Google Put a Number on AI Clicks. You Can’t Check It.

For more than a year, the anxiety around AI search has come down to one question. When Google answers something at the top of the page, does anyone still click through to the sites underneath? Google’s head of Search has now given the most direct answer the company has offered yet, and it lands as a big, round, reassuring number that nobody outside Google can actually verify.

What Google said

Nick Fox, Google’s senior vice president of knowledge and information, laid it out in a post on LinkedIn, with a shorter version on X. He was answering the fear directly, that AI in Search would mean people stop clicking to websites. His response was that the opposite is happening. In his words, Google is now sending billions of clicks to websites every week through its AI features in Search alone, and he framed the whole thing as deliberate, since Google designed those features to connect people to sites.

He stacked that next to a figure Google has repeated for a while, that Search overall sends billions of clicks to the web every day. His argument, in short, is that people are using Google more than ever now that they can ask anything in their own words, and that AI search is adding traffic rather than taking it away.

The number without a denominator

The claim sounds decisive, and then you try to do anything with it. The daily figure for Search overall is one Google has said before. The weekly number tied specifically to AI features is new, and Google has never documented it anywhere. Both are rounded to billions, and that rounding is the problem.

A daily total for all of Search and a weekly total for AI features, both expressed in the same vague unit, can’t be lined up against each other. You can’t work out what share of clicks actually come from AI features, because there’s no denominator to divide by. Billions of clicks a week sounds enormous, but its real meaning depends entirely on the total it lives inside. If overall clicks are vastly larger, the AI slice could be modest. The number tells you AI features send some traffic. It doesn’t tell you how much, relative to everything else.

The gap gets more frustrating when you go looking for your own version of the figure. Search Console still doesn’t show it. The generative AI reports Google added earlier this year give you impressions, how often you appeared in an AI feature, but no click-level attribution for those features on your specific site. So the one company that can measure this precisely shared a platform-wide number you can’t break down, while the tool it gives you for your own data leaves that exact box empty.

What the outside studies show

Independent research keeps pointing the other way on the metric that reaches individual sites. A randomized field experiment run by researchers at the Indian School of Business and Carnegie Mellon University, covering more than a thousand people in the United States, found that AI Overviews cut organic clicks to outside websites by 38% on the queries where they showed up. What’s striking is the second half of that result. When the summaries were removed, people’s own reported satisfaction barely moved, which suggests the answer on the page was doing the job the click used to do.

The apparent contradiction resolves once you see both things can be true at once. Google’s billions-per-week is an absolute count across an enormous number of searches. The studies measure the click rate on individual result pages. Total clicks can stay gigantic while the odds that any single search sends a visit to any particular website keep falling. A rising tide of total volume and a shrinking per-page click rate are not in conflict, and most site owners are living in the second number, not the first.

What to actually do with this

The fair way to read Fox’s post is as a morale note, not a measurement. It’s Google defending a narrative, that the web is fine and AI search is traffic-positive, and it may well be right in aggregate. It simply can’t be checked, and it says nothing about your site in particular. Treating a denominator-free platform number as evidence about your own traffic is how teams end up reassured by data that was never about them.

So measure your own reality instead of anyone’s headline. Watch your actual visits in analytics, segment the queries where AI features appear against the ones where they don’t, and track where you’re cited rather than only where you rank. And keep doing the work that earns a click in a world with fewer of them to go around. When an AI answer only links to a handful of sources, being one of them is the entire game, and that comes from the same authority and citation-worthy content that link building and earned coverage have always built. Google can send billions of clicks a week and your site can still be losing them, and the only way to know which is true for you is to stop reading the aggregate and read your own numbers.
