FAQ
Questions about the audit service
The answers that apply across the service, plus a separate FAQ section each for website operators, agencies and partners.
General
What exactly does the audit service audit?
Publicly reachable websites in these audit areas: accessibility (WCAG 2.2 A/AA), SEO, GEO (AI visibility), Core Web Vitals, GDPR & cookies, indexing & technology, responsive and software currency. Each audit area is assessed separately and receives its own seal.
How can I verify a seal?
Every seal links to its public verification page at /zertifikat/<audit ID>. It shows domain, audit area, score, audit date, validity and status; revoked or expired seals remain listed there too.
Is this an official certificate?
No. The audit is a documented technical examination according to published audit regulations, neither an administrative act nor legal advice. Its strength is verifiability.
Why should I trust this seal?
Because you can check it yourself: every seal is publicly verifiable, the procedure is documented, and the measurement core is checked against a test page with known defects. An empty audit counts as an error with us, never as a pass.
Does the auditor respect the robots.txt of my website?
Yes. Addresses your robots.txt blocks for the auditor (product token EuidPruefservice) are not requested, even if they are listed in your sitemap. Such an exclusion is explicitly reported in the result and not shown as missing content. If the home page itself is blocked, no audit takes place at all. That matters because a needs analysis requires no proof of domain ownership.
What does the rule-set version on a seal mean?
It names the version of the rules the audit was made against. Rules change; what counts as met today may be tightened tomorrow. Without this information an old seal could not be placed: nobody would know what it passed against. Together with audit date and validity, the rule-set version is what makes a seal verifiable at all.
What data does the audit service store about an audited website?
The requested addresses, the measurements and findings derived from them, the audit scope and the billing data of the audit. What is stored is what is needed to trace a result; a seal whose basis can no longer be inspected would be worthless. What is processed in detail is in the privacy policy.
A seal on someone else’s website looks wrong to me. What can I do?
Open the verification page the seal links to. If the domain named there does not match the website you see it on, or if it is expired or revoked, then the website carries a seal it is not entitled to. Report the address and the audit ID to us; this path is the reason every seal is publicly verifiable.
Who is behind the audit service?
The complete operator details are in the imprint. As long as details are missing there, the page shows the gap openly instead of filling it with placeholders; an imprint with invented data would be a false statement about a real person, and an audit service that starts that way has missed its own point.
What is audited in each audit area
One page per audit area with every single check and its explanation; the lists come from the measurement core itself.

The audit levels
Which level is ordered decides whether a seal can be created at all and whether a person has judged alongside.
Needs analysis
No seal, report without proof character · without auditor time
Free analysis for agencies and organisations to determine the need for action of a project. Full findings report, but explicitly without a seal and without proof character.
Pre-audit
Seal possible · without auditor time
Fully automated measurement of all criteria a machine can decide. Fast, affordable and repeatable at will, without human judgement.
Gold standard
Seal possible · with human judgement
Automated measurement plus human judgement on the criteria no machine can decide. The full proof, with a named auditor taking responsibility.
One exception is written down explicitly: Accessibility cannot get a seal in the pre-audit. A substantial share of the WCAG criteria cannot be decided by a machine; an automatic accessibility seal would be exactly the illusion this service stands against.
