Here is a list of affiliate marketing metrics often used by affiliate managers to make informed data-driven decisions.
How to Use Affiliate Marketing Metrics
Before we dive in, it’s important to note that many affiliate marketing stats are available in your dashboard. That alone can be overwhelming, so start by jotting down the numbers that take priority.
