    We will never be tired of repeatedly repeating that WordPress is the world’s leading CMS that powers more than 39.5% of all websites available online. If your site is also running on WordPress and you look for ways to improve conversion rates on it, WordPress A/B testing will help you improve user experience and grow the key metrics of your site. One of the best things about this approach is that it lets you run as many tests on as many elements as you need to watch the desired boost in statistics.   

    In this article, we will discuss what you can test on your site and what tools will help you reach the best results for your business. 

    How Can You Benefit from WordPress A/B testing

    Before we dig into details on where you can apply A/B testing and what plugins prove to be the most effective for this purpose, let’s discuss how the concept works and what benefits you can derive from using it. 

    A/B testing is also known as split (or bucket) TESTING. It’s an online marketing tactic that lets you compare how different versions of the same product or website element work to see which option your customers prefer most of all. In terms of WordPress, it’s the approach of comparing different elements of a web page. It includes the comparison of color schemes, content, headers, widgets, page layouts. CTAs, titles, etc. WordPress A/B testing can bring many benefits to your business, like the following ones: 

    Better ROI on Your Site’s Traffic 

    The traffic that you drive to your site mainly depends on your marketing efforts and the strategy you follow. While running A/B testing on your website, you can find what particular elements of your web page should be optimized, in what ways you can do it, and what optimization opportunities let you deliver better UX on your site. Even some minor tweaks on your site can bring impressive results. As a result, you can get improved conversion rates and better ROI on your site.   

    Make Wise Decisions on the UX Improvement 

    Many applications let us measure user experience on our websites. However, it may be tough to predict what might be causing your site’s troubles and result in poor conversions and worse user experience. Even if you feel certain about your decision regarding the changes that should be done on your site based on the results of your research, you need to check if your hypothesis is absolutely right. That’s when WordPress A/B testing comes into play. 

    Based on the insights you gather after using Heatmaps. Website Analytics, Surveys, and other tools, you can validate them using A/B testing. By doing so, you may feel certain that every change you make on your site will be positively reflected by your audience and result in higher conversion metrics. 

    Reduce the Risk of Doing Wrong Changes 

    If the research reveals that your website is outdated and needs significant changes, you need to make sure that you do everything right. A major update of your site’s design could go either way. It could hit the right points and fix the major issues, thus attracting more visitors and engaging them more effectively. At the same time, people may not be ready for drastic changes on your site, so building a new element on top of the previous one is a surefire method of creating an evolutionary redesign. By doing so, you can avoid making any radical changes and get your audience ready for the entire web design to revamp before you are completely sure of it and its effect on your audience. 

    Standing Out Among Competition

    Every business strives to stand out from competitors and appeal to the target users’ minds. A website is your business card and a reflection of your brand. It should be a clear demonstration of your ideology, goals, values, and offers. It should encourage the audience to take the desired actions. While running A/B tests on your site, you can keep your audience at the forefront of your optimization efforts and provide them with the web resource that meets their expectations, thus keeping your business ahead of the curve.  

    What Can You Test on Your WordPress Site? 

    You can apply WordPress A/B testing to every element of your site. Let’s consider the most popular examples. 

    Headlines on Your Site 

    There are plenty of rules and recommendations on how to write headlines. However, you never know what works best for you until you test it. The A/B testing will work for the headlines on different pages of your site and blog posts. When you compare statistics sometime after the headlines’ update, you can see which headlines drive more traffic to your posts and which of them help you drive better conversions. 

    Online Forms

    Contact forms are vital elements that let you establish better communication with your audience. A well-designed and well-organized contact form has a direct impact on the conversion metrics of your site. Although many contact form builders are available on the web, it may be challenging to decide on the best solution that will appeal to your audience. What works best for one business may not work for another one. Using A/B testing, you can run experiments on your site and find the optimal form fields, form length, form placement, and other aspects that will help you get better results on your site.

    The conversion metrics and user engagement stats depend on how call-to-action buttons are designed and where they are located on your site. The size, color, shape, and placement are crucial factors that drive maximum conversion. Choose the perfect combination for your site with the A/B testing.


    The content that you add to your website should be persuasive, impactful, and valuable to your target audience. As a rule, it takes some time until you come up with the perfect content strategy that perfectly resonates with your customers. It requires time and testing until you find out what appeals to your readers the most. Whether you are building a website from scratch or working on the rebranding of the existing web page, you need to run some methodological testing until you finalize the content version that would increase conversion rates on your site. 

    Website Menu

    Your website’s menu layout and navigation patterns play a major role in directing your customers to important pages. To facilitate your site navigation, take care of testing different menu layouts to develop the one that will drive users to browse your site and take the desired actions seamlessly.

    Widgets are the essential component of any website. You may run a personal blog or a large corporate website. With the right choice of size, copy, placement, and design of widgets, you can significantly influence the conversion numbers on your website. While running A/B testing, you can experiment with different widget variations on your website to ensure that you pick the solution that will fulfill your site’s right purpose.

    Images speak louder than words. While supplementing texts with images, you can increase the retention rate for your content to 65%. For comparison: text-only content features an average retention rate of about 10%. That’s why testing your site’s visual content in combination with different pieces of content is vital to optimizing your pages for better performance.

    WordPress Themes

    Recently, it’s become trendy to build websites with ready-made themes instead of working on custom-made solutions.
