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 e-commerce brands = the measured sites that appeared in at least one of the 680 answers about e-commerce brands (51 sites).
Data window: Aug 1 to Oct 30, 2026 (90 days), October 2026 edition, data as of October 30, 2026.
AI citation share: answers citing the site divided by the 680 AI answers about e-commerce brands (businesses whose brand the Grades.com directory files under "E-commerce"), 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.
Has a profile: the share of the e-commerce brands we checked with a profile on the site (n = businesses checked).
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.
Start with these three: the sites cited most for e-commerce brands that Grades.com collects, one per site Grades.com connects. A site that shows another site's reviews is covered by connecting that site.
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.
