Performance audit

Every second of load time costs you sales.

A slow site drives people away: visitors leave before the page has even shown, abandon their carts more often, and Google notices. This audit pinpoints exactly what is slowing your site down and in what order to fix it. Report within 7 business days, €490.

The detail: LCP, CLS, page weight, requests
What to fix, ranked by expected gain

In detail

A site's speed is no longer a detail reserved for developers: it bears directly on sales and on Google ranking. This audit measures real times on mobile and desktop, spots what blocks the display (code from external services, images too heavy, a server that answers slowly), and delivers a concrete fix plan, not a list of indecipherable metrics. Speed is not the Lighthouse score, Google's testing tool, which measures a load under laboratory conditions.

What counts are the Core Web Vitals, the measurements Google collects from your real visitors, with their connections and their phones. The audit starts there, then traces the causes: images never slimmed down, scripts that block the display (code the page runs before showing itself), database requests that grow heavier with the catalogue, badly set caching (the memory that saves recalculating everything), hosting cut too fine. Each cause is priced in expected gain, which separates what is worth doing from marginal tinkering.

Features

What you get.

The speed your visitors actually get

Google's speed and stability measurements (Core Web Vitals), collected on mobile and desktop, under real conditions and not just in the lab.

The server gets examined too

Your hosting's reaction time, cache settings (the memory that saves recalculating everything), requests to the database that run too slow.

What weighs your pages down

Images too heavy, external services' code blocking the display, files never slimmed down, badly loaded fonts: everything that delays the page is listed.

Compared with your competitors

Your load times compared with those of 2 to 3 direct competitors, on the same page types.

A plan priced in seconds saved

Every fix comes with the expected time gain and the level of effort required: you see straight away what is worth doing.

1-2 days

Diagnosis

I identify what blocks the display and where the server loses time.

Real cases

A few examples.

Fashion store: display down from 4.2s to 1.8s

Product images slimmed down and three non-essential external services removed: the main part of the page now shows in 1.8 seconds instead of 4.2.

FAQ

Frequent questions

What speed gains can I expect?

It varies a lot with the site's current state, but a 30-60% improvement in load time is common after applying the first quick fixes identified in the report.

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, repeatable conditions) and, when available, the data Google collects from your real visitors on mobile and desktop (the CrUX report).

Does a fast site really improve SEO?

Yes. Core Web Vitals — Google's official speed and display-stability measurements (LCP, INP, CLS) — count toward its rankings. The link between speed and rankings is detailed in the report.

What tools do you use for the audit?

Recognized speed measurement tools (Lighthouse, PageSpeed Insights, WebPageTest), server analysis tools, and a manual reading of the code — automated scores alone are never enough to build a real action plan.
