How AI Is Reshaping SEO in 2025
Key Facts:
Organic CTR fell 65% on queries where AI Overviews appeared in 2025.
Cited brands earn 35% more organic clicks than uncited brands nearby.
Only 16% of brands systematically track their AI search performance today.
Search still works. It just works differently now. Here's what actually changed, what the data shows, and what your business needs to do about it.
What Happened: Your Rankings Are Fine. Your Traffic Isn't.
This is the conversation I'm having with almost every marketing leader right now. Rankings look stable. Content is live. The agency report is green. And yet organic isn't converting the way it used to.
The SERP changed around your content without your content changing at all.
Google AI Overviews now sit at the top of results for a growing share of queries. Zero-click searches account for roughly 60% of all Google sessions, according to Bain research from February 2025. The user gets their answer. They don't click. Your ranking existed, and it generated nothing.
"I used to think ranking well was enough. Now I think ranking well is just the cover charge. Getting cited is the show."
The shift isn't uniform. If your business is in e-commerce or local services, the exposure is lower for now. If you're in B2B tech, health, education, or anything informational, AI Overviews are already your primary SERP challenge. Ahrefs November 2025 data shows AI Overviews appear in 99.9% of informational keywords. That's not a rounding error. That's essentially every query where someone is trying to learn something.
The brands that understand this are treating it as an opportunity. The ones that don't are going to keep publishing content and watching their traffic reports in quiet confusion.
The Data: What the Research Actually Shows
The Click-Through Numbers, Honestly
Seer Interactive tracked 3,119 informational search terms across 42 organizations and 25.1 million organic impressions from June 2024 to September 2025. Organic CTR on queries where an AI Overview appeared fell from 1.76% to 0.61%. That's a 65% decline.
But here's the number that gets less coverage: queries without AI Overviews saw organic CTR fall 41% over the same period, from 2.72% to 1.62%. The behavioral shift is happening across all of search, not just where AI Overviews appear. Users are resolving more of their search intent on the SERP itself and clicking through less, regardless of format.
By February 2026, organic CTR on AIO queries had rebounded from a December 2025 floor of 1.3% to 2.4%, per Seer Interactive's April 2026 update. The initial collapse was driven partly by a rapid surge in impressions. As AI Overviews normalized, click behavior recovered.

The Citation Advantage Is the Real Story
The most important data point isn't the CTR drop. It's what happens when you're cited inside the AI Overview.
Brands cited in AI Overviews earn 35% more organic clicks and 91% more paid clicks than non-cited brands on the same queries, per Seer Interactive's September 2025 analysis. Pew Research's July 2025 study of 68,879 actual Google searches from 900 US adults found that when a Google AI summary appears, users click an external link 8% of the time. Without a summary, that's 15%. When you're the cited source, you're in the 8%. Everyone else is fighting for scraps below it.
The other counterintuitive finding: 40% of AI Overview citations come from pages ranking below position 10, per Ahrefs 2025 data. Ranking position predicts citation less than content structure and authority signals do. A page ranking 12th can appear in the AI Overview while the page ranking 3rd sits invisible below it.
AI Overview click shifts by the numbers

The citation advantage extends beyond organic. Paid CTR also rises for brands appearing as AI Overview sources.

Ranking below position 10 does not disqualify you from being cited. Structure and authority matter more than position.

Google's AI doesn't cite randomly. It selects based on trust, structure, and entity verification. The pattern is consistent across multiple 2025 studies.
Branded web mentions have the strongest correlation (0.664) with AI Overview appearances, much higher than backlinks at 0.218, per Position Digital's 2026 analysis. The brands appearing in AI Overviews are known brands, not just linked brands. Being talked about in third-party press, community discussions, and industry publications predicts citation better than any on-page signal.
On the content side, structured formatting wins. Lists, tables, numbered steps, and direct answers in the first 100 words after each heading are what AI systems extract from. Dense narrative pages with no clear answer structure are harder to cite regardless of how well they rank.

