A/B Testing
A/B Testing is a method used in marketing to compare two different versions of something (like websites, emails, or ads) to see which one works better. Think of it like showing two different store window displays to shoppers and tracking which one brings in more customers. Companies use A/B Testing to make better decisions about their marketing materials by testing real customer reactions rather than just guessing what might work. This approach is also sometimes called "split testing" or "bucket testing." It's a key tool used by marketing teams, researchers, and digital analysts to improve customer experience and increase sales.
