404Shield

404Shield is very easy to use and provides a clear overview of all broken, potentially broken, ignored, and redirected 404 links. The interface is intuitive, and makes it simple to create, edit, or disable redirects whenever needed. It also offers valuable insights into the performance of broken links (clicks and impressions). The app is most valuable for websites that have accumulated a significant number of 404 errors over time but it is also a good tool for ongoing website maintenance, allowing you to regularly monitor and address broken links before they affect user experience or search performance.
