Split Testing Tools for WordPress for Better Conversion Rates

If you are using your WordPress website to sell products, promote services, or elicit any kind of response or actions from your readers, then the plugins we are looking at today have the potential to make your website a much more effective goal conversion tool.

By creating variations of your content, and split or A/B testing them against each other, you can increase the percentage of your visitors who complete a desired action. These content variations could be as small as changing the link text at the end of a post, right through to comparing two different theme designs against each other.

So whether you want to make more money from your website, or just generate more discussion and interaction around your content, it’s vital that you spend some time testing and optimizing your content to find out what works and what doesn’t.

Thankfully there are a number of plugins that give you the tools to do just that, all from within your WordPress admin interface. So to help you find the right tool for your website, here are the best WordPress split testing plugins.

Nelio AB Testing

Nelio A/B Testing for WordPress

Nelio AB Testing is a plugin that allows you to run A/B tests on your WordPress website in order to improve conversion rates and optimize your content and design.

The type of tests or experiments you can run include comparing two versions of a post – from small text tweaks, to the overall design and layout; headline testing; comparing themes; testing widgets; and comparing menu layouts. As you can see, pretty much any aspect of your website can be tested, from the call to action on a post, to the entire layout using the new A/B CSS test. You also get a powerful heat mapping tool to see exactly where your visitors are clicking on your posts and pages.

The controls for setting up and managing your tests are integrated seamlessly into your WordPress admin area. This means you don’t have to learn a new system, or manage another account to start running A/B tests on your WordPress website. However, as the service is cloud based, the computing takes place on the Nelio servers. This prevents any slowdown of your website occurring while the tests are running and the numbers are being crunched.

While the plugin for integrating the service with your website is free, as well as giving you access to a free 14-day trial, you will need to sign up to one of their paid subscription plans to use the service for an extended period.

With a 14-day free trial to take advantage of, you should be able to get a good sense of what Nelio A/B Testing has to offer. If your website gets enough traffic, you could even be able to improve your conversion rates and start generating more sales before the trial period is up.

WP Experiments

WP Experiments

WP Experiments is a plugin that lets you set up multiple tests on your website. This allows you to find out which elements of your posts and pages do the best job at helping you reach your conversion goals.

These variations of your content could include wording and image choices, through to changes in formatting and styling. You can also add custom JavaScript code to change other aspects of your site for the experiments. The demo video of WP Experiments does a great job of showing just what this plugin can do and is well worth checking out.

As your experiments run, the plugin will reduce the amount of times the poorest performing variation is shown to your users. This prevents you from missing out on conversions while you test, as would happen each time the highest performing content isn’t shown.

WP Experiments is a premium option, but there is a 14-day free trial you can use to start optimizing your website.

Title Experiments

Title Experiments

Title Experiments is another a/b testing plugin for WordPress. It’s been created by the same developers as the premium WP Experiments and could be considered the free or lite version of that plugin.

After installing Title Experiments on your website, you can begin testing out the titles of your blog posts to see which ones get the most attention from your readers.

From the post creation screen you can enter your title variations. Then, each time your posts are listed on your website, such as in in the recent posts widget, or the archive pages, those title variations will be tested against each other.

This plugin should not only help you increase the number of posts each visitor views on your blog, but also help you get better at writing post titles in general – a skill that is definitely worth cultivating.

Simple Page Tester

Simple Page Tester

Simple Page Tester lets you choose a post or page on your website that you would like to optimize. That page can then be tested against a modified copy, another exiting page on your website, or you can choose to create a new page to compare it to.

After giving your split test experiments a name you can then sit back and wait for the results to come in. While there is a free version of this plugin available, it only allows you to see how many visits each variation has received. If you want to know about goal conversion rates and other more useful data, then you will need to upgrade to the premium version.

Despite the free version of Simple Page Tester lacking in useful features, the premium version is available for a relatively affordable one-time fee.

WordPress Calls to Action

WordPress Calls to Action

The free WordPress Calls to Action plugin allows you to create calls to action for your website. These CTAs can then be tested against each to find the one that your visitors interact with most favorably .

These calls to actions can range from simple links, right through to social media buttons, file downloads, and a lot more. The plugin includes a selection of templates for creating your call to action, although you can start from a blank canvas. Those templates can all be customized in a number of ways by using the appearance settings. You can then add your custom message using the WordPress editor.

The calls to action can then be inserted into your WordPress posts, pages, and other areas where you want them to be displayed. Furthermore, once you’ve created a call to action, you can then create a variation of it, and let the testing commence.

If you want a tool for building your own reusable call to action buttons, with the ability to then split test them against each other, then this free plugin is a good option.

Conclusion

As we’ve just seen there is a handful of well-designed and useful plugins for carrying out A/B and split testing on your WordPress website.

Whether you want to start off slowly with a plugin like Title Experiments and compare your post titles, or dive deep into testing and optimizing all aspects of your website with a service like Nelio A/B testing, there is an option to suit your requirements and budget.

    I would also add OptinMonster to the list. It's meant for quick email signup forms, but they allow for A/B testing within the plugin which works great. It's a really nice tool and has done a lot to help us grow our email list.
    • Joe Fylan says:
      Yes Jonathan, I was thinking of adding plugins like OptinMonster that include split testing as part of their functionality, but ran out of space!

    Great review Joe! :) I think Jason did a really good job with WP Experiments, which is a really good option for landing page builders like Beaver Builder or Thrive Content Builder
    • Joe Fylan says:
      Thanks! Yes its a great plugin. I'm sure more people could make use of it then are already, especially if they are selling online. Using it alongside a landing page builder tool is a really great idea and allows you to quickly create attractive pages and then test them against each other.

      Hum...that's a great question. My guess is you would have to create 2 new files header-one.php and header-two.php and in your main header.php add a function that randomly loads a distinct header which different tracking code. I tried doing some research on this and wasn't able to find any good tutorial on the matter, sorry :( Maybe you could use a heatmap plugin to see if people are taking any action on your current header for a week or so and then switch the header for another week or so to compare.

    I developped an alternative to the above options because I was dissatisfied with the different offerings available, it is called GA Experiments+. At this point, I only developed the first tier which is free and serves as an MVP while still allowing to do simple AB tests or complex ones if you know some basic CSS and/or code (or just ask your favorite developer). It is powered by Google Analytics and is compatible with Google Tag Manager. Find the plugin here : https://wordpress.org/plugins/ga-experiments-plus-dev-edition/

      Nice looking plugin, thank you for sharing with the community. The only thing is if you can change out the yellow, red, green icons for something more minimal (hopefully using CSS) it would keep the UI much nicer.

        Thanks for your input AJ. I'm actually tweaking some UI details and improving performance as we speak. As I said, the current version serves as an MVP so I'm letting people know about it precisely to get more feedback, improve the product, and evaluate the commercial potential of the next two tiers. What would you have in mind to replace the icons? If you would like to be a beta tester, I have almost everything setup to provide pre-release versions to beta testers (I'm only missing automatic e-mail notifications, no big deal). Feel free to contact me using one of the methods you can find on the Wordpress plugin's page. Also be sure to check the "Other notes" page for the planned features of the next two tiers. Mostly, the plan is to make it more user friendly and not require programming for advanced tests but there are a couple of original features planned. I'll mostly be focusing on acquisition in the next weeks/months but get me excited over a feature and I might very well provide it! Thanks again!
