Google's search and ad revenue grew 12% to $63.3 billion in Q3 2026, a deceleration from the previous quarter. This slowdown stems partly from a significant shift in queries to less-monetized AI Mode. Google is now pushing more ads into AI Overviews and AI Mode globally to close this revenue gap.
During Alphabet’s Q3 2026 earnings call, CBO Philipp Schindler admitted lower monetization in AI Mode negatively impacted search revenue. This is the clearest acknowledgment yet of AI search’s direct hit on Google’s core ad business.
Expect ads in AI Mode to scale rapidly into international markets, though Google has not specified which ones or when. The rollout of multi-turn ads in the US will provide an early indicator of user engagement with dynamic AI-driven ad formats.
🇮🇳 Why This Matters for India
Indian ad agencies and brand marketers in Bangalore and Delhi should track these new multi-turn AI ad formats for future campaign strategies as Google's global rollout expands here.
The Take
Google's claim of prioritizing "user experience and engagement first" sounds like PR when search revenue growth dips to 12%. The actual disruption lies in Gemini creating 1.5 billion ad assets, making ad campaigns cheaper and faster for advertisers, not just Google stuffing more ads into AI results.
