See the Montréal pageIn Brussels, the AIs cite Golden Pages in English, Gouden Gids in Dutch and comparison sites in French. In Luxembourg, Editus in all three languages. The counts, by city, profession and language.
These are the AIs’ answers, not a quality ranking. A business missing from these lists can be excellent. That is exactly the problem.
First name cited, with web search. Question 3 is the direct question, for example “Which dentists in Paris, France are considered the best for my routine dental care?”; the 8 questions of the Presence angle count all answers received.

8 questions for the Presence angle, 7 models, 2 modes, up to 56 answers per mode (the actual number is shown for each list). Failed answers are not counted.
Each figure has a measurement ID, available on request.
The method in detailNot necessarily. Across the professions measured in your city, most businesses are not named in any answer. Those that are change with the language of the question. The Snapshot measures your business in your language and your city.
The AIs search different sources depending on the language: directories, media, websites. In your city, the sources cited in French, English and local languages are not the same. A business visible in one language can be missing in the other.
ChatGPT, Claude, Gemini, Grok, Perplexity and the other AIs of the panel, with and without web search, with 8 identical buyer questions for each profession.
No. They are the AIs’ answers, measured on a given day. A business that is missing can be excellent. That is exactly the problem.
The Snapshot: two targets (two languages, two cities or two personas), the full report with the actions and their proofs, and the second measurement 30 days later. See the Snapshot
