Jensen's site builder comes equipped with the ability to create templates that may be deployed any number of times on unique domains.
You might test Google's random ranking factor by creating 5 brand new sites, all targeting the same keywords and see which ones perform best out of the gate.
You could also create a niche service specific site for one Geo and quickly deploy it across any number of other geos as well.
To better explain the templating engine, imagine we wanted to create a simple 3 page plumbing website used for PPC traffic. We could make our homepage with the headline "Emergency Plumbing Services in {{city.name}}".
You could also enter your phone number in the template as the Phone Number token "{{phone_number}}".
When you go to deploy your site, the deployment wizard will allow you to choose a city and attach a call tracking phone number to the site. The templating engine means you can deploy the template any number of times with different geos and unique site specific variables like tracking numbers and URLs. In this specific case you can use a high converting site for San Diego traffic on your "SanDiegoPlumbing.com" domain while also getting traffic in Charlotte with your "CharlotteEmergencyPlumbers.com" domain, showing Charlotte specific content to those visitors.
Here is the complete list of template variables:
When you want to insert a token into the site make sure to use the double curly bracket syntax: {{variable_name_here}}. The variables in the table above are saved for use by the system, but you can make any variable you want and you'll have access to set them on a per site level during deployment.
