Who Google's AI Overviews Actually Cite

We pulled the AI Overview for 40 SEO-related queries and recorded every source each one cited — 251 citations in total — then compared them against the organic results for the same query. The headline: nearly half of all citations came from sites that weren't ranking on page one.

1. Ranking is not the price of admission

The most common assumption about AI Overviews is that Google summarises whatever already ranks. Our data says otherwise.

Across the 32 queries that returned an overview, 120 of 251 citations (48%) pointed to domains that did not appear in the top 10 organic results for that same query. On average, only 57% of an overview's citations also ranked on page one.

Even the top organic result is not guaranteed a mention: the number one result was cited in 22 of 32 overviews (69%) — meaning roughly a third of the time, the page Google ranks first is absent from the answer above it.

Being cited and being ranked are related, but they are not the same competition.

2. Overlap depends heavily on intent

How closely citations track the organic results varies enormously by query type. The more commercial the query, the more the overview simply reflects the ranking pages. The more local or price-driven it is, the more it reaches elsewhere.

Share of an overview's citations that also appear in the top 10 organic results, by query intent.

For local queries such as how to rank in google maps, only 23% of cited sources were also ranking. If you sell to a local audience, the organic top 10 is a poor proxy for who Google's AI actually surfaces.

3. Commercial queries are the safe harbour

Prevalence was not uniform. Every pricing, informational, industry and AI-related query in our set returned an overview. Commercial and tool queries frequently did not.

Query intentShowed an AI Overview
Pricing4 / 4 — 100%
Informational9 / 9 — 100%
Industry-specific5 / 5 — 100%
AI & GEO5 / 5 — 100%
Local3 / 4 — 75%
Commercial4 / 8 — 50%
Tool / software2 / 5 — 40%

Eight queries returned no AI Overview at all. Six of them were the most commercially valuable terms in the set:

  • seo agency, local seo services, small business seo, seo consultant, near me seo
  • schema markup generator, robots txt generator, xml sitemap generator

This is the practical takeaway for anyone worried that AI answers are eating their traffic: the queries where someone is ready to hire or use a tool are precisely where Google is least likely to answer for you. Informational content bears the brunt.

4. YouTube is the most-cited domain — by a wide margin

We expected the usual SEO publishers to dominate. They didn't.

YouTube appeared in 20 of the 32 overviews and accounted for 44 citations on its own. Reddit added 18. Together with other social and community sources, 26% of all citations were user-generated or video content rather than conventional articles.

Meanwhile the field was remarkably fragmented: 251 citations spread across 133 distinct domains, with no single publisher exceeding 11. There is no small club of sites that AI Overviews always quote.

5. What we would actually do with this

Four conclusions we're applying to our own work:

  • Don't abandon informational content — restructure it. Those queries get an overview 100% of the time, but 43% of citations go to non-ranking pages. Being quotable matters as much as being ranked.
  • Protect commercial pages. They're the least affected by AI Overviews and the closest to revenue. This is the strongest argument yet for building service pages, not just blog posts.
  • Video is underpriced. If YouTube is the most-cited domain for your topic and you publish none, you're absent from the largest single source of citations.
  • Local is its own game. At 23% overlap, local citations follow rules the organic ranking barely predicts.

Method, and its limits

We queried Google via the DataForSEO SERP API on 6 August 2026, United States, English, desktop, with asynchronous AI Overview loading enabled so the full citation list resolved. For each of 40 queries we recorded whether an AI Overview appeared, every domain it cited, and the top 10 organic domains. Overlap is measured at domain level.

What this does not prove:

  • 40 queries is a small sample, drawn from one industry — SEO and digital marketing. Other niches may behave differently.
  • One location, one language, one point in time. AI Overviews are personalised and volatile; the same query can differ hour to hour.
  • Domain-level matching counts a citation as "ranking" if any page from that domain is in the top 10 — a generous test, which means the real non-ranking share is likely higher than 48%, not lower.
  • We measured citation, not traffic. Being cited is not the same as being clicked.

We'd rather publish a small honest sample than a large vague claim. If you want the raw query list to replicate or extend this, ask us — we'll send it.
