A/B testing is a great way to optimize your website for conversion. No matter how great your website is, you can’t afford to sit around and not test your design to optimize it for better conversion rates. By doing split testing, you can identify the pages and offers that work the best for your business. Max A/B is a free WordPress plugin that lets you do more testing and spend less time worrying about code.
Creating new experiments using this plugin is pretty easy. It supports your original page as well as three variations of your pages. The conversion page can be on your main website or any other domain. You are in control of when your experiments end. If you choose the manual way, your experiments continue until you have enough data to stop and make decisions.
