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 BreadcrumbList structured 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.

Code Review

Review metadata generation, rendered HTML, structured data, and response headers related to Implement valid BreadcrumbList schema. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.
