Definition of A/B Testing:

A/B Testing is a marketing method used to compare two different versions of an asset (like a webpage, email, or ad) to determine which one performs better. The two versions, often labeled as "A" and "B," are presented to different segments of an audience, and their effectiveness is measured based on the desired outcome (e.g., clicks, conversions).

Detailed Explanation of A/B Testing:

Think of A/B Testing like a friendly competition between two marketing ideas. Version "A" might have a catchy headline, while version "B" tries a more straightforward approach. By splitting the audience, we can see which version hits the mark and which one needs a little more seasoning. Whether it's changing a button color or testing completely different ad copy, this experiment helps businesses optimize their campaigns by making informed, data-backed decisions.
