As of 2021, WordPress is estimated to power approximately 42% of all websites on the internet. This includes both self-hosted WordPress sites (websites that use the open-source WordPress software installed on a web server) and websites hosted on WordPress.com (a commercial platform that provides hosting and other services for WordPress sites).

This makes WordPress the most popular content management system (CMS) in the world, with a significant lead over other popular CMSs like Joomla and Drupal. WordPress’s popularity can be attributed to its ease of use, flexibility, and robust ecosystem of themes and plugins that can be used to customize and extend the platform’s functionality.

WordPress is used by a wide range of websites, including blogs, news sites, e-commerce stores, corporate websites, and more. It is particularly popular among small and medium-sized businesses that need an easy-to-use and affordable platform for creating and managing their online presence.

Overall, WordPress’s popularity and versatility have made it a go-to choice for many website owners and developers around the world.
