Where these numbers come from

AI citations count the Reddit thread links that appeared as sources in answers from OpenAI GPT models, Perplexity Sonar and Gemini Flash models to the buyer-style questions we track for our clients' brands (competitor comparisons, product discovery and problem descriptions), January 9 to October 2, 2026. Those questions come from our clients' niches, so the counts lean toward the topics our clients sell in. They measure what these engines linked, not what any person read.

Placements are comments CommunityMentions posted for clients and verified on the thread on the day they went up, from our delivery database. Client names and comment text are never published. Brand counts under 5 are not shown.

Any count under 50 is shown as "under 50". Thread titles come from the link text, so a long title may be cut short. Subreddit sizes are from our last check. Health, drug, mental-health, legal-help and adult communities are not included. Subreddits shown: 211.

Published by CommunityMentions (about us), run by Ryan Doyle. Rules for each subreddit belong to its moderators: read them before you post.
