Explain A/B testing in terms of Google Analytics.

What exactly do you need to know?

A/B Testing is a way of comparing two versions of a web page and see which one is performing better. The version page can varied in title, headline, button or a page with different lay out and design. After creating 2 versions of the page, half of your traffic is shown the original version of the page and half are shown the modified version of the page. As visitors are shown both the versions, their engagement with each experience is measured and collected in Google Analytics dashboard and analyzed. From the data they provide, you can conclude on which page is performing better. You can read the manual on how to do A/B testing in Google Analytics to get better understanding.
