Many times Internet consumers see a 404 error message on the browser while opening a website. This means that the web page you are looking for (Page Not Found) is not found. It is more likely that the link you are trying to open is too old or there is a mistake in the typed link.
Many times this message appears even when the related page is removed. Its design is also different according to different browsers and websites.
Why 404 only appears … This number is recognized to show error in all search engines (eg Google, Yahoo, Bing) when web page is not found. Being a number code, engineers who design websites can easily improve it.
