What is A/B Testing?

A/B testing, also known as split testing, is a method of comparing two different versions of a webpage to determine which one performs better. It’s a powerful tool that can help you optimize your website and improve user experience. However, many WordPress users are not familiar with A/B testing or don’t know how to do it effectively on their sites.

If you’re looking to increase your website’s conversion rate and improve user engagement, A/B testing is a great place to start. In this article, we’ll show you how to do effective A/B testing with WordPress, step-by-step. You’ll learn what AB testing is, why it’s important, and how to set up and run your own AB tests on your WordPress website. So, let’s get started!

Elements You Should be A/B Testing on Your WordPress Site


The headline is the first thing visitors see when they land on your site. A/B testing different headlines can help you determine which one resonates best with your audience. Try different variations, such as longer vs. shorter headlines, questions vs. statements, and emotional vs. factual.

Calls to Action (CTAs)

CTAs are critical to the success of your site. A/B test different versions of your CTA buttons, such as color, size, and text. You can also test the placement of the buttons to see if they perform better in different locations on your site.


Images can have a significant impact on the effectiveness of your site. A/B test different types of images, such as product images vs. lifestyle images, and see which ones perform better. You can also test the size and placement of images to see if they have an impact on your conversion rates.


Forms are a crucial element of your site, especially if you’re running an e-commerce store or collecting leads. A/B test the length and complexity of your forms to see if they affect your conversion rates. You can also test different form fields to see which ones are necessary and which ones can be removed.


The navigation of your site can impact how long visitors stay on your site and how many pages they visit. A/B test different navigation menus and see which one performs better. You can also test the placement of the menu and the number of items in the menu.

How To Perform A/B Testing With WordPress

Step 1: Define Your Objective

Before starting an A/B test, it’s important to define your objective. What do you want to achieve with the test? Do you want to increase conversions, clicks, or engagement? Once you have a clear objective, you can create two versions of the same page, each with a different element to test.

Step 2: Choose an A/B Testing Tool

There are several A/B testing tools available for WordPress, such as Google Optimize, Nelio A/B Testing, or Convert. Choose a tool that suits your needs and install it on your WordPress site. Most tools offer a user-friendly interface that allows you to create, launch, and track experiments easily.

Step 3: Create Your Variations

Using the A/B testing tool, create two versions of the same page with a different element to test. For example, you can test different headlines, images, call-to-action buttons, or page layouts. Ensure that the variations are distinct and measurable so that you can track their performance accurately.

Step 4: Launch the Experiment

Once you have created your variations, launch the experiment using the A/B testing tool. The tool will randomly show each version to a portion of your website visitors, and track their behavior. Ensure that the experiment runs long enough to gather sufficient data to make an informed decision.

Step 5: Analyze the Results

After the experiment has run for a sufficient period, analyze the results using the A/B testing tool. Look at the data to determine which version performed better in terms of your objective. If one version outperformed the other, implement the changes on your website permanently. If the results are inconclusive, consider running another experiment with different variations.
