WordPress Performance
WordPress Performance covers the technical changes that affect how fast a site loads and how efficiently it delivers content — caching, image optimisation, lazy loading, GZIP compression, database cleanup, CDN setup, browser caching, converting images to WebP, HTTP security headers, and using tools like Google PageSpeed Insights to find the actual bottleneck rather than guessing at one.
Page speed affects both search rankings and visitor behaviour in ways that are easy to measure and hard to ignore. Visitors abandon slow pages before they’ve read anything, and speed is something Google weighs on both desktop and mobile. The performance issues that affect most WordPress sites aren’t obscure — they’re the predictable result of skipping a handful of well-understood configuration steps.
The articles here focus on changes that make a genuine difference on a typical WordPress install, without needing server administration skills or a developer working at the infrastructure level.
