Why use A/B testing?

Engage visitors

An exceptional user experience is central to engaging with your brand, convincing and retaining your visitors.


Understand your visitors

Deepen your knowledge of your visitors by testing and analyzing how different elements of your pages impact their behavior.


Make informed decisions, minimize risks

A/B testing your hypotheses eradicates risks, meaning you make decisions based on accurate data, rather than on subjective hunches.


Optimize time and budget

Concentrate your efforts (and your money) on what works best for all your audience thanks to A/B test analysis.

A dedicated multivariate testing tool

With Kameleoon’s multivariate testing (MVT) tool, you can simultaneously test all the possible combinations of different elements on the same page.


Target optimizations at the right people

With Kameleoon’s A/B testing solution, you can test elements with a specific part of your audience. 

Check your hypotheses with defined visitor segments, using 40 in-built criteria such as location, behavior, context or the type of pages they’ve viewed.


Manage your A/B tests

Kameleoon’s A/B testing solution offers a dedicated reporting tool including dashboards, providing multiple ways to visualize the results of your experiments.

It delivers clear recommendations that teams can immediately act on, continuously improving and optimizing your website UX: 

  • continuously analyze the results of A/B tests
  • access a detailed analysis of visitor behavior to obtain accurate, actionable insight
  • monitor and manage the performance of your tests in real-time. 

Full-stack A/B testing

Adopting a complementary approach to client-side testing

Kameleoon is a web and full-stack platform that enables you to carry out A/B testing on the client-side, the server-side and on mobile apps.

Server-side A/B testing means creating your conversion optimization hypotheses directly on your server. It’s a complementary approach to client-side testing technologies, allowing you to push your testing scenarios further.

Examples of types of test:

  • Implementing new business rules on the Product listing page: sorting by popularity vs sorting by price, product recommendation algorithms, etc.
  • Testing different price strategies in the purchase funnel: for example, offering free delivery above certain spend amounts
  • Gradually rolling out new key features to a targeted group of customers.

Compatible with your technological stack

Our server SDKs enable you to make modifications as the HTML pages are being generated. Our SDKs are available for the Java, .NET (C#), Node.js and PHP environments as well as for mobile platforms (iOS, Android and React Native). 

In an architecture where front-end web servers cache the web pages generated by the back-end, our Nginx or Apache httpd SDKs enable A/B tests to be created on these front-end web servers.

How does it work?

A simple if/else type-code in your back-end environment, coupled with calling methods from our SDK, lets you create two variations to distribute to your visitors. 

When you launch a server-side test, a unique request is sent from Kameleoon to your server, for the first visitor exposed to the test.

  1.  A first visitor targeted by your test arrives on your website

  2.  Your server sends a request to Kameleoon to download the configuration of the test settings (only for the first visitor exposed to the test).

  3.  The Kameleoon SDK attributes a variation to the visitor and the server generates the variation code.

  4.  The visitor sees the variation.

Full stack

Improve agility

With server-side testing, product teams and developers increase their agility and flexibility since it is possible to carry out in-depth tests of how well the website works.

Omnichannel strategy

In full-stack mode, you can deploy your A/B tests on all types of environment: web and mobile, including mobile applications. It is also possible to offer the same experience to a connected visitor, from one channel to another (website, app) and on all devices (mobile, desktop). You can therefore adopt an omnichannel approach by carrying out your experiments on all channels at the same time.

Increase performance and end flickering

With server-side testing, product teams and developers increase their agility and flexibility since it is possible to carry out in-depth tests of how well the website works.
