A/B Testing - What Is It and How Does It Work?

A/B testing is one of the most effective methods used by web designers and marketers to optimize their digital assets and marketing strategies. 

Let’s say you’re aiming to increase the number of people who sign up for your newsletter through your website. You want to know if the ‘Subscribe’ button is appealing enough for your site visitors. 

To test the theory, you’ll need to create two variations of the ‘Subscribe’ button. For example, version A might show a small, green button at the bottom of the page, while version B shows a large, orange button at the top.

You then direct half of your website traffic to version A and the other half to version B. Over the course of a month, you track how many visitors each version converts into newsletter subscribers. Based on the results, you decide to implement the version that leads to a higher newsletter subscription rate. 

This is basically how A/B testing works. You can test any element on a page, from the headlines to the font size and style. Every change is measured for its ability to engage and convert visitors. 

A/B testing is often a long process, but it’s worth it. By regularly testing changes to your website, you'll learn what makes your customers tick. And those insights can help you stay on track for online success.
