Performance & Speed Optimization

Performance that supports visibility and conversion

Slow pages cost attention, enquiries and trust. We investigate the real causes across your front end, hosting and APIs, then make targeted improvements that benefit visitors and your Core Web Vitals—not a generic cache-plugin installation.

What we investigate and optimise

  • Lighthouse / Web Vitals baseline and target plan
  • Asset strategy: images, fonts, code splitting, lazy loading
  • Server and CDN caching for custom apps
  • Database and API response tuning
  • Rendering path improvements (SSR/ISR/static where useful)
  • Before/after report with measurable gains

Our approach

We start with a baseline on the pages and devices that matter to your audience. The work is prioritised by expected impact and technical effort, tested in a safe environment and measured again after release.

What you receive

  • Performance baseline and prioritised action plan
  • Implemented improvements across code, assets or infrastructure
  • Before-and-after Core Web Vitals evidence
  • Clear explanation of trade-offs and remaining opportunities
  • Recommendations for keeping performance stable as the site grows

Ideal for

  • Lead-generation and e-commerce websites
  • Custom PHP or Next.js applications with slow journeys
  • Teams preparing a campaign, redesign or SEO push
  • Businesses that need evidence before investing in a rebuild

How to start

Share the affected URLs, your analytics context and any recent changes. We assess the highest-value performance work and propose a focused optimisation sprint.
