The Reddit 9:1 rule is a rule of thumb, not a Reddit policy. It comes from Reddiquette, the user-written etiquette page, which says only about one in ten of your submissions should be your own content. No moderator has to honor it or is bound by it. Your real limits are each subreddit's written rules, which are usually stricter, and Reddit's spam systems.
So treat 9:1 as a floor for your habits and a ledger you keep, not a permission slip. This guide covers where the idea came from and what it does and does not cover. It shows how to count it per account and per subreddit, with a worked example, how moderators enforce limits, and what to do in communities that ban promotion outright. The rules quoted below were read from Reddit on 3 November 2026. They change, so check the live rules before you post.
Key takeaways
- The 9:1 rule comes from Reddiquette, Reddit's informal guideline page. It covers your own content in submissions, not comments or "promotion" in general.
- Reddit's site rule is broader and vaguer: take part authentically in communities you care about and do not spam. Each subreddit then sets its own limit.
- Many subreddits set a tighter cap than 9:1 or ban promotion outright. r/SaaS allows one mention or three links per 60 days. r/sales bans selling entirely.
- Count contributions and promotions per account and per subreddit. A healthy overall ratio can hide a subreddit where you have never contributed anything.
- If you delete the product line from a promotional comment, it should still be useful. That test beats any ratio.
- In no-promotion subreddits, don't look for a cleverer workaround. Contribute without a pitch, use the sanctioned weekly threads, or pay for ads.
Where the 9:1 rule comes from
The only Reddit-published source we could find for the ratio is Reddiquette, which calls itself an informal expression of the values of many Reddit users, written by users. Under "Please do," it says to feel free to post links to your own content, within reason. Then it adds that a widely used rule of thumb is the 9:1 ratio: only 1 out of every 10 of your submissions should be your own content.
Three details in that sentence matter for marketers.
- It covers submissions, meaning the posts you make, not comments. The text says nothing about how to count a product mention inside a comment.
- It covers your own content. A link to your blog post counts. A reply that never links anywhere but pushes your product by name isn't covered by the wording at all, and subreddit rules had to fill that gap.
- It describes a norm, not an enforcement mechanism. Reddiquette is a guideline. Moderators can cite it, but they can also set a stricter limit or none at all.
We couldn't find a separate, official Reddit policy that sets a "10% self-promotion" number. When you see that figure quoted, it's the same Reddiquette line seen from the other side: one promotional item in ten. We also couldn't retrieve Reddit's spam policy page when we wrote this (it blocks automated requests), so we don't quote it here.
People also mix up the 9:1 rule with the "90-9-1 rule." That one comes from Jakob Nielsen in 2006, published by Nielsen Norman Group, and says that in online communities about 90% of users only read, 9% contribute a little, and 1% produce most of the content. It's about participation inequality and says nothing about how often you may promote.
How the 9:1 rule differs from Reddit's rules and each subreddit's rules
Five separate things limit what you can post, and different people set them.
The first is Reddit's sitewide rules. Reddit Rule 2 says to abide by community rules, participate authentically in communities where you have a personal interest, and not spam or engage in disruptive behavior, content manipulation included. Rule 5 asks you not to intentionally mislead others. Neither contains a ratio.
Second come Reddit's help pages on disruption. Reddit's policy on disrupting communities prohibits vote manipulation, including creating and using multiple accounts to manipulate vote counts. It also counts two patterns as community disruption: being repeatedly reported for breaking community rules across several communities, and being banned across several communities that deal with the same topics. The second one catches marketers who get removed in five related subreddits in a month.
Third is Reddiquette, the source of the 9:1 line, as above.
