Any Tips for Growing a Niche Subreddit?

Hey, I started a subreddit around fitness tips for beginners, but it’s been tough to get people to join and actually engage. I’ve posted some content, tried cross-posting in similar subs, and even ran a few ads, but nothing seems to really work. Feels like I’m missing something. Anyone here have experience with growing a small subreddit? Would love to hear what’s worked for you.

You need to find a USP for your sub. There are plenty of fitness-related communities that are already big. So, give people a reason to join your sub. Reddit's discovery system can work wonders if your sub has potential.

drive traffic to your sub by:
- repost the posts from your sub in other big related subs

- link your posts in other related comments of other subs like "this post here covers that topic really well"

- obvious but SEO ranking your posts to get traffic to them
