Google AI search keeps users inside, cutting web traffic by up to 40%

Google’s AI‑powered “AI Mode” now retains users for about 75% of sessions, meaning most people never leave Google to browse the open web—a shift that has cut human traffic to publisher sites by roughly 40% in recent months [1].

AI Mode reshapes user behavior

Since launching AI Mode in 2023, Google has seen users craft queries that are three times longer than the keyword‑heavy searches of the past, and they now spend between one and nine extra minutes per session in the AI interface [1]. Three independent studies cited by The New York Times show that in roughly three‑quarters of AI Mode sessions, users never click through to an external website, effectively turning the search experience into a closed‑loop conversation.

Impact on the open web and publishers

The shift has tangible economic consequences. Cloudflare reports that human traffic to websites in sectors such as finance, publishing, and retail fell nearly 40% between June 2025 and April 2026, while non‑human (bot) traffic now exceeds 50% of overall web visits [1]. Wikipedia noted an 8% dip in human visitors over the past year, attributing part of the decline to Google’s AI‑driven answers that bypass the encyclopedia’s pages [1]. Google counters the narrative, claiming its AI features still send “billions of clicks” to the web each week and that its methodology for measuring traffic drops is flawed [1].

Regulatory and industry response

Britain’s Competition and Markets Authority recently ordered Google to modify its AI search tools in the UK, mandating clear attribution links and an opt‑out mechanism for site owners who do not want their content summarized by AI [1]. Meanwhile, publishers like Vox Media have begun divesting assets, citing the “decimation of search traffic” as a factor in recent sales [1].

What to watch

• UK CMA compliance deadline – monitor when Google implements the required attribution and opt‑out features across its global search platform.
• Google’s next AI feature rollout – any new tools that push users back to external sites (e.g., preview links or “preferred sources”) could alter the current traffic dynamics.
• Publisher revenue reports – earnings from media companies in the next quarter will reveal whether the traffic decline continues or stabilises.

The emergence of AI Mode signals a fundamental re‑orientation of Google’s role from an open‑web gateway to a self‑contained information hub, raising questions about the long‑term viability of the web’s traditional traffic‑driven economics.
