Lately, a lot of people in the AEO sphere keep offering the same advice: get on Reddit. There’s truth to the advice, but simply spamming threads with your business won’t do what you want it to. In fact, it might cause the opposite effect.
Reddit, YouTube, and LinkedIn appear regularly in AI answer citations, which means that useful contributions on those sites really can put your business in front of audiences using answer engines. But that visibility is borrowed. You’re essentially renting from a domain the engine already recognizes and trusts instead of building authority on a digital platform you fully control.
Reddit itself makes this risk especially clear. Over the last couple of years, the platform has moved towards gating AI access to its content through crawler restrictions and licensing arrangements. Google’s reported Reddit deal was valued at roughly $60 million annually, while Reddit has also sued Perplexity over alleged unauthorized data access.
The clearest example is what just happened at ChatGPT. In August 2026, Reddit's share of ChatGPT citations dropped from about 3.8% to roughly 0.5% in a matter of days — an 86% collapse — according to data from the AI-visibility tracker PromptWatch. The striking part isn't the number; it's that no one can fully explain it. OpenAI hasn't said why, PromptWatch notes its data shows when the shift happened but not why, and analysts are still debating the cause — a backend change to how ChatGPT searches, an unrelated shift upstream, or Reddit's own move to block crawlers. Any of those are possible. And that's exactly the point: Reddit's visibility in the most-used AI assistant was wiped out in a week, for reasons its own community can't see or control. That's what renting looks like.
Sometimes, but what you gain is rented presence and not owned authority. Reddit can help you get cited because Reddit itself is a commonly cited domain, but that doesn’t mean AI decided your company has authority. It just means you’re benefiting from the visibility of a platform that already has significant visibility of its own. It helps to think of what’s happening when an AI engine cites a Reddit thread.
Someone asks a question, and the engine goes looking for information that can help answer it. It finds a Reddit thread where people have discussed that exact question. The engine decides the discussion is useful and cites it.
Maybe someone mentioned your company, your product, or something you published in the comments on the thread. Your brand got in front of the person asking the question, but you need to understand something: the AI cited Reddit. It didn’t necessarily cite you.
Our AI Citation Study found that most third-party citations fall into a handful of familiar domains, specifically Reddit, YouTube, LinkedIn, and to a lesser extent, Medium. Each is cited hundreds of times, so a brand that’s established on the platforms and contributes genuinely useful material can become part of the AI citation ecosystem. This is actually great news for smaller marketing teams because it saves time, effort, and overhead. There are places where AI is already searching, and you can utilize those places rather than trying to create your own “AI authority” signal.
But there’s a difference between being present somewhere AI looks and owning the thing AI knows you for. Publishing on Reddit can give you access to Reddit’s existing visibility, but publishing on your own website gives you an asset you can update regularly, obtain metrics from, and connect to your services.
Perplexity leaned on Reddit, YouTube, LinkedIn, and other third-party community sources roughly four times more than the other engines in our citation study. (It’s important to remember that Perplexity is far less commonly used than ChatGPT or Gemini.) ChatGPT relied on those sources the least. Gemini and Claude hovered between the two extremes, with Gemini having an affinity for YouTube and other Google products. That means the value of a Reddit strategy depends partly on which AI engines actually matter to your audience. This is one reason why blanket AEO advice is somewhat misleading.
AI visibility isn’t one uniform behavior across every answer engine, and engine usage is also variable. Different platforms have different audiences, use cases, retrieval systems, partnerships, and source preferences. Before building a platform-specific program, teams should be clear about which engines matter most to their buyers and where those buyers actually conduct research.
Perplexity was the AI engine that cited Reddit the most in our study, but ironically, Reddit is now taking a much harder line on third-party AI access. Reddit’s lawsuit against Perplexity and several other scraping firms states that they accessed Reddit’s content outside of authorized licensing channels and violated U.S. copyright law. Meanwhile, Google has a formal arrangement with Reddit that gives Google access to Reddit’s Data API and content for specified uses, including for training Google AI Overview and Gemini on Reddit posts, which creates a very opaque “back door” for Reddit influence on AI answers that can’t be tracked with citations.
