About A/B Testing

What is Tests?

With Tests, Crazy Egg allows you to run experiments so you can measure the impact of a new idea. Your experiment can test out small copy refinements, persuasive messaging, or design changes.


If your goal is to get more sign-ups for a product demo, you can test out different call-to-actions, or button colors.

Who can use it?

Crazy Egg Tests is a feature that is only available to Early Access members.

How does Crazy Egg Tests work?

Tests work in the following three steps:

  1. When you create a test, you'll get a code snippet from Crazy Egg. Add this code snippet to your website’s HTML and you’re ready to go. You only need to add the code once.
  2. When visitors land on a page that is part of a test, Crazy Egg will deliver the Control and Variants at random. Crazy Egg uses multi-armed bandit testing to determine how traffic is allocated. 
  3. Crazy Egg records the performance of your pages onto your Results page.
