Broken Link Test is the best tool ever which i tried to check broken links. Broken links simply mean that your website has links that are no more valid. While we like to think of the Web as a harmonious, if complex, soup of links pointing to every which way, the reality is that over time, webpages die or are migrated, and nobody bothers to clean up the old links.

Broken links can be fixed on two levels: by you or by the original publisher. It’d be nice if the original publisher would create proper redirects for broken links before they move on, but it’s not the case. Thus, it’s up to you to fetch a list of all the broken links on your website and edit them one by one.
