Who the assistants recommend

The AI Visibility Index counts the businesses the assistants name, for each place.

See the rankings for roofers

How this was measured

The Index method
The question
Each assistant was asked the questions a buyer asks, with web search on: about a local trade in a city, or about software or a consumer brand in a country. Every page its searches returned and every page it gave as a source was kept.
Counting
A site counts once per answer, however many of its pages the answer read. Read is the share of answers that read at least one page of the site; cited is the share that gave one of its pages as the source of a recommendation.
Sources
A site counts as a source only when it appears on 3 or more pages of the Index. Below that it is almost always a business’s own website or a one-off article.
Edition
October 2026. 108 answers: ChatGPT 88, Claude 20.
Coverage
Not every assistant has answered on every page yet this month, so read each assistant’s shares next to its own number of answers.
