Implement valid BreadcrumbList schema
Breadcrumbs help search engines understand your site's structure and often appear in search results, improving navigation and click-through rates.
Quick Reference
- Add
BreadcrumbListstructured data only when the page has a visible, meaningful breadcrumb trail - Ensure the breadcrumb path matches the visible trail and the site's logical hierarchy
- Use JSON-LD to mark up each item in the breadcrumb trail correctly
Check
Verify that the page contains valid BreadcrumbList structured data matching the visible breadcrumbs.
Fix
Implement a JSON-LD script that defines each level of the page's hierarchy using ListItem properties.
Explain
Explain how breadcrumb schema replaces URLs in search results with a more readable navigation path.
