Keep markup aligned with visible content
Accurate annotations matter more than adding every possible property.
Describe what visitors can see
Bing’s webmaster guidelines require structured markup to accurately reflect visible content. A technically well-formed rating, offer or event can still be misleading if the underlying page does not support it.
Use human review alongside rules
After running a check, compare the report with the page. Verify names, prices, availability, dates and the relationships between entities. Remove obsolete annotations when the content changes.
Know the boundary
CheckMySchema does not infer whether a claim is true, assess policy compliance or predict ranking. Those judgments remain outside deterministic vocabulary checks. Consult Bing’s current guidelines before deploying a template across a site.
