Update the sitemap of a site
The sitemap reflects your site’s structure at the moment when the sitemap was created. If you add new pages to your site, the sitemap won't update automatically. To update it:
Go to the Refined Administration.
Click Sites in the left-hand menu.
Select the site.
Click the Configuration tab.
Scroll down to the Sitemap heading and click the Refresh sitemap button. The sitemap’s URL will stay the same: (subdomain).(domain.com)/sitemap.xml. Don’t forget to resubmit the sitemap to the search engine(s) of your choice.
