For general info on '''redirects''' in [[wikipedia:MediaWiki|MediaWiki]], see [[wikipedia:meta:Help:Redirect|Wikipedia's Help on Redirects]] &mdash; part of the [[wikipedia:m:Help:Contents|MediaWiki User's Guide]]. This article discusses policy on the use and abuse of redirects on YPPedia, and is taken largely from [[Wikipedia:Wikipedia:Redirect|Wikipedia's policy]]. Other MediaWiki projects may have different approaches.

==How to make a redirect==

To redirect a page (1) to a different page (2), enter on the top of page 1:

'''<nowiki>#REDIRECT [[NAME OF PAGE 2]]</nowiki>'''

For example, to redirect the [{{SERVER}}{{localurl:Eieio Island|redirect=no}} Eieio Island] page to the [[Eieio Island (Ice)]] page, [{{SERVER}}{{localurl:Eieio Island|action=edit}} edit] the Eieio Island page and enter:

'''<nowiki>#REDIRECT [[Eieio Island (Ice)]]</nowiki>'''

It's possible to redirect a page to a section of an article, for example:

'''<nowiki>#REDIRECT [[Eieio Island (Ice)#History]]</nowiki>'''

Any text after the redirect will not be visible unless someone edits the page.

|Other capitalizations, to ensure that "Go" to a mixed-capitalization article title is case-insensitive
|{{R for alternate capitalization}}

Adding a redirect for '''mixed-capitalization article titles''' (e.g., Isle of Kent) allows "Go" to these articles to be case-insensitive. For example, without the redirect [[Isle of kent]] a "Go" for "Isle Of kent" or any capitalisation other than exactly 'Isle of Kent' would not find the article [[Isle of Kent]].

'''Why''': Articles whose titles contain mixed-capitalization words (not all initial caps, or not all lower case except the first word) are found via "Go" only by an exact case match. (Articles, including redirects, whose titles are either all initial caps or only first word capitalised are found via "Go" using a case-insensitive match.)

Note: "Go" related redirects are needed '''only if''' the article title has more than two words and words following the first have different capitalizations. They are not needed, for example, for proper names which are all initial caps.

Examples:
*Redirect [[Infierno De Los Diablos]] to [[Infierno De los Diablos]] is needed because the Go search is case-sensitive for mixed-caps titles.  Adding this redirect allows the article to be found when a user enters "infierno de los diablos" or "infierno de los Diablos" as a Go search.
*No redirect to [[Crimson Tide]] is needed because the "Go" command is case-insensitive for an article whose title is all initial caps. Any capitalisation (e.g. "criMson tiDe") entered as a "Go" will find the article.

* Avoiding broken links (see [[#Renamings and merges|below]])

* Minor but notable topics

[[Template:R with possibilities|Sub-topic redirects]] are often temporary, eventually being replaced by fully fledged articles on the sub-topic in question. Be conservative when creating sub-topic redirects &mdash; they can sometimes be counter-productive, because they disguise the absence of a proper article from editors. Sub-topic redirects should only be used where the main article has a section on the sub-topic. For example, on Wikipedia, [[Wikipedia:denial of service|denial of service]] has a section on distributed denial of service. Sub-topics should be '''boldfaced''' on their first appearance in the section, to indicate that they are in fact alternate titles or sub-titles.

In accordance with [[wikipedia:naming conventions (precision)]] it's best to have an article at a well-defined, unambiguous term, with redirects from looser colloquial terms, rather than vice versa.

=== Renamings and merges ===
We try to avoid broken links, because they annoy visitors. Therefore, if we change the layout of some section of YPPedia, or we merge two [[wikipedia:duplicate articles|duplicate articles]], we always leave redirects in the old location to point to the new location. Search engines and visitors will probably have linked to ''that'' page at ''that'' url. If the page is deleted, potential new visitors from search engines will be greeted with an edit window. The same is true for anyone who previously bookmarked ''that'' page, and so on. 

On a small scale, this applies to cases where we had duplicate articles on some subject, or lots of twisty little stubs on different aspects of the same overall subject.

== When should we delete a redirect? ==

To propose the deletion of a redirect, write in the article's talk page, and add a proposed deletion template if you feel it's warranted.  See the [[YPPedia:Deletion|deletion policy]] for details on how to nominate pages for deletion.  Please also see [[Wikipedia:Wikipedia:Redirect/DeletionReasons|this page]] on Wikipedia for reasons not to delete a redirect.


This isn't necessary if you just want to replace a redirect with an article, or change where it points: see [[Wikipedia:meta:Help:redirect#How do I change a redirect?|How do I change a redirect?]] on Wikipedia for instructions on how to do this. If you want to ''swap'' a redirect and an article, but are not able to move the article to the location of the redirect please ask on the article's talk page to request help from an [[YPPedia:Administrators|admin]] in doing that.

== What needs to be done on pages that are targets of redirects? ==
We follow the "[[Wikipedia:Guide to writing better articles#Principle of least astonishment|principle of least astonishment]]" &mdash; after following a redirect, the readers's first question is likely to be: "hang on ... I wanted to read about ''this''. Why has the link taken me to ''that''?". Make it clear to the reader that they ''have'' arrived in the right place.

Normally, we try to make sure that all "inbound redirects" are mentioned in the first couple of paragraphs of the article. For example:

* '''Longships''' were boats used by the Vikings... 
** [[Wikipedia:longship|longship]], redirect from [[Wikipedia:viking ship|viking ship]]
* '''Edvard Munch''' ([[Wikipedia:1863|1863]]&ndash;[[Wikipedia:1944|1944]]) was ... The broadest collection of his works is at on display at the Munch Museum at...
** [[Wikipedia:Edvard Munch|Edvard Munch]], redirect from [[Wikipedia:Munch Museum|Munch Museum]]

Don't cause a [[Wikipedia:secondary redirect|secondary redirect]].  They don't work like a primary redirect; same with tertiary redirects.

== Self-links, duplicate links ==
Avoid [[Wikipedia:Self link|self-links]], including self-links through redirects ("loop links"). Also, avoid having two links that go to the same place. These can confuse readers, and cause them to unnecessarily load the same page twice.
