Wikipedia:Red link

A red link, like this example, signifies that the linked-to page does not exist—it either never existed, or previously existed but has been deleted.

Add red links to articles to indicate that a page will be created soon or that an article should be created for the topic because the subject is notable and verifiable. Red links help Wikipedia grow. The creation of red links prevents new pages from being orphaned from the start. Good red links help Wikipedia—they encourage new contributors in useful directions, and remind us that Wikipedia is far from finished.

In general, a red link should remain in an article if there is a reasonable expectation that the article in question will eventually be created (either as its own article or as a redirect); remove red links if and only if Wikipedia should not have any coverage on the subject. It may be possible to turn the red link into a redirect to an article section where the subject is covered as part of a broader topic (see Notability – Whether to create standalone pages). But please do not "kill" red links by redirect because their red color (annoying to some readers) seems to scream for a fix. It is easy to turn any red link blue by creating a redirect, but valid red links exist for a reason, and they are the "buds" from which new Wikipedia articles grow. A valid red link should be left in place if the reader agrees on need for a future article with that best name, but does not want to provide one.

Articles should not contain red links to files, to templates, or to topics that do not warrant an article, such as a celebrity's romantic interest who is not notable in their own right. Red links should not routinely be made to every chapter in a book, or to all the people mentioned in an article. Red links should not be made to articles deleted because the topic was judged unencyclopedic or lacking notability. Red links may sometimes be created to articles deleted for some other reason. In addition, even if a page has been deleted because it does not meet Wikipedia's guidelines, you may make a red link to the term if you intend to write an article about an entirely different topic that happens to have the same title.

Creating red links
A red link appears whenever double square brackets  are placed around a word or phrase for which Wikipedia does not have an article, disambiguation page or redirect.

When to create red links
Create red links whenever a non-existent article with more information would help a reader understand the content of the article in which the red link will appear. An easy example is a technical term that merits a treatment beyond its dictionary definition, to help support its role for its existing context. A technical term could qualify because it is probably "notable" and should have that obvious title.

Before adding a red link, make sure that its subject does not already exist under a different page name. The topic may well be covered in a section of another article; it could even be buried in several paragraphs nearby. So it is the responsibility of the person who creates a red link to scan for the topic's coverage. The category links at the bottom of that page will link to virtually all related articles, and the search engine provides features for advanced queries that can pinpoint matching text anywhere on Wikipedia. Both search methods employ MediaWiki features crafted to find information on Wikipedia. They can help us build Wikipedia, red link by red link.

Take care when creating a red link that it has a valid title and that its subject meets notability guidelines for topics (including those for people (WP:BIO), web content (WP:WEB), businesses (WP:CORP), etc.).

After creating an article, (a) use What links here to find any red links that your new article turned blue, (b) check whether those links refer to the topic of your new article, and (c) change any links that refer to a different topic.

Avoiding creation of certain types of red links
Do not create red links to:
 * Articles that are unlikely to be created and retained on Wikipedia, including articles that do not comply with Wikipedia's naming conventions.
 * Categories that do not exist. Either the category should be created, or the non-existent category link should be removed or changed to one that already exists.
 * Templates that do not exist. Templates should only be added to a page if and after they have been created.
 * Wikipedia files that do not exist. Such red links are categorized for cleanup at Category:Articles with missing files.

Because they are useless as navigation aids, do not create red links in:
 * Templates such as, , , and , which are intended to direct readers to existing articles.
 * See also sections (see WP:NOTSEEALSO).
 * and hatnotes.
 * Redirect pages.

Red links may be used in navboxes which also contain links to existing articles, but they cannot be excessive. Editors who add excessive red links to navboxes are expected to actively work on building those articles, or the links may be removed from the template.

Red links are not to be shown on the Main Page.

To biographical articles
As with other topics, red links can be created to biographies of people who would likely meet Wikipedia's guidelines for notability. All the rules that apply to our biographies on living people equally apply to red-linked names.

Non-unique names
Redlinking a name which may not be unique bears the risk of the link eventually pointing to an article added later for a different person, company, or place with the same name. This is unlikely for, say, Thomas Howard, 14th Earl of Arundel, but very likely for football player Thomas Howard. Redlinking names of people who are not obviously notable also creates a link that may be unlikely to ever become blue. Adding detail to the link makes a misdirected link less likely (but not impossible); John Alexander Smith (physician) is better than John Smith. Simply redlinking names of people in an article, without detail, particularly if not obviously notable, should be avoided.

