Google unveils its biggest search overhaul in 25 years with AI agents and Gemini 3.5 Flash
Publishers and news outlets fear that AI summaries will significantly reduce website traffic as Google's new search era begins
Google has announced the most significant transformation of its search product in 25 years, converting what has historically been a simple query-and-answer tool into an intelligent, AI-powered assistant capable of handling complex, multi-step tasks.
What is changing
The overhaul, unveiled at Google I/O 2026, integrates Gemini 3.5 Flash into the search experience, launches proactive "search agents," and introduces a reimagined search interface.
The new "intelligent search box" is designed to handle queries in a conversational format and accept multiple input types including images, text, videos, files, and Chrome tabs.
AI agents to monitor the web around the clock
A centrepiece of the update is the introduction of information agents — AI-powered tools that will monitor web data continuously for purposes including shopping, finance, and news, delivering synthesised updates tailored to individual user inputs.
Google's head of Search, Liz Reid, explained the capability at a press briefing: "You could send an alert to track market movements in a particular sector with very specific parameters, and the agent will map out a monitoring plan for you, including the tools and the data it needs to access." The agents are set to launch this summer for Pro and Ultra subscribers.
Personal intelligence and global reach
The update also expands personal intelligence features, now available in 98 languages across nearly 200 countries, free of charge.
Users can connect personal data from Gmail, Google Calendar, and Google Photos to give the AI greater context, while retaining full control over privacy and data usage.
Using Google Antigravity and Gemini 3.5 Flash, Search will be capable of generating custom responses that include interactive visuals, graphs, and simulations.
Publisher fears over web traffic
The announcement has raised serious concerns among publishers and media organisations. AI-generated summaries within search results are already eating into referral traffic, and the new update is expected to accelerate that trend.
A report by the Reuters Institute for the Study of Journalism warned that media executives globally fear search engine referrals could decline by 43 per cent over three years.
News sites, the report added, are at risk of losing a third of their search traffic within a year as AI-powered assistance becomes the norm.
Senior research associate Nic Newman said: "It is not clear what comes next. Publishers fear that AI chatbots are creating a new convenient way of accessing information that could leave news brands – and journalists – out in the cold."
The reaction online has been equally alarmed. "That whooshing sound you hear is the revenue of every non-paywalled journalism outlet disappearing," one user posted.
Another wrote: "Genuinely every website you love is about to get CRUSHED by this after barely surviving literal years of declining search traffic." A third suggested: "RIP website traffic. Might I suggest investing in newsletters."
