Reasons for choosing Nelio

Take a look at the following reasons for choosing Nelio A/B Testing!

#1 - Native A/B Testing Solution for WordPress

There's no need to learn an external tool. Define, manage, and track the progress of your experiments directly from within WordPress. Nelio A/B Testing provides a lovely and well-known user interface that simplifies the process of creating alternatives and applying the winning ones.

#2 - Create Alternative Content for your Pages, Posts, and Custom Post Types

When creating A/B experiments, the first things you'll want to test are the pages of your website. Does this button work? Do my visitors go from the landing page to my pricing page? What if I change this background image? Nelio A/B Testing makes page (and post) experiments super easy!

Moreover, version 4.1 includes support for custom post types. Use Nelio A/B Testing with any plugin that defines its own custom post types (such as Products, Videos, Reviews, and more).

#3 - Go beyond simple title tests—Test Headlines!

Are you a Publisher? Are you an avid blogger? Then, you probably want to deliver to every reader a more engaging and relevant reading experience. Nelio A/B Testing includes is the first A/B testing tool for WordPress that offers Headline Experiments. Given a post in your site, create alternative titles, excerpts, and featured images, and discover which combination gets more visitors to click the link and further read the post from anywhere in your site!

#4 - Test Widgets

Nelio A/B Testing is the only solution that includes Menu and Widget Testing. Use the WordPress' default user interface for creating new menus and widget sets. You'll be able to duplicate your current menus and widgets, and modify them with just a few clicks. Discover which combination improves your conversion rate!

#5 - Beautiful Heatmaps and Click-maps

Heatmaps (and Click-maps) offer valuable information about what your visitors do and don't do when they land to your website. Also, they are a perfect companion of A/B experiments, for they give insights on what to text next and help you understand the progress of your experiments.

#6 - Test Alternative Themes and CSS

If you're planning to change your theme, or tweak its CSS rules, make sure they'll benefit your business. Nelio A/B Testing makes theme and CSS testing extremely easy! Simply select the themes you want to test (or define the alternative CSS rules you want to apply), and the plugin will take care of the rest.

#7 - Conversion Actions and Evolution of Your Experiments

With Nelio A/B Testing, you can track the important actions your visitors take. Don't get lost with tons of irrelevant options and data. Focus on what matters. Our plugin will offer you fresh information about the evolution of the experiment, with nice graphics about visitors and conversions.

#8 - Cache Support and Server Load

One of our priorities is efficiency. The process of A/B testing a site is not necessarily at odds with performance. Nelio A/B Testing implements several mechanisms to reduce the impact of testing your site, such as a Performance Must-Use Plugin (that reduces response times of any AJAX request triggered by Nelio), support for cache systems in WordPress, and optional site-wide consistency (if you're testing a page or post, not only that page or post has to change, but also any page that includes a widget referencing it).

#9 - Outstanding Support

We work very hard to offer an amazing support to all our customers. If you encounter compatibility issues or you have problems setting the plugin up and running, contact us and we'll do our best to help you!

#10 - Subscription Plans that Fit Your Needs

Nelio A/B Testing aims to offer a complete A/B testing experience for everybody. That's why you can create an unlimited number of experiments of any kind subscribing to any of our packages. Just check our subscription plans and select the one that better suits your needs.

4.6.0 (February 8, 2016)

  • Improvements. Post conversion actions now searches among custom post types too.
  • Test. Tested with WordPress 4.7.

4.5.11 (December 29, 2016)

  • Improvements. The plugin is now compatible with domain mapper.

4.5.10 (December 4, 2016)

  • Bug Fix. URLs including an empty page fragment (just the symbol #) can now be properly tested.
  • Bug Fix. Some click events stopped heatmap tracking unnecessarily.
  • Bug Fix. SSRF vulnerability located in ajax/iesupport.php has been fixed.

4.5.8 (October 5, 2016)

  • Improved Results. Results are now cached more frequently in your WordPress server, so that they're available right when you need them.
  • Improvement. Added a safe guard in the Heatmaps processor that makes the plugin resilient to JavaScript errors generated by the theme or other plugins.
  • Bug Fix. There were some issues synchronizing your running experiments with Nelio's cloud. This has been fixed in this version by adding some extra checks in the synchronization process.

4.5.7 (September 21, 2016)

  • Bug Fix. Invalid argument in a foreach statement (in visitor.php) is now fixed.

4.5.6 (August 16, 2016)

  • Bug Fix. WooCommerce order complete actions weren't properly tracked, because of invalid experiment IDs were used. This has now been fixed.

4.5.5 (July 22, 2016)

  • Bug Fix. Form submissions were not properly synched. Now they are.

4.5.4 (July 14, 2016)

  • Compat Improvement. Some themes weren't compatible with Nelio because some filters were triggered before the setup_theme action. This has now been fixed.
  • Bug Fix. Some click events (for instance, when tracking an element whose ID includes a : char) couldn't be tracked because they generated a JavaScript exception. This is now surrounded in a try-catch block.

  • Improvement. nabforce now overwrites both the alternative version the user is supposed to see and the user's participation in the experiment.
  • Bug fix. Renamed AJAX parameter from filename to classfi so that security plugins (such as Wordfence) do not block Nelio's requests.

4.5.1 (April 29, 2016)

  • Bug fix. Invalid continue statement changed to return.
  • Bug fix. Some query args were not properly encoded, resulting in an invalid query string. This has been fixed.

4.5.0 (April 8, 2016)

  • Security Fix. This new version fixes a couple of security issues we detected. In particular, we improved input sanitization and we limited file access to those within the plugin's path.
  • Bug Fix. In the Results page of a post/page experiment, there are two options for previewing an alternative: clicking on a button or on a preview image. The former works, the latter doesn't. This has been fixed.
  • Minor improvements.

The full change log can be found in changelog.txt.

Why should I use an A/B Testing Solution specifically designed for WordPress?

  • Smooth learning curve. There is no need to learn yet another tool. Everything (from the creation of tests to the visualization of the results) is done from the WordPress dashboard you are familiar with, resulting in a well-known, perfectly integrated user interface.
  • Evolve your WordPress site easily. A native WordPress solution automates and simplifies the evolution of your site. Consider, for example, applying the winner alternative in your site as soon as the results are statistically significant. With a native solution, this is as easy as clicking one single button. With a generic tool, on the other hand, you would have to manually modify the page so that it integrates the changes you created in the (winning) alternative.
  • Fine-grained testing. The "testing unit" in a generic tool is the web page, since the HTML of the page is the only thing those tools have access to. A native WordPress solution, however, permits you to test any WordPress specific component, such as posts, pages, CSS, themes, child themes, and many more coming!
