How do you post on Reddit without sounding promotional?

The 9:1 rule: for every self-promotional post, you should have nine posts that contribute without a link to your product. Reddit's spam filter and its community are both harsher than any other platform. When you do post about your own work, frame it as a story or a lesson, not an announcement — "What I learned shipping X" beats "Check out my new product." Engage with comments as yourself, not as a marketing account. Subreddits have specific rules — read them, some ban any self-promotion outright. Post where your users actually hang out, not where you wish they did. And never post the same message across multiple subreddits at once; Reddit detects and shadowbans that.
