How to promote your product on Reddit without getting banned

Reddit is the best and most dangerous distribution channel for a small product. Best, because a single genuinely helpful post can send you hundreds of the right users. Dangerous, because the moment you smell like marketing, you get removed, downvoted, and sometimes shadowbanned — and you won't even know. Here's how to promote your product on Reddit the native way, without getting banned.

Understand what Reddit actually punishes

Reddit doesn't hate businesses. It hates extraction — people who show up only to take attention and give nothing. The unwritten rule most people cite is the 90/10 guideline: at least 90% of your activity should be genuine participation, and at most 10% should ever mention your product. Communities can smell an account that only posts about itself instantly.

So the goal isn't “how do I sneak my link in.” It's “how do I become a real member who occasionally has something relevant to share.”

Value first, always

Every post you make should give the reader something even if they never click anything. Teach a lesson, share a real result, tell a story with a specific takeaway. If you removed all mention of your product, the post should still be worth reading. If it wouldn't be, it's an ad, and Reddit will treat it like one.

Explain the reasoning, not just the answer

Native Reddit writing explains why something works — the system behind the answer — not just that it works. Compare:

Marketing: “You should use caching! Our tool handles this automatically. Learn more here [link].”
Native: “This breaks because you're rebuilding the whole tree on every render. The fix is to memoize the expensive part so children only recompute when that specific value changes. React can't know your data shape, so you have to tell it.”

The native version earns trust because it teaches. Every sentence adds information — no gloss, no padding.

The link goes in the comments

This is the single most important tactic: keep your link out of the post body. Post the value, and if the product is genuinely relevant, mention it plainly in a comment — “I actually built a small tool for this, happy to share if useful.” This does two things: it satisfies the algorithm (external links in the body suppress reach) and it satisfies the community (you led with value, the product is an afterthought).

Match the subreddit's register

Every subreddit has its own culture. A post that kills in r/SideProject would get eaten alive in a strict technical sub. Read the top posts before you post. Match the tone — peer-to-peer in technical communities, plainer and friendlier in casual ones. Read the rules, actually. Many subs ban self-promotion outright, and posting anyway is the fastest way to a ban.

Build history before you need it

A brand-new account that immediately posts about a product is a red flag. Spend a couple of weeks genuinely participating — answering questions, sharing what you know — before you ever mention what you're building. Karma and history are trust, and trust is what lets you get away with the occasional product mention.

What to never do

• Don't drop the same post across ten subreddits — that's spam and it's obvious.
• Don't use a throwaway account to promote; it fools no one.
• Don't argue with people who call you out; you'll lose.
• Don't post where your reply would need a link to be useful at all.
• Don't fake being a “happy customer” of your own product. It always surfaces.

The mindset that keeps you safe

The founders who win on Reddit stopped thinking about it as a marketing channel and started thinking about it as a community they're part of. The product mentions become natural because they're rare and relevant. If you write every Reddit post to be genuinely useful first, you almost can't get banned — because you're doing exactly what the platform wants.

This is also why generic AI can't write your Reddit posts: the native, non-promotional, community-specific voice is the whole point. If you want help drafting Reddit posts that stay value-first and keep the link in the comments, that's one of the things postship does — right alongside repurposing your other content.
