I have a small blog about movies. I want to place a banner 728x90 pixels in the header of my blog. First, I thought about Amazon Prime. They pay $2 for signup for 30 day free trial. Today I saw Netflix offer on commision junction. They pay $12 for signup. I already promote some Amazon products on my other websites. That is +1 for Amazon Prime. Netflix pays More. +1 for Netflix. Where I can make more conversions and make more money? Where is more competitors?
