Microsoft Copilot (a different measurement)
Bing Webmaster Tools reported 557 Copilot citations of agentxray.ai pages over the reported window (3 months, read on 2026-11-09). This counts how often our own pages were used as a source, not which sources Copilot prefers in general, so it is not comparable with the Perplexity figures above.
Method
- Engine: Perplexity's
sonarmodel through its API, web search on. The API model is not guaranteed to match the perplexity.ai app. - Questions: written by AgentXray for its own visibility tracking, tilted towards European sellers, profit and operations. Only questions that name no tool are counted here. A core set is asked daily and the rest weekly.
- Counting: a domain counts once per answer, however many of its links the answer lists. Amazon-owned means any domain under amazon.*. Brand counts use a fixed list of nine brands. Named AgentXray means the tracker found the name in an Amazon-tooling context.
- An edition is published only with at least 200 answers in the month and 20 questions shared with the previous month; otherwise the previous edition stays up.
- Data: CSV for this edition.
Limitations
- One engine and one company's question set: the results describe these questions, not Amazon seller questions in general.
- AgentXray sells Amazon seller software and appears in the data. Our own numbers are reported as they come out.
