45 Best Subreddits For Marketing & SEO Professionals

Over the last few years, Reddit has risen in influence to be a social channel that Google elevated in it’s search engine results for it’s user-generated content and also a source of valuable reviews for users.

Reddit is constructed as a network of smaller communities, known as Subreddits. The value of these Subreddits is in their independence and their self-moderation to avoid spamming. Redditors are notoriously anti-spam or self-promotion, making a space where trusted advice and reviews can be found (although the platform has its flaws).

If marketers approach Reddit in the right way, they can see strong brand awareness from an audience of 110.4 million daily active users participating in over 100,000 subreddits.

However, this article isn’t about marketing on Reddit, but a list to find all the Subreddits relevant to marketing and SEO.

Note: Reddit’s new update hides member count in the new UI, but you can still preview the member count upon entering the subreddit’s name in the search bar on mobile.

How To Join And Participate In Subreddits

Once you have a Reddit account, you can join and participate in subreddits. There are a few things to keep in mind before you get started.

  • Complete your Reddit profile. You should add links to your other profiles, including Instagram, Twitter, TikTok, Twitch, Facebook, YouTube, Tumblr, Spotify, SoundCloud, Linktree, Patreon, Cameo, Substack, Kickstarter, etc.
  • Reddit has a karma system, where you receive points when people vote on your comments and posts. Some subreddits require members to have a minimum number of karma points before posting.
  • Every subreddit is moderated by Redditors and has its own set of rules. You’ll find these rules in the subreddit’s sidebar or the pinned post on the group – or both.
  • When posting to subreddits, note that some will allow you to post text, links, videos, and photos. Others may limit you to text-only.
  • Some subreddits have separate chat groups on platforms like Discord, Telegram, or WhatsApp – the ones that do typically have them listed in the sidebar.
  • You can find related subreddits in the sidebar if you like a particular subreddit.

When evaluating a subreddit to join, look for an active community and posts that receive responses from other Redditors.

And unless your goal is to spam a subreddit (which it shouldn’t be), you want to see that the moderators of the subreddit keep it spam-free.

Conclusion

No matter what you want to learn or discuss, you can find a subreddit to match your interests.
