Looking for the best WordPress A/B split test plugin or tool to grow your form submissions?

By split testing your forms, you can understand what works best with your audience, and optimize your forms for more leads.

In this article, we’ll share the ten best WordPress A/B testing plugins and tools for your forms.

Why A/B Test Your WordPress Forms?

A/B testing (also called split testing) allows you to compare two or more versions of your WordPress forms or other page elements to see which one performs better.

In an A/B test, you can show multiple versions of your form to similar visitors at the same time by varying different form elements such as headlines, images, call to action buttons, copy, fields, etc. You can then compare conversion rates of your variations, and the one that gives a better conversion rate wins.

The main benefit of running an A/B test is that you don’t have to make a blind guess on what works best and which form elements bring in more conversions.

Instead, you can make data driven decisions to boost your form submissions.

How to Enable WordPress A/B Testing

With the right A/B testing plugin or tool, you’ll be able to duplicate your WordPress form with a single click and make necessary changes by varying different form elements on it.
