It is difficult to provide an exact number as the usage of content management systems (CMS) is constantly changing and new websites are created regularly. However, statistics from BuiltWith, a technology tracking and market intelligence company, estimate that as of October 2021, around 64.3% of all websites that use a CMS are built on WordPress, making it the most popular CMS by a significant margin. Other popular CMS platforms include Joomla with 3.3% market share, Drupal with 2.8%, Shopify with 2.1%, and Squarespace with 1.5%. These statistics suggest that a significant portion of websites, especially smaller ones, utilize a content management system for their management and operations.
