Honestly documenting the journey is probably the best thing you can do right now. Reddit users can tell immediately when someone’s trying to “market” versus genuinely sharing progress.
If I were you, I’d just post the real stuff like traffic changes, rankings moving, mistakes, experiments that failed, random wins, etc. Those posts usually do way better than polished advice threads anyway.
Also don’t stress too much about being new here. Reddit growth is weirdly momentum based. One genuinely useful post can suddenly make people start recognizing your username everywhere.
What kind of site/project are you working on btw? Curious what niche you landed your first client in.
