Optimizing Web Performance in 2026

Web performance is a critical factor for both user retention and SEO ranking. In 2026, users expect sites to be interactive in less than a second. ### Key Metrics to Monitor - **LCP (Largest Contentful Paint)**: Measures loading performance. - **INP (Interaction to Next Paint)**: Measures responsiveness. - **CLS (Cumulative Layout Shift)**: Measures visual stability. ### Optimization Checklist 1. **Format Images**: Use next-gen formats like AVIF or WebP through Next.js `<Image />` component. 2. **Code Splitting**: Dynamic imports in Next.js help load code only when it's needed. 3. **Edge Caching**: Utilize CDNs and Edge Functions to serve content closer to your users. 4. **Font Optimization**: Use variable fonts and self-host them to avoid external latency.
