New data shows Google’s AI Overviews now appear in 43% of searches, up from just 15% a year ago, a rapid shift toward AI-generated answers as the default way people find information online. AI Mode visits have more than doubled too. The change is reshaping how the web works, and it’s hitting publishers hard.

Key Takeaways

• Google AI Overviews now appear in 43% of searches, up from 15%
• AI Mode visits rose from 126 million to 279 million in a year
• Users are searching with longer, more conversational queries
• Publishers are losing referral traffic as clicks decline
• Google itself is increasingly the destination, not a gateway

What the Data Shows

The jump is steep. In just a year, Google’s AI-generated answers in search, known as AI Overviews, went from appearing in 15% of searches to 43%, according to a new report, driving a shift in how web users consume information.

The source is a market intelligence firm. Similarweb, which produced the analysis, noted that what began as an AI layer on top of search has become an integral part of the search journey itself.

The conversational side is surging too. During the same period, AI Mode visits rose from 126 million in June 2025 to 279 million by May 2026, as Google drops users into AI Overviews and then lets them continue researching in its more conversational AI Mode.

From Blue Links to Destination

The data captures a fundamental change. It illustrates a shift from an era when Google provided a simple list of blue links to click through, to one in which Google itself is the destination, sourcing its answers from the websites it once merely pointed to.

That keeps users on Google longer. The change appears to increase the time people spend on Google’s platform rather than using it only as a tool to discover other websites, turning search into a place you stay rather than pass through.

How people search is changing with it. Similarweb’s data shows the average length of Google searches has risen over the past year, suggesting users are replacing short keyword queries with longer, more natural conversational ones designed for AI.

The Toll on Publishers

The shift has a clear loser. The change has not been welcomed by publishers, who are losing out on referral traffic as AI citations increasingly answer questions without generating clicks.

News sites have been hit hardest. Similarweb previously reported on this trend, noting how devastating the decline in click-throughs has been for news publishers in particular, whose business models depend on search traffic.

The core tension is stark. Google’s AI answers are built from the work of the websites it summarizes, yet those same summaries can remove the reader’s reason to visit the source, cutting off the traffic and revenue that made the content possible.

The Fightback

Publishers aren’t standing still. Tech infrastructure company Cloudflare recently introduced tools that let publishers block AI crawlers from their sites unless the AI companies meet certain conditions.

It’s a leverage play. By gating access to their content, publishers are trying to force AI firms to negotiate, whether over payment or attribution, rather than freely scraping material that then competes with the original.

The pressure is mounting industry-wide. The move reflects a growing willingness among content creators to push back against AI systems that repackage their work, part of a broader reckoning over who benefits from the AI search era.

The Bigger Push Toward AI Search

Google has been steering users this way for months. The company has repeatedly signaled that AI-first search is its long-term direction, expanding access to AI Mode and folding AI answers deeper into the core search experience.

It has also flirted with going further. Earlier this year, a test flag briefly made AI Mode the default in a Chrome preview build before Google clarified it was an error and said it had no immediate plans to make AI Mode the default, an episode that showed both the direction and the sensitivity around it.

The momentum is unmistakable regardless. Whether or not AI Mode formally becomes the default, the Similarweb data shows AI answers are already becoming the default experience in practice, appearing in nearly half of all searches.

Why It Matters

This is a structural change to how the web works. For two decades, the open web ran on a simple bargain, Google sent traffic to sites in exchange for indexing them, and AI search quietly rewrites that deal by keeping users on Google.

The stakes are highest for the information ecosystem. If the sites that produce original reporting and research lose the traffic that funds them, the quality of the very content AI answers depend on could erode, a long-term risk buried inside a short-term convenience.

For users, it’s a trade worth understanding. AI answers are faster and increasingly capable, but the shift concentrates power in Google’s hands and reshapes who gets seen and paid online. As AI search becomes the default whether people choose it or not, the debate over attribution, payment, and control is only going to intensify.
