Google Search Console provides detailed information and allows site admins to control how their site is presented in Google search results.
One of the ways this is done by submitting a "sitemap" to the Search Console. The sitemap is an XML file that's generated by Composer. It provides Google with a detailed breakdown of all of the public pages on your site that you want to be indexed by Google, as well as how they relate to one another (that is, which pages are children of other pages, which ones are main section pages, etc.).
You may occasionally need to resubmit your sitemap in Google Search Console to draw Google's attention to pages that have changed or moved. This makes sure that Google always directs searchers to the right pages on your site.
Access Google Search Console (previously called Webmaster Tools) at https://search.google.com/search-console/welcome.
Log in using the credentials associated with your Google Analytics account.
Once you are logged in, click the main menu and use the dropdown arrow to select your website as the "Property." If you have many sites, use the search instead.
If the site has not already been added, click on "Add property" and follow the instructions detailed in the article: Configuring Google Search Console.
From the property overview screen, click on "Sitemaps" in the left-hand navigation.
If there isn't an existing sitemap, use the "Add a new Sitemap" option to add one.
For Composer sites, use: https://www.yoursite.com/fs/pages/sitemap.xml
For Page Manager, use: https://www.yoursite.com/xmlsitemap.cfm
If your sitemap is already added, you can view the index coverage report by clicking on the icon on the right.
