Error 404 page not found Google offers relevant web recommendations

"The '404 page error' is one of the unavoidable web link errors in website construction. Recently, American Google launched a new tool that provides an intelligent search box and the most relevant link address when a page error occurs.

This new tool offers a widget based on Javascript. When a 404 error occurs, Google will list a content and the most relevant other address to the 'missing' webpage on the webpage.

Website builders using this service need to register for a free Google Webmaster account and select the 'enhanced 404 page' option in the toolbar. Moreover, this service not only alleviates the disappointment of Internet users encountering a 'closed door', but also gains more search traffic through the freely placed webpage search box, making it a win-win cooperation."
