THE GOOD :
Amazon have a lot of books on offer.
THE BAD :
Amazon’s Url tracking system is actually pretty bad – and you only get credit for a pruchase if people go in and buy books in the same visit that they clicked through from your site.
THE UGLY :
If they put books in their cart – and go away – and buy later then you do NOT get credit for it.
Summary :
We ran with Amazon for about 3 years – and despite a lot of clicks only around a small percentage ever turned into purchases – and as you’re only getting 5-7% of purchase price it never really grows to more than pocket change.
I do not beleive that Amazon’s affiliate system is a worthwhile monitization system for most affiliates.
