Google AI Overviews Now Appear on 21% of Searches, New Data Reveals

A new study by Ahrefs has found that Google’s AI Overviews now appear on about 21% of all searches.

The analysis looked at more than 146 million search results to understand when and where these AI-generated summaries show up.

The findings show that Google AI Overviews appear more often in long, question-style searches and less often in local or breaking news queries.

AI Overviews Dominate Informational Searches

Ahrefs found that AI Overviews (AIOs) mostly appear in informational and question-based searches — the kind users make to learn or explore topics.

Key Highlights:

• Appear on 20.5% of all keywords analyzed.
  
• Question-style queries trigger AIOs 57.9% of the time.
  
• Longer searches (7+ words) show AIOs in 46.4% of results.
  
• Single-word searches show AIOs just 9.5% of the time.
  
• Informational intent drives nearly 99.9% of AIO results.
  

This means Google mainly uses AI Overviews when users ask detailed or educational questions rather than quick lookups or navigational queries.

Lower Presence in News, Local, and Commercial Queries

AI Overviews rarely appear for news, local, and shopping-related searches. Google seems to limit AIOs where freshness and accuracy are most important.

Findings by Category:

• News-related searches: Only 6.3% show AIOs.
  
• Local searches: Just 7.9% trigger AI Overviews.
  
• Shopping queries: Only 3.2% show AIOs.
  
• Health-related (YMYL) searches: Appear in 44.1% of cases.
  

Experts believe this selective rollout helps Google maintain trust and accuracy in sensitive or real-time topics.
