How we collected the data and how to read it

How we collected this data

Every week, the same frozen set of 4 question phrasings is sent to OpenAI, Anthropic, Google Gemini, and Perplexity — through each provider’s official API, with active web search, never through a consumer chat interface.

Same market, same questions, repeated on a fixed schedule — not a single sample. No AI model is paid or influenced; this page reports what each one already says.

How to read the numbers

Answer Share — the share of measured responses that name a given company. 55.6% means the company appeared in 55.6% of the responses collected for this market.

Market concentration — the share of responses naming at least one of the top 3 companies: how fragmented or concentrated the answers are for this market.

Citation Share — the share of citations linking directly to a company’s own website, among companies whose domain we’ve matched. Shown as n/d where we haven’t matched a domain, or 0% where the domain is known but never cited directly — AI models often cite a review aggregator instead of the company’s own site.

The date at the top of this page is when this market was last measured. Numbers refresh weekly.

Methodology: 4 AI models (OpenAI, Anthropic, Google Gemini, Perplexity), 4 question phrasings per measurement, data collected via official APIs with active web search. No payment influences this ranking. Read the full methodology →
