I just watched a video that goes in to great detail on Google optimizer. I was very transliterated in the face that you can do experiments on conversion rates when visitors click to place an order. I am an affiliate marketer so there are links to buy pages on my monetizing pages.

Since the visitor is taken to an affiliates site to buy how can I use Google optimizer to do research and experiments. My best money maker has 5 pages that promote the product from various points of vies and each page has different keywords, Please let me know how to use Google optimizer for this purpose.
