CPA (cost per action)

By Michael Moncur (November 16, 2004)
In Web advertising, CPA ads are ads that require the user to perform an action before you receive a comission. This action is typically one of the following:
  • Filling out a form (cost per lead). You are typically paid a set amount for each user that completes the action.
  • Making a purchase. You are typically paid a percentage commission on each item sold.

CPA ad programs are also known as affiliate programs.
