Web Vitals is a Google initiative that provides unified guidance and essential quality signals for delivering a great user experience on the web. It focuses on Core Web Vitals, which measure loading, interactivity, and visual stability through specific metrics like Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. Site owners should aim to meet recommended thresholds for these metrics at the 75th percentile of page loads across mobile and desktop devices.
