Ensure your schema qualifies for Google rich results — FAQ boxes, stars, prices.
Validate that all required schema.org properties are present and correctly formatted.

Pinpoint exactly which part of your JSON-LD has errors with line-by-line feedback.
Validate before deploying to avoid sending Google broken structured data.
