Testing tools report two levels of problems. Errors mean the markup breaks a requirement and the page is not eligible for the related rich result. Warnings point to recommended properties that are missing but do not stop eligibility.

Fix in order
Resolve errors first, especially those affecting many pages. Treat warnings as optional: add a property only if you have accurate data for it.
Common causes
- A required property missing or empty
- Wrong value type, such as text where a number is expected
- Markup that does not match the visible page
- A syntax mistake in the JSON-LD
Common mistakes
Filling warnings with made-up values
Invented data is worse than a missing optional property.
