The LINK element occurs within the HEAD element of an HTML document. It is used to indicate a relationship between the document and some other object. A document may have any number of LINK elements.

The LINK element is empty, but takes the same attributes as the anchor element .

Typical uses are to indicate authorship, related indexes and glossaries, older or more recent versions, etc. Links can indicate a static tree structure in which the document was authored by pointing to a "parent" and "next" and "previous" document, for example.

Servers may also allow links to be added by those who do not have the right to alter the body of a document.
