Core Web Vitals

Pass every Core Web Vitals threshold — and watch rankings follow

Google weights LCP, INP, and CLS from real-user field data, not your Lighthouse score. We fix both, instrument the impact, and report on organic revenue gained.

The problem we solve

Lab scores look fine — field data tells a different story

Lighthouse passes in staging but Chrome UX Report shows 41 % of your real users hitting poor LCP. Google's Page Experience signal uses CrUX field data, so that gap costs you rankings every day. We close it with targeted engineering, not superficial optimisations.

What's included

Everything in your Core Web Vitals programme

LCP Root-Cause Audit

We trace every LCP candidate — render-blocking resources, server TTFB, lazy-loaded heroes — and fix the dominant bottleneck first.

INP Diagnosis & Patching

We profile long tasks and interaction delays in the main thread, refactor event handlers, and defer non-critical JS to cut INP below 200 ms.

CLS Attribution

We identify every unsized image, injected banner, and web-font FOUT contributing to layout shift, then eliminate each root cause at the DOM level.

CrUX Field Monitoring

We set up continuous CrUX and RUM dashboards so regressions surface within 24 hours, not after a ranking drop.

Image & Font Pipeline

AVIF/WebP encoding, responsive srcset, font preloading, and size-hint attributes implemented across your entire image and typography stack.

Dev Team Integration

We write scoped tickets, pair with your engineers, or ship directly — and validate every fix in the CrUX origin summary before closing.

Our methodology

From field data diagnosis to shipped fixes

1

Field Data Baseline

We pull 28-day CrUX data by page segment, overlay your Search Console performance, and rank every URL by traffic × failure rate to prioritise what actually moves revenue.

2

Root-Cause Fix Sprints

Each metric gets a dedicated fix sprint: LCP resource chain, INP interaction map, CLS shift log. Fixes are scoped by effort and shipped biggest-impact first.

3

Validate & Report

We confirm field data greens out in CrUX and Search Console Page Experience, then quantify ranking and click changes in a revenue-attributed monthly report.

Proof it works

How a technical overhaul unlocked 187% more revenue

A fast-growing marketplace was leaking authority through duplicate URLs and slow templates. We re-architected crawling, halved load times, and rebuilt their internal linking.

Service FAQ

Questions, answered

Lab scores (Lighthouse, PageSpeed Insights) run in a controlled environment. Field data is aggregated from real Chrome users via the CrUX dataset. Google's ranking signal uses field data, so that is what we target.
Google updates Page Experience signals roughly monthly. Most clients see CrUX scores green within 4-6 weeks of shipping fixes, with ranking response typically lagging 4-8 weeks after that.
Yes. We scope fixes to what can be shipped — CDN-level image optimisation, script tag changes, and CSS adjustments often move the needle without a full redeploy.
Google uses mobile field data as the primary signal for the majority of sites. We fix both, but we prioritise mobile CrUX segments first.
