Google’s AI search is growing faster than its advertising model can monetize
Alphabet says search queries are growing rapidly, but Search revenue and paid-click growth slowed in the third quarter as the company expands AI Overviews and AI Mode. Executives argue that many AI queries are incremental and could create future advertising opportunities; analysts question whether conversational searches will monetize as well as traditional ones. Google is spending heavily on AI infrastructure, while advertisers still report acceptable returns but cannot isolate performance from AI inventory.
Editorial summary · Publisher article
What matters
- Search revenue growth slowed to 12% year over year in the third quarter, while paid-click growth fell to 8%. (p1)
- Alphabet says AI Mode queries are often additional, research-oriented searches, but analysts warn that AI may also replace more valuable traditional queries. (p2, p3)
- Advertisers surveyed by Tinuiti increased Google paid-search spending while maintaining return targets, though they cannot separately measure AI-ad performance. (p2)
- An external working paper found lower retailer revenue per visit from ChatGPT ads, but its results do not establish how Google’s AI ads perform. (p3)
The unresolved business question
Google has begun expanding ads in AI Overviews and AI Mode and has discussed similar formats for Gemini. The central uncertainty is whether additional conversational queries will produce enough new revenue to offset any shift away from searches that currently monetize more reliably. Analysts expect advertising formats to evolve, but say the eventual model remains unproven. (p2, p3, p4)
Context & caveats
- Alphabet’s claims about incremental queries and promising ad experiments are company statements, not independently verified results.
- The cited ChatGPT advertising study measures retailer revenue rather than platform revenue and may reflect differences in user purchase intent.
Why this made the edition
The report combines Alphabet’s reported search and paid-click growth with executive statements, advertiser evidence, analyst views and an explicit caveat about an external working paper’s limits.
