Broken links are those links which are mistakenly typed incomplete. These links are either not a link or a wrong link redirecting to error page. When I checked Broken links of my blogs I found several broken link on my blog and corrected it with the help of WordPress plugin known as Broken link checker.
This plugin automatically find all the broken links on the blog and display it when requested.
