What it means to minify CSS and JavaScript, how it works alongside gzip and Brotli, which build tools and plugins do it, and how to measure the real saving.
The Core Web Vitals thresholds for LCP, INP and CLS, why Google uses the 75th percentile, field vs lab data, and a step-by-step way to test your own pages.
Speed up WordPress in the right order: hosting and PHP version, page and object caching, a plugin audit, image handling and front-end cleanup.
Measure what makes up your Time to First Byte, then cut it with page caching, a CDN, fewer redirects, faster database queries and better hosting.
Why your PageSpeed Insights score jumps between runs, how lab and field data differ, why mobile scores lower than desktop, and which numbers matter.
Break LCP into its four sub-parts, find which one is slow, and fix it with preload, fetchpriority, right-sized images and a faster server response.
Cut image weight without losing quality: when to use WebP or AVIF, how to write srcset and sizes, when to lazy load, and how to compress sensibly.
Find the interactions dragging down INP, then fix them by breaking up long tasks, taming third-party scripts and yielding to the main thread.
Find the elements causing layout shift and fix them: image dimensions, reserved space for ads and embeds, font fallbacks, banners and animations.
What makes CSS and JavaScript render-blocking, and how to fix it with critical CSS, defer and async, media attributes and smarter font loading.
When a CDN actually speeds up a small business site, when it does little, what can go wrong when you set one up, and how to choose between the options.
