Reddit mentions track AI visibility more closely than the press
Summary
Brand mentions inside Reddit threads that rank in Google track AI visibility more closely than press coverage or any other mention type in a new Ahrefs study.
Before buying placements, search your main non-branded queries, open the Reddit threads that rank and check whether your brand is named, since 29% of the brands studied had no such thread.
Brand mentions inside Reddit threads that rank in Google track AI visibility more closely than any other kind of mention, at a correlation of about 0.75, according to Ahrefs’ comparison of seven mention types published 3 November. Ahrefs matched 10,000 brands against how often each one surfaced in answers to 260 million non-branded prompts in ChatGPT, AI Mode and AI Overviews.
All seven mention types landed in a narrow band, so the order matters less than the spacing.
| Mention type | Correlation |
|---|---|
| Reddit mentions (in ranking threads) | 0.75 |
| Domain mentions | 0.70 |
| Webpage mentions | 0.70 |
| Total traffic of webpage mentions | 0.70 |
| News article mentions | 0.67 |
| YouTube mentions | 0.64 |
| TikTok mentions | 0.60 |
Nothing in that range is worth writing off. Reddit’s lead is partly built in, since Reddit licenses its content to both Google and OpenAI, and Ahrefs reports that in its Brand Radar prompt database Reddit is currently the second most cited source across the three AI surfaces, behind Wikipedia.
Two of the weaker results say more about where to spend than the winner does. Mentions weighted by the host page’s traffic scored 0.70, exactly the same as raw webpage mentions, and news article mentions came in at 0.67, slightly below mentions across the web at large. On this data a mention on a quiet niche page counts about as much as one on a large publication, and press coverage carries no premium. Ahrefs’ own advice is to chase a wide spread of mentions as well as big-name coverage. The likelier explanation of its numbers is that the spread is the part doing the work, which argues against spending a quarter’s budget on one placement.
Volume still pays, just not in proportion to what it costs. Ahrefs modelled how AI mentions grow as webpage mentions grow:
| Webpage mentions | Typical AI mentions |
|---|---|
| 1,000 | ~73 |
| 10,000 | ~273 |
Ten times the coverage returns roughly 3.7 times the AI mentions. The 9,000 extra pages in that jump buy about 200 more AI mentions, so a handful of new placements will not register, and a program that cannot sustain a large increase in the number of sites naming the brand is unlikely to show up in an AI answer either way.
Reddit mentions scale better on the same measure. A brand with ten times more Reddit mentions tends to get about 5.5 times more AI mentions, and most brands start from very little: the median brand had just 8 threads mentioning it, and 29% had none. For most brands, going from zero ranking threads to a few looks reachable in a way that a tenfold jump in total web coverage does not.
Two caveats change what to do with all of this. These are correlations, and Ahrefs says brand size explains part of the link between mentions and AI visibility without explaining all of it, so mention counts are a guide to where to spend rather than a lever with a known return. ChatGPT also tracked off-site mentions least closely of the three surfaces, on six of the seven factors, so a mention program judged on ChatGPT alone will look weaker than it does on Google’s two surfaces. The likelier explanation is that ChatGPT leans less on who is named where, which fits the earlier finding that being on the pages ChatGPT cites is not enough to get named.
What to do
- Search the non-branded queries you care about, open the Reddit threads that rank for them, and check whether your brand is named anywhere in the post or comments. The 0.75 figure covers mentions inside ranking threads, not Reddit mentions in general.
- Count your ranking threads before committing budget. Eight or more puts you ahead of half the brands Ahrefs studied. Zero puts you with the 29% with none.
- Stop paying a premium for reach on the strength of AI visibility alone. Traffic-weighted mentions scored no better than raw ones, so buy breadth across niche sites rather than one high-traffic placement.
- Measure across all three surfaces, in months rather than weeks, and expect noise inside any single week, given that half of tracked AI citations vanish by day two.
