A canonical link element is an HTML element that helps webmasters prevent duplicate content issues in search engine optimization by specifying the "canonical" or "preferred" version of a web page. It is described in RFC 6596, which went live in April 2012.
When visiting a web page, the referrer or referring page is the URL of the previous web page from which a link was followed.

This is treated like a 301 permanent redirect by Google, allowing transfer of PageRank to the target page. [16] This is an example of a simple HTML document that uses this technique:
When using the WikEd source editor, selectable from Preferences > Gadgets > Editing, there is a "Wiki link" button (typically the first button on the bottom row). When editing, if some text is highlighted, clicking the Wiki link button will enclose it in double brackets, i.e., Wikilink it. If, however, some text is highlighted that includes one ...
