Cost Per Action (CPA) Explained

What is Cost Per Action (CPA)?

Cost Per Action (CPA) is a Facebook advertising metric that measures the cost incurred by an advertiser for a specific user action, such as a click, form submission, purchase, or app install.

It helps advertisers understand how efficiently their campaigns achieve desired outcomes and optimize their budgets by focusing on actions that align with their goals. CPA is particularly useful for performance-driven campaigns where every action directly impacts ROI.
