Website Speed Optimization: Ultimate Guide

## Why Website Speed Matters

Website speed directly impacts user experience, SEO rankings, and conversion rates. Even small speed issues can hurt user experience, search visibility, and conversion potential.

Core Web Vitals

Google's Core Web Vitals measure user experience: - **Largest Contentful Paint (LCP)**: Should be under 2.5 seconds - **First Input Delay (FID)**: Should be under 100ms - **Cumulative Layout Shift (CLS)**: Should be under 0.1

Essential Speed Optimization Techniques

### 1. Choose Fast Web Hosting Your hosting provider is the foundation of speed: - NVMe SSD storage (4x faster than SATA) - LiteSpeed web server - Global CDN integration

### 2. Optimize Images Images often cause the biggest slowdowns: - Use WebP format (30% smaller than JPEG) - Enable lazy loading - Compress images before uploading
