Subreddit finder
Search a subreddit to find the ones similar to it, and see how big each is, how busy it is, what its rules say, who posts most, and when its readers are actually online.
How to find similar subreddits
Start with a subreddit you already know your buyers read. The finder lists the communities its moderators link as related, the most reliable signal there is, because the people who run the subreddit picked them. When a sidebar links none, it shows the subreddits that its most active posters also post in.
Click any result to load its size, posts per day, rules and best time to post, plus its own similar subreddits. A few clicks turns one subreddit you know into a shortlist of places to watch.
