Performance Engineering
Core Web Vitals Optimisation
Improve speed and user experience through technical audits, caching, asset compression, and rendering optimisation.
Performance work starts with measurement, not simply installing a cache plugin. We review laboratory and real-user data to identify the constraints that genuinely affect visitors.
Measurement focus
- Largest Contentful Paint (LCP): how quickly the primary content appears.
- Interaction to Next Paint (INP): how quickly the page responds after an interaction.
- Cumulative Layout Shift (CLS): how stable the layout remains while loading.
Optimisation scope
- Audit rendering paths, JavaScript, CSS, fonts, and image assets.
- Prioritise important resources in the first viewport.
- Serve compressed images sized for the user's device.
- Reduce unnecessary JavaScript and main-thread work.
- Improve browser, CDN, and server-side caching strategies.
- Prevent layout shifts by reserving clear dimensions for media.
Intended outcome
The website feels faster, more stable, and more responsive. These improvements support user experience and technical SEO readiness, but they are not presented as a guarantee of any particular ranking.
