Definition:
CPA stands for Cost Per Acquisition, an online advertising billing model in which the advertiser pays for each action taken by the user. This action can be a sale, a registration in a form, the download of an application, or any other activity that the advertiser considers valuable.
The purpose of CPA is to optimize the performance of advertising campaigns, since it allows the advertiser to pay only for the results obtained, instead of paying for impressions or clicks that do not necessarily translate into meaningful actions.
The operation of the CPA is simple. The advertiser defines the action he wants users to perform (for example, buying a product, signing up for a newsletter, downloading an application) and agrees with the publisher or advertising network a price for each action performed.
User actions are then tracked through the use of cookies or similar technologies. When a user performs the defined action, the advertiser pays the agreed cost.
