8 WordPress A/B Testing Tools for Quick Conversion Wins

Did you know that roughly 44% of businesses use A/B split testing tools to optimize their conversions? We think that number should be higher! Using A/B testing can potentially result in improved user experience, which could increase conversions by up to 400%. This makes it a valuable resource for any online business. 

However, setting up A/B tests in WordPress can be challenging because of limitations with plugins and lack of built-in functionality. Having to rely on external tools outside of the platform can pose a different, but similarly limiting, challenge. 

But don’t let this prevent you from implementing this on your own website. A/B testing on WordPress is entirely possible with the right tools, and there are various plugins and platforms that make it easy to test conversion elements like CTAs and headlines without being fluent in code. In this article, we’ll take you through the advantages of A/B testing and look at several tools you can use to optimize your conversions. 

Why WordPress Sites Need A/B Testing 

For conversion-focused sites, A/B testing is an essential element. Whether you’re a service provider, an ecommerce store, or even simply a site that wants to build an email list or create high-performing funnels, split testing offers numerous advantages. 

• It helps to refine your site’s messaging, design, and CTAs to better engage and convert audiences, which is especially important in a crowded online space where more than 43% of all sites are powered by WordPress.
• A/B testing allows you to adapt your UX to new trends and shifts in consumer behavior.
• Better UX leads to lower bounce rates and longer sessions, which improves your site’s SEO and landing page conversion rates.
• With most traffic coming from mobile, it is important to test this aspect as well. Testing different layouts and elements ensures a more seamless and responsive experience across devices. 

Ultimately, A/B testing helps you get the most out of your traffic, thereby reducing acquisition costs and boosting your site’s revenue. 

“A/B testing transforms your existing website traffic into a learning laboratory, letting you systematically discover which changes actually work. Rather than relying on gut feelings, you can find the winning variations that help more visitors take meaningful actions – whether that’s making purchases, signing up, or engaging with content. By continuously optimizing based on real user behavior, you naturally improve conversion rates. This means you’re getting more value from every visitor without having to spend more on acquisition, effectively lowering your cost per conversion while increasing overall revenue.”

Comparing The 8 Best WordPress A/B Testing Solutions 

A/B testing can be beneficial for a variety of online sites, but you need to choose the right tool for your needs and budget. Below we’ve listed some of the top options for you, taking into account their different features and price points. 

1. FooConvert

FooConvert is the best plugin for increasing conversion rates on WordPress, and all of the data for your conversions is available directly within the WordPress dashboard. This means you don’t need to rely on server-side testing or external platforms like many of the other solutions in this list.

FooConvert is different to most of the other plugins listed below, in that it allows you to strategically place pre-designed popups, flyouts, and other action-triggered widgets anywhere on your site. These are designed to maximize conversions on your site, using pre-made templates and by targeting specific audiences with page-specific placement and activation triggers. 

The FooConvert PRO Analytics feature then gives you real-time data about how your conversion widgets are performing. This allows you to track conversions, make changes, and compare results in an iteration process, gradually increasing the effectiveness of your conversions based on how your site visitors respond to each widget. 

The statistics not only give you insight into the views, clicks, engagements and sentiment for your widgets, but also indicate when changes were made and what these changes were. For example, you can see if the widget was recently published, or if changes were made to the content. This allows you to assess which changes users responded to and if the changes resulted in improved interaction. 

Full A/B testing will be rolled out for FooConvert at a later stage, but you can still access limited statistics in the free version of FooConvert. Alternatively, install FooConvert PRO for more advanced conversion widget analytics. The FooConvert PRO plan starts at $39.99 per year and includes professionally-designed widgets and advanced analytics.

2. Optimizely

Optimizely is an AI-powered A/B testing platform that allows teams and site admins to carry out experiments with simultaneous different placements of important elements on their site. The platform offers several different products, including an entire CMS (Content Management System), but its web experimentation product allows for A/B testing in WordPress. This particular product allows you to collaborate on and design experiments for your website, which you can then implement and analyze.

Optimizely offers a range of features to help test and improve conversions. However, it likely requires some pre-existing developer knowledge and expertise to set up with WordPress since Optimizely runs variation experiments directly on your site’s server (unlike FooConvert, where all data is available within the WordPress dashboard). 

Optimizely pricing plans are personalized per business, so you would need to get in touch to request a quotation for your specific needs. 

