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.
“Eliminate render-blocking resources” has a straightforward fix — defer JavaScript, inline critical CSS — and a widely-used plugin (800,000+ installs) that handles both without touching theme code.
Before installing a minification plugin, check whether your theme already ships minified assets — then, if it doesn’t, how to add it safely with Autoptimize or LiteSpeed Cache without breaking scripts.
A CDN speeds up your WordPress site by serving static files from servers closest to your visitors. Here’s how to set one up using BunnyCDN and what to pair it with.
Learn how to improve Core Web Vitals in WordPress by fixing LCP, CLS, and INP. Covers image optimisation, lazy loading, caching, and reducing JavaScript.
Browser caching speeds up your website by storing static files on visitors’ devices after their first visit. This guide shows you how to enable it using a caching tool like LiteSpeed Cache or by editing your .htaccess file directly.
GZIP compression cuts text-file transfer sizes by 60-80% with zero visual change — how to check if it’s already on, enable it if it isn’t, and why Brotli usually beats it when both are available.
Lazy loading delays the loading of images and iframes until they enter the viewport, reducing initial page load time and improving Core Web Vitals scores. This guide explains how WordPress handles lazy loading natively, what isn’t covered by default, and how to extend it using a caching plugin or the Performance Lab plugin.
A slow WordPress site costs visitors and search rankings. This guide covers the practical steps to improve WordPress speed and mobile performance — caching, image optimisation, minification, CDN setup, and the common mistakes that undo the gains.
WebP is still the safe, zero-setup default — but AVIF has closed the browser-support gap enough by 2026 (93-95% coverage, 20-30% smaller than WebP) that it’s worth knowing when the upgrade is actually worth the extra setup.
Google PageSpeed Insights gives you a performance score for your site and flags exactly what’s slowing it down. This guide explains how to read the report, understand Core Web Vitals, and make practical improvements — without needing a developer.
