Out of the box, the AdRoll ABM platform will automatically display the following default website audience under Audiences > Website Audiences.
Visitors to Unsegmented Pages
By default, after you install the Pixel, all your website traffic will be automatically added to a default audience called Visitors to Unsegmented Pages. This default audience will serve as a catch-all to track all your website traffic until you start segmenting by creating your own Website Audiences.
As you create new Website Audiences, your default Visitors to Unsegmented Pages will no longer include any traffic captured by your newly defined Website Audiences. Any traffic to the pages that you define separately as a Website Audience will be excluded from Visitors to Unsegmented Pages.
