It depends where you will send the traffic. but don't expect too much volumes as the CTR these days is not that big, so I will advice you to add other sourcetypes as well like pops or redirects. a combination of these 3 will be the best. but of course it's all about testing and optimization. But buying traffic from one tube and sending that to another tube will be useless.
In fact we work with many media buyers who buy traffic from websites directly or adnetworks and they send the traffic to us and we monetize it, based on the volumes that seems to be a profitable case ;-)
