Hi everyone. I need a help. I'm kinda new to affiliate marketing and I cannot figure out the difference between CPA and 3d part networks. Could someone explain it to me? I've read a lot of forums and sites and still I feel that both CPA and 3d part networks work as a marketplace where advertisers and publishers meet. I know that CPA networks only pay for certain action made, i.e. sale or lead. As I undesrtand CPA network is a type of 3d part network, but in this case it would not be presented as a different type of network. So I'm totally confused.
