Your mobile website name is the way Google represents how your URLs are displayed on mobile devices:

  • Mobile search results no longer show the actual page URL, but instead show a breadcrumbs-like format of the URL structure. This is rolling out worldwide.
  • The breadcrumbs-like information can show the site name in place of the domain name. This is rolling out in the U.S. only for now.
To configure yours, go to the gobal settings as shown below:

Enter the short description you want to use in mobile search results in the Website Name box.  

If you want to specify a different home page when your site is viewed on a mobile device, you can select it from the Mobile Home Page drop-down menu. This practice is strongly discouraged, your website should display a mobile responsive version of your home page.
