Publishers and businesses say Google's AI Mode is already reducing human visits by answering queries with Gemini inside Search instead of sending users to outside websites.
That shift keeps people on Google longer and fuels fears of a "Google Zero" future in which search delivers little meaningful referral traffic to the open web.
Google disputes the damage, saying its AI features still send billions of clicks to websites and adding previews, preferred sources and publisher tools to preserve links to the wider internet.
Wikipedia and other publishers still report pressure from falling traffic and heavier AI data collection, while the U.K. Competition and Markets Authority has pushed for more transparency, attribution and publisher control.
The clash follows Google's broader AI overhaul of Search, unveiled earlier on Monday, which recast the search box around conversational answers after 25 years of link-first design.
As Google's AI provides direct answers, is the era of visiting websites and the open web we knew officially over?

Google's AI Search Overhaul 2026: 40% Drop in Publisher Traffic, Regulatory Backlash, and the Future of the Open Web
Overview
Between May and July 2026, Google launched a major AI-powered overhaul of its Search platform, marking a historic shift in how people find information online. Announced at the I/O conference, this transformation moved Google Search beyond the familiar 'ten blue links' by integrating Gemini 3.5 Flash as the default AI model for users worldwide. The new system delivers faster, more affordable, and advanced performance, fundamentally changing the search experience. As a result, users now interact with dynamic, AI-generated content instead of simple lists of links, signaling the biggest change to Google Search in over 25 years.
