Game changer for CRO
by dblampied·5 months ago·1 reply

I added Nelio about a month ago. Our wordpress theme made install a bit complicated but Nelio support has been super communicative and helpful every step of the way. I am now able to run several detailed tests throughout my website each month and slowly chip away at getting a better and better conversion rate. Thanks Nelio!

Great A/B Testing Tool for WordPress
by chemusoide·9 months ago·1 reply

I’ve been testing the Nelio A/B Testing plugin and I’m very impressed with the experience.

  • The free version works great and lets you try all the main features with limited traffic — perfect to explore its potential and check compatibility with your site.
  • I also upgraded to the paid version, and activation was seamless — premium features were enabled instantly.
  • Support has been fast and effective whenever I had questions or needed help.

The plugin is easy to install and use, provides valuable insights, and is thoughtfully designed for running A/B tests, heatmaps, and user behavior tracking. I also checked site performance and found it has minimal impact compared to other similar tools.

In short: a powerful, easy-to-use solution for optimizing your website and understanding user behavior.

Great tool, amazing support!

David is very helpful and very fast with his replies. The tool works good and as intended. Easy to create A/B tests in WordPress with many different options and (multiple) goals. Amazing if you use it for wordpress with Hubspot forms as they work seamlessly together.

very helpful

The support team or the developer, who replied to our email, was very helpful. They answered quickly to our email asking for support. Also they were very solution oriented and helped us fix the problem unlike some other plugins that just says solve it yourself.
