In July 2025, 76% of the pages cited in Google's AI Overviews also ranked in the top 10 for the query. By early 2026 Ahrefs measured 37.9%. AI Overviews still draw only on pages Google has indexed, and ranking still helps, but a page sitting at position 15 is now a realistic candidate. Getting in comes down to three things Google either documents or measurably rewards: be eligible for Search, answer the sub-questions Google fans out to, and be the page attached to the sentence that matters.
Do you still need a top-10 ranking?
It helps, and it is no longer required. Ahrefs' study of 863,000 keywords and about 4 million AI Overview URLs found 37.9% of citations came from top-10 pages, 31.2% from positions 11–100 and 31.0% from pages ranking beyond 100.
The caveat in that chart matters: Ahrefs changed how it detects citations between the two measurements, so not all of the drop is Google. A second dataset points the same way, though. SE Ranking found only 19% of AI Overview sources in the organic top 10. Two vendors, different methods, same direction.
What Google says about how AI Overviews pick sources
Google's AI features documentation is short, and three lines in it do most of the work:
- Eligibility. "To be eligible to be shown as a supporting link in AI Overviews or AI Mode, a page must be indexed and eligible to be shown in Google Search." Googlebot is the only crawler involved.
- No special markup. "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." No schema type, llms.txt file or AI-specific tag is required.
- Fan-out. Both features "may use a 'query fan-out' technique — issuing multiple related searches across subtopics and data sources." It is one likely reason pages ranking far down for the main query still get cited (Ahrefs names fan-out as one cause): they rank for one of the sub-searches.
Our reading of the fan-out line, which Google does not spell out: each section of a page should answer one sub-question someone would plausibly ask next, in its first sentence or two. A comparison table, a price, a definition or a step list is the kind of block a sub-search can land on.
How the citation is shown has also changed. Since May 2026, AI Overviews and AI Mode place more links inline, next to the text they support, with hover previews on desktop and creator names for forum and social sources (Search Engine Land, 6 May 2026). Being the link beside the key sentence matters more than your position in the source list.
AI Overviews are turning into AI Mode answers
Two late-summer changes push in the same direction. Google confirmed that on some queries AI Overviews now expand by default into the full answer, with the "Ask anything" box that feeds AI Mode, which pushes the organic results further down the page (reported 30 August 2026, Shopifreaks summary of Search Engine Roundtable). And Google has been testing links inside AI Overviews that open AI Mode instead of a website (Search Engine Roundtable, 22 September 2026).
The more of the page the AI answer occupies, the more a citation inside it is worth relative to a blue link below it.
What is an AI Overview citation worth in clicks?
The two newest studies point in different directions, and both are worth knowing. Ahrefs' February 2026 update (300,000 keywords, December 2025 data) found an AI Overview correlates with a 58% lower click-through rate for the top-ranking page, up from 34.5% a year earlier. Seer Interactive's April 2026 update (53 brands, 5.47 million queries) found organic CTR on AI Overview queries recovering, from a low of 1.3% in December 2025 to 2.4% in February 2026, and a large gap between cited and uncited pages:
Seer's data also shows where Overviews appear: on 95.4% of comparison queries and 85.9% of question-format queries, against 27.3% of single-word informational ones. Across all queries, vendor estimates of AI Overview coverage range from about 43% (Similarweb) to 48% (Semrush), with no published methodology behind either (Relevant Audience summary). If your pages target comparisons and questions, assume an Overview is there.
Citations reshuffle when the model changes
When Gemini 3 became the default model for AI Overviews on 27 January 2026, SE Ranking found 42.4% of previously cited domains replaced across 100,000 keywords, mostly in long-tail queries. Sources per Overview rose from 11.55 to 15.22, and the number of distinct cited domains grew 9.3%. The shift lines up with the model swap, not with anything publishers did. The May 2026 link redesign was another such event. If a citation vanishes in the weeks after a change like that, sample before you rewrite; the diagnostic is in why an AI Overview citation disappeared.
How to leave AI Overviews, and why you might not want to
Until mid-2026 the only way out of AI Overviews was to leave Google Search too. That is no longer true.
| What you do | Effect on Search | Effect on AI Overviews and AI Mode |
|---|---|---|
| Block Googlebot in robots.txt | Removed | Removed |
| Turn on Search Console's Search generative AI control | No ranking effect, per Google | Excluded within 1–2 days (also Discover AI features) |
nosnippet, data-nosnippet, max-snippet | Limits snippets | Limits what can be shown from the page |
Disallow Google-Extended | None | None on appearance; it governs Gemini app grounding and training |
The Search Console control reached every site worldwide on 31 August 2026 (Google help). It does not affect AI training; Google points to Google-Extended for that, as explained in the Gemini controls guide.
Before switching it on, look at Seer's numbers above. The Overview still appears for your queries with other sites cited in it, so opting out most likely puts you in the "not cited" row rather than the "no Overview" one. That's our reading, not something anyone has measured yet.
Measuring: start with the Search Console report
Every site now has the data Google offers. Search Console's generative AI report, announced in June 2026 and available to all sites since 31 August (Search Engine Journal), shows impressions in AI Overviews, AI Mode and Discover AI features by page, country, device and date. It has no clicks, CTR, position or query data.
A first pass that uses it well:
- Export the pages with AI feature impressions. These are your proven candidates.
- Cross them with the standard Performance report to find pages that rank 11–30 for comparison or question queries but show no AI impressions. Those are the rewrite list.
- For a handful of target queries, check the Overview itself over several days and record which sentence it links you from. How to track AI citations covers how many checks a reliable rate needs.
Page-level writing guidance (answer-first sections, attributed claims, named authors) is the same for every engine and is in what is AEO. Google's quality guidelines weigh experience and expertise most heavily on YMYL topics, and AI Overviews draw on the same ranking systems, so named authorship matters most there; see Article schema and E-E-A-T.
