AWIN is probably best for experienced affiliates who can hit the ground running without a lot of guidance or feedback from the network. There is a $5 fee charged to apply to become an affiliate, but if you’re approved, the $5 will be added to your account. If your application is denied, however, you will lose the $5 fee. AWIN operates globally, but it is most heavily concentrated on British and EU merchants.
I concluded that having read a product review, people felt more informed to make a purchasing decision. As a result, if they did click a link after reading the review they were more likely to buy the product. Those clicking on the top link seemed to be more in a ‘surfing’ mode. They clicked on the link less because they wanted to buy it but more out of interest to learn more. Some bought the product and some bought other products once they were ‘in the door’ at Amazon.
