# 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.
