The Click Is Becoming the Exception, Not the Goal
The click is becoming the exception, not the goal.
On Friday last week, Google started automatically expanding full AI Overviews for some searches. Instead of a short AI summary followed by traditional results, users can now get the complete AI-generated answer, followed by an "Ask anything" box, before they ever reach the traditional links.
For publishers, the timing is particularly interesting because just ten days earlier, researchers published one of the strongest experiments I've seen on what AI search actually does to traffic. In a preregistered field experiment with 1,100 Google users, putting users into AI Mode reduced external click-through by 18.8 percentage points. The share of users clicking news sites fell by 12.5 points. When AI features were removed, click-through increased by 8.8 points.
There's another important finding: AI Mode didn't create more search sessions. It reduced them. In other words, the argument that AI might compensate publishers for lower CTR by generating substantially more search activity doesn't appear to hold up in this experiment.
I think publishers need to internalize what this means. We are still spending far too much time measuring "AI referral traffic" as if the click remains the primary unit of value. But Google is literally designing the experience so that the answer happens before the click. Referral traffic is increasingly becoming the residual outcome.
The new KPIs are inside the answer itself. Was your content cited? How prominently? Was your brand included? What position did it receive? Did the answer recommend your product, competitor or point of view?
That is the shift we are building Axioma around. Publishers need to measure not only the traffic AI sends them, but the value their content creates inside the answers AI gives to hundreds of millions of users.
The traffic economy measured clicks.
The recommendation economy needs to measure influence.
