Core Web Vitals

Pass Every Google Performance Threshold

We audit, diagnose, and fix LCP, INP, and CLS at the code level — so your site loads instantly, ranks higher, and keeps visitors engaged from the first paint.

Real-User Data First

We start with CrUX field data — actual user experience scores, not just lab simulations.

Code-Level Fixes

No plugin guesswork. We implement structural improvements at the image, JS, CSS, and server layers.

Regression Monitoring

30-day post-deployment monitoring ensures scores stay green after every code release.

What We Fix

Four targeted workstreams covering every Core Web Vitals metric and the server-side factors that underpin them.

LCP Optimization

Reduce Largest Contentful Paint below 2.5 s through image compression, server response improvements, render-blocking resource elimination, and CDN tuning.

🖱️

INP Reduction

Diagnose and eliminate long JavaScript tasks, event-handler bottlenecks, and third-party script delays that inflate Interaction to Next Paint scores.

📐

CLS Elimination

Reserve explicit dimensions for all media and ads, prevent late-loading font swaps, and fix dynamic injections that cause layout instability.

🚀

TTFB & Server Performance

Optimise server response times via caching strategies, edge delivery, and database query tuning so every byte arrives faster.

Frequently Asked Questions

What are Core Web Vitals and why do they affect rankings?

Core Web Vitals — LCP, INP, and CLS — are Google's official real-user experience metrics. Sites that pass all three thresholds receive a positive page-experience ranking signal; sites that fail are disadvantaged against comparable content.

How long does Core Web Vitals optimization take?

Most quick wins (image optimisation, render-blocking scripts) can be deployed in 1–2 weeks. Full structural work including server-side changes and JS architecture improvements typically takes 3–6 weeks.

Do you work on WordPress, Shopify, and custom stacks?

Yes. We have optimisation playbooks for WordPress (WP Rocket, WP Optimize), Shopify (Dawn, custom themes), Next.js, and custom stacks using Cloudflare and CDN layers.

Will speed optimisation break my site's design?

No. We work within your existing design system. All changes are staged, reviewed, and deployed with rollback capability — your brand appearance is preserved throughout.
