The rates for each advertisement are specified by its creator. Peadler not only allows you to freely share content, but also create paid advertisements yourself for other users to share. You can specify how much you are willing to pay each click someone gets for you, as well as many other criteria such as gender/age/geolocation and more. You simply create an account, add credit to your online wallet via PayPal, then create an advertisement and invite other users to share.
