How to rank non-WordPress sites ?


For WordPress sites, there are hundreds of plugins which identify errors and highlight suggestions for SEO like Yoast SEO plugin.

But my question is " what are the best ways to do SEO on a plain HTML site?"

I already have information related to meta tags, connect the site to google console and analytics, images, and content optimization so does anyone experienced provide some good tutorials or suggestions on doing SEO on a non-Wordpress site?
