GTM AI Recommendation Index, September 2026 Edition. Page: https://gtm-ai-index.com/research/what-the-answers-cite/

Four of the twelve models return the sources they read before answering. Across the 1,503 answers that carry a source list, 13,814 citations name 517 sites. This page counts them: which sites the answers cite, how much of the citing goes to the vendors themselves, and how much to the review sites that sell placement. It is a fact about retrieval, not a lever on the model.
