Google's AI search goes mainstream: 43% of queries now show AI Overviews

Google's search product has undergone a structural shift in the past year. What began as an AI layer added to traditional search—blue links users would click to visit other websites—has become the primary interface itself. According to Similarweb, AI Overviews now dominate nearly half of all Google searches, and users are increasingly spending time on Google's platform rather than using it as a stepping stone to external content. This reflects both a change in user behavior (longer, conversational queries instead of short keyword strings) and a deliberate product redesign that makes Google's own answers the destination.

Publishers have suffered measurably from this shift. The loss of referral traffic—clicks that once drove readers from Google to news sites, retail sites, and other content—has been particularly damaging for news organizations. Yet the data also shows some room for recovery: citations in AI responses have risen more than fivefold in the past year, and when those citations are displayed prominently (as in ChatGPT's May 2026 update), users do click through. The May 7 search update that moved ChatGPT's web-page referral rate from 25% to nearly 60% by month's end suggests that visibility and design matter—but the larger trend remains: Google itself has become the answer, not merely the tool for finding answers elsewhere.
