01What it is and who is there

Reddit is organized into topic communities called subreddits. Each has its own members, moderators and rules. For a solo builder, the useful ones are subreddits where your users already complain about the problem you solve. Reddit's own help center describes a self-promotion policy that applies across the site, and each subreddit adds its own rules on top. Expect strict moderation: a link post that reads like an advertisement is often removed.

02Cost and what you actually pay for

Posting and commenting are free. You can also buy Reddit Ads, which are a separate channel with their own pricing, covered in another entry. The real cost is time, because the approach that works is to be useful in a community for weeks before you mention your product. Check each subreddit's current rules before you post.

03Is it right for you?

It fits products that solve a problem people already talk about in a specific subreddit, such as a niche tool for a hobby, a trade or a developer workflow. It fits poorly for products nobody discusses, for anyone who wants a quick launch-day spike, and for founders who will only post links. If you cannot name the subreddit where your user asks for help, this channel is probably not for you yet.

04Before you start

  • Make a real account. Use it for at least two weeks before you mention your product. Comment on threads and answer questions.
  • Find two or three subreddits where your users ask for help. Read the sidebar rules and the pinned posts for each one. Many subreddits set a self-promotion limit or ban it outright.
  • Look for a weekly "promotion" or "share your project" thread that some subreddits run. Use those when they exist.
  • Read the site-wide content policy and the self-promotion guidance on Reddit's help center. The help center page could not be checked by the maker of this guide, so read it directly.
  • Decide whether you are posting as yourself. Disclose that you made the product whenever you mention it.

05Step-by-step: how to distribute here

  1. Read the rules of one subreddit fully, including the sidebar and any wiki pages. Note any self-promotion limit or required flair.
  2. Spend two to three weeks answering questions there. Be specific and helpful. Do not mention your product in these answers unless it directly solves the question.
  3. When your product fits a real question, reply to that thread with a short, honest answer. Mention the product only if it answers the question, and say you made it.
  4. If the subreddit has a promotion thread or allows a post, use the format it requires. Include the context, not only the link.
  5. Stay in the thread to answer follow-up questions for at least a day.
  6. Do not repost the same link to other subreddits in one day. Cross-posting the same ad to many communities is a common reason for removal.
  7. Track which threads sent visitors and what those visitors did.

Timing: no source confirms a "best day" for subreddit posts. Check when your users are active in the subreddit's own feed, and post at a time when you can answer comments.

06What to post or submit

Reply template (use this when a question matches your product):

[Direct answer to the question in one or two sentences.]

I ran into the same thing when [your specific experience]. What worked for me was [the step]. [Optional: the tool I built for this, if relevant.]

Disclosure: I built [product] for this, so take that into account. [Link, only if the subreddit allows links in replies.]

Promotion post template (only where the subreddit allows it):

Title: [Plain description of the problem you solve]

Body: I'm [your role] and I built [product] because [specific reason]. Here is what it does: [two sentences]. Free to try: [yes/no and what limit]. I'd like feedback on [one specific question]. Happy to answer questions about how it works.

Link: [your product]

Replace every bracketed part. Do not use "the best," "game-changing" or other hype words.

07Common mistakes and do-nots

  • Do not post the same link across many subreddits. Each one counts as a separate promotion, and the pattern is what moderators look for.
  • Do not use multiple accounts, and do not ask friends to upvote or comment on your post. Vote manipulation breaks Reddit's rules.
  • Do not post in a subreddit that bans self-promotion. Read the rules first. A removed post can get your account restricted.
  • Do not hide that you made the product. Undisclosed affiliation is a common reason for bans.
  • Do not buy upvotes or comments. That breaks Reddit's policies.
  • Do not argue with moderators publicly. Message them if you think a removal was a mistake.

08How to measure it

  • Track visits from reddit.com in your analytics, with a note for each subreddit you posted in.
  • Track the number of replies you received that asked a real question. Those show interest.
  • Watch for removals. A removed post tells you the subreddit's rules are stricter than you read.
  • A realistic test: give each subreddit three to four weeks of helpful answers before judging it. One post is a weak signal.

09Time budget

  • Before: 3 to 5 hours to choose two or three subreddits and read their rules.
  • Ongoing: about 3 to 5 hours a week of useful answers over several weeks.
  • During a post: 1 hour on the day to answer comments.

11Subreddits we cover, and how to stay safe

> Reddit could not be read from the build environment, and search results on each subreddit's rules disagree. Nothing below is a rule of a subreddit. Read the sidebar, the rules page and the pinned posts on each subreddit before you post, because moderators change them.

The subreddits

r/SideProject (guide). Showing projects you built and asking for feedback. Mostly makers and developers. Fits: Early versions, side projects and first launches that want honest feedback. Poor fit: Mature products that need paying customers. Promotion: Described by several guides as one of the most promotion-friendly subreddits. Those are secondary sources, so confirm on the sidebar. To check on the sidebar: Self-promotion wording, any required post format, and any promotion thread.

r/SaaS (guide). SaaS founders sharing tactics, pricing, numbers and lessons. Fits: B2B SaaS founders who can share a specific lesson with real numbers. Poor fit: Consumer apps, and anyone who only wants to drop a link. Promotion: Sources disagree. Several say promotion is limited to a designated thread. The threads named differ between sources (Show and Tell Saturday, SaaS Feedback Saturday). To check on the sidebar: Which thread, if any, allows product posts, and its day. Do not post product links outside it.

r/indiehackers (guide). Bootstrapped builders sharing progress, lessons and questions. Fits: Founders sharing lessons, milestones and products built for founders. Poor fit: Consumer apps and enterprise tools. Promotion: Guides say journey-style posts are welcome and ad copy dressed as a journey is removed. Secondary sources only. To check on the sidebar: The current self-promotion rule and whether a promotion thread exists.

r/startups (guide). Founders asking for advice on ideas, fundraising, hiring and growth. Fits: Feedback on a decision: a pricing question, a launch plan. Poor fit: Product links and direct customer hunting. Promotion: Described as strict about promotion, limited to the threads it allows. To check on the sidebar: Which threads allow product mentions.

Launch safely

  • Read the sidebar, the rules page and the pinned posts for each subreddit before your first post.
  • Use a real account. Comment and answer questions for a couple of weeks before you mention your product.
  • Post once, in the format the subreddit asks for. Do not cross-post the same link to several subreddits on the same day.
  • Say you built the product, every time you mention it.
  • Do not ask for upvotes, and do not ask friends to vote or comment for you.
  • Do not use a second account to comment on your own post.
  • Do not message people you do not know about your product.
  • Answer every comment, especially the critical ones, within the first day.
  • If a moderator removes a post, read the reason and ask the moderators before you post again.
  • Track visits with a UTM link and count the useful replies, not only the upvotes.

How not to get banned

  • A removed post is a warning sign, not a bad day. Stop, read the rule that applies, and change the next post to fit it.
  • The usual causes are: posting a link with no context, a post that reads like an ad, repeating the same post, and more than one post in a short time.
  • Subreddit bans are usually permanent, so ask the moderators before you post if you are unsure.
  • Reddit-wide guidance used to suggest one self-promotional post for every ten regular posts. Several sources say that guidance is no longer official. Treat it as a rule of thumb, and let each subreddit's own rules decide.
