Question

Search Engine Optimization

Guys, I know that the question looks childish but, I reviewed a bunch of videos about the semantic core, about the selection of keywords and so on. But how to create (or name) categories, pages and records of sensible information is almost non-existent. I work on WordPress. Give hints where to read or look for information on this issue. Thank you.
