Marketers keep posting in r/marketing. That room is full of other marketers. Your customer is in the niche subreddit for their job, their hobby, or their software stack. Start there.
Member counts go stale. Promo rules change. Confirm on the subreddit before you post, and use the finder when you only have a topic, not a name.
Rooms about marketing
Useful for thought leadership and hiring, not for pitching a product to end users.
| Subreddit | Good for | Direct promo |
|---|---|---|
| r/marketing | Industry talk, career, strategy | No |
| r/digital_marketing | Tactics, tools, campaign post-mortems | Rare, usually in threads |
| r/SEO | Honest tool tests, technical questions | No ads. Comparisons with data can live |
| r/PPC | Paid media operators | Vendor talk with disclosure |
| r/content_marketing | Writing and distribution | Limited |
Rooms full of buyers
| Subreddit | Who is there | What lands |
|---|---|---|
| r/entrepreneur | Founders, mixed quality | Personal stories. Pure ads die |
| r/startups | Funding, hiring, product | Growth experiments with numbers |
| r/smallbusiness | Operators with real bills | Practical tool and process answers |
| r/SaaS | SaaS founders | Launches framed as feedback, pricing talk |
| r/EntrepreneurRideAlong | People posting the journey | Transparent progress, not a launch dump |
Where sharing a project is the point
- r/SideProject — showing what you built is the content.
- r/IMadeThis — same idea, including non-software.
- Roast-my-startup style rooms — feedback, not a landing-page drop.
- Weekly megathreads in bigger subs — low glamour, actually allowed.
How to use them without a ban
Read the sidebar. Contribute for real. Keep self-promo rare. For the wider system see Reddit marketing. If you need a post written in that voice, order it. If you only need the room list, the finder is enough.
Questions
What are the best subreddits for marketing a product?
Start with the community your customer already uses, then add one founder room and one place that explicitly allows sharing projects. r/marketing is for marketers talking shop, not for pitching them.
Where is self-promotion allowed on Reddit?
r/SideProject, r/IMadeThis, roast-my-startup style rooms, and weekly megathreads in larger subs. Everywhere else, assume you need a history in the room first.
