Abstract

RelNoFollow is an elemental microformat, one of several microformat open standards. By adding rel="nofollow" to a hyperlink, a page indicates that the destination of that hyperlink SHOULD NOT be afforded any additional weight or ranking by user agents which perform link analysis upon web pages (e.g. search engines). Typical use cases include links created by 3rd party commenters on blogs, or links the author wishes to point to, but avoid endorsing. For more specific endorsement (or lack thereof) semantics, see VoteLinks.
