A/B testing - or "split" or "bucket" testing - is the practice of comparing two instances of a webpage, or an app, to identify which one performs better for the users. Participants are assigned to view either the original page (A), or the variant (B) at random, and a statistical way of analysis determines whether one page produces a better result than the other. A/B testing can be used with anything: email campaigns, landing pages, webpages, product pricing, and marketing communications.

Overall, this systematic approach to optimization allows a business to ground its decisions in real user data, from more informed decisions leading to better results to the effective use of resources.