Which Industries Are Most Exposed Right Now
Not every business faces the same level of disruption. The exposure map is clear, and knowing where you sit determines how urgently you need to act.
Health and education queries trigger AI Overviews 75 to 88% of the time. B2B tech is in the same range. These categories are already in a citation economy. Informational pages in these sectors are either sources or invisible.
E-commerce and local are more protected for now. Local searches trigger AI Overviews only 7.9% of the time, per Ahrefs November 2025 data. Shopping queries were at 3.2% for most of 2025. But Google showed AI Overviews on 14% of shopping queries by March 2026, a 5.6x increase from November 2024. The direction of travel is clear.
Content Quality Is Now a Binary Filter
Google's Helpful Content system was absorbed into core ranking in March 2024. Content written for search engines rather than people is now actively penalised, not just deprioritised. This is not new guidance. It's new enforcement.
Google's Information Gain patent (US Patent 20200349181A1, filed October 2018, granted June 2022) scores content from 0.00, fully redundant, to 1.00, fully novel. Content that restates what the top ten results already cover gets demoted systematically. Publishing thin AI content at volume is now a domain-level authority risk.
74.2% of new web pages contain AI-generated content, per Ahrefs' analysis of 900,000 pages from April 2025. Only 2.5% are fully AI-generated without human editing. Google's systems are getting better at identifying which pages add something the index doesn't already have. The ones that don't are drag on your domain's overall authority, not just individual pages.
E-E-A-T Is Enforced Algorithmically Now
Experience, Expertise, Authoritativeness, and Trustworthiness have been part of Google's quality guidelines since 2014. What changed in 2025 is enforcement. The signals are now verified algorithmically through cross-platform entity checks, not just assessed by human raters.
In practice, this means your author's byline is not enough. They need Person schema with verifiable credentials off your domain: LinkedIn, industry publications, speaker profiles. The sameAs link chain connecting their identity to external profiles is what builds the entity node Google needs to attribute expertise. A byline that links nowhere contributes nothing to your E-E-A-T footprint.
For your organisation as a whole, Organization schema with sameAs links to Wikipedia, Wikidata, LinkedIn, and Crunchbase tells Google who you are. Without this, Google cannot confidently attribute your content to a verified entity in its Knowledge Graph. Entity ambiguity is a citation disqualifier.
What This Means
What this means
Rankings are still real, but they are no longer sufficient. AI Overviews cover approximately 25 to 48% of tracked queries depending on methodology, and reach 2 billion monthly users. For informational queries, the AI answer is the first thing your customer sees. Whether your content is the cited source is the new optimization question.
The CTR drop is a bifurcation story, not a collapse story. Cited brands earn 35% more organic clicks and 91% more paid clicks than uncited brands on the same SERP. Getting cited is now worth more than holding position one without a citation on the same query.
The brands losing ground are producing content. The brands winning are producing authority. Volume is no longer a strategy. Original perspective, named expertise, structured formatting, and verified entity signals are what AI systems select from when building their answers.
What To Do: Five Actions You Can Start This Week
What to do next
Five moves that shift you from ranking to citation
Identify which target queries trigger AI Overviews
Run your top 50 keywords through Semrush, Ahrefs, or SE Ranking. Track AI Overview presence now. Split them into AIO-present and AIO-absent queries. For AIO-present queries, the goal shifts from ranking to citation. These need a different content approach than traditional SEO.
Restructure informational content for AI extractability
Every page targeting an AIO-present query should open with a direct 2 to 3 sentence answer to the main query. Use H2 headings phrased as questions. Put the answer in the first 100 words after each heading. Use bullet lists for comparisons and numbered steps for processes.
Build your author entity, not just your byline
Add Person schema to every author page with jobTitle, knowsAbout, and sameAs links to LinkedIn and external profiles where credentials are verifiable. Link every article’s author URL back to that profile page. A byline with no entity verification does nothing for your AI citation odds.
Audit your off-site brand presence
Branded mentions now correlate more strongly with AI Overview citations than backlinks do. Run a brand mention audit using Ahrefs, Semrush, or Brand24. Look for whether your brand is referenced in the context of the topics you want to own.
Set up AI citation tracking before you need it
Google Search Console does not natively show whether your impressions came from AIO-present SERPs. Tools including Semrush, SE Ranking, Profound, and BrightEdge can segment this. Setting this up now puts you ahead before a traffic drop forces the question.
