I have just been accepted by marketleverage and I found a cool offer where all they have to do is click the banner and register on the website and I earn $3. Is this how it works!? I have a newsletter I send out to people and can send them html, so the ad shows up in the email. So what I'm trying to say is how does CPA work? Does that banner have a special code in the URL to recognize my account specifically so I can make money?
