It happens to the best of us - 404 errors. Whether it's because of a mistyped
URL, broken or truncated link within an email or because of content that has
been moved, end-users
often see these error pages - but there are ways to help visitors get the most
from this experience.
Google has added a section called "Enhance 404 pages" to its

visitors find what they are looking for by providing suggestions based on the
incorrect URL. For example, say a user visits a link which for whatever reason
gets cut off and a 404 page appears. Add the Custom 404 Error Page widget

Google will not only attempt to correct the URL but suggest a link to the parent
subdirectory, a sitemap webpage and provide a site search query suggestion and
search box. If you're interested, simply sign into
into your existing 404 page code.
