It is easy to make mistakes coding web page links. And when you make mistakes both humans using your sites, and the authority of the page you were trying to link to are diminished. And, of course, sites are not static, so links that might have been fine at one time become bad links later if a page being linked to moves or is deleted.
Do you use any tools to find links that are outdated and need to be updated on your sites? If you do, share with us how you go about finding and updating links on your websites.
