Create a site—ArcGIS Enterprise Sites | Documentation for ArcGIS Enterprise

To create a site, follow these steps (learn more about sites):

Sign in to ArcGIS Enterprise.
Click New on the Sites card.
Provide a name for your site and click Create site.
Caution:
The name you provide is used to automatically generate your site's URL. While you can configure this URL at anytime, it's best to determine the format of your URL early to avoid broken or forwarded links as you build your site.
Once your site has finished activating, the site editor automatically opens where you can configure your site's URL and begin designing its layout. To learn more, see Site editing basics.
