Schema markup helps search engines understand page entities and relationships. It should describe what is already visible and true on the page.

Useful schema types for many websites

  • Organization for brand identity.
  • WebSite for the site entity.
  • BreadcrumbList for page hierarchy.
  • Article for blog posts and guides.
  • LocalBusiness when the business has accurate local details.

What to avoid

Reading is useful, but your website data is what matters. Open the matching tool and test it while the problem is fresh.

Do not add review, FAQ, service or local business markup unless it accurately matches the visible page. Structured data that makes unsupported claims can create quality problems even when the JSON-LD validates syntactically.

How to add schema safely

Pick the most specific relevant schema type, include accurate recommended properties and test the page after publishing. Schema is a clarity layer, not a substitute for useful content.

Open the schema markup checker guide or create markup with the schema generator.
