Integrity/Xenu Link Checker

Preventing users from reaching the dreaded 404 error while clicking through your site might seem unavoidable when you have sites with older content or hundreds of pages that would be tedious to click through. There are online link checkers that scan individual pages, but that can be just as time-consuming. Instead, turn to Integrity (Mac) or Xenu (PC). These free link checkers will scan site-wide for broken links,  so you can improve both the SEO and user experience on your site.
