Search Engine Optimization (SEO) is no longer just about keywords. Google now prioritizes user experience through "Core Web Vitals".
Key Metrics
1.
**Largest Contentful Paint (LCP):** Measures loading performance. Aim for 2.5s or less.
2.
**First Input Delay (FID):** Measures interactivity. Aim for 100ms or less.
3.
**Cumulative Layout Shift (CLS):** Measures visual stability. Aim for 0.1 or less.
In our projects, we utilize Next.js's built-in image optimization and server-side rendering to ensure these metrics are always in the green.
