# Review sites in AI search — Yelp, G2, Trustpilot shape recommendations

> Peec's 30M-source analysis (Mar 2026) — Yelp, Tripadvisor, Trustpilot, G2 and Clutch all rank in the top 100 cited domains; when AI needs to recommend something, it reads review platforms.

Review platforms quietly shape AI recommendations. In Peec's 30-million-source US analysis ([full study](https://peec.ai/blog/top-domains-cited-by-ai-search-analysis-based-on-30m-sources), Mar 2026), Yelp ranks #7 among all cited domains, and the top 100 includes Tripadvisor, Trustpilot, G2, and Clutch — each serving a different category, from local and hospitality to B2C services and B2B software.

The pattern is consistent: **when AI needs to recommend something, it looks at review platforms.** A business listed on any of them likely has its profile influencing how AI talks about it — so that presence should be accurate, complete, and actively maintained.

Supporting evidence from other 2026 Peec research:

* G2 appears in Perplexity's top 5 sources — see [Most-cited domains by engine](/research/most-cited-domains-by-engine).
* Trustpilot is 54% of the review-category domains ChatGPT targets with the site: operator — see [ChatGPT site-operator fan-outs](/research/chatgpt-site-operator-fanouts).
* ChatGPT injects "reviews" into its hidden searches even when users never ask for reviews, and smaller review sites (e.g. Sitejabber) can drive how AI describes a brand — see [Words ChatGPT adds to fan-outs](/research/words-chatgpt-adds-to-fanouts).
