Memo for SEO optimizers

So I decided to share some material that I myself compiled during an express study of SEO optimization and site promotion. Just caught the video course of Yusuf Gubaidullin, who sells it on promoguide.ru and decided to take the opportunity. Honestly, I did not like the course - it is a tedious story. I rated the content at 4 with a minus, and the presentation - at 2 with a plus. SEO itself is a very boring thing, but necessary, so I made a small memo for myself - not to keep it in my head and it is easy to remember when I need to. There are two files: the first is just a picture, the second is in the freemind format, for those who want to add something for themselves.
