Important limits
This is a quick check, not Google's validator. It does not test eligibility for specific rich results. Confirm with Google's Rich Results Test and the Schema.org validator. Markup must match visible page content.
Frequently asked questions
Does schema improve rankings?
Not directly. It helps search engines understand pages and can make pages eligible for rich results.
Why does it say JSON-LD is invalid?
Usually a trailing comma, a missing quote or unescaped characters in the script.
