The Reddit 9:1 self-promotion rule: how to track your ratio
Reddit retired the 9:1 rule years ago but subreddits still enforce it through AutoMod. Here is the audit method that tells you where you actually stand.
Reddit officially deprecated the 9 self-promotion rule in September 2016 and rewrote its spam guidance to focus on intent rather than ratios. That is the version Reddit's policy team will quote you. It is also irrelevant. Almost every subreddit that allows promotion at all still enforces a 9 ratio (or stricter) through AutoMod, mod culture, and the reading habits of long-time community members. Here is how to audit yours before the next sub does it for you.
Was the Reddit 9 self-promotion rule ever actually a rule?
It was a guideline, not a sitewide rule, and Reddit removed it on September 7, 2016. The original wiki at /wiki/selfpromotion (still readable in the Internet Archive) recommended that for every one self-promotional submission you made, you participate in nine other Reddit conversations. The 2016 r/modnews announcement replaced the numeric ratio with an intent-based policy: "it's not what you post, it's how you participate."
Reddit's current Content Policy and the spam help article carry that intent framing forward and never mention 9. That is the version Reddit admins will quote in any appeal. It is also the version that does not match what subreddit moderators run AutoMod against, which is the version that determines whether your next post survives.
Why do subreddits still enforce 9 in 2026?
Because mods learned the old rule and built their AutoMod stacks around it before Reddit retired it. The ratio became cultural rather than statutory. Signals runs an aged Reddit account marketplace plus an editorial network for AI brand mentions across Reddit, Quora, Product Hunt, and Threads, and across the promotional-friendly subs we monitor (r/Entrepreneur, r/SEO, r/startups, r/marketing, the larger SaaS-adjacent communities), the AutoMod YAML still checks for domain repetition, self-link frequency, and submission history before a post ever reaches the front page.
The r/Entrepreneur rules wiki keeps an explicit "10 percent rule" framing. r/SEO's rules call out that "self-promotion must be minimal compared to your other contributions." Other subs encode the same idea inside AutoMod through author.submission_count, per-domain limits, and "approved submitter" gates. Reddit's AutoMod reference covers the YAML primitives mods use to enforce it without ever publishing a number in the sidebar.
How do you measure your own ratio in 10 minutes?
Open two URLs while logged in: https://www.reddit.com/user/\<your-name>/submitted/?sort=new and https://www.reddit.com/user/\<your-name>/comments/?sort=new. Filter to the last 90 days. Count two columns: total items, and items that link to, mention, or recommend a domain or product affiliated with you. Divide. That is your true ratio.
The trap most operators fall into is counting only link posts. AutoMod tracks comment behavior too. A comment that drops your URL counts as self-promotion. A comment that names your product without a link still counts at most subs. So does a thread reply that recommends your tool by name to a question-asker. If you include comments in the count and you are above 15 percent over 90 days, expect filtering inside subs that take the 9 framing seriously. The complementary view (how Reddit aggregates your overall behavior into Contributor Quality Score) is the second number worth tracking; CQS and the per-sub ratio move together.
What ratio do specific subreddits actually target?
The official guidance is dead, but the operating thresholds clustered around it. The table below reflects what we observe holding up across recent campaign posts in the major promotional-adjacent subs; it is operator pattern, not Reddit policy.
| Subreddit | Effective ratio cap | Enforcement |
|---|---|---|
| r/Entrepreneur | 1 (10 percent) | Explicit rule, mod-enforced |
| r/SEO | 1 (10 percent) | Explicit rule, mod-enforced |
| r/startups | 1 (about 7 percent) | AutoMod plus mod review |
| r/marketing | 1 (10 percent) | AutoMod plus mod review |
| r/SaaS | 1 (5 percent) outside weekly threads | Strict AutoMod; weekly self-promo thread is the safe valve |
| r/smallbusiness | 1 (10 percent) | Mod-enforced; flair required |
| Niche hobby subs | 1 or stricter | Culture-enforced; no formal rule |
The single safest framing: target 5 percent self-promotion across your trailing 90 days of all submissions and comments combined. That clears every major sub's threshold and leaves headroom for a launch week. The exception is subs that publish a weekly self-promotion megathread (r/SaaS, r/Entrepreneur, r/SideProject); posts inside the megathread do not count against the ratio.
Which tools actually automate the audit?
Three free options cover most of the work. The Reddit JSON endpoint at https://www.reddit.com/user/\<name>/submitted.json?limit=100&t=year returns up to a year of submissions in a parseable format; a 30-line Python script can categorize them by domain and produce a ratio. SocialGrep indexes Reddit posts and comments and lets you query by author and domain together, which is the fastest way to find every comment where you dropped a specific URL. Reveddit does not measure ratio directly but surfaces every post and comment of yours that mods removed; a high removal rate at a single sub is a leading indicator that your ratio there is already over the line.
For agencies or operators managing multiple personas, the cleanest workflow is to log every brand-adjacent submission and comment into a spreadsheet at the moment of posting (account, sub, type, brand-relevant yes/no) and audit monthly. The audit takes 10 minutes when you maintain the log; it takes two hours when you reconstruct it from Reddit's UI under deadline. The recovery side, once a ratio audit reveals a problem, lives in the shadowban recovery day-by-day playbook because mod-side filtering and sitewide filtering are upstream of the same fix list.
What to do when your ratio is over
Stop posting any self-promotional content for 14 days. Resist the temptation to "balance" by spamming non-promotional posts; AutoMod reads burst contribution as inauthentic.
Make 20 to 30 substantive comments across subs you actually read. Answer questions, share specific experiences, post no links. The goal is a real participation history, not karma farming.
Re-run the 90-day audit. If you are under 10 percent across both submissions and comments, resume promotional posting one item per week per sub, starting in your highest-trust sub first.
Use the per-sub weekly megathreads (where available) for any post that is directly promotional. Reserve your standalone submissions for content that would be on-topic even if you had no brand attached.
If a specific sub has already filtered you and your CQS in that sub is low, no ratio fix recovers you fast; that is when an aged secondary account becomes the operating reality, and the account-mix decision tree (covered in the pillar's account hygiene section) is the next read.
Frequently asked questions
Is the 9:1 rule still in Reddit's sitewide policy?
No. Reddit removed it from the self-promotion wiki on September 7, 2016 and replaced it with intent-based spam guidance. The current Content Policy and spam help article do not mention any ratio. Individual subreddits enforce their own version through rules and AutoMod.
Do comments count toward my self-promotion ratio?
Yes, at every sub that takes the framing seriously. A comment that names or links to your brand counts the same as a self-promotional submission. Many AutoMod stacks specifically track comment-level domain repetition because that is where most modern self-promotion happens.
What ratio is safe across most promotional subs?
Target 5 percent self-promotion across your trailing 90 days combined (submissions plus comments). That clears the 10 percent cap most subs enforce and leaves room for a launch-week spike. Posts inside weekly self-promotion megathreads are usually exempt.
How do I count my ratio without buying a tool?
Pull the JSON feed at https://www.reddit.com/user/\<name>/submitted.json?limit=100&t=year and https://www.reddit.com/user/\<name>/comments.json?limit=100&t=year, dump to a spreadsheet, and tag every row "brand-relevant yes or no." Total brand-relevant divided by total items equals your ratio. Ten minutes if you do it the same day.
What happens if I cross 10 percent in a strict sub?
The first signal is silent AutoMod filtering of new submissions; you will see them appear normal to you but missing from logged-out /new. The second is removals with a generic "low contribution" reason in modmail. Third is being banned from posting, with appeals routed back to the mods who applied the filter. Reset the ratio before the second stage, not after the third.
