Hello everyone! So yesterday I started with adwords and already got sales. I have a wordpress blog set up, promoting a clickbank product. My adwords ads are targeted to my wordpress page. From my wordpress page I build a php redirect to the clickbank product to hide my affiliate link. My problem is now that I have approximately 50 keywords which bring me traffic from adwords. Of course not every keyword is making me sales. That's why I would like to start to track the keywords to find out which keywords actually bring sales. Can anyone help me? Or can anyone recommend a good e-book to learn that?
