Perché usare uno strumento di A/B Testing ideato specificamente per WordPress?
  • Curva di apprendimento agevole. Non c’è bisogno di imparare a usare un nuovo strumento. Puoi gestire tutto (dalla creazione dei test alla visualizzazione dei risultati) tramite la bacheca WordPress di sempre: un’interfaccia utente conosciuta e perfettamente integrata.
  • Fa evolvere con facilità il tuo sito WordPress. Una soluzione nata per WordPress automatizza e semplifica l’evoluzione del tuo sito. Considera, per esempio, che puoi applicare l’alternativa migliore per il tuo sito non appena ottieni dei risultati statisticamente significativi. Con una soluzione nativa, lo puoi fare con un solo clic. Con uno strumento generico, invece, dovresti modificare manualmente la pagina in modo da integrare le modifiche appartenenti all’alternativa vincente.
  • 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!

Este es, de largo, el mejor plugin de test a/b para WordPress a día de hoy. No solamente ofrece una herramienta completa si no que dispone de extras como los mapas de calor, de clics y de confetti que aportan un valor enorme y que no están disponibles en otras plataformas como por ejemplo Google optimize. Bravo por el equipo de Nelio.

I have 2 relatively small sites and it was suggested to me by Dom Wells at HPD that I try A/B testing now that I've got sufficient traffic. I'm a beginner with A/B testing and found Nelio. I have to say I'm glad I did. (Side note: Nelio allows you to use 2 of the $29 plans if the more expensive plan is a bit much for you.) I learned some interesting things, and found out some of the changes I made actually LOWERED my click through rates, rather than improving them! That kind of data is excellent. Data is displayed well, and making an alternate test page was much easier than I expected. For small changes you can have a test running in below 1 minute. I've had some technical issues pop up (as often happens with WordPress) and support has been great. Someone wrote: "Other a/b testing software have more features (like user recording sessions) and costs the same or less, but they’re not native to WordPress, so I feel like I’d have to re-create the design in my WordPress site if it performed better to make it match my theme." I don't agree at all. From what I saw, most services are more expensive. (I have no idea that that 2nd sentence was for also, as that's not really the case regardless.) Overall a very good testing plugin with great support and it's affordable. Thanks!

This is the only native wordpress A/B testing software that I know of that also tests navigation. That being said, there's a bug in the program that doesn't allow me to test my navigation. I've contacted support but I get 24-48 hours lag in response. There was another bug a week ago that wouldn't allow me to see my other goals. Other a/b testing software have more features (like user recording sessions) and costs the same or less, but they're not native to WordPress, so I feel like I'd have to re-create the design in my WordPress site if it performed better to make it match my theme. Also, I don't know how you'd test navigation elements. Still searching for A/B testing software out there that might perform better than this one.
