You can whitelist or blacklist SSPs in the campaign set up.
You can whitelist one or many specific SSPs by selecting them. If you want to blacklist some of them, you can select all the other SSPs.
Our SSPs are categorized by traffic category. If you select mainstream, you will only get sources that sends mainstream traffic, don’t worry about getting the wrong type of traffic.
If you’re not familiar with the SSPs yet, we suggest to leave them blank, by default you will get traffic from all of them. You will then be able to see which sources brings you the best traffic and optimize.
You can also do the same for specific Domain, Publisher ID, Site/App ID, Appname, Device ID and User IP in the Filter List manager.
Make sure to link the filter list to your campaign.
