The following types of [[w:hyperlink|hyperlink]] can be distinguished:

# internal link in internal link style

# [[interwiki link]] in internal link style

# link in external link style

If no link label is specified, 1 and 2 are of the form [[ ''target'' ]] (with in case 2 ''target'' starting with a prefix) and 3 is of the form ''target'' or [ ''target'' ], where ''target'' is the [[w:URL|URL]] including <nowiki>"http://"</nowiki>. In case 3 no blank space is allowed in the URL. For MediaWiki pages the blank space can be replaced by an underscore, in general also %20 can be used; see also [[URLs#URLs in external links|URLs in external links]].

A label can be specified with in case 1 and 2 [[ ''target'' | ''label'' ]] and in case 3 [ ''target'' ''label'' ], with a blank space in between, see [[Help:Piped link]].

Link type 1 will be a link to the viewing page if the page exists at the time of loading or previewing of the referring page, otherwise to the edit page.

Reasons to use type 3 to link to an internal page include:

*linking to the edit page of an existing page

*the referring page is a [[template]] and the link target contains a template parameter

An example of the latter is in [[Template:Pd]]: although internal link style can be used for a calculation, e.g. [[google:200/7]], external link style like http://www.google.com/search?q=200/7 is needed when parameters are used; it is what we get with <nowiki>{{pd|200|7}}</nowiki>:

{{pd|200|7}}.
