Search engine discover the content by following the links from pages to pages. For this purpose Googlebots visits the site and collect all the information about any new uploaded post, old post, broken links, incoming links to site or even any relevant link. After collecting all this information Googlebot report back to Google where after determine the quality, information further processed for search indexing. But sometimes when you have made a website and the delete it, now when Googlebot will visit your site and crawl but it will not found your site. Now when a visitor will search this site, which is removed and not found by Googlebot, then search engine will respond with error “404” or “File Not Found”. Following may other replies by search engine you will receive:
- 404 Error
- File Not Found
- HTTP 404
- Error 404 Not Found
- 404 Page Not Found
- The requested URL was not found on this Server
- 404 File or Director Not Found
These were some words which we receive from search engine when search engine can’t find our requested website/URL address.
Common Causes of “404 Error”
There are many reasons due to which search engines could not found an error and reply with 404 errors or file not found. There are many reasons due to which this error occur.
- When the searched URL doesn’t exists.
- When the searched URL deleted.
- When required URL not available for the time being.
- When required URL renamed without redirecting from old URL to a new page.
- When searched URL moved from another server.
- When you written a wrong URL then also occur 404.
- When Web service extension or MIME type is disabled.
- When virtual directory is mapped to the root of a drive on another server.
- If Generative Rule on URL changed.
- Wrong Spell in Backlinks
- If required URL is prevented by DNS Setting
- If required URL is password-protected from Googlebot Access
- If required URL is not in Google Index.
These were some causes due to which 404 errors occur and search engine could not find the enquired URL. It may be due to your own mistakes if you have typed a wrong URL or you wrong spelled any URL in address bar. Sometime it occur due to mistake of site owner or blogger because if he wrong spelling of URL in Google index. But sometimes due to one or two digit spelling mistakes, Search engine always shows the relevant results and the URL which are likely near to the enquired URL regarding their spell. I mean if their spellings are same, there is just difference of one or two digits, and then search engine will show those similar URL also.
How to Fix 404 Errors?
In case if required URL is really not existing then you can’t remove this error. Although there are two solutions to remove or fix 404 errors on the reason if URL is working, moved on any other location, renamed without redirecting from Old URL to new URL or any other reason excepting it has been deleted or not exist. One is provided by Microsoft Support while second I suggested.

Solution by Microsoft
To remove this error, first verify that required URL exists or not. Use the IIS Microsoft Management Console (MMC) snap-in to determine where the file requested must exist in the IIS computer’s file system. This is mostly significant if the Web site uses a virtual directory (VDIR). A VDIR is a directory that is not contained in the home directory of the Web site, but appears to client browser as though it does. This virtual directory must be mapped to a subfolder on a drive or reference the files by name. For example, assume that the URL that caused the 404 error is
and the IIS snap-in shows that for Microsoft.Com Web site, the /Test/ directory is actually a virtual directory that maps to the location of c:\Information on the IIS computer. This means that you must verify that the File1.htm file is located in the c:\Information directory (and that the file name is spelled correctly).
IIS6 Dynamic Content: A 404.2 entry in the W3C Extended Log file is recorded when a Web Extension is not enabled. Use the IIS Microsoft Management Console (MMC) snap-in to enable the appropriate Web extension. Default Web Extensions include: ASP, ASP.net, Server-Side Includes, WebDAV publishing, FrontPage Server Extensions, Common Gateway Interface (CGI). Custom extensions must be added and explicitly enabled. See the IIS 6.0 Help File for more information. IIS6 Static Content: A 404.3 entry in the W3C Extended Log file is recorded when an extension is not mapped to a known extension in the MIME Map property. Use the IIS Microsoft Management Console (MMC) snap-in to configure the appropriate extension in the MIME Map. See the IIS 6.0 Help file for more information.
