- A post on X claiming Reddit makes up around 40% of AI citations sparked a wider debate among marketers and SEO professionals.
- The bigger story is not the exact number. It is how Reddit discussions are becoming part of how people validate products, brands and buying decisions.
For years, marketers have tried to understand what happens before a customer hits the buy button. They track rankings, watch website traffic, polish landing pages and study conversion funnels.
But one of the most decisive moments in the buying journey often happens somewhere brands do not control.
It happens when someone asks other people what they think.
That reality landed at the center of a conversation that picked up speed this week, after SEO and growth specialist Connor Gillivan argued that Reddit has quietly become one of the most important information sources in modern search. In a post on X, Gillivan claimed that Reddit now accounts for roughly 40% of citations across AI tools including ChatGPT, Claude and Perplexity, while also becoming more visible in traditional Google results.
Reddit is now the most cited source in AI search results.
And most brands are ignoring it completely.
Here’s how to optimize Reddit for SEO and AEO.

The 40% figure should be treated as a claim, not a confirmed benchmark. AI citation data can vary heavily depending on the tool, query set and methodology. But the reason the post spread is easy to understand: many marketers already see Reddit turning up more often in search journeys where users are looking for real opinions, product comparisons and firsthand experience.
Search for terms like “best CRM for startups,” “best project management software” or “best email marketing tool” and a familiar pattern starts to appear. Review platforms, software directories and company websites still show up, but Reddit discussions often sit right alongside them. The same pull is now visible in AI-powered discovery, where recommendation-style questions can draw from community conversations that feel more direct than polished marketing pages.
Reddit’s growing role in search is not only a ranking story. It is a trust story. Instead of taking a company’s word for itself, users want proof from people who have actually bought the product, tested the tool, dealt with the support team or compared it with alternatives.
Reddit is built for exactly that kind of messy research. Long threads fill up with recommendations, objections, follow-up questions and personal accounts that mirror how real buying decisions actually happen.
The Real Shift Is Happening in Trust, Not Rankings
The reactions to Gillivan’s post made clear why the topic hit a nerve. One reply from growth marketer Kevin Box captured the point directly:
“Reddit quietly became the place where buying decisions actually get validated. Everything else just supports it.”
That line names something many marketers already feel but struggle to measure. A potential customer may first discover a product through an ad, a Google result, a LinkedIn post or a colleague’s recommendation. But before they commit, they often want to hear from someone who already went through the process.
What worked? What broke? Was the pricing fair? Did the product do what the landing page promised? What would users choose if they had to decide again?
That need for reassurance is why Reddit threads carry so much weight. Traditional content often follows a script. Community conversations do not. One person recommends a tool, another pushes back and someone else adds a completely different experience. The result can be more useful than another optimized comparison page.
Another reply, from Leonardo Freixas, put the same shift in sharper terms:
That is the core of the story. Whether Reddit holds a specific position in Google for any given query is almost beside the point. Rankings shift. Platforms rise and fall. Algorithms change.
What matters more is that users are placing more trust in firsthand accounts than in carefully written brand content. Search engines and AI systems appear to be responding to that demand because those conversations often answer the questions people actually ask when they are close to making a decision.
A third comment, from Mariya Valeva, added another layer:
That discomfort matters. Visibility in search and AI-powered discovery is no longer only about who publishes the most, spends the most or has the cleanest content calendar. Useful conversations are competing for the same attention and in many cases they are winning because they sound closer to the way real people make decisions.
There is one uncomfortable contradiction in that trend. Reddit is increasingly treated as a source of authentic human experience at the same time that the platform is trying to separate real users from bots, spam and automated activity. In a recent post, Reddit CEO Steve Huffman said approved automated accounts will be labeled as apps, while suspicious or automated accounts may be asked to verify that a human is behind them. That makes Reddit valuable for AI search, but also vulnerable. If AI systems rely on Reddit because it looks human, manipulated Reddit threads become more than a moderation problem. They become a search quality problem.
Why This Matters for Brands
Part of what gives this conversation weight is that Reddit is no longer easy to dismiss as just another social platform. Reddit says it has more than 100,000 active communities and more than 450 million weekly active uniques, covering everything from software and finance to healthcare, education, travel and consumer products.
Those communities keep producing a stream of questions, recommendations and firsthand accounts written in the same language people use when they search. That matters because modern search has become more conversational. Whether someone is typing into Google or asking an AI tool directly, they usually want context, comparison and practical detail, not just a link.
There is also a bigger platform story behind this. Reuters reported in 2024 that Reddit entered a content licensing agreement with Google, allowing Google to use Reddit content to train AI models. The Verge also reported that the deal gave Google access to Reddit data and involved Google AI being used for Reddit search.
For marketers, this underlines a simple point: Reddit’s data is not just user chatter. It is valuable because it contains the kind of human discussion that search engines and AI systems want to understand.
For businesses, the risk goes beyond SEO. A company can rank well, publish consistently, run paid campaigns and still be absent from the conversations that shape how customers feel about it. Those conversations happen before someone books a demo, clicks a pricing page or fills out a lead form.
They happen when a buyer asks whether a tool is actually worth it. They happen when someone compares vendors. They happen when users discuss whether the support is good, whether the product is overhyped or whether a cheaper alternative does the job better.
The reaction to Gillivan’s post suggests many marketers are starting to feel that gap.
What Marketers Should Take From the Reddit Debate
The most important question is not whether Reddit really makes up 40% of AI citations. The number may be right, wrong or only true for a specific dataset.
The more important point is why so many marketers found it believable.
The comments and wider industry conversation keep pointing in the same direction: users are looking for proof that feels real, experience-based and community-tested. Search engines and AI systems are under pressure to surface exactly that kind of information because it often answers the practical questions people ask before making a decision.
That does not mean brands are powerless. It means the ground has spread. Trust is no longer formed only on company websites or through channels brands fully control.
Brands need to understand what users are saying in public community spaces, what objections appear again and again and which questions their own content still fails to answer. That does not mean spamming Reddit, planting fake recommendations or trying to turn every thread into a marketing channel. That approach will usually backfire.
The better lesson is editorial. If real users are asking better questions than your content answers, the content needs to improve. If community threads are more useful than your product pages, your product pages are missing something. If AI systems are pulling from public discussions, your reputation outside your own website matters more than ever.
This is also why the wider AI search and SEO debate is becoming harder to separate from brand trust. AI discovery is not just about being mentioned. It is about what kind of evidence exists around the brand when an answer is generated.
Platforms will shift. Algorithms will keep changing. But the impulse to hear from real people before spending money is not going away.
For marketers, the takeaway is simple: if users validate buying decisions on Reddit, brands cannot treat those conversations as a side channel anymore.
