Google expands AI Search ads globally as core ad growth slows

Google is expanding ads in its AI-powered Search experiences globally, a clear signal that AI-generated results are becoming a mainstream monetization surface rather than an experiment. For builders, this means product discovery and acquisition strategies will need to account for sponsored placements inside AI responses, not just conventional search-result pages. Google has not disclosed new pricing or detailed rollout timing. The expansion comes as growth in Google's core advertising business slows, increasing pressure to turn AI Search usage into revenue. Alphabet reported third-quarter revenue of $127.6 billion, up 25% year over year. The broader takeaway is that AI search interfaces are moving closer to the economics of traditional search, with relevance, attribution, and ad placement likely to shape how users encounter products and services.
