Self-promotion rules by subreddit

Every verdict below is classified from the subreddit's own public rules and backed by a quoted excerpt on its page. Last refreshed 2026-06-10. Rules change, so always skim the live rules before posting.

Frequently asked questions

How are these self-promotion policies determined?

We fetch each subreddit's public rules page and classify its stance on self-promotion into three buckets: not allowed, allowed with conditions, or allowed. Every verdict is backed by a quoted excerpt from the actual rule, shown on the subreddit's page, and re-checked roughly monthly.

Why is a subreddit missing from this directory?

We only list communities whose public rules we could fetch and verify. A subreddit may be missing because it is private, because Reddit has banned it, or because it has not been through our review cycle yet. Check the spelling first, then search the directory for a similar community in the same niche.

Can you promote your product in subreddits that ban self-promotion?

Not directly, but a ban does not make the community useless for finding customers. You can still reply helpfully to people who are actively asking for a solution like yours, which is welcome in nearly every subreddit and converts better than promotional posts.

What makes a subreddit worth monitoring?

Visible buying language

The best communities have users asking for tools, comparing alternatives, complaining about workflows, or describing a problem with enough detail to start a useful reply.

Relevant conversations

Large subreddits create volume, but smaller niche communities often produce cleaner intent. The right mix depends on your product category, price point, and buyer persona.

Rules you can respect

Reddit outreach works only when replies fit the community. These guides focus on helpful engagement first, with product mentions only where they answer the original question.
