Server-Side A/B Testing is a method of conducting website optimization experiments in which the experiment is executed on the server-side. This means that the changes made to the website are made directly on the server, rather than on the client-side. The server then serves different versions of the website to different users based on a set of predetermined criteria.
The goal of server-side A/B testing is to measure the impact of changes on the website’s performance and user experience without compromising the integrity of the website or affecting the user experience for other visitors.
This method is often preferred for complex or high-traffic websites where client-side testing may not be feasible or reliable.
