The primary purpose of a content management system (CMS) is to facilitate the creation, management, and distribution of digital content. A CMS allows users to easily publish and edit content without needing extensive technical knowledge or coding skills. It typically features tools for organizing, categorizing, and optimizing content for better search engine visibility. Examples of popular CMS platforms include WordPress, Joomla, and Drupal. By streamlining content management, a CMS supports effective communication and enhances user engagement on websites.
