Recommendation
Why it matters
BreadcrumbList markup shows the site hierarchy to agents. This checkpoint is retired. Old reports still show it.
How to fix it
Add BreadcrumbList JSON-LD that matches the visible breadcrumb.
-
Add a BreadcrumbList with one ListItem per level.
Verify
Run a new scan for this checkpoint:
isagentready results {domain} --checkpoint ia.breadcrumb-list
