Google AI Overviews and SEO: Only 38% of Citations Now Come From the Top 10

Quick answer: Ahrefs found that about 38% of the URLs cited in Google AI Overviews also rank in the top 10, down from about 76% in July 2025. Rank alone no longer predicts who gets cited, so regulated-industry marketers need clear, accurate, original pages that an AI summary can pull from, not just a high position.

Google’s AI Overviews are changing how content is found and chosen. Ahrefs’ latest study shows far fewer cited pages come straight from the top 10 results than a year ago, and other studies show fewer clicks reaching source pages when an overview appears. For healthcare, finance, and legal marketers, where credibility and compliance are not optional, that means rethinking how content is structured, how authority is shown, and how success is measured.

Key Takeaways

• About 38% of URLs cited in AI Overviews also rank in the top 10, down from about 76% in July 2025 (Ahrefs).
• Studies put the click-through drop on queries with an AI Overview anywhere from about 15.5% to 61%, depending on the study (Amsive and Seer).
• Ahrefs reported position-1 click-through about 34.5% lower when an AI Overview is present (Ahrefs).
• Pew Research found that the browsing session ended on 26% of Google results pages with an AI summary, versus 16% of pages with only traditional results (Pew Research Center, July 2025).
• Citation no longer follows rank, so content clarity, accuracy, and answer-first structure matter more.

What the Drop From 76% to 38% Means

Ahrefs reports that about 38% of URLs cited in Google AI Overviews also appeared in the top 10 results for the query, compared with about 76% in July 2025. The study covered about 863,000 keyword SERPs and 4 million cited URLs from Ahrefs Brand Radar (Ahrefs). The link between organic rank and citation is much weaker than it was a year ago.

Why this matters for regulated industry SEO

For marketers in regulated fields, this means page rank alone is no longer a reliable sign of visibility. A healthcare law firm or financial advisory blog that ranks in the top 10 may still not be cited in an AI Overview. Content now has to rank well and also be structured so an AI summary can pull from it accurately.

In regulated industries, the accuracy of anything that gets quoted matters. Pages with clear definitions, plain answers, and verifiable sources are easier to cite correctly, and they lower the risk of a summary misrepresenting your content.

The Decline in Click-Through Rates (CTR) and Zero-Click Search Behavior

Pew Research Center data (March 2025 browsing data, published July 2025; 68,879 real Google searches from 900 U.S. adults), found that when an AI Overview appears, users click a traditional result in about 8% of visits, compared with 15% of visits when there is no overview. The browsing session ended on about 26% of results pages with an AI Overview, compared with 16% of pages without one. Only about 1% of searches led to a click on a link inside the overview itself.

Estimates of the click-through drop for top-ranking pages vary by study, from about 15.5% (Amsive, 700,000 keywords) to about 61% (Seer Interactive). Seer also reported organic CTR of 2.4% on queries with an AI Overview versus 3.8% on queries without one, a gap of about 37% (April 2026). The studies use different methods and query sets, so treat the range as a direction, not a precise figure.

In regulated industries such as healthcare and legal, where people often need to reach the source page to book, call, or read the full guidance, this shift matters. If someone reads an AI summary of your page and never visits it, the lead or the informed decision you wanted may never happen. Rankings alone no longer tell you how much traffic or influence you have, so track how your content is cited and summarized as well as how many clicks it gets.

How AI Overviews Are Changing the Relationship Between Organic Rank and Citations

Organic rank is no longer a direct stand-in for citation. In Ahrefs’ test of organic blue links, 37.1% of cited URLs ranked in the top 10, 26.2% ranked in positions 11 to 100, and 36.7% did not rank in the top 100 at all (Ahrefs). In plain terms, roughly 6 in 10 cited pages come from outside the top 10.

Previously, the top 10 results were the obvious pool for AI-generated summaries. Now Google draws from a wider set of pages. For marketers in healthcare, legal, or finance, that means being visible in search results is not a guaranteed path to being cited. The focus shifts to making content easy to extract, authoritative, and matched to the question the overview is trying to answer.

