AI Overview citations are decoupling from search rank

Ranking in the top 10 used to be the closest thing to a guarantee of an AI Overview citation. Ahrefs data now puts that guarantee at less than four in ten.

The numbers#

Ahrefs first measured the relationship between rank and AI Overview citation in July 2025, analysing 1.9 million citations sourced from 1 million AI Overviews. It found 76.1% of cited pages ranked in the top 10, with the primary citation in each Overview landing at a median organic position of 2.

In a March 2026 update, Ahrefs ran the same question against a larger sample: 863,000 keyword SERPs and 4 million AI Overview URLs. Top-10 pages now account for 38% of citations. Pages ranking 11 to 100 account for 31.2%, and pages that do not appear in the top 100 at all account for 31.0%, meaning more than six in ten citations go to pages outside the top 10. Ahrefs counted ads and SERP features as blocks in this first test, and it notes it has improved its parsing since the 2025 study, so the two figures are not strictly like for like.

Ahrefs notes that AI Overviews have been powered by Gemini 3 since January 2026, and suggests that query fan-out may now play a bigger role in source selection. Google has confirmed that fan-out splits the typed query into related sub-queries; the pages that appear most often across those SERPs then get cited, not just the top results for the original query.

What Google says on placement#

Ahrefs’ data describes which pages get cited. A separate change, confirmed directly by Google, describes how a citation is placed once a page is chosen. In a May 2026 post on the Google blog, the company said you will see “more links directly within AI responses”, “right next to the relevant text,” giving the example of a bike-trip guide linked beside the specific bullet point about terrain.

Google did not publish a ranking-factor formula alongside that change, and neither Ahrefs nor Google has published a study proving passage relevance outweighs backlinks or domain authority in citation selection. What is confirmed, directly from Google, is the placement behavior: links now sit next to the relevant text. Whether a page whose supporting detail is buried inside a long paragraph is cited less often is our inference, not a published finding.

Why we care#

The two data points point at the same practical shift from different directions. Ahrefs shows that rank alone no longer predicts citation with the confidence it did eight months earlier. Google says links now sit beside the specific text they relate to. Our reading, not a published finding: a page needs to rank well enough to be crawled, trusted and considered, then separately needs a clearly stated, self-contained answer for a citation to land, and the number that tells you whether the second half is working is citation rate, not position. Tools that report the two separately, rather than assuming one predicts the other, are now measuring something rank tracking cannot.
