Reddit Self-Promotion Rules: The 9:1 Rule And What Actually Applies

Ask around what "the 9:1 rule" is and you will get a pile of different answers, and plenty of them will say it is a Reddit rule. It is not. It is a line from an old etiquette page, and the way it is used today is much looser than most guides claim. I checked Reddit's own pages before writing this, because I moderate seven subreddits and I am tired of watching businesses get removed for rules that do not exist while missing the ones that do.

Here is what is actually official, what is a rule of thumb, and what only your target subreddit decides.

Which Reddit Rules Actually Apply To Self-Promotion?

Three layers, and people constantly blur them.

1. The Reddit Rules. The platform-wide rules that apply to everyone and are enforced by Reddit's admins. Eight of them.
2. Reddiquette. Reddit's help center calls it an informal expression of the values of many Reddit users, as written by users themselves, and asks you to abide by it as best you can. It is guidance, not law.
3. Each subreddit's own rules. Reddit's rules page puts it directly: the culture of each community is shaped by the community rules enforced by moderators, and you are asked to abide by the rules of the communities you participate in.

Self-promotion is mostly governed by layer three, with layer one setting the outer boundary. If you remember one sentence from this page, make it that one.

What Are The Rules Of Posting On Reddit?

I opened Reddit's rules page and this is the list as it stands today. Numbering is Reddit's own.

The wording in the table is my paraphrase of Reddit's page, so read the original if you need exact language. Reddit's enforcement list includes asking nicely, asking less nicely, suspending accounts, adding restrictions to accounts, and removing content.

What Is Rule 1, 3, 7 Or 8 On Reddit?

People ask "what is rule 7 on Reddit" all the time, and the answers online contradict each other for a simple reason. There are two completely different numbering systems.

So when somebody says "my post broke rule 3", the first question is: which subreddit? In most cases they are quoting the removal message from a community, and the number refers to that community's list. Sitewide, rule 3 is privacy, rule 7 is legality and rule 8 is not breaking the site, as the table above shows.

I cannot tell you what the old numbering looked like in earlier years, because I only verified today's page. If a forum thread quotes a different list, check the date on it.

What Is The 9:1 Rule On Reddit?

The source is reddiquette. The exact line, from Reddit's help center page: feel free to post links to your own content, within reason. If that is all you ever post, or it always seems to get voted down, take a good hard look in the mirror, because you just might be a spammer. "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."

Three things to take from that:

• It is a rule of thumb inside an informal guide, not a sitewide rule with a penalty.
• It talks about submissions, meaning posts, not comments.
• It is described as "widely used", and reddiquette itself was written by users, so it reads as a community habit rather than an admin rule.

Reddit's newer moderator-facing help page confirms the idea survives, but as a choice. In its article on keeping spam out of a community, Reddit says that promotional content is not inherently considered to be spam, that some communities disallow any promotion, and that others abide by a 10% rule: only 10% of your posting and comment history in that community can be self-promotional, with the other 90% helpful, organic content. Reddit adds that it is ultimately up to the mod team to decide what works for their community.

Notice the small shift. The old line counts posts. The newer one counts posting and comment history inside one community. Neither is enforced by a counter anywhere that I can find in Reddit's docs, so treat both as a standard moderators will apply by eye.

What Is The 90-9-1 Rule?

A different idea with a confusingly similar name. The 90-9-1 rule comes from Nielsen Norman Group's article on participation inequality: in most online communities, 90% of users are lurkers who never contribute, 9% contribute a little, and 1% account for almost all the action. It describes how people behave, not what you are allowed to post. It is not a Reddit rule and has nothing to do with the 9:1 content ratio.

It is still useful to marketers. It tells you that a thread with 20 comments was read by many more people than commented, which is the reason I judge a post by views and saves, not just replies.

What Does Reddit Count As Spam?

