A content management system, or CMS as it's also known, is software that allows you and your team to manage and update digital content for your websites. Content is collected together and stored in the CMS separate to the site. Choose to display your content on the site on pre-designed site layouts or use blank pages to design your own. Use dynamic pages to generate many pages that look the same but have different content—a huge time saver that works well for all sites, including travel and real estate listings.
