A/B testing, also known as split testing, is a method used in digital marketing to compare two versions of a webpage, ad, or other marketing elements to determine which one performs better in terms of specific metrics such as conversions, click-through rates, or user engagement. This testing involves showing two variants (A and B) to different segments of your audience at the same time and tracking their interactions to see which version yields better results.

The core purpose of A/B testing is to make data-driven decisions, which can lead to improved marketing effectiveness and optimize user experience. By analyzing which variant resonates more with the audience, marketers can refine their strategies and subsequently enhance performance.

While the other options touch on important aspects of digital marketing, they do not encapsulate the essence of A/B testing. For example, analyzing demographics, determining the best time for posting, or evaluating email campaign effectiveness, all serve different objectives that do not specifically involve the comparative element inherent in A/B testing.