When you appear on Reddit, YouTube, or LinkedIn, you may gain exposure on a domain AI frequently cites, build credibility with people who encounter an insightful, helpful contribution, cultivate traffic, discovery, or brand familiarity, and/or gain a chance to lead readers toward a stronger owned resource. What you don’t gain is control over the domain, its policies, its distribution rules, its search visibility, or its business relationships.
When the platform changes the rules, the platform decides what happens next. Access can be gated, licensed, blocked, or litigated without your input. Ultimately, whatever they do is out of your control.
Reddit began implementing crawler policy changes to its Robots Exclusion Protocol in 2024, and the changes are now fully implemented. The changes are designed to limit or block AI crawler bots without approved agreements, while continuing to rate-limit and restrict unknown crawlers. The protocol is intended to deter AI companies from using Reddit content without an agreement, such as the deal struck with Google.
This fundamentally changes the practical value of “renting space” using a borrowed platform. If an AI can’t access a platform’s content or can only access it under an agreement, then being active on that platform may have a different effect than it did a few months prior. The content may still reach people on the platform or in a traditional search, but its availability to an answer engine isn’t guaranteed.
“So I've long been a proponent of not building your empire on rented land, and I still think that's true. I think part of what you're seeing right now is the exact result of that. When you hear anything about these robots. txt files being added on Reddit, it's because people were gaming a system, right? And when you game a system you don't own, you're gonna lose.” -Tracy Graziani
Just like rented physical space, a lot can be done with rented digital space.. You can build a thriving business, reach thousands of people, and garner a huge following. But because you don’t own the space, you’re limited by what you’re allowed to do, and anything the landlord decides to do is completely out of your control.
This isn’t a criticism of Reddit or any other third-party platform. Platforms have every right to decide how their content is accessed and monetized. It is, however, a reminder for marketers. Once we find a platform that works, we have a tendency to start treating it like permanent infrastructure. Then, that platform changes and everyone wonders what happened to their traffic, visibility, or reach. The answer is pretty simple: you built on rented space instead of your own.
Reddit isn’t an authority in the way marketers usually mean when they talk about authority. Reddit can give you access to an authoritative, highly visible domain, but that domain’s authority doesn’t automatically transfer to your company. An AI citation means the information was useful or relevant enough to retrieve and not necessarily that your brand was endorsed as an expert.
We see an AI cite something and instinctively treat the citation like a recommendation, but citations and recommendations aren’t exactly the same thing. An AI saying something like, “several people have had good experiences with XYZ company” is vastly different than it saying “XYZ is the best company for your issue.” The former is data retrieval. The latter is a judgment. Citation isn’t necessarily an endorsement, recommendation, or proof a brand is the best choice.
Our research also found that review sites behaved differently from social media and community platforms. Rather than citations being overwhelmingly concentrated on one or two dominant domains, review-related citations were spread across a much broader collection of sites and aggregators. That data suggests the underlying mechanism is that AI needs useful information, so it retrieves that information from places where it exists. Reddit happens to be a very large place where useful information exists. So are YouTube, LinkedIn, Medium, and review sites like Yelp. Essentially, the platform label matters less than the underlying presence of useful information.
“Really what you have to think about is when do you rent the land? When do you borrow a platform and when do you own the content? I think that's the thing that people need to stop and think about. When it comes to the core messaging for your business, what you're good at, the questions you answer, the problems that you solve, you have to prioritize the land you own first and the platforms you borrow second.” -Tracy Graziani
It’s also important to note that our citation data was collected before Reddit’s latest access changes took full effect. Treat the platform mix, especially the Perplexity-to-Reddit relationship, as a snapshot of observed citations, rather than a permanent benchmark about how every engine will behave. Platform behavior is changing quickly and it’s worth paying attention to access restrictions, licensing agreements, and litigation. This is also another reason why you shouldn’t build your entire AEO strategy around one platform.
It’s incredibly important to understand how Reddit works before thinking about deploying a Reddit AEO strategy.
Reddit is a platform that has existed for 21 years, with 121.4 million daily active users across the globe. The user base is broadly recognized to be “offbeat, quirky, and anti-establishment.” Longtime users take site rules, moderation, and site etiquette very seriously. Reddit isn’t a social media platform in the way that many assume if their primary networks are Facebook or X, as much as it is a global discussion board. Users don’t care who someone is, but rather what they contribute to the conversation.
