What Is A/B Testing in Affiliate Marketing?
A/B testing, also known as split testing, is a method where two (or more) versions of a landing page are shown to different segments of your audience to see which one converts better.
In affiliate marketing, this could mean testing:
-
Headlines and subheadings
-
Call-to-action (CTA) buttons
-
Page layouts and colors
-
Lead capture forms
-
Offers or even traffic angles
Why it matters:
-
Higher conversion rates
-
Lower cost per acquisition (CPA)
-
Increased return on investment (ROI)

-
Speed and ease of test setup
-
Detailed performance analytics
