Dead link
From Free net encyclopedia
A dead link or broken link is a link on the world wide web that points to a webpage or server that is permanently unavailable. Dead links are commonplace on the Internet, but they are considered to be unprofessional.
The most common result of a dead link is a 404 error, which indicates that the page could not be found.
Dead links can also refer to URLs that point to sites unrelated to the content requested, e.g., a search for "Sports at ESPN.com" resulting in pornography or advertisements.
The process of links "spontaneously" changing to dead state is commonly called link rot.

Prevention and replacements
Dead links can be prevented using permalinks.
