AI search cites a different web than Google rankings

CiteLens Research Lab’s June 29 study found that 60% of the domains cited in 500 Google AI Overviews across 126 categories did not appear anywhere in Google’s organic top 10 for the same query. In the same dataset, 74% of answers cited YouTube and 84% cited forums or other user-generated content.

Ask it in Turkish instead of English and the overlap in cited sources fell to 22%. CiteLens also found instability inside Google’s own answer layer: when the same question was asked three times, the AI kept the full set of cited sources only 81% of the time, which meant about three sources changed on each repeat.

Alper Tekin says AI reads a different web than Google ranks, and classic SEO dashboards miss the source landscape entirely. CiteLens, based in Edirne, Turkey, tracks brand visibility across ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews. It also benchmarks competitors, maps the third-party domains feeding AI answers, and supports English and Turkish markets with country and language targeting.

Google Search Help makes AI Overviews available to more users, in more languages and regions, and the responses provide key information with links to dig deeper while warning that they may include mistakes. At I/O 2024, Google said people had already used AI Overviews billions of times in Search Labs, and at I/O 2025 it said the feature had reached 1.5 billion monthly users in 200 countries and territories, with more than a 10% increase in Google usage in its biggest markets for queries that show AI Overviews.

A Semrush-based study put AI Overviews on 13% of searches in May 2025, while Search Engine Land put 30% of U.S. desktop keywords triggering them by September 2025. Another March 2025 analysis found 82% of AI Overview citations came from deep pages and only 0.5% linked to homepages.
