Can Reddit fend off a new wave of AI SEO spam?
Reddit has become a prime target for covert marketing as AI chatbots increasingly cite it as a trusted source, prompting moderators on subreddits like r/SkincareAddiction to crack down on suspected brand-planted comments. In one case, a user repeatedly praised a skincare brand called Honeydew Labs across multiple unrelated threads, using language that read like promotional copy rather than genuine testimony, leading moderators to flag and filter the brand's mentions. The episode highlights a growing tension: as Reddit's authenticity becomes commercially valuable, it also becomes a target for the very SEO-style manipulation its users once fled Google search to avoid.
Data compiled for The Verge by Adobe-owned SEO firm Semrush found Reddit was the most-cited domain in May by AI tools including ChatGPT, Perplexity, and Google's Gemini and AI Mode, surpassing news publishers, academic repositories and even Wikipedia. Semrush also found Google is now inserting AI Overviews far more often into commercially-oriented searches, such as product comparisons, than it did a year earlier, giving brands strong incentive to seed favourable-sounding "organic" mentions on Reddit that AI systems might later surface to shoppers.
In short
- Reddit is now the most AI-cited website, ahead of Wikipedia and news sites
- Moderators are catching brands posting fake, AI-style promotional comments
- Marketers target Reddit because AI search tools quote it heavily to shoppers
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Advocates of a firm crackdown argue that Reddit's entire value proposition rests on the perception of unscripted, peer-to-peer honesty, and that this trust is now a scarce commodity being actively exploited now that AI tools treat the site as a truth-source for shoppers. On this view, moderators have not just a right but a duty to aggressively identify and filter suspicious repeat-brand-praise, since allowing covert marketing to fester would quietly convert Reddit into the very manipulated, SEO-gamed environment users originally fled Google search to escape, ultimately harming both ordinary users and the honest businesses that engage transparently.
The case against
Others would caution that policing "authenticity" is inherently subjective and fraught with risk, since genuine enthusiasts often do gush repeatedly about products they love, and volunteer moderators lack the tools or authority to reliably distinguish a paid plant from a passionate customer. From this perspective, an aggressive crackdown risks false accusations, silences legitimate small businesses and satisfied users trying to share honest recommendations, and hands enormous unaccountable power to unpaid moderators to decide whose speech counts as "real", all while the underlying problem, AI systems treating unverified forum comments as trustworthy sources, remains unaddressed at its true origin.
Explained simply
Reddit is made up of discussion forums called subreddits, where users share advice and experiences and volunteer moderators enforce each forum’s rules. Skincare forums, for example, can help people compare products through personal accounts and conversation.
AI chatbots increasingly draw on Reddit when answering questions, which makes discussions there more visible to people researching products. Search marketing, sometimes called SEO, is the practice of trying to make websites or brands appear more prominently in search results.
That visibility can create an incentive for companies to post praise that looks like an ordinary user’s opinion. If readers or AI tools cannot tell genuine recommendations from planted promotion, it may become harder to judge how trustworthy Reddit discussions are.
