Reddit Launch Post

What is a Reddit launch post?

A Reddit launch post is a post in one or more subreddits where you tell the story of a product you built and invite people to try it. Subreddits are topic communities with their own volunteer moderators and their own rules, so the same post can be welcome in one and removed in seconds from another.

Reddit users dislike ads and love honest stories. A post that reads like a press release gets downvoted, and a post that explains a real problem, what you tried and what you made next can bring hundreds of interested visitors and a thread full of blunt, useful comments. The whole method comes down to that difference.

When should you use it?

• Good fit: consumer apps, side projects, tools for hobbies (gardening, knitting, running, gaming), small SaaS products, templates and anything with a clear community of fans on Reddit.
• B2B works in professional subreddits (accounting, nursing, teaching, small business), but only where the rules allow sharing your own work and only with a story your peers will recognise.
• Skip it if you have never used Reddit and don’t have 2 weeks to take part first, or if your only subreddits ban self-promotion outright.

How do you do it, step by step?

1. Make a list of 5 to 10 candidate subreddits. Split them into two groups. Group A: communities made for sharing projects, like r/SideProject or r/alphaandbetausers. Group B: communities where your customers hang out, like r/nursing or r/smallbusiness. Group B brings buyers; group A brings other makers and early testers.

2. Read every rule page and the pinned posts. On each subreddit, open the “About” tab and the rules, then read the top posts of the past month. Note in a sheet: is self-promotion allowed, only in a weekly thread, or banned? Are links allowed in the post body? Is there a minimum account age or karma (points from upvotes) to post? When the rules are unclear, send the moderators a short message: “I built a free planner for allotment gardeners. Would a post about how I built it be OK here, or is there a thread for that?”

3. Take part before you post. Spend 10 to 15 minutes a day for 2 weeks answering questions in your group B subreddits. Our rule of thumb is the old 9:1 balance from Reddit’s early self-promotion guidance: about 9 helpful comments or posts for every 1 about your own thing. Moderators look at your profile, and an account that only posts its own links reads as spam.

4. Write the post story-first. Structure: the problem in one paragraph (yours or the one you saw), what you tried that didn’t work, what you built, what it does today, what’s free, and one honest question. Title it like a person: “I teach maths and got tired of rewriting the same 30 homework sheets every term, so I built a tiny generator for it”. Avoid “Introducing”, taglines and capital letters for emphasis in the title.

5. Put the link where the rules allow. Some subreddits want it in the post, some in a comment, some only on request. Add a UTM tag (a label at the end of the link, like ?utm_source=reddit&utm_medium=post&utm_campaign=sideproject) so you can see which subreddit sent people.

6. Post in one subreddit at a time. Pick the best fit, post when you have the next 6 hours free and answer every comment. Wait 2 or 3 days before posting in the next one, and rewrite the post for that audience. Posting the same text in 8 subreddits within an hour is the fastest way to get your account flagged as spam.

7. Reply like a member. Answer criticism with specifics, thank people for bug reports, and ask follow-up questions: “When you say it’s confusing, is it the first screen or the swap request?” Never use a second account to praise your post or ask friends to upvote it. Reddit treats vote manipulation as a sitewide rule break.

What does a worked example look like?

Say Lea runs a small app that helps allotment gardeners plan which vegetables to sow each week, based on their region. She has 40 users from her own allotment association.

She lists r/SideProject in group A, plus three gardening subreddits in group B. Two gardening subreddits ban self-promotion. The third allows “made it myself” posts on Saturdays only. For 2 weeks she answers sowing questions with photos from her own plot, which earns her a few hundred karma and some friendly replies.

Her Saturday post: “I kept forgetting to sow my second batch of carrots, so I built a free planner that tells you what to sow this week in your region”. She writes about the notebook she used before, shares a screenshot and asks which vegetables are missing. The post gets 180 comments. People ask for a frost-date warning and a version for balcony growers. 260 people sign up that weekend, and 31 send her a message with suggestions. A week later she posts in r/SideProject about how she built it, which brings 70 more sign-ups and two offers to help with the Android version.

What mistakes should you avoid?

• Skipping the rules page. Most removed launch posts broke a rule written in plain sight.
• Posting from a brand account. People talk to people. Use your personal account and say clearly that you made the thing.
• A sales pitch in story clothing. If every paragraph ends with a benefit, readers notice. Include what went wrong and what you still don’t know.
• Cross-posting the same text everywhere. Each subreddit has its own tone, and identical posts across many communities look like spam to moderators.
• Arguing with critics. You can disagree once, politely, with a reason. Then move on.

How do you know it worked?

Look at three numbers per post: upvote ratio (Reddit shows it on your post; above about 80% means people welcomed it), number of comments from potential users, and sign-ups from that subreddit in your analytics. Our rule of thumb: a post in a customer subreddit that brings 20 or more sign-ups and at least 5 people asking questions about their own situation is a win.

Go: your group B post was welcomed and brought sign-ups from the people you want. No-go: the post was removed or got a low ratio in every customer subreddit. Then go back to Reddit community participation for a month before trying again.

What should you do next?

Message the people who left the most detailed comments and ask for a 15-minute call; they become your first test group. Turn the most-asked question into an article with a problem-focused blog post. If your product is technical, take the same honest tone to a Show HN post.

FAQ

Which subreddits allow self-promotion?

Communities built for sharing projects, like r/SideProject, welcome posts about what you made, and many niche subreddits have a weekly thread for it. Rules change, so read each subreddit’s rules page before posting.

Is the 9:1 rule an official Reddit rule?

Not today. It comes from Reddit’s older self-promotion guidance, and some subreddits still quote a similar ratio. Treat it as a safe habit, and always follow the specific subreddit’s rules first.

Should I put the link in the post or in a comment?

Follow the subreddit’s rules. If both are allowed, a link at the end of a story post works well, and some founders add it in the first comment so the post itself reads as a story.
