The Website Speed Playbook: 16 Reasons Websites Quietly Get Slow

I audit websites for a living. Then I found my own site was taking 55.8 seconds to load.

This playbook is built directly from that real audit — 16 reasons websites quietly become slow, how to correctly diagnose the actual bottleneck, how to fix issues without creating new ones, and how to keep a site fast long-term.

Includes the exact mistakes I made and fixed on my own site, including one that briefly broke my own images while trying to fix them.

Each problem includes what it is, why it matters, how to diagnose it, and a step-by-step fix.
