See also: Wikipedia:Redirect

A redirect is a page with no content other than:

#REDIRECT [[pagename]]

Where pagename is the article or page to redirect to. For example, on Wikipedia, the page "Ancient forest" has only the text:

#REDIRECT [[Old growth forest]]

See Ancient forest for how this appears when a reader goes to the "Ancient forest" article. The "Old growth forest" page should appear from this link. A small notice of the redirect is also displayed (under the top title) to indicate you arrived here indirectly. If you click the link in the notice which reads:

(Redirected from Ancient forest)

you can see (and edit) the redirection page itself.

How it appears to the user

If the link is to an existing page in the same project, going to the redirect (by means of a link, the URL, or the Go button) results in the new page, just like following the link, except that the browser shows the original URL, and the new page shows a redirection message below the title. (To get the canonical URL in your browser's address bar, click the article tab.)

For example, if somebody goes to: Help:Redirection, then they will end up at this page instead, and the top of the page will look like:

Help:Redirect

From Meta

(Redirected from Help:Redirection)

(etc)

If the link is to a non-existing page in the same project, or to a page in another project, one simply arrives at the redirect page.

When a page called for inclusion is a redirect page, the redirect target is included instead, with the same parameters, without any redirect message. Again, a double redirect does not work.

Restrictions

As a simple way to avoid problems with infinite recursion, if the redirect target is another redirect page, the second redirect is not applied.

A redirect target cannot depend on a variable, template, or parser function. When attempting this, the restriction does not become apparent in the preview (see also the section below on the rendering of a redirect page), but only after saving.

Purposes of a redirect

  • Allow access in the case that a pagename is provided:
    • which is an alternative term for the subject
    • which is a term for a subtopic (in this case one may use a redirect to a section)
    • which uses alternative capitalization and hyphenation
    • which uses alternative spelling
    • which has a common misspelling
  • Provide a way of conveniently going to a page (shortcut)
  • Keep links to a page active after it has been moved (even if internal links are updated, this still applies for external links)

Special purposes

  • Conveniently linking indirectly to a page, without the need for a Piped link. However, a piped link is in some respects even better than relying on a redirect, see Comparison with piped link.
  • Allowing a link title independent of the final link target; one creates a page whose name is the desired link title, and which redirects to the desired target page. See e.g. w:Template:Ft, containing [[30.48 cm|ft]], with the page w:30.48 cm redirecting to w:Foot (unit of length). The link title "30.48 cm" informs in the hover box about the unit "ft" even without following the link to the article about this unit. See also hover box for another technique with a similar result.

The move tool

When a page is renamed/moved with the Renaming (moving) a page function, a redirect is automatically created from the old to the new name, and also one for the corresponding talk page.

If the new page name is occupied by a redirect with only one edit in its history, it is replaced by the page being moved. If the redirect has more than one history entry, then it must either be deleted by an administrator or moved to another name. This move will leave behind a new redirect with no edit history, which can then be replaced by the desired page move. It might be desirable to delete the moved redirect.

Creating a redirect

If you're creating a new redirect, start a new page, write #REDIRECT [[pagename]] (or #redirect [[pagename]]) at the top of the page, where pagename is the name of the target page. Here is an example. If you're replacing an existing page with a redirect, for example after merging a duplicate page, go to the page, edit it, and replace the existing text with #REDIRECT [[pagename]].

Extra text after the #REDIRECT command and link is ignored. It is rendered in preview only, see [1] and [2]. Category-tags are not ignored. If a category is set, the redirect-page is listed in the category it belongs to, see e.g. Template:Ddd. When following the link from the category page to the redirect page then as usual the redirect is applied.

The page will not redirect if there is anything on the page before the redirect. Also, there must be no spaces between the # and the REDIRECT. An edit summary is automatically provided, with the text according to MediaWiki:Autoredircomment, but only if no edit summary is supplied (as opposed to the automatic edit summary in section editing, which can be supplemented by the user).

After you create a redirect, you get sent to a page with the string "&redirect=no" in the URL. Thus the just created redirect page is shown, not the page to which it redirects. To see your redirect working, use your address bar to delete that part of the URL. Alternatively, create a link on another page to your redirect, and then follow that link.

