To help search engines better understand your site's hierarchy and index your site, it is recommended that your website include an xml formatted sitemap, typically found at: http://yourdomain.com/sitemap.xml
NOTE: excluding urls for site content from XML sitemap does not flag the content for exclusion from Google & Bing's search indexes. See instructions for setting a NoIndex metatag here.
Most WordPress websites built and deployed by Eastern Standard include this feature (through the XML Sitemaps Plugin [https://wordpress.org/plugins/xml-sitemaps/]). For these instances, the XML Sitemap is setup to reflect all the main menu items/links.
