Web Vitals

ELI5 — The Vibe Check

Web Vitals are Google's report card for how good your website feels to use. They measure things like 'how fast does the main content load?', 'does the page randomly jump around?', and 'how quickly does it respond when I click?' Bad scores = unhappy users and lower Google rankings.

Real Talk

Web Vitals is a Google initiative that provides a set of quality signals essential to delivering a great user experience. The Core Web Vitals subset (LCP, CLS, INP) are direct Google ranking factors. They are measurable via the web-vitals library, Chrome DevTools, Lighthouse, and Google Search Console.

import { getLCP, getCLS, getINP } from 'web-vitals'

getLCP(metric => console.log('LCP:', metric.value))
