Backlinks that point to nonexistent pages?

[xnavigator]

Hello guys,

what do u think of this kind of back link?

Do they still pass pr?
Or if they point to nonexistent pages they are useless?

Thanks a lot

Yes, if the URL in the backlink is 404, then there's no where for PageRank to flow to. PageRank is calculated for a page, not a domain.

But you could 301 redirect the dead URL to a relevant one. That would help.
