Alphabet reported a quarter on Wednesday that reads like a record at first glance: $127.6 billion in revenue, up 25 percent year over year. The stock still fell about 8 percent. The reason fits in one line: Search advertising grew 12 percent — down from 17 percent in the second quarter and 19 percent in the first. The curve is bending down, and in the same breath Google announced it is rolling ads in its AI search surfaces out worldwide for the first time.
"We are now scaling high-quality ads within AI overviews in AI mode to more users and queries," chief business officer Philipp Schindler said on the earnings call. "This includes taking our monetization footprint global for the first time." Concretely: ads in AI Mode into international markets, plus multi-turn ads and AI Mode in the US.
The paradox
Google is simultaneously reporting more searches and slower-growing search ad revenue. CEO Sundar Pichai said queries grew at their fastest year-over-year rate in five years, without giving the number. In AI Mode, queries average three times the length of traditional searches, one in five AI Mode searches involves voice, images or documents, and Google counts more than 50 billion visual searches a month.
More queries, longer queries — and a flattening revenue curve anyway. That is the real story of the quarter. Generative surfaces answer questions instead of pointing at ten blue links, and those links were where advertising earned its money for two decades. Google has to move the ad to where the answer is.
The numbers that matter
According to Schindler, click-through rates for sponsored product listings in AI Mode are already comparable to organic listings — a signal investors wanted to hear, because it addresses the fear of an unmonetizable surface. Google also cites user research showing people find the ads relevant. It published no independent evidence for either.
The rest of the quarter told a different story: Google Services, which includes Search, generated $96.3 billion, up 11 percent. Google Cloud grew 103 percent to $30.7 billion. The infrastructure for AI is currently selling far better than the advertising that pays for it.
What happens now
The international expansion is a bet with an open ending. Ads inside generative answers carry a familiar risk: someone who gets an answer clicks less often, and someone who clicks less sees fewer ads — unless the ad is inside the answer itself. That is precisely what Google is building: conversational discovery ads that respond to the user's question, and sponsored recommendations embedded in generated answers. The company has been working on those Gemini-powered formats since May.
For publishers and advertisers, the line between editorial and advertising moves further into a surface users read as an answer rather than as inventory. For Google, the question shifts from "how much advertising can a search page carry?" to "how much advertising can an answer that presents itself as an answer carry?"
The next few earnings reports will show whether the global rollout bends the curve back. The current claim that the formats work rests on one sentence: click-through is comparable. That is a start, not a proof.
