Google AI Overviews are killing organic CTR — and the numbers are no longer a warning sign. They’re a verdict.

Seer Interactive tracked 3,119 informational queries across 42 organizations and 25.1 million organic impressions from June 2024 to September 2025. When a Google AI Overview appeared on the page, organic click-through rates dropped from 1.76% to 0.61%. That’s a 61% collapse. Not a dip. Not a soft patch. A structural change in how search works.

What the Google AI Overviews CTR Drop Actually Shows

The Seer study is the most rigorous analysis on this question so far, and its findings should shake anyone running an SEO-dependent business.

A 61% organic CTR drop is the headline number. But the detail that really stings is this: even queries without an AI Overview saw organic CTR fall 41% over the same period. Google’s shift toward answer-on-page is repricing every position in the SERP — not just the ones where an AI Overview lands above the fold. The presence of AI answers is changing how users interact with search results pages even when no AI Overview actually appears.

Paid search didn’t escape either. Paid CTR on AI Overview queries dropped 68%. More than organic. That’s a counterintuitive finding that most coverage buries, but it matters: if even advertisers are losing clicks when AI Overviews appear, the old logic of “I’ll just buy traffic around this” starts breaking down.

So Google answers the question, the user reads it, and nobody clicks. That’s the loop. It’s functioning exactly as designed.

The HubSpot Search Traffic Collapse: What the Real Numbers Look Like

HubSpot is the clearest large-scale example anyone can point to, partly because CEO Yamini Rangan talked about it openly on an earnings call instead of burying it in footnotes.

Between November and December 2024, HubSpot’s organic traffic fell from 13.5 million monthly visits to 8.6 million — nearly 5 million visits gone in 30 days. By Q2 2025, they’d shed somewhere between 70% and 80% of their organic search traffic from peak. On that Q1 2025 earnings call, Rangan told analysts directly: “AI Overviews are giving answers, and fewer people are clicking through to websites.” No spin. She named the mechanism.

Here’s what’s easy to miss: HubSpot’s rankings didn’t collapse. Their positions held. The traffic disappeared anyway because Google was answering above the fold before users had any reason to scroll down to the actual results.

Position one no longer means what it used to mean. You can own the top result and still lose the visit.

This is the new math of organic search. It’s not about ranking. It’s about whether Google decides your topic gets an AI Overview — and whether you’re cited inside it when it does.

Zero-Click Search Impact: Why This Isn’t a Fringe Effect

The phrase “zero-click search” has been floating around SEO circles since at least 2019. For years it felt like a slow-moving trend, something worth monitoring but not urgent. It isn’t slow anymore.

Ahrefs published an updated study in February 2026 tracking 300,000 keywords. Their finding: CTR at position one drops 58% when an AI Overview is present. That lines up closely with Seer’s 61% figure across a completely different methodology and dataset. Two independent studies converging on the same ballpark number is hard to dismiss as sampling error or methodology artifact.

The industry-wide signal matches. The median publisher saw a 10% year-over-year organic traffic decline in the first half of 2025. Non-news content sites dropped 14%. Those are averages — which means plenty of publishers fell considerably harder.

And then there’s the consumer response. DuckDuckGo reported a 30% surge in app installs and a 28% jump in site visits in the single week following Google I/O 2026. That spike didn’t happen because millions of people suddenly cared about privacy philosophy. It happened because ordinary users opened Google, got an AI-generated answer they didn’t fully trust, and went looking for an alternative. That’s a measurable behavioral signal. It’s small relative to Google’s total volume, but it’s directional.

Why SERP Feature Optimization Is Now Table Stakes

One finding in the Seer data that most coverage glossed over: brands cited inside AI Overviews earn 35% more organic clicks and 91% more paid clicks compared to brands not cited.

Read that twice. Being cited in the overview that’s supposedly killing your traffic actually lifts your traffic — substantially.

So the new SEO game isn’t “rank in position one.” It’s “earn a citation in the AI Overview.” These are completely different tasks. Citation optimization means writing content built to be excerpted: clear definitions, direct answers to specific questions in the first two sentences under each heading, citable statistics with clear sourcing, and structured data markup that signals authoritative, extractable content to Google’s systems.

There’s a real tension in that approach that’s worth naming honestly. You’re optimizing to appear inside a feature that aggregates your content and reduces the need to visit your site. But the alternative — ignoring AI Overview optimization entirely — means your competitors earn the citation and the 35% traffic lift while you earn nothing. The imperfect play beats the passive one.

The DuckDuckGo Surge and What User Behavior Actually Signals

The DuckDuckGo install spike is worth pausing on because it reveals something about user psychology that SEO analysis typically ignores.

A 30% jump in weekly installs isn’t a privacy-advocacy story. It’s an experience story. People opened Google, got an AI-generated block of text in response to a question they cared about, and felt something was off — either the answer was too generic, too confident about something uncertain, or just not what they came for. So they went somewhere else. That’s the signal underneath the DuckDuckGo number.

But I’d push back on the interpretation that this represents a durable competitive shift away from Google. The distribution reality is brutal: Google is the default on virtually every Android device sold globally, and it’s the default in Safari on iPhone. Most users don’t change defaults. The real competitive pressure on Google right now isn’t DuckDuckGo or Bing. It’s AI chatbots. ChatGPT with web search, Perplexity, and similar tools are all targeting the same informational queries that AI Overviews handle — and those products have the novelty, the interface, and the direct-answer experience that users seem to want.

Google may be losing to itself. AI Mode cannibalizes AI Overviews, which cannibalizes organic results, and the whole stack reduces the number of outbound links users follow in any given session.

How to Adapt Your SEO Strategy Right Now

Adapting to organic CTR loss from AI Overviews means rethinking what successful content actually is. A few specific approaches that are showing traction:

• Target long-tail queries too specific for AI Overviews to answer cleanly. Overviews handle broad informational questions well. Highly situational queries — ones involving specific numbers, uncommon product combinations, or niche comparisons — are far less likely to trigger an AI Overview at all.
• Restructure existing pages for citation. Use tight H2 definitions. Answer questions directly in the first sentence under each heading. Produce original data that Google can reference rather than answer from scratch. If Google is going to excerpt your content, make the excerpt strong enough to pull curiosity clicks.
• Audit your AI Overview exposure. Tools including Semrush and Ahrefs now flag SERP features at the query level. Know which of your high-traffic pages are sitting below an AI Overview and treat those as your first restructuring priority.
• Build owned channels in parallel. Organic search as top-of-funnel acquisition is structurally weaker than it was in 2022. Email lists, newsletters, and community channels are less exposed to SERP feature volatility. Companies that spent 2023 and 2024 building those assets are in a far more stable position than businesses that ran purely on SEO volume.

February 2026 data showed a slight organic CTR rebound on AI Overview queries — from 1.3% in December 2025 to 2.4% in February 2026. That’s mildly encouraging. But 2.4% against a mid-2024 baseline of 1.76% suggests the floor shifted permanently rather than temporarily. Anyone treating that rebound as a signal to stand pat is reading the wrong chart.

The search traffic collapse from Google AI Overviews is real. Organic CTR fell 61% across 25 million impressions in the Seer study. Ahrefs confirmed the scale independently. HubSpot lost 70% of its organic traffic with its rankings intact. The mechanism isn’t a mystery — Google is answering before anyone clicks. The content teams that restructure for citations and diversify their channels in 2026 will be the ones with stable audience relationships by 2027.
