What is the primary goal of A/B testing in UX design?

The primary goal of A/B testing in UX design is to compare user engagement between different design versions. A/B testing involves presenting two variations of a webpage or application to users to see which version performs better based on specific metrics, such as click-through rates, conversion rates, or other key performance indicators. This methodology allows designers and researchers to make data-driven decisions to improve user experience by identifying which design elements resonate more effectively with the target audience.

By focusing on user engagement, A/B testing provides insight into how real users interact with different designs, helping to refine and optimize user interfaces. This approach leads to better user satisfaction and can significantly impact key business objectives, making it a crucial aspect of the UX design process.

The other options, while relevant to other areas of UX and design, do not accurately represent the primary goal of A/B testing. Identifying user complaints, enhancing code efficiency, and creating documentation serve different functions within the UX process but are not the focus of A/B testing.