3. Split Hero

Split Hero is a WordPress A/B testing tool tailored towards small businesses and agencies. The plugin allows you to set goals for conversions on pages, form-submissions, buttons, and WooCommerce products. Some of its unique features include the ability to schedule campaigns and create ‘guest’ Split Hero accounts to invite colleagues or clients to view campaigns (without necessarily being able to edit them). Agency users can also white-label Split Hero to pass on to their clients (enterprise option only). 

While Split Hero integrates with WordPress, its management interface operates independently, meaning you would need to log into the dashboard separately. For the basic plan Split Hero pricing starts at $29 per month (this gives you 1 active campaign), going up to $49 and $99 per month for 3 and 10 campaigns respectively. The Enterprise plan pricing is quoted by the Sales team.

4. Convert

Convert is similar to Optimizely, in that it runs on server-side testing. However, it does have a dedicated WordPress plugin to help WordPress sites carry out A/B testing with the Convert Experiences conversion optimization suite (for which you would need an account).

This platform offers several different testing options. However, as a solution, it is targeted more at large teams, organizations, and enterprises that want to roll out A/B testing at scale, with features such as split URL testing and multipage testing. 

Pricing begins at $299 for sites with 100 000 monthly visitors or less – this is only available at a monthly price. It increases up to $1495 per month for sites with 500 000 visitors.

5. Nelio A/B Testing

Nelio A/B Testing is a native WordPress A/B testing tool that allows users to easily test variations of pages and elements. It includes several unique features, such as heatmaps and click tracking, which give you a visual overview of exactly where site visitors are clicking on your pages. The plugin can also automatically roll out winning variations, to keep your site automatically updated with optimized element placement. 

While powerful, this plugin’s pricing may be higher than simpler alternatives, making it less ideal for budget-conscious or beginner users. Pricing starts at £31,45 per month for 5 000 monthly views (the Basic plan), rising to £95,95 per month for 50 000 monthly views (the Professional plan). Enterprise plans for sites with 200,000 to 1 million monthly visitors are priced between £289 and £831 per month.

6. WP Title Experiments

WP Title Experiments is a unique WordPress A/B testing tool, given that it exclusively tests variations of titles on your posts and pages. Each of the titles will be served randomly, and the plugin can then measure if people respond to the changes. The plugin claims to help you achieve better rankings on Google by increasing your CTR and, therefore, getting you more traffic. 

This plugin is specifically designed for A/B testing post and page titles within WordPress. It does not support split testing for other elements like content, images, layouts, or buttons, so if you’re looking for broader capabilities, you might want to consider one of the other options listed.

The tool is currently in the beta stage, so access is only available for users who register via the form on the sign-up page.

7. Thrive Optimize

Thrive Optimize is a simple A/B testing plugin for WordPress intended for non-technical users who want to optimize their landing pages. The plugin focuses on simplicity rather than having lots of different features, which can be good for smaller websites that want to optimize their conversion rates. 

It is billed as a “landing page optimization tool for non-techies” which could make it a good option for beginners. However, it only tests landing pages (built with Thrive Architect) and won’t test blog posts, headlines, buttons, or other on-page elements. 

This is an add-on to Thrive Architect, which is a page builder, or comes as part of the Thrive Suite. Thrive Architect and Thrive Optimize together cost $399 per year. Thrive Suite is the entire set of Thrive plugins and costs $599 per year. 

8. OptinMonster

OptinMonster is a popular suite of tools to help marketers increase leads, email signups, and sales, but it also allows for A/B testing within its platform. Split testing with OptinMonster is available for headlines, images, and other page elements, and provides real time analytics to help you make decisions on the fly. 

OptinMonster operates as a cloud-based platform, meaning you manage your campaigns through the OptinMonster website. However, it does provide a WordPress plugin that connects your site to its external dashboard, allowing you to embed and manage popups, forms, and other lead generation tools without leaving WordPress. The actual campaign creation and analytics, though, are handled outside of WordPress. An annual license costs $348 for the pro version. 

Get Started With WordPress Conversion Optimization Today 

If you’re just getting started with A/B testing, or unsure of what features you need to get started, you can begin by selecting a more budget-friendly A/B testing tool that works within WordPress, like FooConvert. 

This plugin is great for those who are starting with A/B testing. Although the plugin doesn’t (yet) allow for split testing variations of pages to different site visitors at the same time, it does allow users to make the changes manually, get data and iterate in real time. 

The plugin also has predesigned conversion elements, meaning you can start testing variations instantly – and you could even combine FooConvert with another A/B testing platform to test variations of FooConvert’s conversion elements. 

Regardless of the tools you use for A/B testing, it’s worthwhile documenting your testing process to build an optimization playbook for your specific audience and site to improve conversions going forward. Good luck!
