What I do

Comprehensive website performance optimisation covering image optimisation, code minification, caching strategies, and Core Web Vitals improvements. Delivering faster, more efficient websites that provide better user experiences.

Image Optimisation

Converting images to modern formats (WebP, AVIF), implementing responsive images, and lazy loading to reduce page weight significantly.

Code Optimisation

Minifying CSS and JavaScript, removing unused code, implementing code splitting, and optimising critical rendering path.

Caching Strategy

Implementing browser caching, server-side caching, and CDN configuration to reduce server load and improve repeat visit speeds.

Core Web Vitals

Targeted improvements to LCP, FID, and CLS metrics to meet Google thresholds and improve search rankings.

Third-Party Optimisation

Auditing and optimising third-party scripts, analytics, ads, and embeds that often slow down websites.

Quality Assurance

Testing all optimisations to ensure functionality remains intact while performance improves. No broken features.

FAQ

Frequently asked questions

Common questions about website performance optimisation. If you have a specific question not covered here, feel free to get in touch.

Improvements vary by site condition. Typically see 30-60% reduction in load times, with Core Web Vitals moving from poor to good range. Some sites see even larger gains. I provide estimates after initial audit.

No. All optimisations are tested to ensure visual quality and functionality remain intact. Images maintain acceptable quality, and all features continue working as expected.

Most optimisation projects take 1-3 weeks depending on site complexity and scope. Larger sites with many pages or complex functionality may take longer.

Yes. I optimise WordPress, Shopify, custom builds, and any CMS. Optimisation techniques vary by platform, but performance principles apply universally.

Not necessarily. Optimisation often improves performance significantly without hosting changes. If hosting is a bottleneck, I will advise, but it is not always required.

Yes. I can set up ongoing monitoring and provide regular performance reports. This helps catch any regressions and ensures optimisations continue delivering value.
