Step-by-Step Guides to Building and Growing Your Website
Website Performance covers the technical changes that affect how fast a site loads — caching, image optimisation, a CDN, and fixing Core Web Vitals like layout shift.
Most performance problems aren’t obscure, they’re the predictable result of skipping a handful of well-understood configuration steps. These articles focus on changes that make a genuine difference without needing server administration skills.
Toggling the DevTools device toolbar changes the viewport, not the CPU or network. Here’s the real gap between simulated throttling, calibrated throttling, and an actual phone on an actual connection — and why INP is the metric that exposes it.
A clean plugin list and a caching plugin aren’t enough if third-party scripts are still the real Total Blocking Time problem. How to actually find, audit, and decide what to cut, delay, or keep.

TTFB (Time to First Byte) is the server response time metric in Google PageSpeed Insights and Core Web Vitals. Learn how to reduce TTFB in WordPress using caching, database optimisation, CDN, and PHP upgrades.
A caching plugin serves a saved copy of each page instead of rebuilding it from scratch — which one to pick, backed by real install numbers, and how to tell page caching apart from the other kinds.
