Breadcrumb Schema
In one sentence
Markup describing a page's position in the hierarchy, rendered as a path in the result instead of a raw URL.
Analogy Mental model
A floor plan in the listing, telling you which floor and which section of the building this shop occupies.
In practice What you actually do
BreadcrumbList, with itemListElement holding position, name and item for each level. The last crumb is the current page and needs no link. Generate it from the navigation the site actually uses, so the two cannot disagree.
Where people get burned Pitfalls
A breadcrumb whose middle level 404s is worse than no breadcrumb. It promises a route and then drops the visitor, costing trust on the one click you asked them to make.
