You ask ChatGPT for "the best CRM for freelancers" or "an alternative to [tool]" and the answer comes back with two or three names. Where does it get them? Increasingly, from Reddit and forums. In a Semrush study of 150,000 AI citations (June 2025), 40.1% of references pointed to Reddit —far ahead of Wikipedia (26.3%) and YouTube (23.5%)—. And it’s no accident: Google and OpenAI pay Reddit tens of millions a year to read its conversations. The uncomfortable consequence for anyone who only optimized their website: if your category gets discussed in communities and your brand isn’t there, the AI builds the answer without you. This is how to get into that conversation.
Why AI cites Reddit more than any website
A model answering "which is best?" needs something your product page can’t give it: the opinion of people who’ve actually used it. That lives in forums. So when you measure the sources AI cites, communities beat corporate sites hands down. In Semrush’s June 2025 analysis of 150,000 citations across 5,000 keywords, Reddit took 40.1% of references; Wikipedia, 26.3%; YouTube, 23.5%. And not every assistant behaves the same: Perplexity has leaned on Reddit in close to 47% of its answers, while ChatGPT spreads more between Wikipedia and communities. The picture shifts by platform, but the direction is the same: AI reads the conversation, not just the advertising.
On top of the content reason sits a business one. In February 2024, Google signed a licensing deal with Reddit worth around $60 million a year; in May 2024, OpenAI closed a similar one to access its conversations. When the platform itself has a contract for the AI to read its data, that content isn’t just another source: it’s a source with a fast lane. Optimizing your website still matters, but it’s only half the board. Forums are one of the three off-page families the model reads; the others —press, directories and reviews— and why all of them weigh more than your own site are covered in mentions, reviews and press to appear in AI.
| Surface | What it gives the AI | How much control you have |
|---|---|---|
| Your website | Official spec: what you do, prices, features | Total |
| Reddit / forums | Real user opinion: pros, cons, comparisons | None directly — earned |
| Wikipedia / media | Entity verification and notability | Indirect |
You can’t optimize a forum the way you optimize your site
Can you "rank" a brand on Reddit with your website’s tricks? No.
You’re not in charge there: a community decides whether you add value or clutter.
This is where most playbooks go wrong. Your website gets optimized: you change the H1, tune the schema, speed it up. A forum doesn’t. Reddit is third-party territory with its own rules, human moderators, and a long-standing allergy to marketing. There’s no button to "rank" your brand; there’s only a community deciding whether your contribution earns its place or gets downvoted. That’s the mindset shift: you go from controlling the surface to earning a spot on it.
What you can do, in order of payoff:
- Find where your category is discussed. Before you participate, listen: which subreddits, forums, or Quora threads surface when you search your category and your competitors. That’s where the AI is reading; the rest is noise.
- Be genuinely useful, with an identity. Answer technical questions, add data, compare honestly —even when your product isn’t the best fit for that case—. Usefulness is what survives moderation and what the AI pulls as credible opinion.
- Trigger the organic mention. The goal isn’t for you to talk about your brand: it’s for a happy user to name it. That’s earned with product and support, not copy. A third party’s "I used X and it solved this" beats ten posts of your own.
- Watch and add context. When a thread comparing your category shows up, add the missing data —without selling—. AI cites threads with concrete information, not commercial monologues.
How to earn presence in the communities AI reads
Community presence is slow work, not a campaign. The brand the AI ends up naming is the one that’s been useful for months where its category is discussed, not the one that showed up for a week handing out links. Three fronts that work:
- Real, sustained accounts, with a history of honest participation —not fresh profiles that only talk about one product. Age and karma aren’t vanity: they’re the signal that separates a community member from an ad with legs.
- Content people want to cite: an honest comparison, a data point of your own, a long clear answer to a recurring question. It’s what others link within the forum itself and what the AI pulls to justify a recommendation.
- Support where the customer is: many brands find their best GEO is actually helping people in their sector’s subreddit. Solving a problem in public, in full view, generates exactly the kind of positive mention that feeds the AI’s answer.
- Alliances with real voices: power users, integrators, niche creators. Let them talk about you because you add value, not because you paid for a covert review —that’s a different thing, and it costs you—.
Astroturfing has a price: why the shortcut costs you
By now the temptation is obvious: if the AI cites Reddit, let’s manufacture threads that speak well of us. It’s the worst idea in the book, for three reasons. First, detection: Reddit and its moderators have spent years hunting covert marketing —coordinated new accounts, repeated links, suspiciously polished praise— and ban without warning, sometimes the whole domain. Second, brand risk: a thread exposing your fake campaign is persistent negative content, and the AI pulls the bad too; you risk the answer naming you doing it to warn people off. Third, the fragility of the channel: when Reddit sued Perplexity over scraping in October 2025, Reddit citations in Perplexity dropped 86%; building your visibility on tricks inside someone else’s platform is building on sand. The presence that lasts is the one earned by being useful. There’s no shortcut that doesn’t eventually come due.
Measure it: do they name you in the threads AI pulls from?
You find out by measuring in two layers, not by guessing.
Working communities without measuring is faith, not strategy. Measurement has two layers. The first, in the community itself: identify the 10-15 threads that surface when you search your category and your competitors, and track whether your brand appears in them, in what tone, and how often. The second, in the AI’s answer: once a month, run your category’s real buying queries —"best [product] for [case]", "alternative to [competitor]", "what do people recommend for [problem]?"— in ChatGPT, Perplexity, and Google AI, and note whether they name you, with what argument, and whether the cited source is a forum. Crossing the two layers tells you whether your presence in the conversation is turning into AI mentions.
And check the boring stuff: that the threads you appear in are still live and not deleted; that your participation hasn’t crossed the line that trips moderation; that you’re in the communities where your category is actually discussed and not just where you’d like it to be. On timing, honesty: a relevant conversation can feed answers within weeks thanks to the access deals, but being the brand the AI names consistently takes months of real presence.
