The primary objective of link management is to call attention to hyperlinks that don’t work. There are many reasons why a URL might fail. For example: the resource being referenced doesn’t exist, the certs on an HTTPS connection is stale or invalid, firewall issues, timeouts, etc. Minimizing a website’s “links to nowhere” requires some up-front design work, as well as regular maintenance and monitoring. Pointing to a resource using a URL is more subtle than it might appear at first because it is tentatively impossible to check “all the links”; there’s simply no way to tell that every link the site can generate has been generated. For these reasons, the goal of link management is to find certain well-defined problems and to report them but because websites can be very large and various configuration parameters allow for some degree of tuning.
