This podcast episode explores the concept of Core Web Vitals, a set of metrics designed to measure the user-centric performance of web pages. These metrics encompass loading performance, interaction responsiveness, and layout stability, providing a comprehensive view of the user experience. The episode introduces a new metric, Interaction to Next Paint (INP), which offers a more accurate measure of interactivity than previous metrics like First Input Delay (FID). Experts discuss the importance of integrating Core Web Vitals into daily workflows and the collaborative effort required from site owners, framework developers, and browser vendors to improve web performance.
