On Reddit, the useful comment is the marketing. This skill reads a community's rules, drafts a genuinely helpful public reply from your real experience, keeps your product out of it, and tells you when a private message would be welcome.

On Reddit, the useful comment is the marketing.
Reddit is one of the best places to find people describing their problems in detail. It's also one of the fastest places to get banned for selling to them. Moderators remove promotion, people downvote anything that smells like an ad, and an unexpected private message usually gets ignored or reported. It's still easier to stand out on Reddit than on X or LinkedIn, but only once you've learned how each community talks.
What you need
- What you sell, and who it's for.
- The post you want to respond to, and the subreddit it's in.
- Your real experience with the problem. This skill never makes experience up.
Steps
Learn the room. Read the subreddit's rules and a week of its top posts before you comment. Notice the tone, what gets upvoted and what gets removed.
Answer the question they asked. Write the reply you'd want if you'd posted it: specific, honest, drawn from what you've actually done. It should help everyone reading the thread, not just the person who posted.
Leave your product out. Your profile can say what you build. People who find your answer useful will look.
Keep showing up. One good comment is luck. A month of good comments in the same community makes you someone people recognise.
Message privately only when invited. If someone replies asking for more, or the post asks people to get in touch, a short private message is fine. Keep helping first. Mention what you build only if it's directly relevant, once.
Output
Community rules on promotion: <summary>
Reply:
<text>
Message privately? <yes, because... / no, because...>
Good and bad
Good: "had this with my last app. what changed things was answering questions in the two subreddits where people complained about the exact problem, for a couple of weeks, before mentioning the app once. happy to share what I searched for if it helps."
Bad: "We built a tool that solves this! DM me."
Rules
- Never open with a private message.
- Never invent experience, pretend to be a customer, or upvote yourself from other accounts.
- If a moderator or the person says no, stop.
- Treat every community as its own place with its own rules.
