What are some Popunder/Pop up ad Networks? I know: Adversal.com Paypopup.com Popupad.net And maybe Clicksor.com. How do these Pop under ad Network attract users to join? Are they all generic Pop ups? If you are with one of these networks why do you use them?
I'm having a hard time understanding what you're asking here, are you asking how they attract people to buy pop up/pop under traffic through them? Usually some of them will offer exclusive packages on well known sites that have good traffic as a way to sell high end clients. Pop ups and pop unders are not always ineffective for marketing, especially if done on a larger scale. you can use the network A. to buy traffic or B. to sell traffic... Hope I helped you figure something out you were looking for
