October 2026 Update: What the Newer Data Shows
This article was first published on February 9, 2026. Since then, several larger studies — including the first randomized experiments on AI Overviews and AI Mode — have been released. The short version: the direction of the February findings holds, but the “accelerating” part does not. Zero-click searches are still rising and AI features still cost clicks, yet click-through on AI Overview queries partly recovered in early 2026, and the biggest new risk is AI Mode. The original February analysis below is kept unchanged as the historical record (apart from one corrected Ahrefs figure).
- 68% of US Google searches now end without a click. SparkToro's June 2026 analysis of Similarweb's US desktop and mobile clickstream panel found 68.01% of Google searches in January–April 2026 ended without any click, up from 60.45% in 2024. Only 0.34% of searches moved into AI Mode. Caveats: the 2024 and 2026 figures come from different panels, and searches inside the Google app are excluded, so Fishkin says the true rate is likely higher.
- CTR on AI Overview queries bottomed out and partly rebounded. Seer Interactive's April 2026 update (53 brands, 5.47M queries, 2.43B organic impressions) shows organic CTR on queries with an AI Overview fell from 3.19% in January 2025 to a low of 1.31% in December 2025, then recovered to 2.36% by February 2026. Queries without an AI Overview were at 3.82% in February 2026, so the gap remains large. Seer's conclusion: “The 2025 CTR decline did not extend into 2026.”
- Being cited still matters, but it doesn't close the gap. In the same Seer study, brands cited in an AI Overview earned about 120% more organic clicks per impression than uncited brands, yet still trailed informational queries with no AI Overview by 38%.
- A randomized experiment puts the causal hit at roughly 38%. In a working paper by Saharsh Agarwal and Ananya Sen (1,065 US desktop Chrome users, January–February 2026), AI Overviews appeared on 42% of queries; where they appeared, outbound organic clicks fell 38% and zero-click searches rose from 54% to 72%, according to Search Engine Journal's summary. The paper has not yet been peer reviewed.
- AI Mode cuts clicks far more than AI Overviews. A preregistered field experiment from the University of Pennsylvania and Northeastern (N=1,100, seven days, preprint posted August 18, 2026) found that routing all searches into AI Mode reduced click-through to external sites by 18.8 percentage points versus normal Google Search, and increased the share of users who also searched on Bing, DuckDuckGo, or Yahoo by 11.2 points. Hiding AI Overviews raised click-through by 8.8 points, even though the researchers' extension only managed to hide about 51% of them.
- Google's position: Google says AI Mode surpassed a billion monthly active users (May 2026) and, on its Q2 2026 earnings call, that it is “now sending billions of clicks to websites every week through AI features in Search.” Google has not published CTR data that would let anyone verify how that compares with pre-AI levels.
- Regulation moved from proposal to rule in the UK. On June 3, 2026 the CMA imposed a publisher conduct requirement on Google Search, requiring “effective controls over the use of their search content in generative AI.” Google is testing an opt-out from AI Overviews, AI Mode, and Discover with a limited group of UK sites, and has nine months to comply.
Does This Confirm or Change the February Picture?
It confirms the direction and changes the shape. No new study contradicts the finding that AI Overviews cost clicks, and overall zero-click behavior kept rising into 2026. We found no newer Ahrefs CTR study, so its 58% top-result figure remains its latest number; SparkToro was still citing it as “nearly 60%” in June 2026.
What changed: Seer's data shows the steep 2025 slide on AI Overview queries stalled and partly reversed in early 2026, so the February framing of an “accelerating” decline is not supported by the newer numbers. The randomized experiments, which isolate the effect of AI Overviews better than before-and-after comparisons, point to a click loss of roughly 38% where an AI Overview appears — still severe, but smaller than the 58%–61% observational estimates. And the 83% zero-click figure for AI Overview queries cited in February is higher than the 72% the Agarwal and Sen experiment measured.
The bigger story for the second half of 2026 is AI Mode: still a tiny share of searches in clickstream data, but growing fast by Google's own account and, in the one controlled test available, much more damaging to referral traffic than AI Overviews.
What Happened: The Numbers Behind the Zero-Click Surge
Zero-click search — where users get answers directly on Google without clicking through to any website — has hit a new high. According to updated Ahrefs research published in February 2026, AI Overviews now reduce click-through rates for the top-ranking result by 58%. That's nearly double the 34.5% reduction Ahrefs measured in April 2025 — an alarming acceleration in just eight months.
The Ahrefs study compared desktop CTR data from Google Search Console for December 2023 (before AI Overviews) against December 2025. For keywords triggering AI Overviews, average position-one CTR plummeted from 7.3% to just 1.6%, while informational keywords without an AI Overview only slipped from 7.6% to 3.9% over the same period. For a typical site ranking #1 on an AI Overview query, that's a roughly 78% collapse in the clicks that used to reliably arrive each month. (The 58% headline compares the 1.6% actual CTR with the roughly 3.7% Ahrefs expected without an AI Overview.)
