How it works
Once your application has been accepted you simply place a small piece of code right before the closing body tag in your pages. THis is extremely easy using WordPress since you will only have to do it once in your footer page of the Theme your using. Once you have the code inserted you will instantly see some of the words in your posts as links. When the links are moused over a buble with information will pop-up with information about the ad giving your visitors the ability to click n the ad and check out the deal. You can check this out on Success For Your Blog. Just look for an orange double underlined link.
How much will you make
Similar to Google Adsense you will be paid once your balance reaches $100. As far as the amount you make for each click, well that will vary in amount.
