How to use this library
The Schema Cleanup Field Notes library is designed as a working shelf, not a link directory. Start with ItemList Schema Contamination: Cleanup Checks for List Pages when the problem is still broad, then use FAQPage Schema Use Cases: When to Add or Omit FAQ JSON-LD or Breadcrumb Schema Failures: QA Checks for BreadcrumbList Drift to turn the finding into a decision record.
A good pass through this library should produce one artifact: a checklist result, scorecard, route map, or repair queue that another operator can review. When the artifact shows repeated unknowns, use the services route with concrete examples; when it resolves the issue, keep the page as a reference and move to the next bottleneck.
For backlink value, each page should be useful without a sales conversation: it must define the failure mode, show the fields to inspect, and leave the reader with a reusable operating object.