But Ahrefs isn't alone. A Seer Interactive analysis of 25.1 million organic impressions across 42 organizations found an even steeper picture: organic CTR crashed 61% (from 1.76% to 0.61%) and paid CTR dropped 68% (from 19.7% to 6.34%) when AI Overviews appeared.
Meanwhile, a Pew Research Center study of 68,879 real queries found users clicked results only 8% of the time when AI summaries appeared, compared to 15% without them — a 46.7% relative drop. Only 1% of users clicked on sources cited within an AI Overview. And 26% of users left Google entirely after reading an AIO, versus 16% on traditional results.

Daily Google searches
Here's the paradox worth noting: Google search volume is actually growing. Google processes an estimated 13.6 billion searches per day in 2025, up from 8.5 billion in 2024. People are searching more than ever — they're just clicking less.
Why This Matters for SEO Professionals
The zero-click trend isn't new — SparkToro first reported in 2019 that over 50% of Google searches ended without a click. But AI Overviews have supercharged it. The critical shift is this: AI Overviews don't just reduce clicks on informational queries. They're expanding into commercial and transactional territory.
According to Semrush's analysis of over 10 million keywords, AI Overviews expanded from 6.49% of queries in January 2025 to over 25% by mid-2025. More concerning: commercial and transactional AI Overviews grew from 8.7% to 42.9% of AIO queries between January and October 2025. Google is no longer just answering informational questions — it's intercepting purchase-intent searches too.
Who's Affected
- Content publishers: Business Insider lost 55% of organic traffic; Forbes and HuffPost saw roughly 50% declines; Stereogum lost 70% of ad revenue and pivoted to paid subscriptions.
- Education and reference sites: Chegg reported a 49% decline in non-subscriber traffic and filed an antitrust lawsuit against Google, alleging AI Overviews “unjustly retained traffic.”
- Local businesses: Navigational AI Overviews grew from under 1% to over 10% of queries — Google is intercepting even brand-specific searches.
- Ecommerce: The shift to commercial AI Overviews means product discovery is increasingly happening inside Google without a click to the retailer.
The Mid-Funnel Black Hole
AI Overviews remove visibility into the user's research and comparison stage. As SEO veteran Michael Bonfils points out, marketers can no longer see the conversations users are having with AI during their decision-making process, making it harder to optimize content for the journey between awareness and purchase.
What the Experts Are Saying
The SEO industry is divided between alarm and pragmatic adaptation. Here's what leading voices are saying about the zero-click reality:
“Traffic is a vanity metric. It's not sales, nor is it necessarily tied to revenue. Your website influences the web more than it captures traffic from it.”
Fishkin's argument is grounded in data. HubSpot's organic traffic dropped 80% in 2025, yet their revenue and share price hit record highs. The audience found them through YouTube, LinkedIn, and brand awareness — not organic clicks. His framework: build “zero-click marketing” that delivers standalone value where audiences already are, rather than chasing clicks from Google.
“It does feel like AI Mode will be Google's default search experience sometime in the future. All the sources are removed from this view — so much for sending more traffic to publishers and content creators.”
Schwartz's concern centers on Google's AI Mode, where follow-up questions strip away source links entirely. As this becomes the default experience, even the small amount of referral traffic from AI Overviews could evaporate. His advice: “Keep doing what works. Write great content. Be useful. But build your audience. Don't depend on Google alone.”
“It wouldn't surprise me if 70% of the organic traffic that sites earned in 2024 is gone by 2026, leaving just 30% behind.”
Indig published the first-ever UX study of AI Overviews in May 2025, tracking 70 users across 400+ AIO encounters. His finding: most users only engage with the top third of the AI Overview panel. He also surfaced a stark stat — the scrape-to-human-visit ratio for AI platforms is staggering: OpenAI's is 179:1, Perplexity's is 369:1, and Anthropic's is 8,692:1, compared to Bing's 11:1.
“There's a bit of a disconnect between what is happening on the Search side and the AI Overview side — Google's Search goals often feel at odds with the impact of AI Overviews on site owners.”
Ray notes that Google still commands over 90.6% of global search market share, and AI platforms like ChatGPT and Perplexity account for less than 1% of global referral traffic. The existential threat to publishers isn't from ChatGPT — it's from Google's own AI features consuming the clicks that Google Search used to send outward.
Who's Being Hit Hardest: Industry-by-Industry Breakdown
AI Overviews are not affecting all industries equally. Semrush's analysis of over 10 million keywords reveals dramatic differences in AI Overview penetration across verticals:
Publisher Casualties
The impact on major publishers has been severe. UK tabloid Daily Mail reported CTR drops of up to 89% on queries affected by AI Overviews. Business Insider lost 55% of organic traffic and cut 21% of staff. CNN saw roughly a 30% year-over-year traffic decline. The AdExchanger investigation called it “the AI search reckoning” and suggested publishers “may never recover.”
The Ecommerce Expansion
What began as an informational-query phenomenon is now encroaching on commerce. In January 2025, 91.3% of queries triggering AI Overviews were informational. By October 2025, that share dropped to 57.1%, with commercial queries growing rapidly. Google is also placing ads alongside AI Overviews, with ad appearance rising from roughly 3% in January 2025 to over 40% by November.