Fourth are each subreddit's rules. Volunteer moderators write and enforce them, and they hold the real numbers. As read on 3 November 2026:
| Subreddit | What the rules say about promotion |
|---|---|
| r/SaaS | "Max 1 mention or 3 links can be shared every 60 days." Affiliation must be disclosed at the start or end. Secondary accounts promoting the same product count toward the limit. Violation "leads to a ban and URL blacklisting." |
| r/startups | No direct sales, advertisements or promotional posts of any kind outside designated stickied threads. "Self-promotion is anything you have an interest, stake or relationship with," which the rule says includes being friends with someone at the company. |
| r/B2BSaaS | Self-promotion must add value and is limited to one post per project or domain every 10 days. Astroturfing, meaning fake posts, shill accounts and coordinated promotion, earns a permanent ban. |
| r/smallbusiness | No business promotion posts outside the weekly thread. A relevant mention in a reply is allowed, but "deliberate abuse of this exception" is removed. As of June 2026, product mentions that look directly or indirectly promotional are removed. |
| r/devops | Self-promotion goes in the weekly thread. Any affiliation must be disclosed at the top of a post or comment. If promoting is your sole purpose in the subreddit, the rule says they do not want it. |
| r/msp | Promotion of any product, webinars included, must stay in the Weekly Promo thread. Vendors are asked to identify themselves by username or vendor flair. Posting requires 50 comment karma inside the subreddit. |
| r/sysadmin | Vendors may discuss their product in the context of an existing discussion and must disclose. Posting articles from your own blog is treated as a product. |
| r/sales | "No Selling or Self Promotion," with an immediate permanent ban. Company-branded accounts are prohibited from posting or commenting. |
| r/indiehackers | Self-promote a product one time, using the Self Promotion flair. |
| r/cybersecurity | All promotion must be under 10% of your posts and comments in the subreddit and no more than once a week per promoted entity. The rule says to be a community member first and self-interested second. |
| r/webdev | No excessive self-promotion, and the rule tells posters to refer to the Reddit 9:1 rule. Commercial promotion is banned, and project feedback requests are limited to Showoff Saturday. |
Only two subreddits in that table write anything like 9:1 into their rules. r/webdev points posters at the 9:1 rule, and r/cybersecurity caps promotion at 10% of your activity there, with a weekly limit on top. The rest write caps, weekly threads and bans. When a moderator in r/SaaS looks at your account, a clean overall ratio won't save you if it includes your second mention in 60 days.
Fifth are automated gates. On top of the written rules, many subreddits use AutoModerator or similar tools to block posts from accounts that are too new or have too little karma. The r/msp requirement above is one published example, and plenty of others go unpublished. We list the ones we could read in our guide to getting karma on Reddit, and the post rule checker reads a subreddit's current rules against your draft.
What counts as a contribution and what counts as promotion
Ratios fail when nobody agrees what goes in which column. Two tests settle it.
- The first is a benefit test. If you, your employer, your client or a friend benefits from someone reading it, it is probably promotion. r/startups puts it directly: self-promotion is anything you have an interest, stake or relationship with.
- The second is a delete test. Take the product mention or link out of your comment. If what's left is still a full, useful answer, the mention was incidental, and the comment is a contribution that happens to disclose a product. If the comment collapses, it was an ad. One commenter on an r/SaaS thread about this put it more sharply: moderators "check if the comment still stands with the product line deleted, and 90/10 fails that" (a r/SaaS commenter, 15 September 2026).
Here is how common actions sort:
| Action | Counts as | Why |
|---|---|---|
| Answer a question in full, no link, no product | Contribution | You gave something away and benefit nowhere |
| Share a workflow or a number from your own work | Contribution | Specific, checkable, useful alone |
| Honestly recommend a competitor when it fits | Contribution | The reader benefits and you do not |
| Correct a wrong claim and explain why | Contribution | Adds information |
| Mention your product, disclosed, because it directly answers the question | Promotion (the "1") | You benefit, even if the answer is also true |
| Link to your blog post, even a free one | Promotion | It is your own content, which is exactly what Reddiquette counts |
| Post a launch announcement or ask for feedback on your product | Promotion | Same rule, bigger footprint |
| Reply to people who commented on your own launch thread | Neither | It maintains the promotion. Do not count it as a contribution |
| "This" or "great post" | Nothing | Filters and moderators ignore it, and you should too |
| Upvotes | Nothing | They cost nothing and do not count toward standing |
Two edge cases come up constantly. A blog post that never mentions your brand is still your own content, so it goes in the "1" column. r/sysadmin says outright that posting articles from your own blog counts as a product. And a comment that answers fully, then ends "disclosure: I work on X", is still promotion if X is relevant to the question. Disclosure makes it honest. It doesn't make it free.
How to apply the ratio per account and per subreddit
Keep a ledger for every account that posts for the brand, with one row per action, counted over a rolling 30 days.
The formula for a window is simple:
Promotional actions you may add = floor(contributions in the window ÷ 9) − promotional actions already used
Then apply whichever is smaller: that number or the subreddit's own cap. Run the calculation twice, once for the account overall and once inside each subreddit you want to promote in, because standing is local. A moderator who opens your profile looks first at what you have done in their community.
| Contributions in the window | Promotional actions 9:1 would allow | Promo share of all actions |
|---|---|---|
| 9 | 1 | 10% |
| 18 | 2 | 10% |
| 27 | 3 | 10% |
| 45 | 5 | 10% |
| 90 | 10 | 10% |
Then the cap. In r/SaaS, 45 contributions still earns you one mention in 60 days. In r/startups it earns you nothing outside the sticky thread. The ratio decides whether you have earned the right to promote. The subreddit rule decides whether you are allowed to.
