Case study
Decobaie An audit before the mockup
Rebuilding a site without auditing it first means redrawing its faults in nicer colours. We started by measuring where Decobaie's visitors were getting lost, and only then designed, built and optimised.
The context
Decobaie manufactures bespoke aluminium and PVC window frames in the Paris region. It is a workshop trade with a long sales cycle: you compare, you request a quote, you wait for an installation slot.
The site existed, and it worked badly — without anyone knowing exactly where. That is not a detail: it is the starting point of the whole project.
A rebuild launched on an impression always produces the same outcome. You redraw the pages somebody disliked, you modernise the whole thing, and six months later visitors get lost in exactly the same place as before, only in newer scenery. The site is better looking; it does not convert any better.
What we produced
A rebuild in four stages, in this order — and the order IS the deliverable.
1. A UX audit, first
We analysed the existing experience to identify the navigation and usability problems: where journeys break, which pages lead nowhere, what demands needless effort.
It is the step most often skipped, because it produces nothing you can show. It is nevertheless the only one that stops you making the same mistakes in better handwriting.
2. A UI/UX design that answers the audit
The design was rethought — modern, professional, consistent with the brand, and fully responsive. Every decision answers a problem recorded at the previous stage, which gives the project something rare: visual choices you can justify by something other than taste.
3. A careful front-end build
The design was built in HTML5, CSS3 and JavaScript, with a reworked structure to ease navigation and speed the pages up. On a manufacturer’s site, speed is not a refinement: the visitor is comparing three suppliers, and the slowest one loses first.
4. SEO last, because it depends on everything else
The sector’s keywords were researched and the search optimisation done — technically as much as editorially. Leaving it until last is not an oversight: optimising a structure you are about to change means doing the work twice.
What it changes
Decobaie has a site where every decision traces back to a finding rather than a preference. That is what separates a rebuild from a refresh: the first one knows what it is fixing.
For a manufacturer selling a made-to-measure product to homeowners and trade customers alike, the point was never to charm. It was to stop losing the people who had already arrived.
