I recently setup Schema.org BreadcrumbList
on my site. Check the validation here.
However, the 4th position item URL is not showing. I triple checked and the JSON-LD is validated. Any ideas?
I think it’s because the URL of the 4th item is the URL of the page you are checking.
If you copy-paste your source code (or simply change a random character somewhere) and check it again, Google’s tool will output the URL for the 4th item.
Nothing you have to change. Providing an item for the current page is fine according to Schema.org and also fine according to Google’s breadcrumbs guidelines:
The breadcrumb trail may include or omit a breadcrumb for the page on which it appears.
