency is not working out. Who should we move to?” in ChatGPT as of October 7, 2026; the full table with response counts is below.
- Tinuiti appears in 8 of the 14 Amazon agencies reports published by The Shortlist Report, the widest coverage of any firm named on this page.
- No firm paid to appear in this ranking; placement cannot be bought, and the counts come from ChatGPT responses rather than from submissions.
Why the tiers fall where they do
Tier 1 holds Tinuiti and Canopy Management, named in 132 to 139 of the 299 ChatGPT responses. They are grouped rather than ranked because the gaps between them are inside the margin of error at this sample size — one extra mention would reorder them, so an order would be reporting noise as a finding.
Tier 2 holds Acadia, Nuanced Media and Olifant Digital, named in 53 to 73 of 299 responses (17.7–24.4%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.
Tier 3 holds My Amazon Guy, SalesDuo and Amazon Growth Lab, named in 35 to 50 of 299 responses (11.7–16.7%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.
Tier 4 holds Teikametrics and BellaVix, named in 26 to 33 of 299 responses (8.7–11.0%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.
The test is McNemar’s at 95%, applied against the same 299 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.
What the sample shows
2 firms lead this question: Tinuiti and Canopy Management. They appear in 44.1–46.5% of the 299 responses. The gaps between them are inside the margin of error at this sample size, so they are listed together rather than ranked against each other.
115 firms were named at least once across the sample. 10 of them cleared the threshold of 2 responses and appear above; the rest were named once and are inside the noise.
How to read this
Firms are grouped into tiers, not ranked one to fifteen. A tier holds every firm whose 95% confidence interval overlaps the leader's, which is a long way of saying the sample cannot tell them apart. Order within a tier is arbitrary — read the counts, not the position.
Share is the percentage of responses that named the firm — not a quality score. A firm scoring low here may be excellent and simply under-written about online, which is a finding about its visibility rather than its work.
The same question was asked repeatedly because AI assistants do not answer identically twice. A single response would tell you almost nothing.
What this measurement does not tell you
- It is not a quality ranking. Share reflects how much has been written about a firm online, which is what an AI assistant reads. A capable firm nobody writes about scores low here.
- It is a reading from a date range, not a permanent standing. This sample was collected August 11, 2026–October 7, 2026; models change and so do their answers.
- It covers ChatGPT only. Other assistants answer differently, and we do not extrapolate across engines we have not measured.
- Order within a tier is arbitrary. Read the counts, not the position. Why we use tiers.
