Do brand signals matter for AI answers?
Ahrefs analyzed 75,000 brands in May 2025. Brand web mentions correlated most strongly with mentions in Google AI Overviews, with a Spearman coefficient of 0.664. Brand anchors reached 0.527, brand search volume 0.392, Domain Rating 0.326 and backlinks 0.218. Brands in the top quartile for web mentions averaged 169 AI Overview mentions, more than ten times the next quartile at 14.
