- Similarweb reports Google AI Mode visits climbed from 126 million in June 2025 to 279 million by May 2026.
- Users are replacing short keyword queries with conversational prompts, increasing time spent directly on Google.
- Publishers face referral traffic challenges from AI citations, though desktop referral rates showed recent improvements.
In a recent analysis of the generative search landscape, market intelligence firm Similarweb noted that what began as a supplemental AI layer on top of search engines has transformed into an integral core of the search journey itself, as Google routes users into AI Overviews and conversational AI Mode.
During this same tracking period, visits to AI Mode experienced substantial growth, rising from 126 million sessions in June 2025 to 279 million by May 2026. The gathered data illustrates a profound evolution in how people navigate the web—moving away from the traditional model where Google served as a directory of blue links directing traffic outward, and shifting toward a paradigm where Google acts as the ultimate destination, synthesizing information from indexed websites directly.
This architectural shift appears to extend the duration users spend on Google's platform rather than utilizing it strictly as a discovery tool for external sites. Over the past year, Similarweb metrics indicate that the average length of Google search queries has grown, demonstrating that individuals are abandoning brief keyword entries in favor of extended, natural conversational phrasing tailored for AI interaction.

The structural transformation of search engines into closed-loop destinations presents complex monetization hurdles for digital publishers and news organizations. Traditional web economics rely heavily on outbound referral traffic and subsequent ad impressions. When AI-generated answers satisfy user intent directly on the search results page without requiring a click-through, content creators miss out on essential web traffic. This tension has prompted infrastructure providers like Cloudflare to roll out protective mechanisms enabling publishers to block unauthorized AI crawlers unless compensation agreements are met.
Nevertheless, a glimmer of optimism remains for content publishers. Regarding ChatGPT specifically, U.S. desktop referral traffic demonstrated a notable rebound following a search update deployed on May 7, 2026. The proportion of visits landing directly on external webpages more than doubled, climbing from 25% in March 2026 to nearly 60% by May 30, 2026, signaling that users continue to leverage prominent citation links when integrated effectively into AI search environments.
