Before you post
Read each subreddit's rules, wiki, and top posts from the last 30 days. Lurk for two weeks minimum. Promotion tolerance varies wildly—even between similar communities.
How to Choose Subreddits for Your Brand
- Match intent: Are members asking buying questions or sharing memes?
- Check activity: Prefer communities with daily posts and comment threads
- Audit rules: Some ban all self-promotion; others have weekly showcase threads
- Test with comments first: Build karma before original posts
Subreddits to Approach With Caution
- Default front-page subs (r/AskReddit, r/funny) — wrong audience for B2B
- Heavily moderated anti-promo communities without clear value rules
- Subreddits where your competitors already dominate the narrative
