BreadcrumbList positions, names or item URLs are invalid

geo/breadcrumb-invalidwarnvoid geoupdated

Why it matters

Breadcrumb rich results need ≥ 2 ListItems with positions starting at 1, a name, and absolute item URLs (the last item may omit item).

How to fix it

Build the list from the route segments with absolute URLs.

Example

ts
{
  '@type': 'BreadcrumbList',
  itemListElement: [
    { '@type': 'ListItem', position: 1, name: 'Blog', item: 'https://acme.example/blog' },
    { '@type': 'ListItem', position: 2, name: post.title }, // last item may omit item
  ],
}
