How do you find subreddits that actually drive traffic?

I usually look at whether people are actually interested in the topic. If I see users asking questions about the same thing I’m working on, I feel that subreddit may be worth trying.
No point posting where nobody cares

I usually spend a few minutes just reading the recent posts before deciding on a subreddit It gives me a better idea of what people are actually talking about there. Sometimes the subreddit looks good at first, but the recent posts tell a different story.

For me, I’d also look at whether people are actually asking questions related to my topic. If I keep finding useful questions there, that subreddit is probably worth keeping an eye on .
