Structured data only helps if it is valid and matches the page. Testing catches mistakes before they cost you rich results.
Tools
- Rich Results Test: checks whether a page is eligible for Google rich results.
- Schema Markup Validator: checks general schema.org validity.
- Search Console Enhancements reports: monitor structured data across the site.
Errors vs warnings
- Errors prevent eligibility; fix them.
- Warnings are optional fields; adding them may help.
Common mistakes
- Markup describing content not visible on the page.
- Wrong types or missing required properties.
- Prices and availability out of date.
- Self-serving review markup on your own business.
