The Ultimate Guide to Optimising for Core Web Vitals
What Are Core Web Vitals? Core Web Vitals are a set of metrics designed by Google to assess a site’s user experience through three primary areas: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These metrics analyze how quickly a site loads, responds, and maintains visual stability. Largest Contentful Paint (LCP) measures loading time for the largest visible element on a page, aiming for 2.5 seconds or faster for a smooth user experience. First Input Delay (FID) tracks how quickly the site responds to a user’s initial interaction, with an ideal FID under 100 milliseconds. Cumulative Layout Shift (CLS) measures visual stability to prevent unexpected content shifts, with a score below 0.1 indicating minimal disruption to the user. Each of these metrics provides insights into areas that can enhance user experience and engagement, making Core Web Vitals essential for improving site performance.
