Top 5 WordPress AB Testing Plugins

If you’ve been in the Internet marketing scene for any amount of time, you’ve probably already heard it ad naseum:

AB test everything to optimize your sites.

And while it’s repeated so often it starts to almost sound cliché, they’re absolutely right.

However, with so many options out there (with some of them being integrated into larger plugins), it can be difficult to decide which plugins for WordPress AB testing to look into and which ones aren’t worth your time.

So in this article we’ll lay out the 5 Best WordPress AB Testing Plugins to use on your site. They vary in their interface and features but all provide robust and powerful data that you can use to improve your site’s performance.


1. Google Content Experiments

This used to be its own individual tool called Google Website Optimizer, but now goes by Google Content Experiments and is implemented directly into Google Analytics. That’s partly what makes it so appealing—if you already have Google Analytics tracking your website, you can already get to work and start A/B testing. Additionally, as it takes data directly from Google, it gives you very accurate information.

A downside of Google Content Experiments is that it doesn’t have some of the more insightful features that a lot of the paid options for WordPress split testing have. For example, it has somewhat clunky user interface and it doesn’t allow for multivariate testing (you can only test two components at a given time, rather than multiple elements). On the upside, it’s completely free.

  • Main Features: test up to 10 variations of a landing page, choose various objectives you’d like to test on your site, you can determine what number of your site’s users will be included in the experiment, and you can compare the performance of app screens or web pages by taking a random sampling of your audience. On top of all that, you can get email alerts about your campaign results.
  • Price: Free

2. Optimizely

Optimizely is the go-to WordPress AB testing plugin for some of the biggest websites in the world, and for good reason. It’s extremely powerful and gives you a wealth of data so that you have all the information you could possibly need to interpret your testing results.

Considering all the power that comes with this plugin, it does help to have some technical know-how in regards to coding, so if coding is not your thing it may be wise to go with another choice.


Optimizely doesn’t post their pricing online. To find out, you can call them at 1-800-252-9480 or contact their sales department from