That means more than a high ranking. Content needs detail, context, and clear answers. In regulated fields, this has to be balanced with compliance guardrails so the content never overstates results or uses unverified information.

Citations Now Come From a Wider Mix of Sources

Ahrefs also found that among cited pages that do not rank in the top 100 for the query, 18.2% were YouTube URLs. YouTube was the most-cited domain in AI Overviews in its data. That tells marketers that video and other non-traditional formats can be pulled in alongside standard web pages.

Expanding the Content Audit Scope

In the past, SEO strategy for regulated sectors like healthcare and legal often focused on securing top-10 placements. That is no longer enough. A broader audit should look at which formats and sources show up for your topics, including video, and how they are framed.

Include source variety in your content plan. Look at how third-party content is structured, cited, and presented in AI Overviews for your key topics. In regulated fields, where tone, accuracy, and compliance matter, it helps to know how other sources shape what people read about your category. Tools like Ahrefs and Semrush can help show which sources are being cited and how they relate to your audience.

Impact of AI Overviews on Traffic for Cited Pages and Pages in the Top 10

Ahrefs reported that position-1 click-through was about 34.5% lower when an AI Overview is present (December 2025, 300,000 keywords), per Ahrefs. That is a click-through figure for the top result, not a measured traffic loss for every cited page. Being cited still appears to help: Seer reported that cited brands get about 120% more organic clicks per impression than uncited brands on informational queries (April 2026).

The gap between queries with and without AI Overviews means strategy has to plan for a new baseline in user behavior. A page can keep its ranking and still lose some of its traffic value, because fewer people click through. This is especially relevant in healthcare and legal, where users want detailed, authoritative information but may stop after reading the summary.

To respond, write pages that answer the question directly near the top, back claims with sources, and give people a reason to visit, such as a form, a booking step, or detail an overview cannot cover. Track citations and brand mentions alongside clicks.

User Behavior Shifts: From Clicking to Session Termination After AI Overviews

Pew’s data shows the search session ended on about 26% of results pages that showed an AI Overview, compared with 16% on results pages without one. That is a real change from the pre-overview pattern, where users more often followed links to check or expand on an answer. When the summary feels complete, there is less reason to keep searching.

For regulated industry marketers, this has practical implications. If users are less likely to visit after an overview cites your page, your content has to earn a place in the answer and be written so what gets pulled is accurate on its own. That means concise, high-value answers and clearly stated key terms and data points, with the caveats kept next to the claim.

• The session ends on about 26% of results pages with an AI Overview, versus 16% of pages without one (Pew Research Center).
• Users click a traditional result in about 8% of visits when an AI Overview appears, versus 15% of visits without one (same source).
• More sessions end without a click, so measure citations and brand visibility, not only traffic.

Adapting SEO Strategies to the New Baseline Set by AI Overviews

With about 6 in 10 cited URLs ranking outside the top 10, SEO strategy has to aim past traditional rankings. Rank alone does not ensure citation, so content should be built to be picked up directly by an AI summary, with clear answer-focused formatting and a presence on the sources people and AI systems trust.

Marketers in regulated industries, especially healthcare, legal, and finance, should check how their content reads when summarized. Audit current pages for clarity, neutrality, and fit with user intent. For example, a legal blog that clearly defines complex terms and gives actionable guidance may be easier to cite than one that assumes prior knowledge. Targeting specific, long-tail questions can also help capture searches where an overview appears.

• Re-evaluate content structure: Use clear headings, concise explanations, and sourced summaries so content is easy to quote accurately.
• Widen your presence: Publish useful material in more than one format, including video, on channels your audience already uses.
• Track performance beyond rankings: Use tools such as Ahrefs and Semrush to see where your content appears in AI Overviews and adjust.

Rankings still matter, but they no longer guarantee visibility in AI Overviews (Ahrefs).
