If AI Overviews cite my site, does that make up for lost clicks?

Not on current evidence. In a Pew panel of US adults, just 1% of visits to Google pages with an AI Overview ended in a click on a cited source, and Wikipedia, one of the most cited sources of all, still lost search traffic. A citation can be worth having, but it is a different thing from a visit, and the two should be measured separately.

The short version

  1. Just 1% of visits to Google pages with an AI Overview led to a click on a cited source, in Pew’s March 2025 browsing panel of 900 US adults.
  2. Wikipedia, among the sources AI Overviews cite most, lost about 5% of its English search traffic, and the study’s authors found citations did not offset the decline.
  3. An AI Overview cites a median of 8 sources, but a desktop screen shows only about three before the reader clicks “Show all”.
  4. 29.8% of the domains AI Overviews cite do not appear anywhere on the first page of results, so a citation and a ranking are separate wins (Xu and colleagues, 2026).
  5. Discussion content is the exception: Reddit communities that AI Overviews can cite gained 12.0% more daily comments.

How often do people click the sources in an AI Overview?

Rarely: about 1% of visits to an AI Overview page led to a click on a cited source.

Chapekis, Lieb, Shah and Smith (opens in a new tab) at Pew Research Center tracked the browsing of 900 US adults through March 2025. For every Google search with an AI Overview, they checked whether the next page the person visited was one of the sources the summary cited. Just 1% of visits ended that way.

Compare that with the clicks AI Overviews take away. On pages without an AI Overview, people clicked a regular result on 15% of visits. On pages with one, they clicked a regular result on 8% of visits. Adding the 1% of citation clicks to those 8% still leaves the total well short of the 15% seen without a summary.

Pew matched only the first three cited links, which is what a desktop screen showed at the time. Clicks on sources further down the list would not be counted, so the true figure may be slightly higher. We look at the last row of the table in whether AI Overviews end browsing sessions.

Did being cited protect Wikipedia’s traffic?

No: Wikipedia is heavily cited by AI Overviews and still lost search traffic after they launched.

Khosravi and Yoganarasimhan (opens in a new tab) compared English Wikipedia articles with the same articles in German and French during 2024, when only US users had AI Overviews by default. English search traffic fell about 5.45% relative to German and 4.82% relative to French: roughly 100.27 million fewer search visits a month. It is a clear case of Google design changes moving traffic that publishers cannot control.

The authors address citations directly: they may send some users to Wikipedia, “but our estimates indicate that any resulting traffic did not offset the average decline.” Wikipedia is cited unusually often. Huang and colleagues (opens in a new tab) found Wikipedia cited for 28% of the queries they ran through AI Overviews, more than any other domain. A business site cited far less often has less reason to expect a better result.

Wikipedia carries no ads, so its loss is attention, not income. To show the stakes for others, the authors estimate that an ad-supported site losing the same traffic would forgo roughly $0.901M to $3.090M of ad revenue a month.

Why do citations send so few visitors?

Most citations sit out of sight, and the summary has often answered the question already.

Xu, Iqbal and Montgomery (opens in a new tab) collected 7,583 AI Overviews in spring 2026. They cited a median of 8 sources each, with up to 32. But Google shows only the first three on a desktop screen, and on a phone the sources may not appear until the reader taps “Show more”, as the Pew team notes. Most cited sites are therefore listed where few people look.

Being listed is also not the same as supplying the answer. Huang and colleagues measured how much of each cited page made it into the summary. In the answers they analyzed, AI Overviews cited nearly twice as many sources as ChatGPT search, 5.0 against 2.7 on average, but drew less content from each. Forum pages such as Reddit and Quora were cited, yet were under-represented in the summaries by 22.1 percentage points.

Placement among the citations matters too. In our study of AI Overview citations, the first organic result was cited in 49.5% of AI Overviews. YouTube was cited in 64.2%, mostly with videos that did not rank on page one.

Is a citation worth anything without the click?

Possibly, for visibility and credibility, but no study we reviewed measures its business value.

A citation can put a site in front of searchers it would not otherwise reach. Xu and colleagues found that 29.8% of the domains AI Overviews cited did not appear anywhere on the first page of results. In our own study, only 28.7% of AI Overview citations were page-one organic results for the same search.

Citations also shape trust. In a randomized experiment, Li and Aral (opens in a new tab) found that adding reference links made people trust AI search answers more, even when the links were wrong. That is a reason to care what the summary says about you, not evidence that a citation brings customers.

Accuracy is a real issue. Xu and colleagues checked 98,020 individual claims in AI Overviews against the pages cited for them, and 11.0% were not supported by those pages. Being cited does not guarantee being quoted correctly.

Which sites do gain from being surfaced?

Opinion, advice and experience content can gain; factual content mostly loses.

Zhang, Cui and Zhang (opens in a new tab) compared Reddit communities that AI Overviews can cite with adult communities Google keeps out of them. After AI Overviews expanded in August 2024, the citable communities gained 12.0% more daily comments and 12.4% more daily commenters. The effect was 2.3 to 2.8 times larger for experience-based communities than for fact-based ones.

The authors’ explanation: a summary cannot replace a discussion, so it works like an advertisement for it. A summary can replace a fact. The gain is also fragile. After Google’s conversational AI Mode rolled out globally in 2025, the extra gain for experience communities fell by 59% in commenters and vanished for comments.

What should you do about it?

Track citations and clicks as two separate numbers, and do not count one as a substitute for the other.

  1. Report AI Overview citations as a visibility measure, not a traffic measure. On the Pew evidence, about 1 visit in 100 to an AI Overview page becomes a click on a cited source.
  2. Keep traffic forecasts honest. If informational searches now show AI Overviews, plan for fewer clicks even if your citation count rises.
  3. Check what AI Overviews say about your business, since 11.0% of claims in one large study were not supported by the cited pages.
  4. Invest in content a summary cannot replace: firsthand experience, tools, data and discussion that people need to see in full.
  5. Watch AI Mode, which removed much of the gain discussion communities had won from AI Overviews.

What does the research not tell us yet?

The research shows citations send few clicks, but not what else a citation is worth.

  • The Pew data is from March 2025 and matched only the first three cited links on desktop.
  • No study we reviewed measures whether a citation leads to later brand searches, direct visits or sales.
  • The Wikipedia result covers one nonprofit publisher in 2024.
  • The Reddit result measures comments and commenters, not visits to commercial sites.
  • No study tests whether appearing among the first three citations earns more clicks than appearing lower.

Frequently asked questions

Do people click on links in Google AI Overviews?

Rarely. In Pew’s March 2025 panel of 900 US adults, just 1% of visits to pages with an AI Overview led to a click on a cited source.

Is being cited in an AI Overview the same as ranking on Google?

No. In our study, only 28.7% of AI Overview citations were page-one organic results for the same search, so the two are related but separate.

How many sources does an AI Overview cite?

A median of 8, in a 2026 study of 7,583 AI Overviews by Xu and colleagues. A desktop screen shows about three of them before the reader expands the list.

Should I stop Google from using my pages in AI Overviews?

Only with care. During spring 2026, the main controls that kept pages out of AI Overviews, such as “nosnippet”, also affected normal search results, according to Xu and colleagues.
