Core Web Vitals Optimisation
Google uses Core Web Vitals as real-world signals of user experience. We improve LCP, INP and CLS with technical fixes, code-level changes and ongoing monitoring — so your pages feel fast, stable and ready to compete in search.
Largest Contentful Paint
Find what delays the main paint — images, fonts, server response — and ship fixes that move the score.
Interaction to Next Paint
Trim heavy scripts, defer non-critical work and remove input delays that frustrate taps and clicks.
Cumulative Layout Shift
Reserve space for media and embeds, stabilise fonts and stop content jumping as the page loads.
Performance is a ranking signal
From audit to shipped improvements
We baseline your priority URLs against real traffic, then implement fixes in order of impact — not a PDF you file away. You get before/after metrics, a clear backlog and a way to keep scores healthy as you ship new content.
“After the sprint, our product pages stopped jumping on load and LCP improved sharply. Search Console finally matched what customers were experiencing.”

Core Web Vitals that match real users
Lab scores are useful; field data is the truth. We optimise for the metrics Google uses in ranking systems and that visitors feel on your priority pages.
- Field and lab baselines
- CrUX, Search Console, our speed test and synthetic runs so we agree what to fix first — on mobile and desktop.
- LCP: faster meaningful paint
- Images, fonts, caching and server tuning to cut time to the largest contentful paint.
- INP: responsive interactions
- JavaScript budgets, third-party scripts and main-thread work trimmed so interactions feel instant.
- CLS: visual stability
- Dimensions for media, font behaviour and dynamic slots so layouts stop shifting.
- Works with ranking growth
- Pair with page ranking growth so technical speed meets managed search engagement on your priority URLs.
- Ongoing checks
- Catch regressions after releases — performance is never “done”.
