Now Google is also providing a widget for webmasters to customize 404 error pages . This is especially handy when certain pages have been moved or removed but keep garnering precious traffic. The widget code is available at Google Webmasters Tools page. Of course, the 404 error widget is fully customizable and so can be easily and seamlessly integrated into your website. Microsoft had released a toolkit that performs the same function in June. Although it might sound like a trivial addition, it will help webmasters woo more users to their websites - or retain them to be more precise.
