In this post I’m going to show you the best tools for finding, researching and analyzing subreddits that are a perfect fit for your next post on Reddit.

Unlike our post on analyzing users, we’ve included only tools that are focused entirely on subreddit analysis.

In fact, these are the tools we use internally within our managed Reddit marketing campaigns to do research before we plan campaigns.

What is a subreddit?

Subreddit is a category on Reddit, discussing a specific topic or area and has its own posts associated with it. There are millions of subreddits and they can be upvoted, downvoted and commented on based on their popularity.

When planning this post, we found dozens of subreddit finder tools that could fit the bill for inclusion. But we wanted to focus on only the best and most useful to add to your toolbox.

To be included, a tool had to meet three requirements.

It had to be:

  1. Widely used 
  2. Offers above-board value + actionable data
  3. Free

Without further ado, let’s jump in.

RedditList: best for top 100 subreddits

The RedditList homepage is best known for being one of the first subreddit aggregators out there.

The page contains an ordered list of subreddits, sorted by growth over 24 hours & subscriber count.

Although it doesn’t have so much in the way of insights about the subreddits, it’s still useful for finding top-100 communities you might’ve not thought to post on.

They even have their own subreddit!

Reddit Metrics: best for detailed subreddit statistics

The Reddit Metrics homepage

Like Redditlist, Reddit Metrics has been around for a long time. Unlike RedditList however, it’s easier to browse and dig deeper through individual subreddits.

Their homepage shows an easy-to-use overview of the current state of Reddit. From there you can

  1. See the fastest growing subreddits overall
  2. See the current trending subreddits
  3. See historical information about Subreddit & User growth
  4. Download CSV’s with detailed Subreddit information

Thinking about crossposting your next submission?

Check out SubredditStats before you do.

SubredditStats has a handy search function, which will pull up the most related subreddits to the one you’ve entered.

Here’s what we got when we put in the /r/travel subreddit.
