To help visitors find related content on your site, Site owners and webmasters create custom 404 pages. A custom 404 page can be easily created by WordPress Bloggers also. Earlier we used to design our 404 error pages. To the custom 404 page the webmasters can now add the Google 404 widget. The 404 widget Automatically display helpful suggestions based on the search term that resulted in 404 error page. Useful can be provided instead of error messages such as a search box for your site with appropriate search suggestions and alternatives to incorrect URLs are also provided.

Since the widget is an experimental feature, they currently don’t provide closest match, alternative URL and sitemap suggestions for all sites.
I did paste the code in my site and it worked very well on the 404 page. If you want to test it then just enter some page name say “http://www.technosamrat.com/test” and you can see it. I had even added the Random Post plug-in code so that the user can see some random posts.
