WordPress is a wonderful open-source CMS with a lot of useful features. But another reason why WordPress is considered awesome is because of the huge set of free plugins and themes offered by developers all around the globe to help anyone get started with their website.

I have worked with hundreds of WordPress-based sites by now and with all my experience, I have found a few plugins to be very useful and can be used in almost any type of WordPress website. Here is the list of plugins that I think are must-have plugins for your WordPress website in 2021.

Rank Math SEO plugin was released towards end of year 2018 and just within two years it has become one of the top SEO plugins for WordPress.
