A new analysis by Ahrefs' Brand Radar has shed light on which domains are most frequently cited by Google's AI Mode.

Based on a database of 5.5 million AI Mode queries, the findings reveal a telling hierarchy of trusted sources.

The 100 most cited domains include Wikipedia, YouTube, Google's official blog, Reddit, and Google itself at the very top.

Interestingly, the report also highlights a preference for user-generated content (UGC). Platforms like YouTube, Reddit, Quora, Instagram, Yelp, TripAdvisor, LinkedIn, and TikTok feature prominently on the list - suggesting that AI Mode taps into the collective voice of users as much as authoritative sources.
