Do AI Overviews Reduce Clicks? What the Evidence Says (and What Gets Cited)
The best independent data shows fewer clicks when an AI summary appears. Google says total clicks are stable. Both can be true for different sites and queries.
Pew Research Center analyzed the browsing activity of 900 US adults who agreed to share it, covering Google searches in March 2025. It’s one of the few independent studies based on real user behavior rather than tool estimates.
Google responded in August 2025 that total organic clicks were relatively stable year over year, while traffic was shifting between sites. This guide sets out what each source says and what it means for your site.
Short answer: Pew found that when a Google search showed an AI summary, users clicked a traditional result in 8% of visits versus 15% without one, clicked a link inside the summary in just 1% of visits, and ended their browsing session more often (26% vs 16%). Google says overall organic click volume has been relatively stable and that “quality clicks” have slightly increased, with traffic shifting toward sites offering first-hand perspectives. The effect varies by query type, so measure your own impressions in Search Console’s Generative AI reports alongside clicks.
Key Takeaways
- Pew: 8% click rate with an AI summary vs 15% without.
- Pew: only 1% of visits clicked a link inside the summary.
- Google: total organic clicks relatively stable; traffic shifting between sites.
- Question-style and longer queries trigger AI summaries most.
- Measure your own AI impressions and clicks; averages hide big differences.
What Pew found
| Finding (March 2025 searches) | Result |
|---|---|
| Searches producing an AI summary | 18% |
| Clicked a traditional result: with AI summary | 8% of visits |
| Clicked a traditional result: without AI summary | 15% of visits |
| Clicked a link inside the AI summary | 1% of visits |
| Ended browsing session after the search page | 26% with summary vs 16% without |
| AI summaries citing three or more sources | 88% |
| Median AI summary length | 67 words |
Pew also found that around two-thirds of all searches, with or without a summary, ended with the user browsing elsewhere on Google or leaving without clicking a result.
Which queries trigger AI summaries
- 8% of one- or two-word searches produced an AI summary, rising to 53% for searches of ten words or more.
- 60% of searches starting with who, what, when or why produced one.
- 36% of searches containing both a noun and a verb (full sentences) produced one.
Short commercial and local searches are less likely to show summaries than long informational questions, so informational content is where reduced clicks are most likely (impressions up, clicks down).
What gets cited
- Wikipedia, YouTube and Reddit were the most cited sources in both AI summaries and standard results, about 15% of AI summary sources.
- Government (.gov) sites made up 6% of AI summary sources vs 2% of standard results.
- News sites were 5% of sources in both.
- Google’s own guidance stresses non-commodity content with first-hand experience, and says traffic is shifting toward sites with authentic, first-hand perspectives (citable content).
Pew’s data doesn’t show which page formats win citations beyond source types, so be wary of claims that one format guarantees AI Overview citations.
Google’s position
- Total organic click volume from Search has been relatively stable year over year (Aug 2025).
- “Quality clicks”, where users don’t quickly return, have slightly increased.
- People search more and ask longer questions, and see more links on the page.
- Quick-answer queries may get fewer clicks, as with earlier answer features.
- Google disputes third-party reports of dramatic aggregate declines as methodologically flawed.
What it means for your site
- Check Search Console’s Generative AI performance reports for impressions in AI features (measuring AI visibility).
- Segment queries: informational questions vs commercial and local terms.
- Protect commercial pages: service, product and category pages are less exposed.
- Make informational content the kind people click through for: original data, expert depth, tools (linkable content).
- Decide deliberately about opting out; Google now offers a control (opting out).
Frequently asked questions
Is Pew’s study representative?
It’s based on 900 US adults’ real browsing in March 2025; it’s strong evidence but a snapshot, and AI features have changed since.
Who is right, Pew or Google?
They measure different things: Pew measures click rates on pages with and without summaries; Google reports total clicks across the web. Both can be true while individual sites gain or lose.
Will AI Overviews cost my business leads?
It depends on your queries. Track AI impressions, clicks and conversions by query type for your own site.
