BreadcrumbList
A schema.org type marking up the breadcrumb navigation on a page, displayed in search results as the URL hierarchy.
BreadcrumbList schema replaces the URL display in search results with the navigational breadcrumb (e.g., "Home > Services > HVAC > Plano"). It improves clickthrough by showing site context.
Implementation: add a BreadcrumbList to the page schema graph with each level as a ListItem with name and item URL.