Checking incoming links is particularly important when creating new biography articles with article names that may not be unique. If some article has a redlink to that name but meaning a different person, the link will become blue but incorrect. This does happen in reality: for example, in 2012 a red link was placed in the article about the book to link to a future article about the book's author, Tom Mueller. In 2014 an article was created for a different Tom Mueller, a rocket scientist, without checking for existing incoming links. The red link in the Extra Virginity article thus became blue, but the link was to the wrong person. The error was not corrected until 2016, by renaming the link, which remained red, to Tom Mueller (writer). It might have been preferable to unlink the name; the writer may not be Wikipedia-notable, and even Tom Mueller (writer) is not guaranteed unique; in this particular case there is at least one more writer of that name, though without a Wikipedia article as of December 2023.

In disambiguation pages
Use of red links on disambiguation pages should be limited. The whole point of a disambiguation page is to help the reader arrive at the correct existing article from a choice of articles with similar titles. Since a red link is a link to a non-existent article, using red links in disambiguation pages is usually discouraged. Red links can be used in disambiguation pages if existing encyclopedic articles (i.e. not disambiguation pages, because disambiguation pages are not considered encyclopedic) have such red links.

Dealing with existing red links
In general, a red link should be allowed to remain in an article if it links to a term that could plausibly sustain an article, but for which there is no existing candidate article, or article section, under any name.

A red link to an article that will plausibly be created in the future should be "left alone rather than being created as a minimal stub article that has no useful information." An example of a plausible red link might be to Literacy in Somalia, since an article on Literacy in China exists, and country-specific articles on literacy are a likely area for future creation. However, it is better to leave this link red than to create a "placeholder stub" that says only "Literacy rates in Somalia are among the lowest in the world", with the sole purpose of turning the red link to blue. Editors should create stubs with a usable amount of content, or else not create the stub at all. Red links serve the purpose of notifying readers that a need exists in Wikipedia for the creation of a new article with at least minimal information content; the creation of minimalist marker stubs simply to get rid of a red link destroys this useful mechanism.

Likewise, a valid red link term like Literacy in Somalia should not be dealt with by removing the link brackets, simply to temporarily reduce the amount of red text in an article. However, red links to articles that have since been deleted should usually be unlinked.

An existing red link can indicate one or more of the following things:
 * A new article is needed. When a Wikipedian writes an article, it is common practice to link key topics pertinent to an understanding of the subject, even if those topics don't have an article on Wikipedia yet. Do not remove these red links. This has several applications:
 * From within an article, such a link prepares the article to be fully supported (not orphaned upon creation). At any time, a Wikipedian may independently write an article on the linked-to subject, and when this happens, there's already a link ready and waiting for it. The red link also gives readers the opportunity to click on it to create the needed article on the spot.
 * The red link may identify a need to create a redirect to another article, but only if that article comprehensively deals with the topic.
 * Some WikiProjects have bots that determine how many times a certain red link appears in Wikipedia. This is used to determine what articles are the most needed. Editors can also, after clicking on a red link, use the "what links here" function (although the article does not exist) to determine how many times the subject has been red-linked.
 * The link is broken and no longer leads to an article (perhaps because the underlying article was deleted). In such a case, the link usually needs to be removed or renamed to point to an existing article.
 * The link may have been made by someone who wasn't aware of what should and shouldn't be linked to within articles. Always evaluate whether or not a red link is pointing at a title that actually needs creation. See WP:Manual of Style/Linking.
 * The red link may be a typo—e.g., someone wanted to link to African elephant, but instead typed "African eelephant". In this case, try to figure out the intended article and fix the link. If it looks like a common misspelling, such as Scandanavia, you may want to create a redirect from that misspelling to the correct one, but you should still correct the misspelling even though it would no longer appear red.
 * Links in any of the various and  hatnotes, in, , , and  notes, as well as in "See also" sections, are meant to serve a navigational purpose. Red links are useless in these contexts; if possible they should be replaced by a functioning link, or else be removed.
 * Lists of "notable people" in an article, such as the "Notable alumni" section in an article on a university, tend to accrue red links, listing people of unverifiable notability. Such red links should be removed only if it's certain the subject would not qualify for an article on Wikipedia.

Red links and interlanguage links

 * The subject of the red link may be covered on another edition of Wikipedia. If such an article meets the English-language Wikipedia criteria and you are able to translate, then follow the procedures at WP:Translation; if not, use a link to the article in the other edition of Wikipedia instead of or next to a red link. Such links can be made manually or by using the interlanguage link template . For example
 * produces: Richard J. Youle until the name is added to English Wikipedia (as of June 2022 there is a German, but no English article);
 * links to the existing English page: Hanning Schröder.
 * If the English and foreign names are different: produces: Hooglede town hall
