MORE INFORMATION | DOCUMENTATION | SUPPORT FORUM

A/B Testing for everyone. Just activate the plugin in your WordPress and discover what Nelio can offer you. The free version makes it extremely easy to run unlimited Heatmaps and A/B tests on low-traffic sites. And if you ever need more, you can purchase a premium plan and get an account to keep improving your WordPress!

10+ Reasons for Choosing Nelio

#1 – ❤️ Fully integrated within your WordPress

There’s no need to learn an external tool. Nelio A/B Testing has been designed to be simple and fast to use without ever leaving WordPress to create, edit or see the progress of your tests.

Our plugin lifts all the processing load from your own server and takes it back to our cloud. This way, A/B tests do not slow down your site or interfere with your hosting provider limits.

#2 – 🙌 Test everything!

You can create all kinds of tests not only for pages but for all the elements of your WordPress:

All your content. Improve your landing pages, write better posts, create alternative pages and custom post types, and start testing headlines.
WooCommerce Products. Test the content of your WooCommerce store. Find out how to improve your products and offers to get more sales.
Global tests beyond content. Try new themes, test different menus, templates or alternative widgets, modify your CSS rules, or create custom JavaScript snippets to change the appearance and behavior of your pages.
Heatmaps, Scrollmaps, and Confetti. Find out what your visitors are doing from different devices as they browse your website. They are a perfect companion of A/B tests, for they give insights on what to test next and help you understand the progress of your tests.

#3 – 🖌️ Compatible with Gutenberg and The Best Page Builders

Nelio A/B Testing not only works perfectly fine with the block editor but you can also create alternative content for your tests with your favorite page builder like Elementor, OptimizePress, SiteOrigin, Beaver Builder, Leadpages, Divi Builder, OptimizePress or Visual Composer.

#4 – 🤑 Conversions are the key to success

Nelio A/B Testing allows you to evaluate one or more conversion goals and, for each of them, track the important actions your visitors take: visiting a page, clicking on an element, visiting an external link, submitting a form (compatible with Contact Form 7, Gravity Forms, Nelio Forms, Ninja Forms, WPForms , Formidable Forms, HubSpot Forms, Elementor forms, and more), watch YouTube videos, adding or purchasing WooCommerce products, or after you’ve programmatically triggered your own custom JavaScript event.

#5 – 📐 Run tests targeted for specific set of visitors

If you’re interested in testing a subset of your visitors, you can do so using Nelio A/B Testing’s segmentation capabilities. Refine the audience you want to understand by defining the characteristics that are relevant for a specific test: country, language, device, referrer, date, time, and more!

#6 – 📈 Easy-to-understand results

Visitors and test results are displayed immediately. All details are very intuitive and provide you with the information you need to know which alternative is working best for you:

Day-to-day information that will help you understand what happens over time.
See at a glance how confident you can be of having found a winning variant.
Compare each variant with the original version.

#7 – 1️⃣One-click winner

Apply the winning version quickly and increase your income right away! Once you know which version is the best, make it your default page as soon as possible. You can do it with a simple click!

#8 – 🛠️ Cache Support and Server Load

One of our priorities is efficiency. The process of A/B testing a site is not necessarily at odds with performance. Nelio A/B Testing implements several mechanisms to reduce the impact of testing your site, such as support for cache systems in WordPress.

#9 – 🪪 Commitment to Data Privacy and Protection

From its very first day, Nelio A/B Testing was designed with the privacy of the end user in mind. From the perspective of your visitors and users, Nelio A/B Testing does not store any user-identifying information and can be integrated with your cookie consent banner and, thus, be fully compliant with the GDPR.

FAQ

Why should I use an A/B Testing Solution specifically designed for WordPress?

Smooth learning curve. There is no need to learn yet another tool.
Everything (from the creation of tests to the visualization of the results) is done from the WordPress dashboard you are familiar with, resulting in a well-known, perfectly integrated user interface.
Evolve your WordPress site easily. A native WordPress solution automates and simplifies the evolution of your site. Consider, for example, applying the winner alternative in your site as soon as the results are statistically significant. With a native solution, this is as easy as clicking one single button. With a generic tool, on the other hand, you would have to manually modify the page so that it integrates the changes you created in the (winning) alternative.
Fine-grained testing. The “testing unit” in a generic tool is the web page, since the HTML of the page is the only thing those tools have access to. A native WordPress solution, however, permits you to test any WordPress specific component, such as posts, pages, CSS, themes, child themes, and many more coming!

It is a great tool to perform A/B testing on your WordPress site. Very easy to setup.

andrebell82 29 di Avost dal 2024 1 reply

Over a week ago I uninstalled this because the only test option to appear was ‘Page.’ None of the other test options appeared in the test list. The other areas where icons should appear were just white background areas. But today after reading an online review of the plugin I reinstalled Nelio A/B split test. Now all the test options appear in the list. No clue what made the difference. When I uninstalled Nelio I also uninstalled all other plugins I was not using or were not useful to me within my Wordpress site. Wish I had noted what the other plugins were. Anyhow, this seems to be working as promised. Looking forward to tracking split tests of two variations of my landing page. Hopefully one or the other converts.

Fast support and a very easy-to-use interface. I recommend this for my design students to quickly test and iterate.

tbth 20 di Avrîl dal 2024 1 reply

The ROI on this plugin is truly outstanding. It’s much easier to use than other platform-agnostic split-testing tools. It’s so easy, in fact, that we can delegate the creation of quite advanced tests to non-technical members of our team. Writers or VAs can set up split tests in minutes. We’re able to test everything. What’s more, the support is fantastic. David really cares and goes above and beyond to promptly reply to support requests, investigate bugs, and fix them.If I could only keep one WordPress plugin it would be this one.

Setting up A/B tests with Nelio A/B is a breeze. Highly recommend to anyone looking to quickly deploy A/B tests from their own Wordpress. What truly sets it apart, though, is the amazing support team—always ready to help and go the extra mile.

We’ve just started using the plugin. First tests seem indicate that this plugin will be very useful. The big note here is that we had questions about the setup and results, and the support team was quick, and thorough and clear in their explanation–beyond what I’ve experienced in other services. As of now, a few weeks in, this plugin is highly recommended.
