This audit framework is designed for three situations:
- International businesses entering Germany — you have an existing site and are adding a German-language version, subdirectory, or ccTLD (e.g., .de domain).
- Established German-language sites with stalled rankings — you rank on Google.de but growth has plateaued and you suspect technical or content-level issues.
- Sites that recently lost visibility on Google.de — a traffic drop that correlates with a Google core update, a site migration, or a CMS change.
This guide is not a general on-page checklist. It focuses specifically on the diagnostic layer — identifying which category of problem is responsible for underperformance, so you can prioritise fixes correctly rather than addressing symptoms.
You don't need to be a developer to work through most of these checks. A basic familiarity with Google Search Console, the ability to inspect page source code, and access to a crawl tool (Screaming Frog, Sitebulb, or similar) will cover the majority of the diagnostic steps below.
If your site operates in a regulated German industry — financial services, healthcare, legal — additional compliance considerations apply beyond the scope of this guide. The GDPR and Datenschutz compliance page covers those requirements separately.
