Passionate about UX? Pay attention to web performance metrics
Blog post from New Relic
User experience (UX) is significantly influenced by performance, as even the most innovative designs can fail if a site is slow or prone to errors. Developers play a crucial role in shaping UX by optimizing application performance, which can be measured beyond basic health metrics by focusing on user-centric indicators like Google's Core Web Vitals. These metrics, such as Largest Contentful Paint (LCP), are crucial for understanding how performance affects user engagement, particularly when analyzed across different devices and parts of the user journey. For instance, slow LCP on mobile devices can lead to user frustration, even if desktop performance appears adequate. By partitioning data based on device, region, and specific user journey stages, businesses can identify and address performance bottlenecks that might not be visible in average metrics. This approach helps improve the digital customer experience, as outlined in New Relic's guidelines, which emphasize the importance of focusing on user experience metrics to enhance site performance and user satisfaction.
