When some of your webpages are removed or don’t exist, the webserver returns a 404 error. The page displayed when this error is returned is totally customizable, and it is strongly advised to do so.
Offering a webpage to your visitors with the same layout as the other pages of your site and with a high number of clickable links to other content will significantly decrease the bounce rate usually generated by an error page.
Tip: How to design your 404 page? It must use the same layout as the other pages. All the links to your categories should be there. You can add a mini sitemap that will help your visitor locate some content that might be interesting for him.
