Google AI Overviews Expand Rapidly, Appearing in Nearly Half of Search Queries
The Google AI Overviews feature has recorded accelerated expansion across search results, with its visibility increasing by 58% year-on-year. It now appears in nearly half of all user queries, signaling a gradual transformation in the structure of the digital search experience.
Comparative data between February 2025 and February 2026 reveals widespread adoption across nine key sectors, including healthcare, enterprise technology, education, insurance, entertainment, travel, e-commerce, finance, and restaurants.
The education sector witnessed one of the sharpest increases, with AI-generated summaries appearing in 83% of queries, up from just 18% months earlier. Enterprise technology followed a similar trajectory, rising from 36% to 82%, while the restaurant sector expanded significantly from 10% to 78%.
Healthcare—already among the most AI-driven sectors—rose from 72% to 88%, reflecting growing user preference for conversational, simplified medical explanations rather than navigating multiple traditional links.
This trend coincides with the global surge in AI-powered tools used to answer health and professional questions. However, traditional organic search results still appear in approximately 52% of queries, indicating that search has not fully transitioned to an AI-first model. Instead, the ecosystem is currently divided between pages that begin with a generative summary and those that display only conventional ranked links, marking a transitional phase rather than a complete overhaul.
When AI Overviews are displayed, they significantly reshape the visual layout of search results. The generative summary block exceeds 1,200 pixels in average height, while the typical visible screen area on desktop devices measures around 900 pixels. This pushes the first organic result below the fold, granting the AI summary clear interactive priority.
Another notable shift is that the sources cited within AI Overviews do not necessarily align with the top ten organic results. Only about 17% of referenced sources overlap with the top-ranked links. This reflects the system’s use of multi-query retrieval techniques, analyzing multiple sub-queries to generate a single comprehensive response. As a result, the pool of content being surfaced expands beyond traditional ranking rules.
Current indicators do not signal a complete break from conventional search. Rather, they point to a steady expansion of AI-driven search experiences—particularly in high-value sectors such as healthcare and technology. While organic search retains a slight majority presence, user behavior is clearly shifting toward immediate answers and interactive discovery rather than link-based browsing alone.
