What is A/B Testing?
A/B testing helps you understand what your audience wants. You make changes based on facts, not opinions. It improves the experience for your visitors. When your website, emails, or app are easier to use, people stay longer and do more.
A/B testing increases conversions. Even small changes can get more people to click, sign up, or buy something.
It reduces risk. You test on a small group first before changing everything. This helps avoid mistakes.

A/B testing is a way to find out which idea works better. You have two versions of something, like a website landing page, an email, or a button. Version A is the first one. Version B is the new one with a small change. You show one version to some people and the other version to other people. Then you check which version people like more.
A/B testing helps you make smart decisions. It stops you from guessing. You use real data to see what works best.
