Making 404 pages
Death chain appear, you do not pay attention to, it would happen, if you are not often focus on death chain, then you will give your own web site to find a shield, to give yourself stop stop. Like the master of the house of 404 pages, very lively and very humor, if is the user see also don't think this page not good, still can laugh, user experience will also better, standing in the search engine's point of view, the spider saw 404 state code, will also continue to crawl website, does not immediately ran away.
