Submit Your Site to Google Search for Indexing

Prerequisites

A host / super user account. Hosts have full permissions to all sites in the DNN instance.

Go to Persona Bar > Settings > SEO.
Go to the Sitemap Settings tab.
Copy the Sitemap URL and save it for later use.
Add and verify your site in Google Search Console so you can submit your sitemap's URL for indexing.
1. Go to Google Search Console.
2. Open the Add property dropdown and click Add property.
3. Enter your site URL in the Add property window and click Continue.
4. Copy the filename provided by Google in the Recommended verification method (HTML file) section.
5. In the DNN Sitemap Settings page, in the Site Submission section, paste the filename to the Verification field and click Create.
6. In the Google Verification page, click Verify.
  
  You will receive the confirmation message Ownership verified.
7. Click Go To Property underneath the confirmation message.
Choose Sitemaps from the navigation menu at left.
Under Add a new sitemap, enter the sitemap URL from step 3 and click Submit.

Your DNN sitemap will then be available for Google to index, although there is no set timeline for Google to crawl a newly submitted site. See the Google documentation Manage your sitemaps for next steps, including resolving any errors in the sitemap.
To find which pages from your site are currently visible in Google searches, search Google for "site:" followed by your site's URL. For example, searching Google for site:dnnsoftware.com will return results from the domain dnnsoftware.com.
