CPA in Affiliate Marketing

CPA is also the term used with relation to the sale of Affiliate Merchandise, where you carry a link or image of a product on your site, and when the user clicks on it to purchase it, your site sends them to a merchant site to complete the transaction.  Once purchased, you receive a percentage of the sale to the consumer.

The range of commissions on a CPA deal varies widely. It could be as little as 2% or as high as 50% or more. The value of the affiliate program is in the rate of payment AND the rate of conversion (which is how many people actually decide to purchase the product).
