About the numbers

  1. The three words this page uses: collected = Grades.com pulls reviews from the site (54 review sites in all); measured = every review site the AI answers cited, across all industries (109 sites); cited for B2B companies = the measured sites that appeared in at least one of the 623 answers about B2B companies (43 sites).
  2. Data window: Aug 1 to Oct 30, 2026 (90 days), October 2026 edition, data as of October 30, 2026.
  3. AI citation share: answers citing the site divided by the 623 AI answers about B2B companies (businesses whose brand the Grades.com directory files under "B2B"), from ChatGPT, Claude, Gemini and Perplexity. The chart and the table rank the sites cited in 20 or more of these answers. Search-result and help pages on a review site are not counted.
  4. Has a profile: the share of the B2B companies we checked with a profile on the site (n = businesses checked).
  5. Picks: most cited by AI = highest citation share; easiest to get reviews = the site cited most whose own rules let anyone review, let the business send a direct review link and allow asking (from its guide; never Yelp, which does not allow asking); most replies from businesses = highest share of reviews with a business reply, across all industries, shown with at least 100 reviews checked. A pick the data cannot support is left out.
  6. Start with these three: the sites cited most for B2B companies that Grades.com collects, one per site Grades.com connects. A site that shows another site's reviews is covered by connecting that site.
  7. Site reach: estimated monthly organic search visits to the site's domain (DataForSEO Labs, Ahrefs Domain Rating, October 2026); an estimate for the whole domain, not a figure published by the site, and the same in every industry.
