Core Web Vitals Optimisation for Service Websites

Potential clients judge your credibility in seconds. Poor loading speed kills trust. Focus on Core Web Vitals to keep every visitor engaged.

Measure baseline performance

Use PageSpeed Insights, Lighthouse and Chrome User Experience Report to capture real-user metrics. Record LCP, INP and CLS across desktop and mobile. Prioritise pages driving leads: home, services, case studies.

Optimise render path

• Serve next-gen images (WebP/AVIF) via CDN with responsive breakpoints.
• Inline critical CSS and defer non-essential scripts. Audit third-party tags quarterly.
• Implement server-side caching and HTTP/2.

Stabilise layout and interactions

Reserve space for media, preload fonts and eliminate layout shifts caused by pop-ups. Optimise interaction handlers to keep INP under 200ms.

Keep performance culture alive

Automate monitoring with WebPageTest or Calibre. Embed performance budgets into deployment pipelines so regressions trigger alerts. Your website becomes a sales-ready asset, not a bottleneck.
