Core Web Vitals & metrics

Metric Before After Change
First Contentful Paint 2.5 s 0.9 s −64%
Largest Contentful Paint 5.2 s 2.8 s −46%
Total Blocking Time 150 ms 40 ms −73%
Cumulative Layout Shift 0 0 —
Speed Index 3.4 s 4.2 s +24%

Lighthouse scores vary between runs. Speed Index saw a minor fluctuation while remaining within thresholds. The overall Performance score jumped +18 points thanks to large improvements across FCP, LCP, and TBT.

What I changed

01

Critical render path

Highest impact — targets LCP & FCP
  • Self-hosted Google Fonts as WOFF2 — eliminated 3 render-blocking requests
  • Deferred GSAP & Iubenda scripts — freed up ~760 ms of main-thread time
  • Preloaded the LCP hero image so it starts downloading immediately
  • Moved <meta charset> to the very first position in <head>
02

Image optimisation

~527 KiB saved across all pages
  • Switched to Astro's <Image> component for automatic format & size optimisation
  • Converted remaining PNGs to WebP
  • Added responsive srcset so mobile devices download appropriately sized images
03

JavaScript optimisation

~163 KiB unused JS removed
  • Installed GSAP via npm — tree-shakes unused modules, eliminates CDN duplication
  • Lazy-loaded Chatwoot SDK until idle or user interaction
  • Deferred PostHog analytics after first paint via requestIdleCallback
04

Caching & security headers

Faster repeat visits & hardened security
  • Added immutable cache headers for fonts, images, and JS (1 year TTL)
  • Added Strict-Transport-Security, Content-Security-Policy, X-Frame-Options and more
05

Accessibility fixes

95 → 100 Accessibility score
  • Added <main> landmark to every page for screen reader navigation
  • Darkened muted text colour from #7A7A72 to meet WCAG AA 4.5:1 contrast ratio