When creating new redirects, bear in mind that creating too many redirects can clutter up the search results page, which can hinder users. Also, don't spend too much time creating redirects - often it's more important to spend time improving the quality of the target page. A piped link is another way to make a link to a page with a name which does not occur in the first page.

A code like %70 in a redirect disables it, although the link works from the redirect page.

Changing a redirect

Click on a link to the redirect page. Then look for the "(redirected from source page)" link at the top of the page you've been redirected to. Click on the "source page" link. You will be taken to a page looking something like:

Pagename
From project name ...

#REDIRECT [[''target page'' ]]

Then click Edit this page. You can then either change the target of the redirect or replace the redirect with a brand new page.

Another way to do the same thing: Go to the target page, and click "What links here". This will show you all the back-links from that page, including redirects. To change a redirect, click on it, and then click on Edit this page as above.

The redirect page shows the canonical form of the target, unlike its preview page, which renders the link in the usual way, compare [3] with the preview of [4].

Deleting a redirect

Administrators can delete redirects in the same way as any other page. There may be project-specific guidelines on when this is appropriate.

Interwiki redirects and redirects to special pages

Interwiki redirects and redirects to special pages have been disabled, try e.g. Help:Interwiki redirect demo and Help:Redirect to special page demo.

Use direct interwiki links (or direct links to Special pages) without redirect, or a soft redirect (non-automatic): a page with "See ...", e.g. w:Wikipedia:Enhanced Recent Changes.

A redirect to an anchor

One can redirect to an anchor, in particular a section. Help:Section linking and redirects is an example and its target also provides more info.

Section redirects work from r18220 onwards. See bugzilla:218. On older versions of MediaWiki, you will be redirected to [[definitions]] but you will not be sent to the #G anchor.

A redirect to a page in the image or category namespace

On Meta and Wikipedia a redirect to an image page or to a category shows the editable text only. To get the full page after being redirected, use the link "Image", or "Category", respectively.

On Commons a redirect to a category gives the full page, but not the subcategories and pages in the redirect page (if that is also a category).

Images linking to a page

There are ways to make an image link to a specified page, some which work especially well on Mediawiki sites that support embedding external images. For possibilities see Help:Navigational image.

Detecting links to redirects

Specifying a very high value as threshold in the stub feature allows indication of links having a redirect as target: while other links to the main namespace are all marked as stub, they are not (however, links to other namespaces look the same, they are also not marked as stub). This can be useful for clean-up work involving bypassing redirects.

One may want to change the setting only temporarily, if one normally uses the stub feature in the regular way, and/or because section linking does not work on "stubs", unless external link style is used.

Redirect and/or link to non-existing page

When B is a subtopic of A, and B does not have its own page, or at least not with additional info, there are the following possibilities:

  1. redirect B to A, use the backlink to go from A to B (disadvantage: not very inviting to create a new content page B; inconvenient if A has many backlinks)
  2. link A to B ("red link") as invitation or preparation for creating page B; use the backlink to go from B to A (disadvantage: not obvious for newbie, much less convenient than automatic redirect, especially if B has many backlinks)
  3. both (indirect self-link on A) - after applying the link from A through B back to A, use the link in the redirect message to go from A to B (for detecting a redirect see above; the method is useful for temporary use during clean-up, but not for permanent use; also, there is no distinction between a redirect back, and an onward redirect) (disadvantage, as far as not yet mentioned: not obvious for newbie)
  4. ditto but with a soft redirect from B to A, i.e. a page only containing something like "See [[A]]"; one can see at A that B is very short using the stub feature (disadvantages: a soft redirect is non-standard; people who do not know about its reason may change it in a regular redirect; is a little less convenient than automatic redirect; requires stub feature setting)
  5. B is a redirect, link from A to B with "redirect=no", or link to B's edit page, e.g. Template and start page Template, respectively.

In the 3rd and 4th case, especially if A has a list of links to pages B, one can mark the links with more info, e.g. by bolding, and explain the marking.

Rendering of the redirect page

The redirect page shows the content of MediaWiki:Redirectpagesub (by default the text "Redirect page") with a bent arrow, followed by the link. This link shows the canonical form of the target.

This does not apply in the preview of a redirect page: this ignores the special meaning of the redirect syntax, so it shows a one-item numbered list, with the link rendered as an ordinary link. Compare [5] with the preview of its edit page [6].
