- Reddit has no single self-promotion rule, only a sitewide spam policy plus each subreddit's own rules
- The historical 9:1 ratio is gone from official docs but mods still use it as a mental benchmark
- Mods tolerate promotion from people who participate; they ban drive-by link droppers on sight
- A two-line modmail asking permission before you post converts surprisingly often
There is no single "Reddit self-promotion rule." There are three layers: Reddit's sitewide spam policy, each subreddit's own rules, and the personal judgment of the mods enforcing them. If you understand all three, you can promote on Reddit without ever getting banned. Most founders only read the first layer, then wonder why their post vanished.
The stakes justify the effort: Google pays Reddit roughly $60M a year to license its threads (their 2024 deal), and public citation studies put around 40% of AI-cited sources on commercial queries on Reddit. A banned account locks you out of all of that. Here's how to decode each layer, where the famous 9:1 ratio came from, and the exact messages that get mods to say yes.
What does Reddit's sitewide spam policy actually say?
Reddit's Content Policy bans "spam and content manipulation": posting the same link repeatedly, using bots or bought upvotes, running networks of accounts that promote the same thing, and evading bans with new accounts. That's the sitewide floor. Break it and you're dealing with Reddit's admins, not mods, and the outcome is usually an account suspension or a shadowban.
Notice what the sitewide policy does not say: it doesn't ban self-promotion. Posting your own product is allowed at the platform level, as long as you're transparent about your affiliation and you're not manipulating votes or spraying the same link across ten subreddits in an hour.
The practical takeaway: sitewide rules punish patterns, not individual posts. Reddit's own help page on what constitutes spam frames it the same way. One honest post about your product almost never triggers admin action. Thirty identical comments in a week absolutely will.
Where do you find each subreddit's self-promotion rules?
Every subreddit writes its own rules, and they override anything you assume from the sitewide policy. Before posting anywhere, check four places:
- The rules sidebar (on desktop, right column; on mobile, the "See community info" tab). Look for rules named "No self-promotion," "No advertising," or "Promotion guidelines."
- The subreddit wiki, often at
reddit.com/r/<sub>/wiki/rules. Some communities hide the detailed version here. - Pinned posts. Many subs run a monthly "promote your stuff here" thread. If one exists, that thread is usually the only sanctioned place for links.
- Recent removed posts. Search the sub for posts like yours and see which survived. Five minutes of reading tells you more than the rules page.
How to read the rules: "No self-promotion" rarely means zero, in practice it means "no low-effort self-promotion." A sub that bans link posts often tolerates a text post where the product is mentioned in context. Ambiguous wording is intentional: it gives mods room to keep good contributors and remove lazy ones.
Is the 9:1 rule still a thing?
The 9:1 ratio comes from Reddit's old official self-promotion guideline, which was retired years ago but never left the culture.
Reddit's original self-promotion FAQ suggested that if more than roughly 10% of your submissions were your own content, you were probably a spammer. In other words: keep self-promo under one post in ten. The page is gone, but thousands of mods internalized it, and many subreddit rules still cite "the 10% rule" by name.
So treat 9:1 as a cultural norm, not a law. What it means today:
- Your profile is your résumé. Mods click your username before deciding on a removal. If your history is 90% genuine participation, comments, answers, discussions, your one promotional post reads as a contribution.
- The ratio is judged per account, not per subreddit. Helping people in r/startups builds credibility that carries into r/SaaS.
- New accounts fail the test by default. A 3-day-old account with one post (yours) is 100% self-promotion. That's the profile mods remove without reading.
In our experience, the founders who never get banned aren't the ones counting posts to hit exactly 9:1. They're the ones who'd still be active on Reddit if their product didn't exist.
What do mods tolerate vs. instantly ban?
Mods are volunteers protecting a community they care about. Their real question isn't "is this promotional?" but "does this person make my sub better or worse?"
| Mods generally tolerate | Gets you banned on sight |
|---|---|
| Mentioning your product inside a genuinely useful answer, affiliation disclosed ("full disclosure, I built this") | Drive-by link drops from an account with no other history in the sub |
| A detailed lessons-learned post where the product appears as context, not as the pitch | The same comment pasted across multiple threads |
| Answering when someone explicitly asks for tool recommendations | Fake "just discovered this amazing tool!" posts from the founder's account |
| Posting in the designated monthly promo thread | Asking a friend (or an alt) to post it "organically", that's vote manipulation, the fastest route to a sitewide suspension |
| Taking a removal gracefully and reposting elsewhere | Arguing with a mod after a removal |
The pattern is obvious once you see it: effort plus disclosure gets tolerated, laziness plus disguise gets banned. For the day-to-day system that keeps accounts safe, see our guide to Reddit marketing without getting banned.
How do you ask a mod for permission?
When rules are ambiguous, message the mods before posting. It takes two minutes, and a "yes" in writing is the best insurance a removal appeal can have. Use modmail (the "Message the mods" button), keep it short, and make refusing easy.
A formulation that works:
"Hi mods, I'm the founder of a small tool for [audience]. I wrote a post about [specific lesson/topic] that mentions it once, with disclosure. Would that be OK here, or would you prefer I keep it to the monthly thread? Happy to adjust or skip it."
Why this works: it discloses upfront, shows you read the rules (you know about the monthly thread), and offers them an out. We sent a version of this exact message to the r/EntrepreneurRideAlong mods before publishing a build-in-public breakdown that mentioned our tool once. A mod answered the same day: post it, keep the disclosure in the first paragraph, drop the link in a comment only if someone asks. The post stayed up, and the next ask to the same modmail got a yes in minutes. Two more tips:
- Ask about a specific post, not blanket permission. "Can I promote here sometimes?" gets ignored. "Is this exact post OK?" gets answered.
- If they say no, thank them and participate anyway. Mods remember usernames. A gracious no today often becomes a yes in three months.
Finding which subreddits and threads are worth this effort is the harder problem, that's the part we obsess over at Readyt: surfacing the threads where a disclosed, useful mention actually pays off. For the full posting strategy once you have permission, read how to promote on Reddit.
FAQ
Is self-promotion allowed on Reddit?
Yes, at the platform level. Reddit's sitewide policy bans spam and vote manipulation, not self-promotion itself. Each subreddit then sets its own stricter rules, so the real answer depends on where you post. Always check the sidebar rules and pinned threads before sharing your own links.
What is the 9:1 rule on Reddit?
It's the retired official guideline suggesting no more than about 10% of your activity should promote your own stuff. Reddit removed the page, but many mods and subreddit rules still enforce the spirit of it: participate nine times more than you promote, and your account reads as a contributor.
What happens if you break a subreddit's self-promotion rules?
Usually escalation: first your post gets removed, then you get a warning or temporary ban, then a permanent subreddit ban. Repeat offenses across subreddits can trigger admin action, including a shadowban where your posts become invisible to everyone but you. One polite modmail after a removal can often reset the clock.
Should you tell people it's your product?
Always. Disclosure ("I built this") is the single cheapest trust signal on Reddit. Mods tolerate disclosed founders far more than disguised ones, and undisclosed promotion that gets outed usually ends in a ban plus public embarrassment in the comments.
