# BreadcrumbList positions, names or item URLs are invalid

`geo/breadcrumb-invalid` · severity **warn** · category AI search · detected by `void geo` and `void audit`

## 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
  ],
}
```
