Google’s AI Search Is Rapidly Becoming the Default, New Data Shows

Google’s AI-powered search experience is rapidly becoming a standard part of how people find information online, with new data showing the company’s AI-generated answers appearing in a growing share of searches.

Google AI Overviews appeared in 43% of searches during the latest measurement period, up from just 15% a year earlier, according to a new analysis from market intelligence firm Similarweb.

The increase suggests Google’s AI features are evolving from an additional layer on top of traditional search into a central part of the search experience. Users who encounter an AI Overview can also continue researching through Google’s conversational AI Mode rather than leaving Google for another website.

AI Mode is growing quickly as well. Similarweb reported visits increased from 126 million in June 2025 to 279 million by May 2026.

Google is becoming the destination.

The shift represents a significant departure from the traditional Google Search model, where users entered keywords and received a list of links directing them to websites. AI-powered search increasingly allows Google to provide the information itself by generating responses based on sources from across the web. Similarweb’s data also indicates people are spending longer searching on Google. Search queries are becoming longer and more conversational as users move away from short combinations of keywords toward questions designed for AI-powered interfaces.

For publishers, however, the transition creates significant challenges. AI-generated answers can provide information without requiring users to visit the websites that originally published it, potentially reducing referral traffic.

The impact has been particularly concerning for news publishers. Cloudflare has responded to the broader AI crawling trend by introducing tools that allow website operators to block AI crawlers unless companies pay for access through its marketplace.

AI citations increase, but clicks remain limited.

Similarweb found that the number of AI responses containing citations has increased more than fivefold over the past year. However, citations remain relatively uncommon on some AI platforms. As of May 2026, only 6.8% of U.S. desktop ChatGPT queries included citations, although categories including travel, retail and sports generated cited responses more frequently.

There are signs that AI-driven search could still generate meaningful traffic for publishers. Similarweb found that U.S. desktop referrals from ChatGPT improved following a May 7 search update. The proportion of visits reaching external webpages increased from about 25% in March to nearly 60% by May 30.

The increase suggests users are more willing to visit sources when prominent links are included alongside AI-generated answers.

Even with those improvements, the broader direction of search remains clear. As Google expands AI Overviews and AI Mode, its search engine is increasingly shifting from a gateway that sends users across the web into a destination where users can research topics without leaving Google’s ecosystem.
