Website Performance Optimization

Slow pages cost you rankings and conversions. I diagnose and fix Core Web Vitals on Webflow sites — largest-contentful-paint, layout shift, and interaction latency — so pages feel instant and pass Google's thresholds.

Performance work starts with real data, not guesses: field data from Chrome UX Report and lab data from Lighthouse, on a throttled mobile profile, to find what's actually slowing the page rather than what feels slow. From there it's methodical — right-sizing and reformatting images, deferring non-critical scripts, taming heavy animation and third-party embeds, and stabilising layout so nothing jumps as it loads.

The goal isn't a vanity Lighthouse score in a lab — it's passing Core Web Vitals on real devices, because that's what Google measures and what your visitors feel.

What you get

Field + lab diagnosis

CrUX and Lighthouse on throttled mobile to find the real bottlenecks.

Image optimisation

Modern formats, correct sizing, and lazy loading.

Script + animation audit

Deferring and trimming what blocks the main thread and hurts INP.

Layout stability

Reserved space and font strategy to eliminate layout shift.

Performance Optimization FAQs

Can you improve my Core Web Vitals score?
Yes. I work from real field and lab data to fix the specific issues hurting LCP, CLS, and INP, and re-measure on a throttled mobile profile so the improvement reflects real devices.
Does heavy animation have to slow the site down?
No — but it often does when it's built carelessly. I keep GSAP and scroll interactions off the critical path and honour reduced-motion, so motion doesn't come at the cost of INP.
