Reddit mentions beat news for AI visibility, Ahrefs found at 260M prompts

A content team trying to get a brand into AI answers has a new ranking to argue over. Ahrefs published a study on 3 November 2026 that scored seven kinds of brand mention against AI visibility. It ran across 10,000 US brands and 260 million non-branded prompts in ChatGPT, AI Mode and AI Overviews.

The author is Louise Linehan, with data analysis from Xibeijia Guan. The underlying mention counts come from Ahrefs's own Brand Radar and Content Explorer products. The measurement is a Spearman rank correlation. The post states this at the top and repeats the caveat later.

The seven numbers

Ahrefs ranked the correlations like this. Reddit mentions led at 0.75. Domain mentions tied with webpage mentions at 0.70. Total traffic across webpage mentions matched them at 0.70. News articles came next at 0.67. YouTube was at 0.64. TikTok trailed at 0.60.

Two findings stand out from the ordering. News sits lower than plain web mentions. Many small-blog mentions correlate with AI visibility more strongly than a few named press hits. The traffic finding matches it: high-traffic page mentions scored the same as raw page counts.

Diminishing returns on volume

A brand with ten times more webpage mentions than its peer had about 3.7 times more AI mentions overall. The number splits by platform. AI Overviews ran at 3.5x. AI Mode ran at 3.0x. ChatGPT ran at 2.2x. The gap means more mentions help, but the return bends down.

The caveat the authors state

Ahrefs says "we can't say mentions cause AI visibility." Only the correlation is measured. The team controlled for search volume across bands of brand size. The webpage-to-AI link weakened but stayed significant. Reddit's 0.75 figure held up under the same control.

Why this matters for a GEO team

A brand team deciding where to spend time now has one ranking to lean on. The post suggests three practical moves. Earn a Reddit presence on the subreddits that discuss the brand's category. Grow raw web mentions through small blogs and partner sites, not only through press. Treat YouTube and TikTok mentions as the fourth and fifth lever, not the first.

The data lives inside Ahrefs's two products. The brand set and prompt set cannot be reproduced outside the company. That is the usual limit on this kind of GEO study. The study still gives one of the first public rankings of mention types against AI visibility at this scale.
