Structured data provides machine-readable information about a page and the entities it describes. The goal is accuracy and clarity. More schema is not automatically better schema.
What a schema audit checks
A useful audit checks syntax, appropriate Schema.org types, required or recommended properties for relevant search features, consistency with visible content, canonical entity identifiers and relationships between the organization, website, webpages, products or software.
Entity consistency matters
Stable @id values can connect references to the same entity across a graph. Names, URLs, logos and other factual attributes should remain consistent with the website and other authoritative profiles.
