We checked how AI tools cite 1,000 Shopify stores. Brands got 2.8% of citations. sherocommerce.com

8,573 product descriptions, 60 buying categories, 3 AI tools (Google AI Mode, ChatGPT, Perplexity). Of 1,851 cited sources, 2.8% were a brand\'s own page, and 59% were publishers. 20% of product descriptions appear verbatim on other domains through syndication. The thin content assumption also fails: 30% of description fields are under 50 words, but 71% of those stores serve rich pages on raw HTML.
