What is it?

A/B Split, commonly referred to as A/B Testing, is a systematic approach used in marketing, web design, and product development to compare two versions of a webpage or product feature against each other to determine which one performs better. Essentially, it involves showing version 'A' (the control) and version 'B' (the variant) to two similar audiences and measuring the effectiveness of each based on predefined metrics such as conversion rates, click-through rates, or user engagement levels.
