WordPress speed optimization for speaking coach: Case Study

We built a turnkey website with our design partners and tackled common myths about WordPress by baking performance into the development process from day one, delivered as part of our WordPress optimization services.

Because the site was created from scratch, we set a performance budget, tracked Core Web Vitals (LCP, INP, CLS) on every page, and designed mobile-first to keep real-world UX fast—even years after launch.

We validated the build with PageSpeed Insights (Lighthouse lab data) and CrUX field signals, then reviewed waterfalls in GTmetrix to distinguish render-blocking issues from server/TTFB delays — our standard workflow for Google PageSpeed optimization.

We used native lazy-loading for images and iframes and added lightweight placeholders/skeletons for media sections. Non-critical blocks render after first paint, which improves LCP/INP and prevents layout shifts on scroll.

We compressed images, enforced explicit dimensions, served modern formats (WebP/AVIF) with JPEG/PNG fallbacks, and used responsive srcset/sizes. Hero assets were marked with fetchpriority=”high” to speed up first render — an approach aligned with our mobile optimization for WordPress websites.

We kept CSS lean and well-structured, extracted critical CSS, and minified production styles. This reduced render-blocking work and stabilized layout across templates.

Non-essential scripts load with defer/async and are code-split by route. We added preconnect/preload for key origins and delayed third-party scripts until user intent or consent to cut main-thread work and improve INP.

The site launched green without heavy optimizers; we later introduced a lightweight plugin for ongoing housekeeping (small asset tweaks, selective script unloading) while keeping the core stack simple.

We confirmed HTTP/2/3, modern PHP with OPcache, and enabled page/browser caching with sensible TTLs. A CDN can be layered for global delivery without changing the core architecture.
