Why Page Speed & TTFB Matter for SEO Rankings

Website speed is a direct Google ranking factor under Page Experience signals. Key Speed Optimization Pillars: 1. Server TTFB: Ensure server response time stays under 200ms by utilizing fast hosting, edge caching, or CDN networks. 2. Lightweight DOM: Keep DOM tree size under 1,500 nodes to prevent memory bottlenecks during page rendering. 3. Image Compression: Compress heavy images to WebP/AVIF format to reduce page weight.
