Website Speed: Complete Optimization Guide
Page speed affects both rankings and user experience. A slow site loses visitors, conversions, and credibility. Here's how to make it fast.
The biggest speed killers
Oversized images: The #1 cause of slow pages. Compress, use WebP, and serve responsive sizes.
Too many plugins: Each adds JavaScript. Audit and remove unused ones.
Slow hosting: Cheap shared hosting often has slow server response times.
Render-blocking resources: CSS and JS that delay page display.
No caching: Every visitor downloads everything fresh.
