Wikipedia:Redirect/Deletion reasons

You might want to delete a redirect if one or more of the following conditions is met:

1. The redirect page makes it unreasonably difficult for users to locate similarly named articles via the search engine. (see m:redirects in search results — proposed software changes for proposals to lessen this impact)
2. The redirect might cause confusion. For example, if "Adam B. Smith" was redirected to "Andrew B. Smith", because Andrew was accidentally called Adam in one source, this could cause confusion with the article on Adam Smith, so it should be deleted.
3. The redirect is offensive, such as "Joe Bloggs is a Loser" to "Joe Bloggs", unless "Joe Bloggs is a Loser" is discussed in the article.
4. The redirect makes no sense, such as redirecting [[Pink elephants painting daisies]] to love.
5. It is a cross-space redirect out of article space, such as one pointing into the User or Wikipedia namespace.
6. If the redirect is broken, meaning it redirects to an article that does not exist, it can be deleted immediately, though you should check that there is not an alternative place it could be appropriately redirected to first.

However, avoid deleting such redirects if:

1. They have a potentially useful page history. If the redirect was created by renaming a page with that name, and the page history just mentions the renaming, and for one of the reasons above you want to delete the page, copy the page history to the Talk page of the article it redirects to. The act of renaming is useful page history, and even more so if there has been discussion on the page name.
2. They would aid accidental linkingand make the creation of duplicate articles less likely, either by redirecting a plural to a singular, or by redirecting a misspelling to a correct spelling, or by redirecting a misnomer to a correct term, or by redirecting to a synonym, etc.
3. They aid searches on certain terms.
4. You risk breaking external or internal links by deleting the redirect. There is rarely a reason to delete historical CamelCase links.
5. Someone finds them useful. Hint: If someone says they find a redirect useful, they probably do. You might not find it useful — this is not because the other person is a liar, but because you browse Wikipedia in different ways.
6. The redirect is to a plural form (or to a singular).
7. The redirect is from an old article subpage which has been moved to a top-level page, particularly the various standard country subpages.

For example, redirecting Dubya to George W. Bush might be considered offensive, but the redirect aids accidental linking, makes the creation of duplicate articles less likely, and is useful to some people, so it should not be deleted.
