If you are already tracking a site in SharpSpring, when you attempt to enable that site as a landing page site you will see the following message:
In order to begin building landing pages, you will need to create a subdomain. In the below example, bryantobin.com is currently being tracked in an instance of SharpSpring, so the subdomain blog.bryantobin.com was created to be the landing page site.
Example subdomains: connect, go, social, learn, blog, digital, events
Once your subdomain is created, you simply put that value into the page configuration for the landing page tool. Make sure the checkbox "Uses landing page builder" is checked.
Once our subdomain is in place, we can begin creating landing pages in SharpSpring.
