The Situation
An established law firm had been running a WordPress site for three years. The site had accumulated plugins, bloated themes, and unoptimized images. Page load times had crept above 4 seconds, and Google's Core Web Vitals were consistently failing.
Mobile traffic — which accounted for over 60% of their visitors — was bouncing at alarming rates. Google had started factoring page experience into rankings, and their competitors with faster sites were climbing while they dropped.
The Challenge
4.2-second load time driving away mobile visitors
PageSpeed 38/100 desktop, 42/100 mobile
18 active plugins creating render-blocking requests
Core Web Vitals failing — LCP, FID, and CLS all red
The Strategy
Complete Astro Rebuild
Rebuilt every page from scratch on Astro — a modern static site generator that ships zero JavaScript by default. The result is HTML that loads instantly, with no framework overhead, no unused CSS, and no render-blocking scripts.
Mobile-First Design
Designed for small screens first, then scaled up. Touch targets, font sizes, spacing, and navigation were all built around thumb-friendly mobile interactions. Desktop is the enhancement, not the default.
Image Optimization
Replaced unoptimized PNGs and JPEGs with modern WebP/AVIF formats, implemented responsive srcset attributes, and added lazy loading. Total image payload dropped by over 80%.
Schema & SEO Preservation
Maintained all existing URL structures with proper 301 redirects where needed. Added comprehensive schema markup — Organization, LegalService, BreadcrumbList — that the WordPress site never had.

Key Takeaway
Your website's speed isn't just a number. It's a ranking factor, a user experience factor, and a conversion factor. A slow WordPress site with 18 plugins isn't just annoying — it's costing you rankings and clients every single day.
