AI Overviews and SEO: What the Click Data Shows and How to Earn Citations

AI Overviews are AI-generated summaries that Google shows above or among traditional search results for some queries, with links to the sources used. For SEO, they change two things at once: how often searchers click through to websites, and which websites get cited as sources.

What the click data shows

The most rigorous public data so far comes from Pew Research Center, which tracked the actual browsing behavior of 900 U.S. adults who agreed to share it in March 2025. Researchers then collected the matching search results pages to see whether an AI summary appeared and what users did next.

Measure	Without AI summary	With AI summary
Visits with a click on a traditional search result	15%	8%
Visits with a click on a link inside the AI summary	—	1%
Pages where the browsing session ended	16%	26%

Two further details from the same study matter for content strategy: 88% of the AI summaries cited three or more sources, and the median summary was just 67 words long. In other words, AI Overviews tend to compress a topic into a short answer drawn from several pages — so being one of the cited sources is a competitive position, not a guaranteed outcome.

What Google says about AI Overviews

Google’s own guidance is notably simple. According to Google Search Central, there are no additional requirements to appear in AI Overviews or AI Mode, and no special optimizations or schema are needed. To be eligible, a page must be indexed and eligible to be shown in Search with a snippet. The usual SEO fundamentals apply: allow crawling, make content discoverable through internal links, provide a good page experience, keep important content in text form and make sure structured data matches visible content.

Site owners can limit how their content appears using existing controls such as nosnippet, data-nosnippet, max-snippet and noindex. Traffic from AI features is reported in Search Console’s Performance report under the “Web” search type, alongside regular results. Google also states that clicks from results pages with AI Overviews tend to be higher quality, with users more likely to spend more time on the site.

How to earn citations in AI Overviews: the CITE framework

Because there is no special markup, citations are earned by being the clearest, most trustworthy source for a specific question. We use a four-part checklist we call CITE:

Principle	What it means	How to apply it
Clear answers	State the answer plainly near the top of the relevant section	Open sections with a one- or two-sentence definition or answer; follow with depth
Indexable and eligible	The page must be indexed and snippet-eligible	Check URL Inspection; avoid accidental nosnippet or overly restrictive max-snippet
Trust signals	Show who wrote it, how and why	Bylines, about pages, methodology notes and up-to-date facts
Evidence	Support claims with data and primary sources	Original data, charts, tables and links to primary research

Content formats that tend to get cited

• Definitions and explainers that answer “what is” and “how does” questions concisely.
• Comparison tables that summarize options side by side with clear criteria.
• Step-by-step processes with numbered steps and specific outcomes.
• Original data and statistics — the hardest asset for competitors to replicate and the most likely to be referenced.

Rethinking SEO KPIs for AI search

If fewer searchers click, traffic alone becomes a weaker measure of success. Pair it with metrics that reflect visibility and value:

A practical action plan

1. Segment your Search Console queries into informational, commercial and branded groups, and track impressions and click-through rate for each separately.
2. Identify informational pages with rising impressions but falling clicks — these are likely affected by AI summaries.
3. Strengthen those pages with clear answers, original evidence and a reason to click (tools, templates, data, examples).
4. Shift some investment toward commercial and transactional pages, where searchers still need to visit a website to act.
5. Review snippet controls only if you have a clear business reason to restrict how your content appears.

Frequently asked questions

Is there special schema for AI Overviews?

No. Google states there are no additional requirements or special optimizations for AI features. Standard SEO best practices and structured data that matches visible content are sufficient.

Can I see AI Overview traffic in Search Console?

Clicks and impressions from AI features are included in the Performance report under the “Web” search type, combined with regular search results rather than shown separately.

How often do people click links in AI Overviews?

In Pew Research Center’s March 2025 study, users clicked a link inside an AI summary on 1% of visits to results pages that showed one.

Should I block my content from AI Overviews?

Only with a clear reason. Restricting snippets can also limit how your pages appear in regular results. For most businesses, earning citations is the better strategy.
