PPA (Pay-Per-Action)

PPA is the acronym for Pay Per Action, also known as Pay Per Acquisition.  PPA refers to the advertising process by which an advertiser pays the publisher every time a visitor takes a pre-determined action, such as buying a product or service, or submitting a form.  This is not to be confused with PPC (Pay Per Click) where the advertiser pays for a click regardless of whether an action is taken after the click.
