How we measure
We asked ChatGPT 10 questions the way customers ask them, with web search on. That gave 10 answers on 3 November 2026. For each business we count how many answers name it. The measurement is updated every week.
Positions are not for sale. Order and inclusion depend only on how often a business is named, and on review count when that is tied.
