Yoast SEO is a WordPress plugin that helps you optimize your WordPress SEO. The free WordPress SEO plugin is perhaps the most widely used plugin in the world and has many options. The Premium plugin has a lot of useful extensions over the already very valuable free version.
Joost De Valk built WordPress plugins for himself to improve WordPress and the “Robots meta” plugin, which is still central to the Yoast plugin today, is actually at the foundation of Yoast.
