Hello, This is the same as a dead link. A broken link points to a webpage (or other document) that does not exist (anymore).
if your link have problem link it not working good if you click on link so link name will change and you got any type of error that means you link have problem
I think that name "broken link" is reserved to links that go nowhere and will often give 404. Fault is in your syntax for instance instead of www.google.com/webmasters you will have www.google.com/wemasters dead link is the one which goes to non-exisitng websita
