In the US, 30.7% of top-10 organic domains are also cited in the AI Overview

Across the 69 US searches with an AI Overview, 152 of the 495 top-10 organic domains (30.7%) are also cited in that search’s AI Overview source. It varies a lot from search to search: the median search shares 29%, the range runs from 0 to 86%, and 12 searches share no domain at all source.

The first two organic results are the ones most often cited (US)

Of the 69 US searches, the domain in position 1 is also cited in the AI Overview in 44.9% and position 2 in 46.4% source. From position 3 the share falls, to 21.1% at position 7 (57 searches reach a 7th result) source.

The chart stops at position 7, the last with at least 30 searches behind it; position 8 (26 searches, 19.2%) is left out of the chart source. No US search returned a 9th or 10th organic result: SERP features take those slots, so “top 10” here means the organic results the page actually showed, up to 8 source.

Most AI Overview citations come from outside the top 10 (US)

Turned the other way: of the 411 distinct domains the US AI Overviews cite, 63.0% are not among that search’s top-10 organic domains source. That includes 35 opaque Google redirect links, which cannot be matched to any page and so count as outside. Ranking in the top 10 and being cited overlap, but most of what an AI Overview cites sits outside the first page of results.

Matching exact pages, not domains: at least 25.7% (US)

The headline matches by domain. Matching by exact URL instead, at least 25.7% of US top-10 organic pages (118 of 460) are the very page the AI Overview cites source. It is a lower bound: by a fixed rule, 35 of the 495 organic URLs are flagged as cut short to a section or a home page and left out of this share, and the rule cannot catch every cut URL source.

The overlap is about the same for every query type (US)

The overlap barely moves with the kind of query, from 28.8% for doing queries (9 searches) to 31.5% for pricing (13) source. Business queries share 30.2% (62 searches); consumer queries 35.4%, on only 7 source. Each industry has 4 to 8 searches, too few for a finding, so industries are listed for reference only.

The six European markets, each on its own

Each market below stands alone, with its own n. The markets are not pooled into an “EU” figure, and none is compared with the US or with another market: with 4 to 10 searches each, a gap between two markets would say more about the few searches drawn than about the market source. Every per-market measure, including position, is in the downloadable data.

How often the crawler recorded an AI Overview

The share of each market’s usable searches where the crawler recorded an AI Overview source. It is not a ranking of markets. Some European rollouts first showed AI Overviews only to signed-in adults, and the crawler sees a logged-out page, so a lower figure means “recorded by the crawler”, not “Google does not show AI Overviews here”.
