Google is adding Core Web Vitals to its Page Experience ranking signal, which evaluates speed, responsiveness, and visual stability of pages. This means that website performance has a direct impact on SEO and business. The three main components of Core Web Vitals are Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). A good LCP is below 2.5 seconds, an FID score below 100ms, and a CLS metric below 0.1. Improving website performance can help sites rank higher in comparison to competitors. Strategies for improving Core Web Vitals include pre-rendering content, image optimization, font optimization, and using server-side rendering or Next.js pre-renders every page by default. Google Lighthouse and Vercel Analytics are tools that can be used to measure and analyze Core Web Vitals performance.
