Performance Optimization
Page speed is not a vanity metric. Google uses Core Web Vitals as a ranking signal — a slow site ranks lower, regardless of how good the content is. And separately from rankings, a slow site loses visitors before they've had a chance to become customers. We measure, diagnose, and fix both problems.
Key Capabilities
- A full performance audit using Lighthouse, PageSpeed Insights, and real-device testing — not just synthetic benchmarks from a fast connection.
- Largest Contentful Paint (LCP) improvements: image format optimisation (WebP/AVIF), preloading, server response time analysis.
- Cumulative Layout Shift (CLS) fixes: explicit dimensions on images and embeds, font loading strategy, eliminating JavaScript that causes reflow.
- First Input Delay / Interaction to Next Paint (INP) reductions: script deferral, third-party tag audit, render-blocking resource removal.
- Technical SEO corrections: proper heading hierarchy, canonical URLs, structured data, missing alt text, broken internal links.
- A before/after report with Lighthouse scores, field data (where available), and explanation of what was changed and why.
Who It's For
Performance optimization is for businesses where the website already exists but is underperforming in search or losing visitors to slow load times. Common signs: Lighthouse Performance score below 70, Core Web Vitals showing red or orange in Search Console, or a noticeably slow site on mobile.
It's also a good fit after a redesign that prioritised visual quality and added weight to the page without balancing it with performance work — a common outcome when design and development are handled by separate teams.
Our Process
A measurably faster site with Core Web Vitals scores that pass Google's thresholds, and a written summary of everything that was changed so you understand what was done and why — not just a before/after screenshot.
Where performance issues are structural (the site's architecture requires a rebuild to fix properly), we'll say so clearly in the audit report before we do any paid work — so you can decide whether optimization or a rebuild is the right investment.
