Editing Cost per action (section)

==CPA used as "cost per acquisition"==
CPA is sometimes referred to as "cost per acquisition", which has to do with the fact that many actions which advertisers are optimizing towards are about acquiring something (typically new customers by making sales), although this has led to confusion in the marketing industry as to the correct meaning of CPA. Adding to the confusion, "cost per acquisition" may be used where it actually is [[customer acquisition cost]] (CAC).

=== Formula to calculate cost per action===
Cost per action (CPA) is calculated as the cost divided by the number of actions being measured. So, for example, if the spend is $150 on a campaign and the actions attributed to this campaign is 10, this would give the campaign a cost per action of $15.
