Google expands AI Search ads globally as core ad growth slows

Sponsored listings in AI Overviews now match organic click-through rates globally.

Google is expanding advertisements within its AI-powered Search experiences to international markets, aiming to bolster revenue as its core search ad business experiences slowing growth. During Alphabet's third-quarter earnings call, the company reported $127.6 billion in revenue, a 25% year-over-year increase. However, Search advertising growth decelerated to 12% year-over-year in Q3, down from 17% in Q2 and 19% in Q1, prompting an 8% drop in Alphabet shares. Google's chief business officer, Philipp Schindler, stated that high-quality ads are being scaled within AI overviews globally, including multi-turn ads and AI mode in the U.S. Early results indicate that sponsored product listings in AI Mode have click-through rates comparable to organic listings, and user research suggests ads are perceived as relevant. This expansion follows Google's May announcement of new Gemini-powered ad formats.

This global rollout of AI-driven ads signifies Google's aggressive strategy to monetize generative AI capabilities, especially as traditional search ad revenue growth falters. The company is betting that the enhanced user engagement and longer, more complex queries generated by AI features will create new avenues for advertising. The reported comparability of click-through rates between AI-powered sponsored listings and organic results suggests a potentially significant new revenue stream that could offset the deceleration in core search advertising. This move directly impacts the advertising market by potentially increasing ad load and introducing new formats that users must navigate, while also signaling a shift in how businesses will need to optimize for visibility in search results.

The expansion puts pressure on competitors and advertisers to adapt to this evolving search landscape, as AI becomes an increasingly integrated part of the user experience and a critical component of ad delivery. As Google rolls out these monetization features globally, advertisers will need to invest in understanding and optimizing for AI-driven queries and ad placements. The success of these AI-powered ads could also influence the development of similar monetization strategies by other tech giants exploring generative AI for their platforms, potentially reshaping the digital advertising ecosystem.
