Website Performance Optimisation

Website performance isn't optional. Google uses Core Web Vitals as a ranking factor, and studies consistently show that even a one-second delay in page load can reduce conversions by up to 7%. At CodeDrips, we diagnose and fix performance bottlenecks to deliver measurably faster websites.

Core Web Vitals Optimisation

Google's Core Web Vitals measure real-world user experience across three key metrics:

• Largest Contentful Paint (LCP): How quickly the main content loads. We optimise images, fonts, server response times, and rendering paths to achieve sub-2.5 second LCP.
• Interaction to Next Paint (INP): How responsive your site is to user interactions. We reduce JavaScript execution time, optimise event handlers, and minimise main-thread blocking.
• Cumulative Layout Shift (CLS): How stable your layout is during loading. We fix layout shifts caused by images without dimensions, dynamically injected content, and web fonts.

What We Optimise

• Image & Media Optimisation: Modern formats (WebP, AVIF), responsive images, lazy loading, and CDN delivery for dramatically reduced page weight.
• JavaScript Performance: Code splitting, tree shaking, deferred loading, and bundle analysis to eliminate render-blocking scripts.
• Server & Hosting: CDN configuration, edge caching, server-side rendering, and hosting infrastructure recommendations for optimal TTFB.
• CSS & Rendering: Critical CSS extraction, unused CSS removal, and efficient rendering pipelines for faster visual completeness.
• Third-Party Scripts: Audit and optimisation of analytics, chat widgets, tracking pixels, and other third-party scripts that often silently degrade performance.
• Caching Strategy: Browser caching, service workers, and stale-while-revalidate patterns for returning visitors.

Our Performance Process

1. Audit & Benchmarking: We run a comprehensive performance audit using Lighthouse, WebPageTest, and real-user monitoring data to establish baselines and identify bottlenecks.
2. Prioritised Roadmap: Not all fixes are equal. We rank optimisations by impact and effort, so you get the biggest improvements first.
3. Implementation: Our engineers implement the optimisations directly, whether it's refactoring frontend code, configuring CDNs, or optimising your CMS setup.
4. Verification & Reporting: We re-test after every change and provide clear before/after metrics so you can see the results.
5. Ongoing Monitoring: Performance degrades over time as content and features are added. We offer ongoing monitoring and maintenance to keep your site fast.

Platform Expertise

We optimise sites built on Shopify, WordPress, Next.js, Gatsby, CraftCMS, Sanity, and custom platforms. No matter your tech stack, we can make it faster.
