What we audit and fix
Image and font optimisation: modern formats (AVIF, WebP), proper sizing, lazy loading, font-display tuning. JavaScript bundles: code splitting, tree-shaking, third-party script auditing (analytics, chat widgets, ad pixels). CSS critical path extraction so first paint happens fast even on slow connections. Server response time: caching strategy at edge and origin, CDN setup or migration, database query tuning when slow queries dominate.
