When your website was spun up, the LiveEdit Platform automatically created a sitemap.xml file for you. This file is used by the search engines to quickly check your website for new content and to update their indexes accordingly. These sitemap files are automatically updated as well.
Your can take a peek at your sitemap by adding /sitemap.xml to the end of your domain name. For example, yourwebsitename.com would have a sitemap located at yourwebsitename.com/sitemap.xml. This file will have links to a list of individual sitemaps that represent your site's pages (at /pages_sitemap.xml) and blogs (at /blog_sitemap.xml).
