How the Schema Type Coverage Checker works
- List each page template with a representative URL.
- Compare against the schema types that page type would normally carry.
- Fix templates rather than pages — structured data belongs in the template so every page of that type gets it automatically.
FAQ
Which page types need structured data?
Those where a rich result exists for the content — products, recipes, events, articles, FAQs, local business pages. Adding markup where no rich result exists produces valid markup and no benefit.
Should I mark up every page?
No. Markup should describe what is genuinely on the page. Adding Product markup to a category listing or FAQ markup to a page with no questions is a policy violation, not thorough coverage.
Why audit by template rather than page?
Because structured data is generated by the template. A gap in one template affects every page using it, and fixing the template fixes them all at once.
