Brand mentions
Also known as: Unlinked mentions, Co-citation
What is Unlinked mentions?
Brand mentions are references to a brand's name across the web — linked or not — and they are the strongest measured correlate of being named by AI assistants.
Ahrefs' 2025 analysis of 75,000 brands found branded web mentions correlated with AI Overview visibility at 0.664, versus 0.218 for backlinks. Its December 2025 follow-up found YouTube mentions correlated even more strongly, around 0.737, across ChatGPT, AI Mode and AI Overviews.
Correlation is not causation, but the direction is consistent: assistants learn who is associated with what from how often and where a brand is discussed.
