A content management system (CMS) simplifies web publishing by enabling users to create, edit, and manage website content without needing extensive technical knowledge. It provides a user-friendly interface with templates and drag-and-drop features, allowing non-technical users to publish content easily. Additionally, a CMS streamlines collaboration among team members, facilitates updates, and ensures that content can be optimized for SEO. Many CMS platforms also offer plugins for added functionality, making it easier for organizations to maintain a professional web presence without constant reliance on developers.
