Definition of A/B testing in Advertising

A/B testing, also known as split testing, is a method of comparing two versions of a webpage, advertisement, email, or other marketing asset to determine which one performs better. By presenting the two variants (A and B) to different segments of an audience simultaneously, advertisers can analyze the effectiveness of changes in elements such as headlines, images, calls to action, and layouts.


A/B testing is used to optimize marketing strategies and improve conversion rates by identifying which version of a marketing asset yields better results. It is a data-driven approach that helps marketers make informed decisions based on actual user behavior and preferences.
