When you’re starting to become an affiliate marketer, one of the easiest and most profitable ways to get started is through CPA affiliate marketing. CPA is a pay-per-click model that involves advertisers wanting to place their ads on your website so that you, as an affiliate, will earn money each time someone clicks on those ads. The only catch is that you don’t get to keep any of the money! But, if you do your job right and target people looking for what you have to offer, CPA can bring in good profits.
