With digital marketing, knowing what works and what doesn't is crucial as you make decisions with the goal of generating revenue. However, it can be difficult to isolate "what works" when there are so many variables. That's where A/B split testing comes in.
An A/B test, or split test, is an experiment you can run to isolate one variable. The idea is that you pit one version of the variable against another (with all other elements remaining the same) and measure and analyze the performance of each.
This can help you make data-driven decisions on messaging, aesthetics, and more. You can easily perform these tests on a WordPress site with the help of some tools.

Nelio A/B Testing negates the need for an external tool, offering a whole suite of split testing features natively in the back end of your WordPress site. With heatmaps, conversion action tracking, and even title testing, you can experiment with nearly all the elements of your site.
Google Optimize is without a doubt one of the strongest A/B testing tools on the market. It allows you to play with a variety of elements on your site in a number of ways, including A/B, multivariate, and redirect tests. It also integrates with other Google products (such as Google Analytics) for a seamless experience.
The only downside is that it doesn't have a WordPress plugin. However, with the Google Optimize add-on for MonsterInsights, you can easily implement it on your site and benefit from all it has to offer.
OptinMonster is known for being a lead generation plugin that offers lightbox popups and other opt-in forms. However, OptinMonster also comes with A/B testing for those critical conversion elements on your site. This is in addition to their robust behavior-based personalization features that can help you as you improve conversions on your site.
VWO is a powerful A/B testing platform that features a visual editor for you to make changes and set up variations without writing code. It also has advanced analytics capabilities and will make recommendations based on statistical significance. In addition, you can keep track of your hypotheses and their results. This software connects to WordPress with a convenient plugin.
Similar to OptinMonster, Icegram's value lies in its powerful conversion tools. You can implement popups, action bars, and more to aid your lead generation efforts and create powerful UX experiences.
However, Icegram knows the importance of testing in CRO and offers split testing for their features. You'll be able to experiment with opt-ins, headlines, CTAs, button colors, and more — the results of which can inform your strategy as you use Icegram to create even better opt-ins.
There's no need to create an account with a third-party A/B testing with this plugin. It allows you to run split tests natively in the visual editor. All you have to do is create a block of content where you designate variants and can switch between them as you add messaging and visuals.
It provides the statistical significance of each test, and you can make the winning variant permanent with just one click.
SplitWit is an A/B testing software that uses machine learning and AI to provide you with better data-driven insights. First, you create a SplitWit account and then tie your WordPress site to it with the SplitWit plugin. From there, you can manage the project on their platform and take advantage of the visual editor.
This plugin also uses advanced AI to help with conversion optimization. What makes it unique is that it can test multiple variables at the same time, showing different combinations of elements until there's a clear, statistically significant winner for the page. This makes it a great option for marketers who need a set-it-and-forget-it solution where the machine does all the work.
It's important for your business to know what your users are looking for, what's resonating with them, and what's not so that you can generate leads and revenue effectively. Once you're equipped with the right A/B testing plugins, you can begin making informed decisions for growth.