The sitewide spam policy defines spam as repeated or unsolicited actions, automated or manual, that negatively affect users, communities or Reddit itself. Its examples include mass-posting repetitive content for exposure or financial gain, mass-tagging, and using tools such as bots or generative AI tools that facilitate the spread of spam.

Then comes the passage that matters for businesses. To avoid being labeled a spammer, Reddit says: post authentic content in communities where you have a personal interest. If your contributions consist primarily of links to a business you run, own or otherwise benefit from, be thoughtful about how often you post, or consider advertising through the self-serve platform. And check whether the community has its own rules, because moderators adjudicate what counts as unwanted or spammy in their communities.

Read that again. The policy does not ban business accounts. It bans a pattern: links to your own thing, repeated, with nothing else.

How To Self-Promote On Reddit Without Getting Removed

What I do in my own communities, and what I would tell any business:

• Read the rules and search the wiki first. Some communities ban promotion outright. Others have a weekly self-promo thread. Many allow it with a ratio.
• Contribute before you mention anything. Weeks of useful comments beat any clever post. It also helps with the reputation and Crowd Control filters, which hold back accounts that look risky or are not yet trusted in that community, as I explain in why posts get removed.
• Disclose who you are. Rule 5 targets deception. A profile that says who you work for removes the deception.
• Answer the question first, link second. If a link is the whole answer, it is an ad.
• Ask mods for permission. A two-line modmail is cheap, and some will point you to the right thread.
• Own a community. Where you are the moderator, you set the promotion policy. That is the long-term answer.

My takeThe 9:1 maths is the least important part. I would rather see a business post one honest, useful thread a week with a visible disclosure than hit a perfect 90% ratio with comments written to disguise who is talking.

How Moderators Enforce It

Moderators use AutoModerator, which can remove links by domain or keyword (Reddit lists affiliate links as an example), and safety filters like the reputation filter. Read my AutoModerator guide to see how those rules are written. As a mod, a post that reads like marketing bothers me far more than one that merely contains a link, because the link is just the symptom.

Running a giveaway is separate again. Reddit's promotions guidance says you are responsible for the promotions you run, requires clear official rules, and says lotteries are not allowed without Reddit's explicit permission. Do not improvise a contest in a comment thread.

Shortcuts That Backfire

I get asked about all of these. I do not do any of them, and neither should you.

• Second accounts to post praise. That is exactly what rule 5 is about, and it also runs into Reddit's spam policy, which names multiple accounts used to inflate a subreddit's subscriber count.
• Buying karma or accounts to clear thresholds. It is content manipulation under rule 2 and moderators spot it.
• Pretending to be a customer. Invented stories get found out, and a brand never recovers its credibility on Reddit.

The white-hat route is slower and it compounds. A disclosed account, a real contribution history and, for a business that wants this done properly, a branded community with its own rules. That is the brand subreddit service, and the broader frame is in my Reddit marketing guide.

Questions About Reddit Self-Promotion Rules

What is the 9:1 rule on Reddit?

It is a rule of thumb from reddiquette, Reddit's informal etiquette page: only 1 out of every 10 of your submissions should be your own content. It is guidance, not a sitewide rule, and each subreddit decides what it enforces.

Is the 9:1 rule an official Reddit rule?

No. It appears in reddiquette, which Reddit describes as an informal expression of community values. Reddit's moderator help page also mentions a 10% rule that some communities choose to follow, and says it is up to each mod team.

What is the 90-9-1 rule?

It is Nielsen Norman Group's participation inequality principle: roughly 90% of users lurk, 9% contribute a little and 1% account for most activity. It is unrelated to the 9:1 self-promotion guideline.

Can a business post on Reddit at all?

Yes. Reddit's help center says promotional content is not inherently considered spam, but some communities forbid it. Follow each community's rules, be authentic and disclose who you are.

What is rule 7 on Reddit?

Sitewide, rule 7 is Keep it legal. But people often mean rule 7 of a specific subreddit, which moderators set themselves and which can say anything, including no self-promotion.
