Performance

From Slow Site to 90+ PageSpeed Score

A slow website loses rankings, loses conversions and loses customers. We diagnose every bottleneck and fix it — from server config to image pipelines — turning slow sites fast and keeping them that way.

Performance Optimisation — Full Scope

We work at every layer: server, application, network and browser — fixing the actual causes, not just the symptoms.

Core Web Vitals (LCP/CLS/INP)
Fix Largest Contentful Paint, Cumulative Layout Shift and Interaction to Next Paint — the metrics Google uses as ranking signals since 2021.
Image Optimisation Pipeline
Convert all images to WebP/AVIF, implement srcset for responsive images, add lazy loading and generate LQIP (Low Quality Image Placeholders) for instant visual feedback.
JavaScript & CSS Optimisation
Remove unused CSS (PurgeCSS), defer non-critical JS, tree-shake bundles, code-split by route and inline critical CSS for above-the-fold content.
Server-Side Caching
Redis or Memcached object caching, full-page caching (WP Rocket, Nginx FastCGI Cache or custom), database query caching and PHP OPcache tuning.
CDN Setup & Configuration
Cloudflare (free or Pro), BunnyCDN or AWS CloudFront — static asset delivery, smart caching rules, minification at the edge and image resizing CDN.
Database Optimisation
Slow query analysis, index tuning, transient cleanup, autoload option reduction and WooCommerce order table archiving for large MySQL databases.
HTTP/2 & Server Tuning
Enable HTTP/2 multiplexing, GZIP/Brotli compression, keep-alive connections, DNS prefetch headers and optimal TLS configuration for TTFB reduction.
Monitoring & Alerting
PageSpeed CI integration to catch regressions on every deploy, Datadog/UptimeRobot monitoring, Core Web Vitals alerting via Search Console.

Frequently Asked Questions

90+ on both mobile and desktop. Google uses Core Web Vitals (LCP, CLS, INP) as confirmed ranking signals. A score below 50 can actively hurt your search rankings and definitely hurts your conversion rate.
Google simulates a mid-range Android device on slow 4G for mobile tests. This is how most of the world actually loads your site. Mobile score is the one that matters most for SEO — we always prioritise mobile optimisation first.
We always work on a staging copy first, test every change and only push to production after confirmation. We document every change so anything can be reversed if needed.
Yes — WooCommerce has unique caching challenges (cart pages cannot be cached). We configure smart cache exclusions, bypass rules, session handling and checkout-specific optimisations that generic WordPress speed guides miss.
We set up PageSpeed CI (continuous monitoring), configure cache purging on content updates and provide a post-optimisation guide for your content team on image sizes, plugin hygiene and what to avoid.
