Define "Web Performance Optimization (WPO)."

Web Performance Optimization (WPO) refers specifically to techniques and strategies employed to enhance the speed and efficiency of web applications. The focus of WPO is on improving the loading times of pages, minimizing latency, and addressing various factors that can negatively impact performance. This involves optimizing images, reducing the size of scripts and stylesheets, implementing caching strategies, and using content delivery networks (CDNs) to ensure that users receive data as quickly as possible.

Speed is a critical factor in user experience; slower applications can lead to higher bounce rates and reduced user engagement. By prioritizing the techniques for increasing web application speed, WPO directly addresses the goals of enhancing user satisfaction and operational effectiveness on the web.

Other choices, while related to web performance in some aspects, do not encapsulate the full scope of what WPO specifically aims to achieve. For instance, monitoring web traffic primarily focuses on analyzing users' interactions with a website rather than enhancing performance. Strategies for increasing app reliability concentrate on maintaining consistent service rather than simply improving speed. Methods for optimizing user interfaces deal more with design and usability than with performance metrics.
