• An internet link which doesn't lead to a page or site, probably because the server is down or the page has moved or no longer exists. Most search engines have techniques for removing such pages from their listings automatically, but as the internet continues to increase in size, it becomes more and more difficult for a search engine to check all the pages in the index regularly. Reporting of dead links helps to keep the indexes clean and accurate, and this can usually be done by submitting the dead link to the search engine.
