Google's search revenue rose 12% YoY to $63.25B in Q3 2026, down from 14.5% in Q3 2025, with Google attributing the slowdown to "lower monetization" in AI Mode

Google search results now earn less money per query, reducing overall advertising revenue from the search engine.

Google's parent company Alphabet reported a Q3 revenue of $63.25 billion from search, marking a 12% year-over-year increase, a slight deceleration from the 14.5% growth seen in the prior year's third quarter. The company attributed this slowdown in revenue growth to "lower monetization" from its new AI Mode search feature. Despite significant infrastructure investments totaling $51.4 billion in Q3, Alphabet's net income decreased to $26.17 billion from $35 billion in Q3 of the previous year. Alphabet CEO Sundar Pichai expressed optimism about future AI revenue, highlighting the rapid adoption of the Gemini app and the potential of agentic AI tools, which will initially focus on business customers due to high security and governance demands. The company plans to introduce AI Mode features to Search and the Gemini app, though it did not specify a timeline or address potential monetization challenges.

The slowdown in Google's search revenue growth, directly linked to lower monetization from AI Mode, signals a critical challenge in translating AI adoption into profitable revenue streams. While the company attributes this to "lower monetization" and "upper funnel" queries, it underscores the immediate difficulty of monetizing new AI-driven search experiences at a scale comparable to traditional ad models. This revenue gap is particularly concerning given Google's substantial infrastructure investments, raising questions about the long-term financial viability of its AI search strategy if monetization improvements are not realized quickly.

The strategic pivot to AI-powered search, while increasing query volume, is currently undermining a core revenue driver for Alphabet. The company's acknowledgement of lower monetization in AI Mode, coupled with the ongoing massive capital expenditures on infrastructure, points to a potential financial strain. The upcoming focus on agentic AI tools for businesses suggests a targeted approach to higher-value monetization, but the broader impact on the core search product and its profitability remains uncertain as Google grapples with balancing innovation and immediate revenue generation.
