Google’s AI search is rapidly becoming the default, new data shows

Google's artificial intelligence-powered search feature, known as AI Overviews, is increasingly dominating user interactions on the search engine, according to new data released by market intelligence firm Similarweb. The findings indicate that AI-generated answers now appear in 43% of searches, up from 15% a year ago. This rapid adoption marks a fundamental shift in how users engage with search engines, transforming Google from a mere directory of web pages into a primary source of information. The transition has been swift, with AI Overviews evolving from an optional enhancement to a central component of the search experience. Users are now being directed directly into AI Overviews, where they can explore information through Google's more interactive AI Mode. According to Similarweb, the number of visits to AI Mode increased significantly, rising from 126 million in June 2025 to 279 million by May 2026. This evolution reflects a broader transformation in user behavior, moving away from traditional keyword-based searches toward more complex, conversational queries tailored for AI systems. Data from Similarweb indicates that the average duration of Google searches has increased, suggesting users are spending more time interacting with the search engine rather than simply clicking through to external websites. Publishers have expressed concern over the implications of this shift. With AI Overviews providing direct answers, there is less incentive for users to visit linked websites, resulting in reduced referral traffic. This issue has been particularly acute for news publishers, who rely heavily on search traffic for visibility and revenue. In response, tech infrastructure provider Cloudflare has developed tools enabling publishers to block AI crawlers unless compensation is provided through its marketplace. Despite these concerns, there is some optimism among publishers regarding the potential for improvement. Recent updates to AI search features have led to an increase in user engagement with traditional blue links within AI-driven search results. For instance, following a May 7 search update, the percentage of ChatGPT desktop queries leading to webpage visits doubled, increasing from 25% in March 2026 to nearly 60% by late May 2026. However, the overall trend continues to favor AI search dominance. While the inclusion of citations in AI responses has grown substantially, rising more than fivefold in the past year, only 6.8% of U.S. ChatGPT desktop queries included citations as of May 2026. Certain sectors, such as travel, retail, and sports, show higher rates of cited responses compared to other areas. The integration of AI into core search functions represents a major shift in digital interaction patterns. As users adapt to more conversational interfaces, the role of search engines is expanding beyond mere navigation tools. This evolution raises questions about the future of web traffic distribution and the sustainability of current business models reliant on referral traffic. As the influence of AI search grows, stakeholders across the digital ecosystem will need to navigate the changing landscape. Publishers must find ways to maintain relevance while adapting to new user behaviors, and technology providers will continue to refine their offerings to meet evolving demands. The ongoing interplay between innovation and adaptation will shape the trajectory of online information consumption in the coming years.
