A/B testing (also known as split testing) is the process of comparing two versions of a web page, email, or other marketing asset and measuring the difference in performance.
You do this giving one version to one group and the other version to another group. Then you can see how each variation performs.
Think of it like a competition. You’re pitting two versions of your asset against one another to see which comes out on top.
Knowing which marketing asset works better can help inform future decisions when it comes to web pages, email copy, or anything else.
To understand how A/B testing works, let’s take a look at an example.
Imagine you have two different designs for a landing page—and you want to know which one will perform better.
After you create your designs, you give one landing to one group and you send the other version to the second group. Then you see how each landing page performs in metrics such as traffic, clicks, or conversions.
