Quick Reference

A software tool which checks the correctness of hyperlinks in a Web site. One of the major problems faced by Webmasters who have to administer large sites is that the links in their Web documents become corrupted as the site grows and is modified. For example, a link may point to an external page in a site which has disappeared or to an internal page that has been deleted. Another problem is the reverse of this: that of pages, known as orphan pages, which are not linked to any other page. A link checker is a software utility which examines links and pages and provides a report on the extent of these problems. Such utilities can be stand-alone or can be incorporated into an existing tool such as an HTML editor. Link checkers are an example of a generic type of software known as site administration software. See also link checking site and link rot.
