Comparing two versions of a web page in A/B testing primarily helps to determine which version performs better in user engagement. This testing method involves presenting two variants of a webpage to different segments of users and analyzing how each version influences specific user behaviors, such as click-through rates, conversions, or overall interaction time on the page. By analyzing these metrics, it becomes possible to identify which version resonates more with the audience, leading to improved user experience and potential increases in effectiveness for the website's goals.

While factors like bandwidth consumption, visual appeal, and coding efficiency may be important in web development, A/B testing is specifically designed to assess variables that affect user engagement and behavior. Therefore, the focus is on understanding how users interact with each version of the webpage rather than technical performance or aesthetic preference alone.
