Template:Dead link/sandbox
 | This is the template sandbox page for Template:Dead link (diff). See also the companion subpage for test cases. |
 | This template is used on approximately 322,000 pages, or roughly 1% of all pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
Usage
[edit]This template is used to mark dead links, either within a paragraph or within a reference citation. Marking dead links signals to editors and to WP:Link rot bots that this link needs to be replaced with an archive link.
Before considering whether to use the {{dead link}} template it is often useful to make a search for an archive copy of the dead link and thereby avoid using the tag altogether. All {{cite xxx}} templates have the facility for adding |archive-date= and |archive-url= parameters for linking to an archive copy. Non-{{cite xxx}} citations can use {{webarchive}}.
Using {{Dead link}} will place a note by the URL and add the article to one of the Category:Articles with dead external links categories.
Append this template directly after the link (after the link code's terminating ] if you are using wikitext), or, if you are using a {{cite xxx}} template, directly after the {{cite xxx}} transclusion (not inside it), but inside the reference, if any, i.e. before the </ref>, in all cases leaving the original link intact:
<ref>{{cite web|url=http://www.example.org|title=The Example Website|access-date=22 September 2012}}{{Dead link|date=November 2024}}</ref>
For bare links, leave a space after the end of the URL and the template:
* http://www.example.org {{Dead link|date=November 2024}}
Otherwise automated tools can have trouble determining where the URL ends, because it will ambiguously contain url-encoding and wiki-encoding mixed together.
Not following these syntax rules might hinder detection by automated tools. If the citation contains multiple URLs (e.g. chapter-url and url) in a template, and only one is broken, you can use wiki comments like <!-- <your hidden explanation here> --> to explain which one is broken.
If the article uses clickable footnotes, then this template should be placed just before the </ref> that contains the dead link. The notice will then correctly appear in the reference section instead of in the body of the text, and so WP:Link rot bots can properly find and fix the link.
If you are placing this template inside a <ref> </ref> reference, do not leave any substitution template such as {{subst:CURRENTMONTHNAME}} or {{subst:CURRENTYEAR}}, because substitutions fail inside ref tags.
Avoid using this template when the reference is fully adequate without the link. In this case, simply remove the link. For example, if a {{cite journal}} template is used with a DOI, remove the |url= parameter.
- Common form (with current date)
{{Dead link|date=November 2024}}
Optional parameters
[edit]url- Provides a history of the linked page via the Wayback Machine. Set only if history actually exists, as otherwise it is misleading to users and editors.
date- The date parameter consists of the full English name of the current month with initial capital, a space, and the year, not full dates; e.g., "January 2013", but not "jan13". Any deviation from these two rules will result in an "invalid date parameter" error.
bot- Bot accounts specify the
|bot=parameter as a sign that the tag was added by an automated process. Set asbot=<bot name>. fix-attempted- Set this to "yes" if you have tried unsuccessfully to find an archived copy, or a copy with a different URL. This will put the page in Category:Articles with permanently dead external links, and the annotation will be rendered as "[permanent dead link]" instead of just "[dead link]". Note that this currently will occur for any value supplied, including "no", so if a fix was not attempted, simply leave this parameter off, or set it to be blank. Also note that if a page cannot be found in the Internet Archive (Wayback Machine), often a live copy can be found via a web search for the full title, in quotes, on the original website, or on the Internet at large. Alternatively, you can use {{Permanent dead link}} as a shortcut to using this parameter.
Notes:
- The date-substitution template may be used to automatically generate the date, e.g.,
{{Dead link|{{subst:DATE}}}}. See Help:Substitution for more information. - The
date=parameter need not be added by the editor: if not entered, a bot will soon add it.

Caveats
[edit]- Avoid using free/bare links without a separator (e.g.
http://www.example.org/{{Permanent dead link}}). Frequently software is unable to differentiate the URL from the template, and will interpret the template as a literal part of the URL. Add square brackets or a space separating the template from the URL. Correct:http://www.example.org/ {{Permanent dead link}}and Correct:[http://www.example.org/]{{Permanent dead link}} - Avoid complicated formatting. Nesting inside another template is not generally supported.
- Avoid using [ ] { | } < > characters between the end of the external link and {{Permanent dead link}}, as they are often used to format text.
