What is AB testing in UI design?

A/B testing (split testing) is a quantitative method of finding the best performing version of CTA, copy, image, or any other variable. To start A/B testing, prepare two or more versions of a single element, randomly split your user group in two, and see which version performs better.

How do you avoid network effects in AB testing?

The best way to deal with network effects is to group customers who are similar and measure the aggregated difference between the treatment and the control. This way, there is less spillover between treatment and control groups.
