Experimentation

https://www.aem.live/docs/experimentation

Experimentation is the practice of making your site more effective by changing content or functionality, comparing the results with the prior version, and picking the improvements that have measurable effect.

For sites running on Adobe Experience Manager, there is the experimentation plugin that allows developers to add an experimentation capability to their sites. Three things make this approach different:

• It’s easy to set up tests in the tools your authors are already familiar with, no separate login is needed
• It’s deeply integrated into the AEM delivery system, does not slow down your site and is resilient to changes in code and content
• It allows testing simple content changes as well as experiments covering design, functionality, and code
