These are great tips! I also tried to keep SEO really simple for people in my recent talk: "3 SEO Lessons from 2,000,000 Views on Medium | Dr. Derek Austin 🥳 | Momentum 2021."

I took a bit of a different approach, but I think your 3 tips are spot on: use bullet points, link to facts, and be concise.

Mine are:

1) Use the right keywords

2) Use the right domain

3) Be specific

I illustrate them with examples from my own writing in my talk.
