I originally posted this on Monday, October 4, 2010 at 4:27pm on Google’s Facebook page. Since I have not seen any progress in this area, I am posting this again as a reminder to Google. If they are not going to pursue it, maybe Marissa Mayer might be interested in doing this at Yahoo!

Broken Link Resolver

Since Google Product Ideas does not feature Search, I’ll submit my idea here. One of the biggest unsolved problems on the World Wide Web is broken links. As the Google bot crawls the Web, it can detect whether the URLs of previously seen significant content have become stale (failure to connect or 404), and based on a heuristic content search determine where that page has moved.

Google could offer a new service that could answer the question: given this broken URL, tell me where the page has moved. Then, provide features in Google Chrome and a plug-in for Firefox that can make use of this service upon encountering a failure to connect or a 404. You could also provide an Apache httpd module that can use this service for handling 404s by automatically redirecting.
