What Is A/B Testing?
A/B Testing, also known as split testing, involves creating two different versions of a webpage or product feature to see which one yields better outcomes. By randomly showing one version to half of your audience and the other version to the remaining half, you collect data on user interactions such as clicks, time spent, or conversions. This controlled experiment helps in understanding the impact of changes and making informed decisions based on statistical evidence.
