PERFORMANCE OPTIMISATION

Website speed directly impacts your bottom line. Research consistently shows that every 100ms of additional load time costs 1% in conversion rate. For European e-commerce businesses, that can mean thousands of euros in lost revenue each month. Our performance optimisation service identifies and eliminates every bottleneck slowing your website down.

We start with a comprehensive performance audit using Lighthouse, WebPageTest, and Chrome DevTools. We measure Core Web Vitals including Largest Contentful Paint, First Input Delay, Cumulative Layout Shift, and Interaction to Next Paint. Each metric is benchmarked against your competitors and industry standards so you know exactly where you stand.

Image optimisation often delivers the biggest wins. We implement next-gen formats like WebP and AVIF with automatic fallbacks, responsive images with srcset for different screen sizes, lazy loading for below-the-fold content, and proper width and height attributes to prevent layout shifts. For hero images and LCP elements, we use priority loading to ensure they appear instantly.

JavaScript is the second biggest performance bottleneck. We implement code splitting to break your bundle into smaller chunks loaded on demand. Tree shaking eliminates unused code. Dynamic imports defer heavy libraries until they are needed. We audit third-party scripts and remove or defer those that block rendering. Bundle analysis identifies the largest dependencies and finds lighter alternatives.

Server-side optimisation includes proper cache headers, CDN configuration, Brotli compression, and edge computing for dynamic content. Database queries are optimised with proper indexing, query planning, and connection pooling. API responses are cached at multiple levels to reduce server load and improve response times.

Font loading is optimised with font-display: swap, subsetting to include only needed characters, and preloading critical font files. CSS is purged of unused styles and critical CSS is inlined in the document head. The result is a website that paints meaningful content in under 1 second and becomes fully interactive in under 2 seconds on a 4G connection.
