What is a subreddit stats checker?
A subreddit stats checker shows how big a community is, how busy it is and how old it is, with the date the numbers were read. This one adds what most stats pages skip: the karma and account age a new poster needs, read from the subreddit's own rules, and the community's stance on self-promotion and links when Rankhog has a guide for it.
How many members a subreddit has
Type the subreddit into the box above, as a name, r/name or a link. The checker shows the member count with the date it was read. Reddit's own sidebar shows a member count too, but it rounds big numbers and does not say how a community has changed. Here you get the exact count, its age and its average growth.
How to see subreddit growth over time
Reddit does not publish member history, so every growth chart you find is somebody's own record. Rankhog keeps one for the subreddits it tracks: a row a day, built from real reads. Once two reads are a week apart, the checker shows how many members the community gained or lost between them. Before that, it shows a lifetime average instead.
Members, weekly visitors and online now
Members are everyone who ever joined, including people who left Reddit years ago. Weekly visitors are the people who actually opened the community in the past week. When Reddit shares both, the second number tells you more about who will see your post. Reddit does not always share an online count with signed-out readers, so the checker never invents one.
How active a subreddit is
Size and activity are different things. A huge subreddit can be quiet, and a small one can answer every question within an hour. Weekly visitors are the best public sign of activity. Pair them with a read of the newest posts: if questions like yours get real answers, the room is alive.
Karma and account age to post
Many subreddits refuse posts from new accounts. Some write the rule down, such as an account at least 30 days old with 100 karma. The checker pulls those numbers from the published rules and shows them next to the stats, so you know before posting whether your account clears them. Run the account analyzer to check your own account against them.
Stats vs rules
Big numbers do not make a room safe for a product mention. Rankhog's guides record each community's stance on self-promotion and links, read from its rules. When a subreddit bans promotion, the stats are still useful for research, but your post there should only ever help, without a link.
Which subreddit to pick
Pick the room where your buyer's problem gets asked, not the biggest one. A subreddit of 20,000 people who all run the kind of business you serve beats two million who scroll past. Check a few candidates here, compare weekly visitors and posting rules, then read their newest posts before you write anything.
