404 redirects are a very important part of SEO and everyday usability for your visitors. Do you want to click on a link and have an error message come up? Your visitors don’t either so every website should have a 404 redirect installed.
The biggest question I get is, do I have a 404 redirect installed already? 404 redirects are very simple to test for just type in your domain into your web browser with a page that doesn’t exist. Example: http://www.domainname.com/testfornopage.php
