The best part of cost per sale advertising is the fact that you do not actually have to get involved in the direct selling of any product or service
. Your job is just to make sure that people get to the site that is selling the product. In other words all you really have to do is drive traffic. The math is simple. The more traffic you drive the more you commission you stand to gain. There are two things that you must remember in order to be effective, one is to learn how to maximise your traffic and two is to choose a product that is not very common.
