Questions answered
Subreddit Finder FAQ
The calculator provides an informed estimate. Reddit and individual communities retain the final decision.
Are the suggested subreddit rules checked live?
No. Community rules and activity change, so every suggestion must be verified manually before participating.
Does relevance mean promotion is allowed?
No. A relevant audience may still prohibit self-promotion or links.
Can I enter a product URL?
Yes, but include a plain-language description because this version does not crawl the website.
