Complete website diagnosis
Security, speed, mobile, search engines, e-mail, domain name, legal notice and GDPR: everything checked at once, with a clear report to save as PDF and pass on.
Première fois ? Le déroulé, pas à pas
- Tapez l'adresse du site (www.exemple.fr), appuyez sur « Lancer le diagnostic » et gardez la page ouverte pendant l'examen.
- En haut du rapport, lisez la note de A à E et la fiche du nom de domaine, puis la « Vue d'ensemble » : une note par thème.
- « Vos priorités » range les points à traiter du plus urgent au moins urgent, avec l'outil conseillé quand il en existe un.
- Appuyez sur « Enregistrer en PDF » puis, dans la fenêtre d'impression, choisissez « Enregistrer au format PDF » comme imprimante.
Conseils
- Pour ne voir que ce qui cloche, cochez « Afficher seulement les points à améliorer » au-dessus du détail par thème.
- Après une correction, utilisez « Refaire le diagnostic » : recharger simplement la page redonne l'ancien rapport pendant 5 minutes.
- Sur iPhone, pour obtenir le PDF : passez par le partage, puis « Imprimer », et pincez l'aperçu pour l'ouvrir en PDF.
- Pour transmettre le résultat, préférez le PDF, qui garde le rapport du jour : « Copier le lien du diagnostic » donne une adresse qui relance l'examen.

Report produced by ressources.online/outils/diagnostic/ · This diagnosis examines the home page and linked pages, without running scripts, from a server in Europe. It does not replace a legal audit or a full security audit.
Understand
Where has the health check gone?
It is now part of this diagnosis: the same A to E grade and the same technical checks, plus compliance (legal notice, privacy policy, trackers and cookie banner), image weight, the domain name, a priority list and a report to save as PDF.
How do I get the report as a PDF?
Click “Save as PDF”: your browser's print window opens. Choose “Save as PDF” (or “Microsoft Print to PDF”) as the printer. On iPhone, use Share then “Print”, and pinch the preview to open it as a PDF.
The report says a cookie banner is missing: is that certain?
The tool reads the page code without running it. If it finds Google Analytics, a Meta pixel or a standard YouTube video without a known consent tool, it flags it. A home-made banner may escape it, and a service loaded after consent is not always visible: treat the result as a starting point, not a legal verdict.
What happens to the address I type?
Our server visits the site to examine it, like a browser would, then checks the linked “Legal notice” and “Privacy policy” pages, reads the headers of the first images without downloading them, and asks the domain name registry what it publishes (Whois). The result is kept 5 minutes then deleted. To prevent abuse, a hashed fingerprint of your IP address is kept for at most one hour.
Where does the domain name information come from?
From the registry of the extension: Afnic for .fr, Verisign for .com, and so on. Our server queries it over RDAP, the successor to Whois, and only sends it the domain name. This is public data that anyone can look up. Registries hide the contact details of private individuals; those of companies, associations and public bodies are usually published. Not every extension tells everything: some give neither the expiry date nor the registrar.
