Cost per action: Formula, marketing & how to
What is cost per action (CPA) marketing and advertising?CPA or cost per action marketing is a pricing model used in mobile user acquisition campaigns in which advertisers choose a post-install action to measure, and only pay for users who engage in that action. That means in order for advertisers to pay, the user must see their in-app ad, install their app, and complete the action.
In CPA advertising, advertisers set the action to whatever they’d like, for example: signing up for a free trial, registering for a free download, buying a product, etc. Read about mobile CPA marketing for more information.
