Diagnosing a slow business website
01

Why should you measure before you guess?

Use real-device testing and field data, not just lab scores. Slow TTFB often points to hosting or server-side work; slow LCP usually means oversized hero images or render-blocking assets on the front end.

02

What are the common fixes for a slow website?

Serve modern image formats, lazy-load below-the-fold media, and strip unused plugins or scripts. Put static assets behind a CDN, enable compression, and make sure TLS and HTTP/2 or HTTP/3 are configured correctly.

03

When should you rebuild the website?

Page builders and bloated themes hit a ceiling. If every tweak fights the platform, a clean rebuild on a modern framework often delivers faster loads, better security and lower long-term maintenance.
