I just recently discovered the existence of CPA gateways; where site visitors are forced to fill out an offer before viewing site's content. What is not clear to me what value the CPA gateway adds to the equation. What is the role of the CPA gateway network? A)CPA gateway networks are just like Azoogleads.com in that merchants contract with the CPA network to run their affiliate program. B)CPA gateway networks are just a middle man offering CPA offers for which any webmaster could independently apply for and thereby cut the CPA gateway out of the loop. If this is the case then the CPA gateway network is not offering enough value, for me, since I am pretty sure I could buy or create my own gateway script. If A) from above is correct; then can I assume that the merchants of the CPA gateway networks are know and give their blessing to their offers being incentives?. How does this compare to adsense in earnings?
