Website speed optimisation measured in the field
Lab scores are a diagnostic. Field data is the truth. We optimise until real users on real phones get a fast page.
- Field and lab performance audit
- Critical rendering path optimisation
- Image, font and asset delivery pipeline
- JavaScript and third-party script reduction
- Caching and CDN configuration
- Performance budgets and monitoring
Overview
What our website speed optimisation work actually involves
We work from CrUX field data and your own RUM, not a single Lighthouse run on a fast laptop. Then we cut what is actually slowing the page: render-blocking assets, oversized images, third-party tags and main-thread congestion.
The work is measured on the metrics search engines use — LCP, INP, CLS — and on the metric your finance team uses, which is conversion rate.

FAQ
Website Speed Optimisation — questions we get asked
How much can you improve our scores?
Most unoptimised sites can reach 'good' on all three Core Web Vitals. Sites with heavy third-party dependencies may need business decisions about which tags stay.
Does speed really affect rankings?
It is a real but modest ranking factor. The bigger effect is on bounce and conversion rate, which is where the money is.
Do you work on Shopify and WordPress?
Yes — both are common, and both have well-understood speed problems we have fixed many times.
