Dr. Link Check helps you track down broken and malicious links on your website. The tool crawls through the entire code of your site and gives each link a thorough examination. Is the URL properly formatted? Does the server respond in time? Is the SSL certificate valid? Does the server return an error code (404, 500, etc.)? Is the link pointing to a parked domain? Does the link appear on a blacklist for hosting malicious content? You can then drill down into the results and identify necessary changes to your website.
