Methodology
Every month we ask 4 AI assistants (ChatGPT, Claude, Gemini and Perplexity) about the businesses in the Grades.com directory and record every review site each answer cites. A site's AI citation share is the number of answers citing it divided by all answers in the window. Search-result and help pages on a review site are not counted. We also check each business for a profile on every site (coverage), and count how many of its reviews the business answered (reply rate).
Shares by industry use only the answers about businesses in that industry. A site is ranked in a view when at least 20 of its answers cite it; each guide lists its sample size next to every number.
