404 error is a very common website error message that states that the webpage you are looking for is not being found or mehjud.
Some websites display custom 404 error pages, which look very similar to the same site as other pages. Other websites simply display the default error message text of the web server, which typically starts with ” Not Found “.
Regardless of its appearance, a 404 error means that the server is active and running simultaneously, while the webpage or the path or path of that webpage is not valid.
Now the question arises, why then it is called a ” 404 error ” and not just a ” Missing Webpage Error ?”
The answer is that 404 is an error code that is generated by the web server when it cannot find the webpage it is searching for.
This error code is well understood by search engines which helps these search engine crawlers not to index such bad URLs.
404 errors can be easily read through web scripts and website monitoring tools, which helps webmasters find these broken links and fix them simultaneously.
There are also other common web server codes such as 200 , which means a searched webpage has been found. The second one is 301 , which represents that a file has been moved to a new location . Like 404 errors , these status messages cannot be seen directly by users, but they are used by search engines and website monitoring software.
