'''CPA''' (Cost Per Action) represents an advertising campaign pricing model which earns income based on direct results. Other advertising campaigns pay for a given number of impressions ([[CPM]]) and even for a given number of visitors ([[CPC]]). Some of the most used forms of CPA are affiliate and referral programs. Using banner ads as an example, the CPA represents the cost the advertiser pays to the website publisher every time a specific user-action is initiated. <ref>[http://www.investorglossary.com/cpa.htm CPA definition]</ref>

*''Pay per Lead affiliate program'': Represents an online advertising payment model which supposes that the payment is done based on lead information. A lead is generally understood as a sign-up process, which does not involve cash transactions. A lead may be represented by an email address, phone number or a set of such type of information. No payment is due for the visitors that do not sign up. Risks are involved in the case of Pay per Lead programs since false leads can be created, but these are generally easy to spot.  <ref>[http://www.webmaster-affiliates.net/affiliate.php?type=2 Affiliate Programs]</ref>
