CPA (Cost Per Action / Acquisition)
CPA can mean a payout model where you earn a fixed amount per completed action (a sale, signup, or lead), or your cost to acquire a customer when buying traffic.
Why it matters for your earnings
CPA offers pay a flat bounty regardless of order value, so they can beat percentage offers on cheap products — and knowing your own CPA tells you the most you can spend to win a customer.
