How can I check for broken links on my web site?
As web sites move or disappear, links on other sites to those pages become out of date. To prevent this, web site administrators can add redirects that automatically take users to new pages that have replaced old ones, or they can provide the new, correct URL on the old page.
Site administrators often do not take these steps, however, and the responsibility falls on the linking sites' administrators to check their own links. A number of commercial and shareware programs are available that automatically test the validity of all links on a web page. These programs can also provide an automatic update when the URL of a web page changes.