A worked ledger
This example is invented to show the arithmetic, not taken from client data. Imagine the founder of a made-up invoicing tool using one account for 30 days.
| Subreddit | Contributions | Promotions | Local ratio | What the rules allowed | Check |
|---|---|---|---|---|---|
| r/smallbusiness | 18 | 0 | n/a | Mentions only when directly relevant, otherwise the weekly thread | Fine. Zero promotions is the safe default |
| r/SaaS | 12 | 1 | 12:1 | One mention per 60 days, disclosed | Fine, but the 60-day clock now runs |
| r/B2BSaaS | 9 | 1 | 9:1 | One post per project every 10 days | Fine, exactly at the line |
| r/startups | 6 | 1 | 6:1 | Share Your Startup sticky thread only | Allowed by the rule, thin by the ratio |
| Total | 45 | 3 | 15:1 | 9:1 would allow 5 | Overall looks healthy |
At 15:1 overall, the account is comfortably above the line. The lesson is in the r/startups row. The rule allowed the post, since the Share Your Startup thread exists for it. But six contributions is a thin record in a community where this account then promotes, and it would look much better with eight more useful answers there first. The ledger caught what the overall number hid.
Notice also what the founder did not do. They never mentioned the product in r/smallbusiness, because the rules there remove promotional mentions, and a removal on the account's record would have gained it nothing.
Brand accounts and personal accounts
Every account keeps its own ledger. Moving promotion onto a second account to stay under the ratio is the most common way teams fail, and it breaks rules directly: r/SaaS says secondary accounts promoting the same product count toward the limit, and r/B2BSaaS bans coordinated promotion. For when a company handle makes sense and when a person should post, see brand account vs personal account on Reddit.
How moderators actually enforce limits
You are judged in layers, and most of them run before a human looks.
Automated filters come first. Reddit says it auto-collapses comments it detects as likely spam or low quality and shows them to moderators as "Potential Spam" (Reddit mod help). Each subreddit's AutoMod rules then apply the karma, account-age and keyword gates its moderators wrote. Reddit's own numbers show how heavy this has become. On its Q3 2026 earnings call, the company said its enforcement team cut the median time to act on violating content from 58 hours to 5 seconds this year (Q3 2026 call transcript, 29 October 2026). The Q2 2026 letter reports 23 million spam views blocked daily (Q2 2026 shareholder letter).
After that, a human reads your profile. In the rules we read, the moderators' test is judgment, not arithmetic. r/startups says its moderators "have the final say" on whether comments are promotional. r/smallbusiness says deliberate abuse of its mention exception "will be recognized and removed." Neither asks for a ratio.
The consequences get worse each time you repeat. The rules we read list removal, a ban, and in r/SaaS URL blacklisting, which makes your domain unusable there even from a new account. Reddit's own page counts getting banned across several same-topic communities as community disruption, and that can draw site-level action. If your posts start vanishing without a removal notice, check whether the account itself has been restricted. Our shadowban guide walks through the checks, and the free account lookup runs the first one.
One more shift to watch. On the Q1 2026 call, Reddit's CEO said the company is working its way out of age and karma limits with better AI-powered spam protection (Q1 2026 call transcript, via The Motley Fool). No date was attached, so the published thresholds above still apply for now.
One soft recommendation: if you would rather not track all this by hand, our thread finder lists live threads where people are discussing your category, and the app drafts replies against each subreddit's rules for you to edit and post yourself, or for us to post on the Done for you plan.

Ways teams game the ratio, and why it fails
Each of these makes sense in the short term and costs you later.
| Tactic | What teams hope for | What tends to happen |
|---|---|---|
| Padding with empty comments ("this," "agreed") to push the ratio up | A 9:1 that looks clean | Filters ignore them and moderators read them as padding. The delete test still fails on every promotional comment |
| Spreading promotion across alt accounts | Staying under each cap | r/SaaS counts secondary accounts toward the limit. r/B2BSaaS bans coordinated promotion. Reddit's rules prohibit using multiple accounts to manipulate votes |
| Having a second account ask "what tool do you use?" so the first can answer | A natural-looking mention | This is astroturfing. We explain why we refuse to do it in astroturfing on Reddit |
| Warming accounts by posting generic karma bait | Instant standing | A history with no subject match reads as a farm. See how to warm up a Reddit account safely |
| Buying aged accounts or upvotes | Skipping the contribution work | Vote manipulation is a site-level violation. What happens is covered in buying Reddit accounts and upvotes |
| Counting replies on your own launch thread as "the 9" | A better ratio on paper | Those replies prop up your own promotion. They are not contributions to the community |
Each one tries to fake the appearance of standing. Moderators judge the real thing, and they can see your history.
What to do in subreddits that ban promotion
Some of the most relevant subreddits for a B2B product don't allow promotion in any proportion. r/sales bans selling and company-branded accounts. r/Entrepreneur says free offers and promotions belong only in the designated weekly threads. r/b2bmarketing asks you to avoid posts promoting your company, agency or service. r/SEO bans self-promotion and branded content. r/ycombinator's rule is a flat "no self promotion."
