Link Checker


Tool used to check for broken hyperlinks.


Link checking is one aspect of site management — the regular maintenance necessary to keep a site up-to-date.

A “broken hyperlink” does not correctly point to the intended destination page. The most common scenario involves a hyperlink “breaking” when the destination page is deleted or moved to another location.

Basic link checking involves testing for “404 – File Not Found” responses. Many link checkers also test for slow-loading pages, noting pages that fail to respond within a reasonable time limit.

While link checking tools eliminate a considerable amount of manual work, they do not completely eliminate the need for human review. For example, a page can return a valid response, but the content can change drastically — especially in the case of expired domains and objectionable content.
