Error 404 – how to fix it?

Servers have a way to communicate for informing about queries’ status. They do that through different HTTP response status codes, like the error 404.

Once servers receive a query, they start a process to answer the client with the required website. Using different codes, they indicate if it was successfully completed or not, if there was an error and its type, etc. There are five categories of responses.

  • 1, informational responses.
  • 2, successful responses.
  • 3, redirects.
  • 4, client errors.
  • 5, server errors. 

What does error 404 means?

Error 404 is an HTTP response status code that belongs to the category of “client errors”. It means “not found”. 

  • The server can not find the resource that was requested.
  • When it’s about the browser, the meaning is URL is not found.
  • In Application programming interfaces (APIs), the endpoint is valid, but the resource does not exist.

Error 404 very frequently appears online. The web holds plenty of dead or broken links and exactly those that obtain such response status code when clicked.

This code does not give the user information to know if the resource is missing permanently or temporarily. 

Error 404 format

It commonly appears like:

  • Status 404 Not Found 
  • 404 Not Found Error 
  • The requested URL was not found on this server
  • 404 File or Directory Not Found
  • 404 Page Not Found
  • HTTP 404 Not Found

How to fix error 404?

Redirect. Use the response code 301 to redirect browsers. Through this code, you point that content requested is available now with another URL. 

Track broken links (internal and external) on your website and fix them. There are tools to find them, or you can do it manually, but it will take longer. 

Fix internally broken links by correcting typos. Mistakes while writing URLs’ lead to broken links. Moving links to their right places also helps. If you put an article in the wrong category, you can produce a broken link. 

If you include links from different websites (external) and re-located or deleted, this generates broken links on the other site. Delete them or replace them with another site (link) that offers similar info.

Restore cleared pages. People can keep looking for a page you already deleted. If it is possible and it has a sense for your business, restore it. Whenever you delete pages from your site, redirect users to similar content pages to avoid broken links. 

Customize Error 404 for being less annoying. Besides website’s owners, we are Internet users. So we all know how disappointing it is to request a page and not to receive it. If the “Error 404” appears after long waiting, the bad feeling gets worse. For users, not to leave your website definitely, better give the 404 page a nicer look and make it helpful for them. You can explain on it the steps to follow for reaching you later. You can apologize and offer a nice and concerned ‘face’. 

For sure, you have seen designs including cute animals with the popular “oops”. A cute doggie saying, “Oops, I may chewed up the power cord,” can be forgiven easily, don’t you think so? Others prefer fun messages, meme style. Shit happens, and we know that, but a bit of humor can make the difference with your clients not to be so angry.

Be free and creative to design your own custom 404 page.
