Performance audit

Every second of load time costs you sales.

A slow site means a higher bounce rate, more abandoned carts, and a bad signal to Google. The performance audit pinpoints exactly what's slowing your site down and in what order to fix it. Report within 7 business days, €490.

Web performance is no longer a technical detail reserved for developers: it directly impacts conversion rate and Google ranking (Core Web Vitals). This audit measures real load times on mobile and desktop, identifies render-blocking resources (third-party scripts, unoptimized images, slow server queries), and delivers a concrete optimization plan, not a list of indecipherable metrics. Performance is not the Lighthouse score, which measures a laboratory load.

What matters are Core Web Vitals measured on your real visitors, with their connections and their devices. The audit starts there, then traces the causes: unoptimised images, blocking JavaScript, database queries that explode as the catalogue grows, misconfigured caching, undersized hosting. Each cause comes with an expected gain, which separates what is worth doing from micro-optimisation.

Features

What you get.

01

Core Web Vitals measurement

LCP, INP, CLS measured on mobile and desktop, under real-world conditions (not just lab data).

02

Server & hosting audit

Server response time (TTFB), cache configuration, slow database queries.

03

Front-end resource audit

Unoptimized images, blocking third-party scripts, unminified CSS/JS, poorly loaded fonts.

04

Competitor comparison

Your load times compared to 2-3 direct competitors on the same page types.

05

Costed optimization plan

Each fix accompanied by an estimated time gain and effort level.

FAQ

Frequent questions

What speed gains can I expect? +
Highly variable depending on the site's current state, but a 30-60% load time improvement is common after applying the identified quick wins.
Does the audit include the optimizations? +
No, only the diagnosis and plan. Implementation can be handled as a fixed-price project or monthly maintenance.
Is this tied to my current hosting? +
The audit works on any hosting. If the hosting itself is the limiting factor, it will be clearly flagged in the report.
Do you measure performance under real-world conditions or only in a lab? +
Both: lab measurements (controlled, reproducible conditions) and, when data is available, real-world field data (CrUX) from your actual visitors on mobile and desktop.
Does a fast site really improve SEO? +
Yes, Core Web Vitals (LCP, INP, CLS) are officially part of Google's ranking criteria. This direct link between speed and SEO is detailed in the report.
What tools do you use for the audit? +
Lighthouse, PageSpeed Insights, WebPageTest and server profiling tools, combined with manual code analysis — automated scores alone are never enough to build a real action plan.
