- Inconsistent schedule — readers unsubscribe when posts skip.
- Too long-form — most readers prefer 800-1,500 words.
- No call-to-action — every post should ask for replies, shares, or paid upgrades.
- Ignoring Notes — the algorithm rewards Notes activity.
- No cross-promotion — relying solely on Substack discovery.
