mb, what distinguishes "a citation" from "a link"?

Anyone aware any G patents that elucidate the/a distinction - between a link that's "merely a link" and a "link that's citation"?

Are there references in any algo patent that reference a specific ranking power given to certain sites that grants those cites "citation (type) powers"? Something more or different than old fashioned PR/link-juice?
