# Headless CMS: quality checks in the build

German title: Headless CMS: Qualitäts-Prüfungen im Build

> A build can check content before it goes live: required fields present, meta lengths met, internal links reachable, JSON-LD valid, every figure with a source. This lowers errors in operation. A quantified error reduction is not verified.

Manfred Sulzmann: “AEO belongs in the pipeline—not in rework. What the build does not check, chance publishes.”

## Facts

- **Purpose:** Find errors before publishing
- **Effect:** not quantified

## Possible checks (recommendation)

Build gatesCheck On failure
Required fields (title, description, summary, sources) Build fails
Title 30–60 and description 70–160 characters (project rule in meta.ts ) Warning
Internal links resolve, related starts with “/” or “https://” Build fails
JSON-LD is valid JSON and matches the visible text Build fails
Every figure in the text has a source link Warning

## Note

The lengths for title and description are project rules, not Google rules. The suitability of a particular CMS was not checked.
