Google is intensifying its advertising efforts within its AI-powered search features, including AI Mode and AI Overviews, to counter slower revenue growth from traditional search ads during the July-September 2026 quarter.
- AI Mode’s lower monetization slowed Google’s search revenue growth to 12%.
- Google will expand AI Mode ads internationally and launch dynamic multi-turn ads in the US.
- Advertisers face challenges as AI answers reduce traffic to external websites.
What happened
Google reported slower revenue growth from its Search advertising business in the third quarter of 2026, with total search ad revenue rising 12% to $63.3 billion. This was attributed to lower monetization in AI Mode, Google's conversational AI search interface. Alphabet executives acknowledged the impact of AI Mode queries on ad revenue growth during their earnings call, highlighting ongoing efforts to scale ads within AI-generated answers.
To address this, Google is broadening the presence of ads in AI Mode and AI Overviews, which provide AI-generated summaries atop traditional search results. The company is also launching multi-turn ads in the US that adapt as users interact with the AI, and is extending these advertising efforts to international markets for the first time. Additional revenue streams include AI-powered subscription products like Google One and new commerce features such as Universal Commerce Protocol and Universal Cart.
Why it matters
The shift to AI-driven search is altering user behavior by presenting direct answers that reduce clicks to external websites. This phenomenon has already impacted platforms dependent on Google traffic, such as Info Edge's education service Shiksha, which saw a 27% decline in billings due to AI directly addressing user queries. In Europe, publishers have raised concerns to regulators about the diminishing share of traffic referred from Google's AI search results.
As Google increases ads within its AI search features, publishers and advertisers may face even greater challenges in attracting website visits. This trend raises questions about the broader digital ecosystem's sustainability, balancing Google's ad revenue growth with the health of content creators and third-party sites that rely on search traffic.
What to watch next
Monitor how Google's expansion of ads within AI Mode and AI Overviews affects user engagement and publisher traffic, particularly as these features roll out globally beyond the initial US market. Industry observers will likely track changes to click-through rates on AI-generated answers and the effectiveness of multi-turn ads in maintaining ad performance amid evolving search behaviors.
Further developments in Google's AI commerce initiatives, including the adoption of Universal Commerce Protocol and Universal Cart, may create new revenue streams and alter advertiser strategies. Meanwhile, regulatory scrutiny may increase as stakeholders in Europe and other regions respond to the potential impact of AI search on content access and digital market fairness.
