I have heard from one friend that it is possible. But there has to be some tricks. I need to connect my goal setting in google analytics with google adwords account. I have heard that you can make as much as you like ads but you will pay only when some certain action is done. Like thank you page after a sale is done. So can soembody teach me to do that like it should or at least give me some materials so that i could teach my self... I am willing to pay for something like that.
