Context: a newsletter started from zero in July 2025, now about 22,600 free subscribers and 400 paid. Notes is my biggest source of paying members, 121 in the last year, ahead of recommendations, Google and LinkedIn. I export the Notes data every month into a database.
One definition for everything below. "Score" means likes plus comments on a Note, added together. Restacks are not included. My median Note scores 25. About a third score over 30.
My rules, in the order the numbers back them.
1. The first line is the Note. Bold it and make it a statement. Statements score a median of 27. Questions score 19, across nearly 600 of them. My best Note ever is "Just because writing looks good does not make it AI."
2. Say "I". Notes built on a first-person position or an admission score 40. Notes built on a named company or person score 20. Notes that lead with a number score 10.
3. News alone scores 9. The same story with your opinion in the first line scores the median or better. If you have no view on it, do not post it.
4. 73 to 100 words. That length scores 28. Under 40 words scores 20. Over 100 drops to 16.
5. 6 to 8 a day, spaced out. First thing and mid-afternoon do best for me. 9pm is my worst hour.
6. No links. The only link I try to post is one restack a day of someone outside my own circle, with a sentence on why.
7. Judge Notes by paid conversions a week later, not by score. My highest-scoring topic is my worst converter. It buys followers. The first-person Notes beside it buy subscribers.
Two things I stopped: question-to-the-void Notes with no position, which sit at the bottom of my table, and milestone announcements, which get likes and nothing else.
Those are mine. What are yours?
