For better understanding, I'll explain our principle of operation. Check the scheme below:
As you see, all the traffic coming to us is divided into segments, based on Traffic Type, GEO, Connection Type and OS. Then such segments (for instance, WiFi USA iOS mobile) are sent to a few marketing funnels (the top-quality creatives and relevant products offered for each user). On some offers each traffic segment is converted best of the rest. That is why it will be sent to this funnel to bring the highest possible revenue. You earn maximum - it's that simple!
