- Google's AI Overviews appeared in 43% of searches as of the Similarweb report, nearly tripling from 15% over the past year, while AI Mode visits grew from 126 million in June 2025 to 279 million by May 2026.
- Google search queries have lengthened over the past year, with users replacing short keyword-based queries with longer, more natural conversational ones designed for AI.
- Publishers are losing referral traffic because AI citations often don't lead to clicks, prompting Cloudflare to launch tools that let publishers block AI crawlers unless AI companies pay for access through its marketplace.
- AI responses with citations have risen more than fivefold in the past year, though just 6.8% of U.S. ChatGPT desktop queries included citations as of May 2026, with travel, retail, and sports queries generating cited responses more frequently.
- ChatGPT's U.S. desktop referrals improved after a May 7 search update, with the share of visits landing on webpages more than doubling from 25% in March 2026 to nearly 60% by May 30.
Why it matters: Google's shift from gateway to destination is accelerating — AI Overviews' near-tripling to 43% of searches and AI Mode's doubling to 279 million visits give Google more user time on its own platform while publishers lose the referral traffic that once funded the open web. Cloudflare's crawler-blocking marketplace is the first structural pushback against a system where Google indexes content but increasingly keeps users from clicking through.
