Why Core Web Vitals?
Core Web Vitals are the essential metrics that search engines like Google use to measure how "good" a user's experience is on your page. Fast loads and stable layouts aren't just for SEO; they prevent user frustration and drop-offs.
Understanding Metrics
- LCP (Largest Contentful Paint): Measures loading performance. Aim for < 2.5s.
- FID (First Input Delay): Measures interactivity. Aim for < 100ms.
- CLS (Cumulative Layout Shift): Measures visual stability. Aim for < 0.1.
