Google Expands AI Search Ads Worldwide

Google is taking ads in its AI-powered search results into international markets, a sensible bit of monetization timing just as the old machine shows a little less torque.

The announcement came during Alphabet’s third-quarter earnings call, where the company reported $127.6 billion in revenue, up 25% from a year earlier. The more useful figure for this story was narrower: Google Search revenue rose 12%, down from 17% growth in the second quarter and 19% in the first. Alphabet shares fell 8% after the results.

That sequence does not prove investors sold the stock because of AI search ads, or because search growth cooled, or because expectations had wandered into the usual dangerous neighborhood. It does show why Google suddenly sounds less philosophical about AI in search and more interested in charging rent.

Philipp Schindler, Alphabet’s chief business officer, said Google is scaling ads inside AI Overviews and AI Mode to more users and more queries, including a global expansion of that “monetization footprint” for the first time. The company is also adding multi-turn ads in AI Mode in the U.S., meaning ad formats can keep pace with longer, conversational searches rather than just sit beside a list of blue links like a relic from a calmer internet.

Google’s argument is that user behavior is changing in ways that can support those formats. Sundar Pichai said search queries are growing at their fastest year-over-year rate in five years, though he did not give the rate. He also said AI Mode queries are three times longer on average than traditional searches, and that one in five AI Mode searches globally involves voice, images or documents.

The company’s evidence that the ads work is still selective. Schindler said click-through rates for sponsored product listings in AI Mode are comparable with organic listings, and that Google’s research shows users find the ads relevant. Comparable to organic is encouraging, but it is not the same as proving durable revenue at scale, especially once more advertisers, more queries and more markets are pushed through the system.

Google Services, which includes Search, generated $96.3 billion in revenue, up 11%. That remains an enormous business. It is just no longer growing at a rate that lets Google treat AI monetization as an interesting side project.
