i have a product review site that i send customers directly to vendors like CJ and Amazon.

every A/B split testing program i've seen so far demands you have a control, variation and a conversion page (meaning the page customers click to to complete conversion).

however they say if the conversion page is not on your page, you must install tracking code on that page. well how do you install a tracking code on Amazon?

instead of being able to send traffic directly to the sales pages, i must create another page (my conversion page) then provide a link to the sales pages. this i believe really hurts my sales because it's giving people one extra reason not to click through to the sales pages.

is there anyway to split test affiliate links while not losing having to add an extra click along the way?
