How to make money using CPA??

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?

your affiliate code is the html of your banner - when people click on the afilliate code - it takes them to the website but the company knows you sent them. usually some type of dynamic script is used.

So I just have to copy and paste the HTML code they provide me and whenever people click on it and register on the website I make money? Simple as that?

What are some good methods for small traffic websites that make 1k unique hits per month?

also, some offers do not allow to be sent by email. so you better check that out. i'm not sure if it means any email at all, or if it means you can only send to people that opt in. but you better check, otherwise you could get banned.
