SE Ranking's analysis of 50,000+ keywords reveals ads appear in nearly one-third of commercial AI Mode queries, with no link between ad spend and organic citation likelihood.
SE Ranking analyzed over 50,000 keywords to quantify ad placement in Google's AI Mode and found that ads now surface on nearly 1 in 3 commercial queries. The research indicates that CPC influences ad placement, but critically, buying ads does not improve the likelihood that a site will be cited in the AI-generated overview — a key distinction for organic SEO practitioners evaluating how paid and organic results interact in AI Overviews.
