How to promote your startup on r/SideProject

What is r/SideProject?

r/SideProject (reddit.com) is a reddit: built for showing off side projects - one of the most promotion-friendly subreddits for new launches.

Subreddits are where founders find their first users. Reddit links are nofollow, but threads rank in Google for years and are one of the sources AI assistants cite most. Every subreddit has its own self-promotion rules - read the sidebar first, lead with a story or a genuine question, and never post the same link across many subs at once.

How to submit to r/SideProject

1. 1Use an account with real history - new accounts and low karma are often auto-filtered.
2. 2Read the subreddit rules and sidebar: many only allow promotion in weekly threads or on specific days.
3. 3Write a post that is useful on its own - what you built, why, what you learned, and real numbers.
4. 4Put the link in the post body or a comment only where the rules allow it, and add UTM parameters.
5. 5Reply to every comment in the first few hours; engagement decides whether the post reaches the front of the sub.
