Reddit's old 9:1 guideline is still the clearest way to explain a deeper truth: accounts that only show up to promote lose trust fast. This preview estimates whether an account looks contribution-heavy or promotion-heavy before you post again.

Check whether the account looks like a participant or a promoter.
A Reddit account can survive one promotional post when the surrounding history is useful. It struggles when every visible contribution points back to the same product, domain, newsletter, or founder agenda.

Why Reddit is different
Self-promotion is judged by pattern, not just one post.
Moderators and users look at account history. If the account repeatedly links to the same domain or only comments when there is something to sell, the next post starts with a trust deficit.
The 9:1 rule is a warning
It is not a universal law, but it captures Reddit's expectation that promotion should be surrounded by much more helpful participation.
Domains create fingerprints
Repeated links to the same product, blog, affiliate offer, or landing page are easy for communities to notice.
Comments count too
A helpful comment history can lower risk. Thin comments that only steer users toward your product do the opposite.
Context changes tolerance
Some communities allow transparent founder participation. Others treat any commercial link as promotion and require megathreads.
How it works
From account history to self-promotion risk.
The calculator starts with the username, product term, and visible promotion signals, then frames the result as a conservative account-trust preview instead of a fake certainty score.
Define what counts as promotion
Enter the brand, domain, product, newsletter, or repeated phrase that would make a post self-promotional for this account.
Estimate contribution balance
The preview estimates whether the account reads as mostly helpful participation, mixed contribution, or promotion-heavy.
Plan the next ten actions
If the ratio is risky, the fix is a sequence of useful comments, non-link answers, and community-first posts before another promotional ask.

How to use the Reddit 9:1 rule without treating it like a loophole.
The point of the 9:1 rule is not that ten posts magically make a pitch acceptable. It is that Reddit communities want evidence that an account is there for the community, not only for extraction. The ratio is useful because it turns trust into something a marketer can audit before posting.
Decide what promotion means for the account.
Promotion includes more than direct product links. It can include newsletter links, founder updates, affiliate URLs, repeated mentions of the same brand, comments that push users into a funnel, or helpful-looking posts that exist mainly to create a call to action. Be strict when defining the promotional side of the ratio. Communities usually are.
Look at visible history from a moderator's point of view.
A moderator will not read your marketing plan. They will scan the profile. If recent posts and comments repeatedly point to the same product, the account looks promotional even when each individual post has a plausible explanation. Count recent visible contributions, separate genuine help from brand-driven comments, and pay attention to the last few weeks more than ancient history.
Fix ratio risk with useful participation, not filler.
Do not spam low-effort comments just to improve the count. That creates a different trust problem. Repair the ratio by answering questions in your expertise area, sharing non-promotional examples, asking thoughtful follow-ups, and helping without links. The goal is for a future promotional mention to sit inside an account history that already earned the right to be heard.
Make commercial intent transparent and secondary.
When you do promote, be clear about your relationship to the product and make the useful part of the post stand on its own. A transparent founder note with a real lesson, data point, or community-specific question is safer than a disguised ad. The ratio creates permission to contribute, not permission to trick users.

What is Reddit's 9:1 self-promotion rule?
The 9:1 rule is an old guideline that says roughly nine contributions should not be self-promotional for every one that is. It is not enforced uniformly, but it remains a useful way to think about Reddit account trust.
What counts as self-promotion on Reddit?
Direct product links, repeated brand mentions, affiliate URLs, newsletter links, founder launch posts, comments that push users toward your offer, and disguised promotional content can all count as self-promotion.
Can I post about my own product on Reddit?
Sometimes, but it depends on the subreddit, your account history, transparency, and whether the post is genuinely useful without the promotional ask. Many communities require promotion to happen only in specific threads.
How do I lower my self-promotion ratio?
Add genuine helpful participation: answer questions, share examples without links, ask useful follow-ups, and contribute in communities where you understand the norms. Avoid low-effort filler comments.
Is this calculator free?
Yes. The preview is free and does not require a Reddit login. Deeper account workflows are available inside RedditMaster.
