Nelio A/B offers “split testing as a service” all the data collection and processing is done on our backend servers to avoid any performance penalty on your WordPress installation. In order to use our service, you just need to install a plugin on your WordPress site. Instead of relying on subjective opinions, the algorithms behind Nelio A/B Testing monitor the behavior of your visitors and automatically tell you which variant of the tested element (for example, your landing page, a post or the theme you use) converts better. You simply create two or more versions of the element you want to optimize and then Nelio takes care of randomly showing the different versions to your visitors to determine the winning alternative.
