Reddit's self-promotion rules come down to one principle: contribute far more than you promote. The best-known guideline is the 9:1 rule, which suggests no more than 1 in every 10 of your posts should be your own content. But that is informal etiquette, not a rule Reddit enforces. What Reddit actually enforces is authentic participation, no spam or manipulation, and each subreddit's own rules.
Getting this right is the difference between Reddit being your highest-trust channel and getting your account filtered or banned. Here is what the rules actually say, and how to stay on the right side of them.
The 9:1 rule, explained
The 9:1 rule lives in Reddit's Reddiquette, which states: "A widely used rule of thumb is the 9:1 ratio, i.e. only 1 out of every 10 of your submissions should be your own content." Reddit's older self-promotion guidance frames the same idea as "10% or less of your posting and conversation should link to your own content."
Two things matter here. First, Reddiquette calls itself "an informal expression of the values of many redditors," so the 9:1 ratio is community etiquette, not an enforced sitewide rule with a counter running in the background. Second, the spirit behind it is the real rule. Reddit's self-promotion guidance puts it memorably: "it's perfectly fine to be a redditor with a website, it's not okay to be a website with a reddit account." Treat 9:1 as a sanity check on your behavior, not a threshold to game.
The rules Reddit actually enforces
Three things, working together, are what get an account actioned:
- Reddit Rule 2. Reddit's sitewide rules require you to "participate authentically in communities where you have a personal interest, and do not spam or engage in disruptive behaviors (including content manipulation) that interfere with Reddit communities."
- The spam policy. Reddit's guidance is direct: "Post authentic content into communities where you have a personal interest. If your contributions to Reddit consist primarily of links to a business that you run, own, or otherwise benefit from, please be thoughtful about the frequency of posting, or consider advertising opportunities using our self-serve platform."
- Each subreddit's own rules. Communities set rules on top of the sitewide ones, and Reddit is explicit that "community moderators adjudicate what constitutes unwanted/spammy content in their communities and may take action accordingly."
None of these mentions a 9:1 or 10% ratio. The enforceable standard is authentic participation, not a number.
How to promote without breaking the rules
Staying compliant is mostly common sense applied consistently. Lead with genuine contribution: answer questions where you have real expertise, and let helpful comments do more work than posts. Read the sidebar and rules of every community before you post, and when a post is clearly self-promotional, be transparent about your affiliation. Keep your own links a small share of your overall activity, which is the practical version of the 9:1 idea. For the full playbook on doing this at scale, see our guide on how to promote on Reddit.
What happens if you break them
Enforcement is a ladder, not a single switch. Per Reddit's enforcement policy, "certain violations give rise to an immediate permanent ban," while for others "a user may first receive a warning, followed by a 3-day ban, 7-day ban, and then a permanent ban." If your account is actioned by mistake, you can "submit an appeal within six months."
The margin for sloppy self-promotion is also shrinking. In a July 2026 update, Reddit said it is now "blocking 23 million spam views per day before they ever reach a human user." Tactics that slipped through a few years ago are increasingly caught early, so the safe path is also the effective one.
Frequently asked questions
What is the 9:1 rule on Reddit?
The 9:1 rule is a guideline from Reddit's Reddiquette suggesting that no more than 1 in every 10 of your submissions should be your own content. It is informal community etiquette, not an enforced rule, and its point is to make sure you contribute far more than you promote.
Is self-promotion allowed on Reddit?
Yes. Promotion is fine as a minor part of authentic participation. Reddit's rules target accounts that exist mainly to push a business, and each subreddit can set stricter limits, so contribute value first and link sparingly.
Does Reddit actually enforce the 9:1 rule?
No. Reddit enforces Rule 2 (authentic participation, no spam or manipulation), its spam policy, and each subreddit's own rules. The 9:1 ratio is etiquette, not a threshold Reddit tracks, so an account that only ever links its own business is a spammer regardless of the exact ratio.
Can you get banned for self-promotion on Reddit?
Yes, if it crosses into spam or manipulation. Many violations follow a ladder of a warning, then a 3-day ban, then a 7-day ban, then a permanent ban, while serious abuse can trigger an immediate permanent ban. Banned accounts can appeal within six months.
