Top 5 A/B Testing Plugins for WordPress

As WordPress website owner you should know the most popular AB testing plugins for your WordPress websites. Making a simple WordPress website does not take so much time and resources anymore. You can just spend a few bucks on hosting, download free or cheap template, add some content and you’re done.

Nevertheless, usually the result you get won’t be considered a “good” website. You’ll want to add new features and change existing ones. But would you know what to change and how to do it? That’s when A/B testing comes into play.

Is there a sense in having thousands of users if they don’t convert? Not much. That’s why most businesses spend a pretty penny on conversion optimization.

WordPress AB Testing Plugins

According to Optimizely “A/B testing is a method of comparing two versions of a webpage or an app against each other to determine which one performs better. AB testing uses data & statistics to validate new design changes and improve your conversion rates.

Before starting the A/B testing you should decide upon an objective (what is the main goal of your business). Then, choose KPI to evaluate the performance. After that you should decide what elements and variations you want to test.

With today’s A/B testing software almost every element of a website can be tested: Sign-up forms, Call-to-actions, Site search, Images, Navigation, Checkout process, Site colors, Headlines, General copy, Page layout, Prices, etc.

If you already know what and how you want to test, it’s time to pick the right A/B software for your WordPress website.
