BreadcrumbList schema is a Schema.org type that declares the breadcrumb navigation hierarchy of a page (for example Home > Services > SEO). It is used by Google to display rich breadcrumb results and by AI agents to understand site hierarchy when navigating to deeper content.
A JSON-LD script with an itemListElement array. Each ListItem has position (integer starting at 1), name (the breadcrumb label) and item (the URL). Standard breadcrumb data, in machine-readable form.
AI agents map the breadcrumb hierarchy to understand which pages are children of which sections. This influences how the agent represents the brand's information architecture in its answers. It also unlocks Google rich breadcrumb display.
Add BreadcrumbList JSON-LD to every page below the homepage. Most CMSs can generate it from existing navigation data. Spacemen Digital adds BreadcrumbList schema as a standard AEO deliverable.
