Standard options when you create your campaign include the following:
- orientation (straight / gay / tranny)
- website sources (blogs / tubes etc)
- Desktop or mobile OS
You can also make blacklists where you exclude the traffic from websites or IP's/IP-ranges you don't want traffic from, or whitelists where you target the domains or IP's/IP-ranges you want traffic from and exclude everything else.
Black/whitelists are created here:
Make sure you also add the list to the campaign(s) you want it applied to.
