A 404 page is an error page on a website that appears when you click or type a URL address which no longer exists or has been moved. When a visitor encounters a 404 File Not Found error on your site, chances are you’ll lose that visitor who took the time to visit your page through search engines. All your hard work to optimize your page to obtain visitors through search engines and third party links will go in vain.

This will minimize the loss of visitors and initiate more page views for your website.
