Why this matters
Structured data improves machine understanding and rich result eligibility only if it accurately represents the visible main content, avoiding misleading or hidden markups.
Hypothetical standard operating procedure
Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.
- Identify main visible content elements on the target page.
- Implement JSON-LD structured data reflecting only those elements, including organization, article, or breadcrumb schemas as appropriate.
- Use Google's Rich Results Test to validate structured data accuracy and completeness.
- Confirm via Google Search Console URL Inspection that Google detects the markup.
- Monitor rich result reports to ensure eligibility and absence of manual actions.
Watch for
Incorrect or hidden markup can trigger manual actions that remove rich result eligibility without affecting rankings.
Definition of done
Testing with Google's Rich Results Test shows no errors and markup corresponds precisely to visible content.
