A/B testing is a critical digital marketing technique that can help your business improve its website’s performance, usability, and SEO.

But what is A/B testing?

And how can you make the most of it for your business?

In this post, we’ll provide a comprehensive definition of A/B testing, discuss its importance in SEO, explain how it can help with your SEO efforts, and offer some best practices to help you get started.

What Is A/B Testing?

A/B testing is a technique used to compare different versions of a web page or app to gauge which one works best.

You can use A/B tests to assess anything from the design of a web page to the copy on a button.

Difference Between A/B Testing and Usability Testing

It’s important to note that A/B testing is different from usability testing.

Usability testing is a technique used to assess how easy it is for users to use a website or app.

A/B testing, on the other hand, compares different versions of a page, headline, or other types of copy.

How Does A/B Testing Work?

A/B testing works by showing different versions of copy to different groups of users.

In an A/B test, visitors randomly get shown either the “A” version or the “B” version of a page.

The version that performs better then gets used as the new baseline for further testing.

To set up an A/B test, you’ll need to create different versions of the page or app that you want to test.

You might use two completely different versions or start with smaller variations.

What Is the Purpose of A/B Testing?

The purpose of A/B testing is to find out which version of your copy works best.

By running A/B tests, you can make informed decisions about how to improve your website.

Different Types of A/B Testing

Here, we’ll take a look at three types of A/B testing you can use with your search engine optimization efforts.

  • Split Testing: Split testing is the most common type of A/B testing. It involves creating more than one version of a page, then showing each version to a different group of users. The goal is to see which version performs better in terms of conversion rate or another metric.
  • Multivariate Testing: Multivariate testing is similar to split testing, but it involves testing multiple page variations at the same time. It is a type of A/B testing often used to test different combinations of copy, design, and layout.
  • Multi-Page Testing: Multi-page testing involves testing multiple pages of a website at the same time. It is helpful for testing things like the user journey or the effectiveness of a sales funnel.

Example of A/B Testing

In one of their A/B test case studies, Moz.com found a surprising result when they saw a 20% dip in rankings in one of the tests.

The drop resulted from A/B testing higher-volume keywords against lower-volume keywords in title tags.

Interestingly, the lower-volume keywords performed better.

Does A/B Testing Affect SEO?

A/B testing can have a positive effect on SEO for WordPress sites.

For instance, if you make changes that improve the user experience, such as making it easier to navigate your site, your A/B tests will have a positive effect on your SEO.

Why Is A/B Testing Important for SEO?

A/B testing is important for SEO because it allows you to make informed decisions about the changes you make to your website.

By running A/B tests, you can determine which changes are most effective at improving your website’s performance in search engines.

Is A/B Testing Necessary?

A/B testing is not necessary for SEO, but it is helpful.

While you can achieve successful SEO rankings without A/B testing, you can improve those rankings by implementing A/B testing.

How Long Does It Take for A/B Testing To Work?

The amount of time it takes for A/B testing to work depends on the size of your website and the complexity of the changes you’re making.

A/B tests on small websites can take a few days to complete, while tests on large websites can take weeks or months.

Simple tests like changing a button’s size can show results quickly.

More complex tests, like changes to a website’s theme, may take longer to show results.

Process of Setting up an A/B Test

Here are factors you should consider when undergoing the process of setting up your next A/B test.

  • Step 1: The first step in setting up an A/B test is to choose your goal. There are several factors you can test, such as the color of a button, the copy on a web page, or the layout of a website.
  • Step 2: There are several A/B testing tools available, such as Google Analytics, Optimizely, and Visual Website Optimizer. Each tool has unique features and pricing plans.
  • Step 3: Once you’ve chosen your goal and decided on an A/B testing tool, it’s time to create your A/B test. The process of creating an A/B test will vary depending on the tool you’re using.
  • Step 4: After you’ve created your A/B test, it’s time to run it. Once your A/B test is active, you’ll see the results of your A/B test and determine which version performs better.
  • Step 5: Stop your A/B test after determining which version performed most effectively. Doing so will allow you to implement the winning version on your website.

How To Set up an A/B Test

Now that you know the process of setting up an A/B test let’s review how to set up a more specific scenario.

Step 1: Choose Your A/B Testing Goal

For this example, let’s suppose you want to test a button’s color on your website.

Step 2: Choose Your A/B Testing Tool

You’ll need to select your A/B testing tool before proceeding further. For this example, we’ll use Google Analytics.

Step 3: Create Your A/B Test

Next, you’ll create your A/B test.

In Google Analytics, you can create an A/B test by going to the “Experiments” section and clicking “Create Experiment.”

Step 4: Run Your A/B Test

After you’ve created your A/B test, it’s time to run it.

Google Analytics will automatically run your experiment and determine which version performs best.

Step 5: Implement the Winning Version

Once your A/B test is complete, you’ll implement the winning version on your website.

In this example, if the button with the blue color performed better, you would permanently change the button on your website to blue.

A/B Testing Best Practices

Use the following best practices as you set up your A/B tests.

1. Always A/B Test One Variable at a Time

You should focus on one variable at a time. It may seem obvious, but it’s easy to get caught up in testing multiple variables simultaneously.

Testing too many items at once will only serve to muddle your results.

2. A/B Test for a Statistically Significant Amount of Data

A/B tests are all about comparing two sets of data.

You need to have a large enough sample size in each group to produce reliable results.

A good rule of thumb is to have at least 100 conversions in each group.

3. Use a Randomized Control Group

A randomized control group is a set of users that do not get exposed to the new test.

The group provides “control” against which you can measure the results of the new variation entered into the picture via your A/B test.
