Website Performance Optimization
Making websites load and respond faster by improving Core Web Vitals, server response, images, scripts, fonts, caching and third-party tags, measured with real user data rather than lab scores alone.
Capability overview
What website performance optimization involves
Slow websites lose visitors, enquiries and sales, especially on mobile networks. Google's Core Web Vitals measure loading with Largest Contentful Paint, responsiveness with Interaction to Next Paint and visual stability with Cumulative Layout Shift, and they reflect real user experience recorded in the Chrome User Experience Report.
Optimisation starts by finding the specific causes on your templates. Common fixes include serving modern image formats at correct sizes, reducing unused JavaScript and CSS, loading third-party tags later, preloading critical resources, improving font loading, adding page and object caching, using a CDN and reducing server response time.
Lab tools such as Lighthouse guide investigation, but success is measured with field data from real visitors, because a high lab score does not always mean users experience a fast site.
What is included
Optimisation areas
Core Web Vitals diagnosis
LCP, INP and CLS issues identified by template using field data, Lighthouse, WebPageTest and browser profiling.
Media optimisation

Ask a questionLab tests vary with server response, network simulation and third-party scripts. Trends and field data are more reliable than a single score.
Caching and optimisation plugins help, but heavy themes, page builders, excessive plugins, slow hosting and third-party scripts often require code or infrastructure changes.
Page experience is one of many ranking signals. Speed improvements mainly help users and conversions, while also supporting search performance when content quality is strong.
A performance audit is fixed price. Implementation is quoted based on templates, platform, code changes and hosting improvements.
