A/B testing (sometimes called split testing) is comparing two versions of a web page to see which one performs better. You compare two web pages by showing the two variants (let’s call them A and B) to similar visitors at the same time. The one that gives a better conversion rate, wins! A/B testing allows you to make more out of your existing traffic. While the cost of acquiring paid traffic can be huge, the cost of increasing your conversions is minimal.
