Web performance metrics and Google Core Web Vitals
Web performance optimization is increasingly critical for user experience and e-commerce conversion rates. Developers can utilize techniques such as link preloading, a declarative method to fetch assets via the HTML link tag, to improve page load speeds without affecting the onload event.
Google has integrated web usability into its search ranking through Page Experience updates and Core Web Vitals. These metrics evaluate how users perceive interactions with a page, focusing on factors like mobile-friendliness, HTTPS, and loading performance, specifically through metrics like Largest Contentful Paint (LCP).
To measure responsiveness, the experimental Interaction to Next Paint (INP) metric tracks the latency of all user interactions, including clicks, taps, and keystrokes. Unlike First Input Delay (FID) or Total Blocking Time (TBT), which only capture subsets of interaction data, INP provides a holistic view of a site's responsiveness throughout a page visit.
