Based on the Semantic method RDF, Content Labels are files that contain powerful metadata that enable search engines and browsers to provide more trust in search results.

Why Content Labels are useful
Visual badges provided by organisations such as Segala, VeriSign, GeoTrust and TRUSTe have limitied benefit. This is mainly because you only know when a Web site has a visual trustmark when you’ve already landed on it. Content Labels on the other hand are detectable by search engines and browsers which means users can find out which sites have Trustmarks without having to visit them. Furthermore, users can filter out anything that doesn’t contain a Content Label.

Content Labels act in a similar fashion to SSL Certificates. However, SSL Certificates are restricted to making claims about an entire Web site and they’re only used for security and identification purposes. Content Labels can be used to make assertions about an entire domain, or specific URIs. Furthermore, they can be used to make conformance claims to any standard or code of conduct.
