Google appears to have blocked AI search results for the query "does trump show signs of dementia" as well as other questions about his mental acuity, even though it will show AI results for similar searches about other presidents. When making the search about President Trump, AI Overviews will display a message that says, "An AI Overview is not available for this search":
SEM Rush data for March-July shows ~13-18% of Google queries generated an AI summary. When people see one, they click fewer links (8% vs 15% CTR to web results), redistributing traffic. The majority of these 'lost clicks' are likely low value to brands - typically informational-led rather than purchasing-led. Reports show declining traffic without equivalent conversion drops. That may change as rollout continues.
Since the launch of Google AI Overviews in May 2024, zero-click search grew by 13 percentage points, reaching 69% in May 2025, while organic traffic to news sites declined significantly.
