Website Campaign is based on targeting websites from a site list.
To create a Site List follow the following steps:
a. On the dashboard at the left hand side, click on 'Site List' to view your saved site lists or create a new one.
b. On the Top right navigator, click on "+ New Site List" to create a new Site List.
c. A new popup will appear, now enter a name to the new Site List you wish to create, select whether this will be a white-list (sites to target) or a black-list (sites to un-target), and type domain names in separate lines in the designated area.
