Proof is a process.
Not a promise.
A transparent way to demonstrate website performance work, without inventing client results or guaranteeing scores.
Everything measured.
Everything explained.
Our project reporting separates lab testing from real-user Core Web Vitals. We document testing conditions and compare meaningful pages, so you can see what was done and what still depends on third parties.
Real-world Core Web Vitals reporting can take time to reflect changes because field data is collected over a rolling window.

Website performance testing should compare consistent mobile and desktop conditions. Our reporting connects PageSpeed Insights scores, GTmetrix results, Core Web Vitals, LCP, INP, CLS, server response and page-load findings to the work completed.
Performance testing and reporting questions
How do you measure website speed before and after optimization?
We record the covered URL, device profile and test conditions, then compare repeat PageSpeed Insights and GTmetrix tests before and after implementation.
Why do PageSpeed scores change between tests?
Lab scores can move because of network routing, server response, third-party content and test conditions. The guarantee uses an agreed profile and a median of three final tests.
What is included in the final performance report?
The report records the work completed, relevant before-and-after results, remaining platform constraints and any recommendations that fall outside the agreed scope.
Do you test website functionality after optimization?
Yes. The agreed templates, responsive layouts and critical journeys are checked so performance work does not introduce functional or design disruptions.
