At its I/O conference in May, Google rebuilt its search box for the first time in more than 25 years and wrapped it in AI. Its own numbers: over a billion people use AI Mode every month, AI-powered searches are more than doubling every quarter, and overall search traffic just hit an all-time high. Now the other number: when Google’s AI answers a question and cites sources, people click through to one of those sources about 1% of the time. Both are true at once. That gap is the real story here, more than any single feature Google shipped this year.
Google’s New Homepage The new search box takes photos, files, videos, or open Chrome tabs as input, not just typed words, and runs on a new model, Gemini 3.5 Flash. Google backed it with the numbers above.
Two weeks later, it gave website owners two tools: “Preferred Sources”, so favorite sites appear more in AI answers, and, on June 2nd, an opt-out toggle in Search Console to keep a site out of AI Overviews and AI Mode entirely. Publishers got a choice. Users didn’t, as the next section shows.
A Washington University in St. Louis study tracked 55,393 real queries over 40 days. AI Overviews appeared for 14% of all searches, but nearly 65% of question-style searches, versus under 10% of others. Almost 30% of the sites cited weren’t in the normal search results shown alongside them. Of nearly 100,000 individual claims checked, 11% weren’t actually backed up by the source cited.
A Pew Research study of 900 U.S. adults’ real browsing data found people click through to an AI Overview’s cited source in only about 1% of visits, and that AI Overviews were more likely to end the browsing session altogether.

Some early coverage described the classic Search button as being replaced. It wasn’t. Robby Stein, Google’s VP of Product for Search, confirmed the test directly, on the record:
The merging of Gemini and Search continues. It’s a big deal when Google adds features to the homepage… https://t.co/j8xeCBlGnh

So the buttons are additions, not a replacement, and Google has now put a name and a description to the test: small, desktop-only, aimed at surfacing AI Mode features people might not otherwise find. What Google hasn’t said is how many people are seeing it, or whether it expands beyond this test.
Microsoft just went the other way with its own AI-in-search decision, adding a “kill switch” to disable Bing’s Copilot answers. Its search lead: “not everyone wants to use AI for everything all the time.” Google’s test nudges people toward AI Mode without touching the box itself, a smaller move than some early reports suggested, but one pointed in the same direction.
A billion monthly users is real. But the numbers Google published don’t answer whether people are getting what they came for. The numbers that do, a 1% click-through rate and an 11% error rate on cited claims, point somewhere less flattering. Whether the homepage test expands beyond a small desktop trial, and whether Google responds to what the research found, is now on Google to answer.
