How do WordPress SEO guides work?
Each guide answers one question, and the guides are grouped into clusters. Pick the cluster that matches the problem you have. If pages are missing rich results, start with the schema guides. If you want search engines to understand what your site is about, start with semantic SEO and entities. If new pages are not being found, read the internal linking guides. Google’s own SEO starter guide is a good companion for the basics.
