WordPress A/B Testing

If you want to have a great WordPress site, you have to make sure it carries out the best performance. All elements have to work together in harmony, so your site has the best possible user experience.

WordPress A/B testing can help you perfect your site. It helps to find what improvements to make for better site engagement.

In this article, we’re going to show a hand-picked list of best A/B plugins for your WordPress to help you with the task.

What is A/B Testing?

Before we get into some of the finest WordPress A/B testing plugins, let’s take a look at what it is and why it is so important for your website improvement.

A/B testing, or also known as split testing, puts elements of two online pages side by side and observes which one displays the best result.

The existing page that you want to compare is called an A, while the other page that you build for comparison is referred to B or the variant. They will compete with each other to show you which implementation can perform better.

There are multiple elements that you can put A/B testing on, such as:

  • Logo
  • Banner
  • Ads placement
  • Buttons
  • Content
  • Footer
  • Page layout
  • Widgets
  • Calls to action

Both the mobile and web version of these elements will have the same treatment so you don’t have to worry about the different outcome.

We’ll provide you with examples.

Let’s say you want to know if the small and descriptive banner on your site can attract more users than a big and minimalistic one. To find out, conduct an A/B test on it and see which brings better results.

Why Is A/B testing Important

The main goal of using A/B testing is to provide relevant information about a site’s element so you can improve based on the results.

In other words, you will have a data-driven decision in building the best version of your website.

There are certainly several metrics that can be determined by using the test, such as time on page, page views, and conversion rate. They provide useful insights as they can indicate a site’s success level.

For instance, since your webpage’s appearance most likely influence the view count and time spent on it, the test result will tell you what’s the preferred layout for your customers.

Other than that, you’ll have a credible input on how to optimize your website’s call-to-action (CTA), buttons, and ads placement, which lead to a higher conversion rate.
