Common Mistakes
- Spamming everywhere at once - Pick 3-5 channels, do them well
- Pure self-promotion - Add value first, promote second
- Ignoring feedback - Every comment is a gift
- One-and-done - Promotion is ongoing, not a single event
Tracking What Works
Use GitHub traffic analytics:
- Settings - Insights - Traffic
- Check referrers weekly
- Double down on what works
Conclusion
GitHub repo promotion is not about being everywhere. It is about being valuable somewhere. Pick your channels, show up consistently, and let your work speak for itself.
