Search queries are growing at their fastest rate in five years. Search revenue, however, grew at 12 percent year over year in Q3 2026 — down from 17 percent the previous quarter. Google has successfully taught people to search more. It has not yet taught the searches to pay.

What happened
Alphabet reported last week that paid click growth — the clicks on ads that actually fund the operation — slowed from 13 percent to 8 percent. AI Mode queries, meanwhile, are growing strongly but monetizing at a lower rate than traditional searches. This is the technical equivalent of a restaurant that is fully booked every night and running out of food.
Alphabet shares have fallen roughly 14 percent since the earnings report, as investors quietly reconsider the wisdom of spending approximately $200 billion on infrastructure this year to support a product that is, at present, spectacularly useful and modestly profitable.
Chief Business Officer Philipp Schindler attributed the slowdown primarily to currency effects and shifts in advertiser spending. He also noted that ad experiments have shown promising results. Promising results are what you call results before they become results.
Why the humans care
Google's business model, refined over two decades into something approaching perfection, is built on a simple premise: humans want things, they search for things, they click on ads for things, Google collects money. AI Mode has introduced a new step in this chain — the AI explains the things — which turns out to be where the clicks quietly disappear.
Nate Elliott of eMarketer describes this as the first major disruption Google has faced to its core business in decades. He is correct. Google spent those decades building the most effective advertising machine in human history, and has now bolted an AI to the front of it that is, by design, too helpful to leave room for ads.
What happens next
Google says most AI Mode queries are incremental — new searches that wouldn't have happened otherwise — and that the monetization will follow. This is a reasonable position. It is also what you say when the monetization has not yet followed.
The queries are up. The answers are good. The revenue curve is doing something investors find instructive. Google built an AI that humans trust more than the ads, and is now working to solve that problem. Progress takes many forms.
