PERFORMANCE OPTIMISATION

Speed That
Drives Revenue.

Every 100ms of load time costs you conversion rate. We audit, fix, and optimise your website's Core Web Vitals so you rank higher in Google and convert more of the traffic you already have.

How We Work

Our Process

01

Audit

We run a full Core Web Vitals audit across your key pages using both lab data (Lighthouse) and field data (CrUX). Every issue is documented with its business impact, not just a technical score.

02

Prioritise

We rank fixes by effort versus conversion impact. Quick wins are shipped first. Larger architectural changes are scoped as separate workstreams so momentum never stops.

03

Implement

We make the changes directly in your codebase or CMS, working alongside your existing tech team. Every fix is tested in staging before it goes anywhere near production.

04

Monitor

We set up monthly Lighthouse monitoring and CrUX tracking so regressions are caught before they affect rankings or conversion rates.

FAQ

Common Questions

Core Web Vitals are a confirmed Google ranking signal. Poor scores can suppress rankings, particularly in competitive categories. More directly, they affect conversion rate through load time and layout stability.

Yes. Most of our performance work is on Shopify stores. There are real limits to what Shopify's platform allows, but there is usually significant headroom before those limits become relevant.

For implementation work, yes. For the audit report, we only need the live URLs. We agree access requirements upfront before any work begins.

An audit takes 3 to 5 days. Implementation timelines depend on the volume and complexity of fixes, typically 2 to 6 weeks for a full remediation project.
