AI engines recommend brands based on the third-party evidence they can retrieve at answer time, and the strongest measured predictor is how often a brand is mentioned across the web: in an Ahrefs analysis of 75,000 brands, branded web mentions correlated with AI Overview visibility at 0.664, roughly double the strength of Domain Rating at 0.326 [4]. Earned coverage supplies most of the raw material, since 84% of citations across ChatGPT, Claude, and Gemini point to earned media while paid and advertorial content accounts for 0.3% [7]. Platforms document some of this behavior directly: Google states a page must be indexed and snippet-eligible before it can support an AI answer [1], and OpenAI says ChatGPT's shopping recommendations are organic, built from product metadata and review discussion rather than ads [13]. Beyond those documented rules, the drivers, including review presence, first-page rankings, content recency, and consistent naming, rest on correlational studies rather than published algorithms, and the correlations are moderate, so no single tactic reliably produces a recommendation [4][5][10].

Earned coverage supplies most of the raw material, since 84% of citations across ChatGPT, Claude, and Gemini point to earned media while paid and advertorial content accounts for 0.3% [7]. Platforms document some of this behavior directly: Google states a page must be indexed and snippet-eligible before it can support an AI answer [1], and OpenAI says ChatGPT's shopping recommendations are organic, built from product metadata and review discussion rather than ads [13].
