| url listings or url-only listings | Noun phrase. These are the site listings that appear in Google with nothing more than a URL. Matt Cutts explained that they are uncrawled links that Google knows something about from inbound linkage.

Uncrawled links are not shown in Googles SafeSearch mode. Matt also discussed them here. |