Pro Tip
Finance, weather, and conversion queries already see near-100% zero-click rates because Google's built-in tools handle them directly. If your traffic depends on these query types, diversification isn't optional — it's urgent.
How to Adapt: 7 Strategies That Actually Work
Zero-click search isn't something you can reverse. But you can adapt. Here are seven data-backed strategies from industry research and expert recommendations:
1. Optimize for AI Citation, Not Just Rankings
Here's the counterintuitive finding: Seer Interactive found that brands cited in AI Overviews earn 35% more organic clicks and 91% more paid clicks compared to uncited brands. Being inside the AI Overview actually helps you. Structure content with clear, direct answers in the first 40-60 words of each section, use H2/H3 headings that mirror user queries, and add FAQ schema and structured data.
Pro Tip
Place a concise 'answer capsule' — a direct 1-2 sentence answer — immediately after each question-style heading. Research shows 72.4% of ChatGPT-cited posts include one, and the same principle applies to Google AI Overviews.
2. Build Brand Entity Authority
AI search systems in 2026 rank entities, not just URLs. Build citation history, develop authoritative backlink profiles, and earn brand mentions across the web. Control how AI describes your brand by ensuring consistent brand descriptions across all platforms. Wikipedia, YouTube, and Reddit are the three most-cited sources in AI Overviews according to Pew Research — getting your brand referenced on these platforms feeds AI visibility.
3. Create What AI Cannot: Interactive Tools and Original Research
AI Overviews can summarize information, but they can't replace interactive experiences. Free tools, calculators, configurators, and gated resources draw clicks even when AI answers dominate the SERP. Original research and first-party data are especially valuable because AI systems cite them as primary sources. If you can generate proprietary data, you become the source rather than the summarized.

4. Shift Metrics from Traffic to Visibility
Traditional traffic metrics are becoming less reliable indicators of brand health. Track branded search volume as a proxy for awareness generated by zero-click impressions. Monitor your AI citation frequency and share of voice across AI platforms. New metrics like “AI Presence Rate” and “Share of AI Conversation” are emerging as the leading indicators of 2026.
Check how AI search platforms present results for your target keywords using our AI Overview Analyzer to understand your current AI visibility baseline.
5. Diversify Beyond Google
Google still handles the majority of search, but putting all your eggs in one basket is increasingly risky. Build presence on YouTube, LinkedIn, and Reddit — the three platforms most frequently cited in AI Overviews. Optimize for ChatGPT, Perplexity, and Gemini in addition to Google. Community engagement in forums and social platforms creates traffic sources that AI cannot disintermediate.
6. Target Bottom-of-Funnel Keywords
While informational queries are being consumed by AI Overviews, high-intent commercial and transactional keywords still generate clicks — for now. Prioritize content that targets users closer to a purchase decision. Use our Keyword Search Volume Checker to identify high-intent keywords where organic clicks remain strong.
7. Add Structured Data and FAQ Schema
Structured data helps AI systems understand and cite your content more effectively. FAQ schema, HowTo markup, and Article schema give search engines clean, extractable information to feature in AI Overviews and rich results. Generate valid FAQ markup quickly with our free FAQ Schema Generator.
Don't Panic-Pivot
Some sites are making drastic changes — gating all content, blocking AI crawlers, or abandoning SEO entirely. The data doesn't support these extremes. Sites cited in AI Overviews still earn more clicks than uncited sites. The right approach is measured adaptation, not scorched earth.

What to Expect Next
The trajectory is clear, even if the exact timeline is uncertain. Gartner predicts traditional search engine volume will drop 25% by 2026 due to AI chatbots, with organic search traffic to websites declining 50% or more by 2028. Semrush forecasts AI-powered search could overtake traditional search traffic by the first half of 2028.
Regulation is also in play. The UK's CMA has proposed rules forcing Google to offer publisher opt-outs from AI Overviews, with a consultation period running until February 25, 2026. If enacted, this could fragment the AI Overview experience and potentially reduce its coverage. Google has said it's “exploring updates” to its controls but has offered no timeline.
October 2026 update: the rules were enacted. The CMA imposed the publisher conduct requirement on June 3, 2026, and Google is testing an opt-out covering AI Overviews, AI Mode, and Discover with a limited group of UK site owners, with a nine-month compliance window. Meanwhile, Google says its AI features are driving search queries up, not down: on the Q2 2026 earnings call, Sundar Pichai said AI Mode is “driving an incremental increase in Search queries overall,” which cuts against Gartner's forecast of a 25% drop in search volume by 2026.
There's a silver lining in the data. Ahrefs reports that AI search visitors convert 23x higher than regular search visitors. Semrush data shows AI-driven traffic achieves a 4.4x higher conversion rate than traditional organic. Fewer clicks — but dramatically higher quality. The businesses that optimize for AI citation now will be positioned to capture disproportionate value as this shift accelerates.
As RankScience advises: start your AI optimization in early-to-mid 2026 and spend 6-12 months building visibility. By mid-2027, the early movers will have established dominant positions in AI results that latecomers will struggle to displace.
