The WordPress CMS allows for web-based publishing of content, version control (so that you can revert to previous versions of content) plus different levels of user controls and permissions. Updating the website is made easy – For example, components such as the header, footer, menus and sidebars can be updated in one place so you do not need to replicate the changes per page.