Your options, roughly in order of how often they work:
- Use the sanctioned thread. r/startups, r/msp, r/devops, r/Entrepreneur and r/smallbusiness all run weekly or stickied threads for exactly this.
- Contribute with no pitch. Your profile still shows up in Google and in AI answers that quote the thread. The value is indirect, which is the point of the 2026 growth report, but it's real.
- Ask the moderators. Some rules include an approval path. r/SaaS requires mod approval through modmail for surveys and polls. r/startups wants two weeks' lead time and approval for an AMA. Ask before you post, not after a removal.
- Let customers speak. r/sales allows recommendations from customers of the product and bans them from anyone who works for it or is connected to it. If you have real customers who are active there, don't script them, and never offer anything in return.
- Buy an ad. r/sysadmin points people to the Reddit advertising system for this, and the r/devops rule says the same thing more bluntly. The tradeoffs are in how much Reddit ads cost and whether they are worth it for B2B.
- Pick a different subreddit. If the audience is the same and the rules are friendlier, go there. Our subreddit finder helps.
If you build tools, check this before you plan a launch post: r/SaaS has a separate rule against promoting SaaS products made for advertising, promotional outreach, lead or opportunity detection, or ad and content generation. That includes tools that draft or automate promotional posts, comments or DMs on Reddit.
A pre-post checklist you can copy
Run this before any comment or post that mentions your product or links your content.
- I read the subreddit's current rules page today, not last month's notes.
- The rules allow this format here (post, comment, flair, weekly thread).
- My ledger shows recent contributions in this subreddit, not only in others.
- Over the last 30 days, my account-wide ledger shows at least 9 contributions per promotion.
- If I delete the product line, the comment still fully answers the question.
- I disclose my relationship in plain words, at the start or the end.
- I am not reusing wording from another subreddit this week.
- No other account of mine has promoted the same thing in this subreddit.
- I did not ask anyone to upvote it, and nothing I wrote asks anyone to DM me.
- Where I wasn't sure it counted, I asked the moderators or skipped it.
Common mistakes and what happens
| Mistake | What usually happens |
|---|---|
| Starting with a promotional post from a brand-new account | Filtered by karma and age gates, or removed on sight. Some subreddits state this plainly as a ban reason |
| Reading 9:1 as permission to promote every tenth action anywhere | Violates caps like r/SaaS's 60-day limit even with a clean ratio |
| Counting only your global ratio | A thin local record gets you removed in the one subreddit that matters |
| Rewording the same pitch across subreddits | Looks like spam and gets you reported across communities, which Reddit's disruption page treats as a pattern |
| Dropping a link with no context | r/SaaS calls "naked" links and product descriptions spam. Many other subreddits say the same in other words |
| Arguing with a removal in public | Moderators have the final say in most rules we read. Ask politely by modmail instead |
What 9:1 is good for
Used properly, the ratio is a discipline. You read before you write, you answer only the questions you know the answer to, and you stop treating every thread as a billboard. It cannot replace the subreddit's own rules or the moderator's read of your account.

FAQ
Is the 9:1 rule an official Reddit rule?
No. It comes from Reddiquette, which calls itself an informal expression of users' values. Reddit's enforceable rules say to participate authentically and not to spam. The numbers moderators enforce are in each subreddit's own rules.
Does the 9:1 rule apply to comments or only to posts?
Reddiquette's wording covers submissions that are your own content. Most subreddit rules cover comments too, including product mentions and links inside replies. r/SaaS, for example, applies its 60-day cap to posts and comments alike.
How many Reddit posts can I make about my product?
It depends on the subreddit. As read on 3 November 2026, r/SaaS allows one mention or three links per 60 days, r/B2BSaaS allows one post per project every 10 days, and r/startups allows promotion only in its stickied thread. Read each subreddit's live rules before you post.
Do I need to disclose that I work for the company?
Yes, and several subreddits require it. r/SaaS wants affiliation stated at the start or end, r/devops wants it at the top of a post or comment, and r/sysadmin says users must disclose any affiliation with a product. Disclosing everywhere is safer than keeping track of which subreddits ask.
What if my 9:1 ratio is fine but my post was removed?
The ratio was never the test. Look in the subreddit's rules for a cap, a weekly thread requirement, a karma or age gate, or a ban on the format you used. If none of those apply, message the moderators politely and ask what you missed.
Can I just use a second account to stay under the limit?
No. Several subreddits count secondary accounts toward the same limit, and Reddit's own help page prohibits using multiple accounts to manipulate votes. It's also the fastest way to turn one removal into bans across several communities.
How long does it take before I can promote anywhere?
There is no universal answer. Plan on weeks of real contribution in each subreddit first. Our guides on warming up an account and promoting without getting banned cover timelines and what moderators told founders.
