Invalid Schema Types

What This Means

The page's structured data uses a "@type" value that is not a recognized schema.org type — either misspelled (e.g., "Artical" instead of "Article"), using a deprecated type that has been replaced, or using a custom or fictional type that schema.org does not define.

Why It Matters for SEO

Search engines validate "@type" against known schema.org types. An invalid type means the entire schema block may be treated as unknown or ignored. The entity type is the foundation of structured data — without a valid type, none of the properties within the block can be interpreted correctly.

What the Platform Checks

The platform checks each "@type" value in structured data blocks against the current schema.org type registry. Fires when an unrecognized type is found.

How to Fix It

• Check the correct type name at schema.org — types are case-sensitive and must match exactly.
• Common mistakes: "Webpage" → "WebPage"; "LocalBusiness" vs. more specific subtypes like "Restaurant" or "MedicalBusiness".
• If using a type that Google has deprecated: migrate to the current recommended type.
• Validate with Google's Rich Results Test after correcting the type.
