Reddit Tops AI Citation Charts. Brands Infiltrate Subreddits. The Moderators Noticed, Obviously.
Semrush data compiled for The Verge shows Reddit was the most-cited domain by ChatGPT, Perplexity, Gemini, and Google AI Mode in May. More than Wikipedia. More than scholarly repositories. Brands have noticed too and are attempting to manipulate subreddit conversations for visibility. Reddit claims 99% spam-free results through existing protections.
This demonstrates the Citation Economy mechanism. When AI models generate answers, they privilege domains they already trust. Reddit's structure, real humans debating real things, makes it catnip for language models seeking authentic signal. The lesson: where AI cites, marketers will follow. And then ruin it.
Reddit moderators are catching brands manipulating subreddits. Semrush, owned by Adobe, compiled the citation data. Reddit introduced native business tools only in 2024, rather late to its own party.
Step 1: Open ChatGPT and ask it a question about a product category you know well. Note whether Reddit appears in the answer or sources. Step 2: Visit the subreddit for that topic and read the top posts from the past week. Observe how brands might try to insert themselves. Step 3: Search Google for the same query with 'reddit' appended. Compare the quality of answers you find. You will understand why AI models favor this domain.
