How CPA Affiliate Marketing Works

At its core, CPA means cost per action. You earn a commission when a user takes an action. The action can be a lead, a form submit, an app install, a free trial, or a sale.

Here is the flow:

You apply to a CPA network and get approved.
You choose an offer and get a unique tracking link.
You send traffic to a landing page or direct link.
A user completes the action the offer needs.
The network tracks it and pays you a set payout.

This model is great for control and scale. You pay for clicks, but you get paid for actions. Your job is to make the math work. This is the heart of what is cpa affiliate marketing.
