Why your Reddit marketing dies in 90 days
Most brands trying to market on Reddit get banned, shadow-banned, or downvoted into silence within 90 days. The reason isn't the comments. It's the account.
Most brands that try to market on Reddit are gone in 90 days.
Not gone as in "they decided it wasn't working." Gone as in the account is shadow-banned, the comments are invisible to everyone but the person logged into that account, and nobody at the company has noticed yet.
This piece is about why that happens. It happens for a specific, mechanical reason. And the reason is not the quality of the comments.
The pattern that kills the account
Here is the pattern we see, almost every time:
- Someone at the company (or the agency they hired) creates a new Reddit account.
- They search for threads mentioning their product category.
- In the first week, they leave eight or ten comments. Most mention the brand. Some include a link.
- By week three, the account has stopped showing in threads.
- By week six, someone finally logs out, looks at the account from a different browser, and realizes nobody can see the comments at all.
The account is not banned in the obvious sense. There is no email. No warning. No red banner.
It is shadow-banned. The comments still appear when the account-holder is logged in. They do not appear to anyone else. The thread looks the same to the marketer as it did the day they posted. The work is invisible.
What Reddit is actually watching
The instinct after this happens is to blame the comments. Maybe they were too promotional. Maybe the language was off. Maybe the link was the problem.
The comments are almost never the problem.
Reddit's spam detection is watching two things, and content is not really one of them:
1. The ratio of helpful comments to promotional comments on the account. Not on the post. On the account.
2. The age and history of the account. A six-year-old account with 4,000 karma posting one product mention reads differently than a six-week-old account doing the same thing.
These two signals run silently in the background, and they decide whether a comment shows up to the rest of Reddit or gets quietly suppressed. The content of the individual comment matters way less than most marketers assume.
The four-to-one rule
The first lever you can pull is the ratio.
For every comment that mentions the brand or links to anything you sell, there should be at least four comments that do not. These are helpful comments. Replies to questions in your industry. Corrections to bad advice. Sharing of expertise that has nothing to do with the brand.
This is the ratio Reddit's systems are watching. Four-to-one is the floor. Some operators run six-to-one or ten-to-one to be safe.
The ratio does more than keep you out of the ban range. It earns the right to be heard. An account whose history is 80% genuinely useful comments reads, to humans and to algorithms, like a person who happens to work in the industry. An account whose history is 50% promotional reads like a marketing account, because that is what it is.
What a Reddit account that survives actually looks like
- Helpful comments, no brand mention80%
- Comments that mention the brand20%
An account that runs closer to 50/50 reads as a marketing account and gets shadow-banned. Four-to-one is the floor; some operators run six- or ten-to-one.
Most brands break this rule in the first week. They sit down to "do Reddit marketing" and the only comments they leave are the promotional ones. The ratio is already broken by day seven.
A four-to-one ratio of helpful comments is what makes the one brand comment survive. Skip the helpful comments and the brand comments get suppressed before anyone reads them.
The thirty-day cold start
The second lever is account age.
A brand-new Reddit account posting in product-mention threads triggers spam detection at higher sensitivity. The system has no history to weigh against. It treats the account as guilty by default, until enough non-promotional behavior accumulates.
This is the cold-start problem, and it has a thirty-day fix.
If the person commenting for your brand is using a brand-new account, the first thirty days should be helpful comments only. No brand mentions. No links. No "I work at." Just useful answers in the subreddits where your category lives.
After thirty days of that, the account has the history it needs. The brand comments, when they start, will not be the first thing the spam system sees from this user.
This step is the one that gets skipped most often, and it is the one that costs the most when it gets skipped.
The voice problem
The third lever is how the comment sounds.
Reddit can tell when a comment is written by the brand and when it is written by a person who happens to work at the brand. The difference reads instantly. Mods can spot it. Other users can spot it. The spam systems are tuned for it.
A few quick tests:
- Does the comment start with "We at [Brand]..." or "Our team..."? That is a brand voice. It will get downvoted. Rewrite as "I work at..." or just answer the question and mention the company once, casually, near the end.
- Does the comment read like a press release? That is a brand voice. Rewrite.
- Would the person posting it say it that way out loud, on a phone call with a friend in the industry? If no, rewrite.
The accounts that survive are the ones that sound like a real human who happens to be in the industry. Not the corporate communications department.
The link rule
The fourth lever is the simplest. It is also the one most people get wrong.
Most subreddits auto-remove comments that contain outside links. The auto-removal is silent. The commenter never sees a notice. The thread looks normal from their perspective.
The right place for the brand's link is the Reddit profile bio. It sits there permanently. The people who care about who you are will click. The people who don't, won't.
If a subreddit specifically allows links and the link is the most useful thing you can offer, then a link in a comment is fine. Those situations exist but are rare. The default move is to leave the link in the bio and skip it in the comment.
What to do if the account is already burned
If you read this and recognized your own account, here is what to do.
The burned account is not coming back. Reddit's spam scoring on accounts that have been flagged tends to stick. You can keep posting from it, but the comments are likely to keep getting suppressed.
The move is to start a new account, slowly, and follow the cold-start protocol from the top. Thirty days of helpful comments. Four-to-one ratio after that. Voice that sounds like a person.
This is slower than most agencies want it to be. It is also the only version that works.
Why this is worth the discipline
A Reddit account that survives a year of this discipline is doing something most brand accounts can never do.
The comments stay live, indexed by Google, indexed by Reddit's own search. Six months later, the comment is still there. Twelve months later, the AI models that license Reddit's content are training on it. Eighteen months later, the comment is one of the sources ChatGPT or Perplexity or Google AI Overviews pulls from when someone asks a question your brand has a real answer to.
That is the payoff. Not the comment that went up today. The comment that is still there a year from now, doing slow, compounding work in the background.
For the broader picture of why Reddit threads end up cited in AI search answers, we wrote about that in Reddit is where ChatGPT learns about your brand. And if the bottleneck right now is finding the right threads to comment on without losing a workday to scrolling, Reddit Brand Monitor is the tool we built for that part. Our teammate Maya wrote up the free, by-hand version too, a full walkthrough on how to find leads on Reddit for free.
What we tell clients
When a brand comes to us asking about Reddit, the conversation almost always starts with one of two things. Either they tried it and the account died, or they have not tried it yet and they want to know if it is worth the effort.
The answer is the same in both cases.
It is worth the effort, but only if the brand is willing to do the slow version. The fast version is the version that gets banned in 90 days. There is no faster version that survives.
If the brand has someone real at the company who is willing to be on Reddit for the next year, behaving like a useful person in the industry, with the four-to-one discipline, then the work pays off in a way that is hard to get from any other channel.
If that person doesn't exist at the company, the answer is to do something else. We will tell a brand to skip Reddit before we will sell them a campaign that's going to burn their account.
