Google AI Overviews Reduced Organic CTR By Up To 64%

Google’s AI Overviews are changing search faster than most businesses expected.

For years, SEO operated on a relatively simple formula: rank highly, earn clicks and grow traffic. But AI-generated search summaries are beginning to disrupt that model at scale.

Recent studies now suggest Google AI Overviews can reduce organic click-through rates by anywhere from 15% to more than 60%, depending on the query type, industry and SERP layout. Some publishers and SEO studies have reported drops as high as 64% for certain informational searches. (Forbes, Search Engine Land)

At first glance, the trend looks alarming. Less traffic. Fewer clicks. Reduced visibility.

But underneath those declining click numbers, another shift is happening at the same time. The users who do click are often arriving with much stronger intent than before.

That distinction matters more than most businesses realise.

AI Overviews are changing the economics of search

Google AI Overviews fundamentally change how users interact with search results. Instead of displaying only blue links, Google increasingly generates AI-written summaries directly at the top of the results page. Users can often get answers, comparisons and explanations without visiting multiple websites.

That changes user behaviour immediately.

Instead of:

search → click → research → compare

the journey increasingly becomes:

search → receive summary → click only if necessary

This is one reason click-through rates are falling so sharply.

A large Seer Interactive study covering more than 25 million organic impressions found that organic CTR for queries containing AI Overviews dropped from 1.76% to 0.61%, representing a decline of roughly 61%. (Seer Interactive, Search Engine Land)

Forbes also summarised multiple industry studies suggesting AI Overviews may reduce organic traffic by between 15% and 64% depending on the search category. (Forbes)

The trend is becoming difficult to ignore.

Why users are clicking less

The reason is fairly straightforward. AI Overviews increasingly answer informational questions directly inside Google itself.

Users no longer need to open several websites just to understand definitions, product comparisons, recommendations or basic research questions. Google is effectively compressing the early-stage research process into the search results page itself.

That creates what many marketers now call the “zero-click” search environment.

According to Bain & Company, around 60% of searches already end without the user progressing to another website. AI-generated summaries are accelerating that behaviour further. (Bain & Company)

This is especially true for informational content, where the AI summary often satisfies the query immediately.

Publishers are already feeling the impact

Media companies and publishers have been among the first industries to experience the consequences directly.

A Reuters Institute report covered by The Guardian found publishers expect search traffic to decline substantially over the next few years because of AI summaries and chatbot-based discovery. Some organisations are already seeing dramatic reductions in click-through traffic on AI-heavy queries. (The Guardian)

The report referenced cases where publishers experienced CTR declines approaching 80% when AI summaries appeared above their links.

Other traffic analyses found major news websites suffering double-digit traffic losses following Google’s AI rollout. SimilarWeb data cited by the New York Post showed traffic declines of up to 40% for some major publishers after AI Overviews expanded. (New York Post)

This is why so many publishers now view AI search as both an opportunity and a threat simultaneously.

But fewer clicks does not automatically mean worse business outcomes

This is where the conversation becomes more nuanced.

Traffic volume and business value are not always the same thing.

One of the most interesting trends emerging from AI search research is that AI-referred visitors may convert significantly better than traditional organic traffic.

Several 2025 and 2026 benchmark studies suggest visitors arriving through AI search experiences often demonstrate stronger commercial intent because the AI has already handled much of the educational process beforehand.

Research highlighted by Searchless.ai and MarTech found AI-referred users converting around 4.4x better than traditional organic visitors in measured B2B datasets. (Searchless.ai, MarTech)

That does not mean every AI visitor converts better. But it does suggest AI search changes when users click and why they click.

AI systems increasingly pre-qualify the visitor

Traditional search often sends users into a research journey. AI search increasingly completes part of that journey before the click ever happens.

The AI handles comparisons, explanations, recommendation filtering and shortlist generation before directing users toward a source. That means the user arriving on the website may already be more informed, more confident and much closer to a decision.

Adobe Analytics found visitors arriving from generative AI sources showed lower bounce rates, stronger engagement and longer session behaviour compared to many traditional traffic sources. (Adobe, The Verge)

That suggests AI systems are increasingly acting as recommendation and qualification layers before the website interaction even begins.

Websites are no longer the first stage of discovery

This may be the biggest strategic shift happening right now.

For years, websites were responsible for early-stage education. Businesses created blog content, guides and SEO pages to explain products and build trust before conversion.

AI systems increasingly absorb that role.

The website increasingly becomes a validation layer and conversion environment after the AI has already shaped the customer’s understanding. This changes how SEO success should be measured.

Because if AI systems increasingly influence the decision before the user visits your site, then traffic volume becomes only one part of the equation.

AI Overviews are also changing visibility itself

Another major shift is happening underneath the surface.

AI Overviews do not simply mirror Google’s traditional ranking system. Research published in 2026 found AI-generated search systems often retrieve and surface substantially different sources compared to traditional organic rankings. (arXiv)

Another large-scale study found nearly 30% of domains cited inside AI Overviews did not appear in the visible first-page search results at all. (arXiv)

That changes the visibility game entirely.

Brands can rank strongly in Google and still remain largely invisible inside AI-generated answers. At the same time, smaller niche sites or community platforms may suddenly gain disproportionate visibility through AI citations.

This is one reason Reddit, Quora and forums increasingly appear inside AI-generated summaries.

The rise of recommendation visibility

Traditional SEO focused heavily on rankings and clicks. AI search introduces something new: recommendation visibility.

The key question is no longer only:

Do we rank?

Increasingly, the question becomes:

Does the AI mention us at all?

Because AI systems increasingly shape brand awareness, trust, product consideration and buying journeys before users ever reach a website.

That is why Generative Engine Optimisation, or GEO, is growing so quickly. Businesses increasingly need to optimise for citation visibility, topical authority, entity trust and structured content, not just rankings alone.

The future of search may involve fewer clicks, but stronger intent

The biggest mistake businesses can make right now is assuming lower traffic automatically means weaker performance.

AI search is absolutely reducing click-through rates in many categories. The data is becoming increasingly clear on that point.

But it is also changing the quality of the clicks that remain.

Users increasingly arrive later in the buying journey, more informed and more pre-qualified than traditional organic visitors.

That may ultimately create a smaller but commercially stronger search ecosystem.

Less browsing. More intent. Fewer clicks. Better-qualified visitors.

The businesses that adapt earliest to that shift will likely stop measuring success purely through traffic volume and start measuring visibility inside the AI discovery layer itself.

Because increasingly, the AI interaction is the early-stage customer journey. And by the time users finally reach your website, much of the decision-making may already be complete.