Substance, relevance, and accuracy take precedence over personal identity or brand. The vast majority of posts and replies are text-only; most users have no interest in networking, influencers have never really existed on Reddit, and, most importantly, promotion is heavily disliked. Redditors are acutely aware of when a brand is attempting to promote itself rather than offering actual insights and solutions.
Reddit threads operate on votes. Upvotes indicate something is relevant, useful, helpful, or entertaining, and the more upvotes a topic or comment has, the higher it will appear in the thread, subreddit, or homepage. Downvotes indicate something is off topic, breaking rules, spam, promotion, trolling, or poor quality. If something is downvoted enough, it’ll be collapsed in the comment thread and/or potentially removed by moderators.
Each Reddit user, orRedditor, also has a karma score, which is a digital score that shows the user’s reputation. It goes up when people upvote someone’s posts and comments, and down when they’re downvoted. The higher someone’s karma score, the more likely they’ll be considered a trustworthy source or authority. Earning good karma can be an incentive to post quality content that others find worthwhile.
Jumping into Reddit is like moving to a new neighborhood and having to integrate into the new community. There isn’t a way to manufacture upvotes or karma. You can’t network with people to post about you to get AI to cite your brand. You can’t advertise or promote in subreddits without being downvoted into oblivion. It takes time, interest, contribution, and effort to become established as a credible source on Reddit. In other words, you have to become an actual member of the platform.
“I think it's really smart that Reddit has gated AI access in the way that they have, because they want to have a quality user experience. Their users don't want a bunch of spammy stuff junking up their experience on their platform. If you're going to borrow the platform, you have to participate in it like a good citizen of that platform.” -Tracy Graziani
You should post on Reddit if your audience is actually there and you have something useful to contribute. Reddit can be a smart visibility tactic, but you shouldn’t be posting there just because people are saying Reddit is good for AEO. Posting on Reddit, LinkedIn, YouTube, or other platforms can absolutely be worth your time, but they need to be used with clear expectations.
If your buyers are asking questions there, pay attention. If people are comparing products in your niche, listen to what they’re saying. If you have genuine expertise that can help solve a problem, contribute it. If a relevant conversation gives you an opportunity to explain something better than existing answers do, add to the conversation. What isn’t particularly useful is trying to game Reddit for AEO citations. Apart from being a poor way to participate in the community and opening the floodgates to downvotes, it misses the larger opportunity of actual humans finding you helpful.
“Reddit is still a smart play when you consider that a lot of platforms are selling that data back to the LLMs, and so it’s training the overall corpus. So Reddit isn't a bad idea, and it also is affecting LLMs in a certain way, but it is definitely a distraction if you're trying to hack it. I feel like what we're going through with AEO right now is so much like the early days of SEO. Everybody's trying to game the system, and every time someone comes up with a hack, it eventually gets blocked by technology one way or another. Suddenly all of the gains that you had are lost. So far in the history of AEO, which is pretty short, the listicle has tanked; now the Reddit hack has tanked. It's going to keep happening, and so the real thing is to focus on Reddit when it makes sense.” -Tracy Graziani
Reddit, YouTube, and LinkedIn can put your ideas in places where AI engines are already looking. For some engines and audiences, that can be an important part of the path between a buyer’s question and your brand. But while visibility matters, these platforms shouldn’t be the sole foundation of your AEO strategy. Someone can see your company mentioned in a Reddit thread and never visit your website, watch your YouTube video and never subscribe, or read your LinkedIn posts and never become a lead.
Borrow the platform’s reach, but do something with it. Build a website worth visiting, create research people want to reference, and publish resources to answer real questions. Most of all, develop a relationship with customers and prospects. Give people a reason to remember your company after the Reddit thread disappears.
Chasing Reddit can be legitimate, but don’t confuse third-party assets with your own. Third-party platforms can change the rules at any time. Your content may remain valuable to people on the platform, but its availability to an AI engine can depend on contracts, crawler rules, and disputes entirely out of your control. Use the platforms for reach, but build your authority through the audience, expertise, and content you own.
