I've been doing the same for over 20 years now, I had an ezine before blogs were a thing. I always found this approach of headlines for the algorithm silly.

The recipe for me is - deliver huge value, if people don't know about it, their loss. If someone finds it valuable, the cheapest way to deliver some value to their friends is to share it with them.

I don't have many listeners or readers, certainly don't write bestsellers, but the satisfaction from the relationship with my audience is something I would never swap for a bunch of normies wanting to know what pumps next week.
