I have been taking notes myself and combining it with community notes from another course member, resulting in a decently comprehensive note system for semantic seo, though it is not finished yet. You can see it and the internal linking between notes in the graph below.
I also bring some light bedtime reading for you all that I think will help you understand semantic seo a bit more, it certainly helped me.
