So im just starting to learn WordPress and have basic react and mysql knowledge but i dont understand how the seo plugins function. I understand the overview they increase seo by helping you discover keywords people search for but what specifically do they do? Are the just adding meta data and to your html head Ie title and meta description? Surely there is much more involved? And how is mysql content such as blog content, or store collections made available to web crawlers if it is all generated dynamically?

No they don’t.

This is their main function. They add the relevant metadata that search engines are looking for when they are trying to classify your post/site content. Plus, they have other ancillary functions such as warning you when you are missing key pieces of data, or guide you on the formatting of your content that they think will give a slight boost with ranking well.

Yes. It is use to populate the HTML markup of your websites and its pages.
