Searching for the "right" affiliate program on the "right" network can be challenging but newly launched Affspy aims to change all that.
The free affiliate intelligence tool allows users to enter a keyword and find the best performing offers as well as which networks pay the most for each - that's important as affiliates can findwe. I played around with the service and found several reputable affiliate networks including RevenueLoop, ClickBooth, Advaliant, NeverBlue and others.
AffSpy is definitely an excellent service that affiliates should try out and one that, if you're an affiliate network, you should consider joining.
