Rules and sources

Google Search Central, W3C WCAG 2.2, OWASP, SSL Labs and the RFCs provide the source for every rule. Each source becomes a check with a clear benchmark, a severity and an instruction in plain language. What we check is listed openly in the checklist, so you can look up every message.

Security and technology

The rules check certificate and connection, security headers, reachable backups and configuration files, redirects, caching and the technical structure of your website. Every rule is tested on real websites before it joins the scan. You get findings your host or developer can act on directly.

Updated 02.11.2026

Accessibility and content

axe rules based on WCAG 2.2, Lighthouse audits and the rules on German legal requirements make accessibility and clarity measurable. Added to that is the readability of each instruction: a sentence a business owner understands without prior knowledge and can pass to their agency. We check this for every new rule.
