Core Web Vitals Optimization
Core Web Vitals adalah ranking factor resmi Google sejak 2021:
- LCP (Largest Contentful Paint): < 2.5 detik
- FID (First Input Delay): < 100ms
- CLS (Cumulative Layout Shift): < 0.1
- INP (Interaction to Next Paint): < 200ms (menggantikan FID)
// Measuring Core Web Vitals
import { getCLS, getFID, getFCP, getLCP, getTTFB } from 'web-vitals';
getCLS(console.log);
getFID(console.log);
getFCP(console.log);
getLCP(console.log);
getTTFB(console.log);
// Optimize LCP
