Know How of HTTP Status Codes from SEO view-point

We all must have confronted the situation when different numbers start appearing on our screen while accessing a webpage. Some of the numbers are well-known; like 404 -Page Not found. But that’s not all. There are other numbers as well that exist not so frequently but make a dashing effect. In our routine we are never concerned about the origin of such figures because we know it is beyond our apprehension or we just request the IT guy to fix it.

Knowing what is in the numbers?

The numbers we often come across are not only of number in origin, basically it is the status code destined to appear when someone tries to access the malfunctioned web-service.

It can be simply understood with an example: Suppose a person is driving and witnesses an accident, then the first thing he would do – will call the ambulance by calling a specific number, say 101, or police by dialing 100. So, these numbers are short and are directed to work on emergency situations to serve a prompt response.

Similarly, the numbers appearing on our screen while accessing a malfunctioned web-service are specific codes designed to alert the user about the page. These codes are termed as – STATUS CODES and they display the short description about them.

Why are HTTP Status Codes used?

 Status Codes are the server responses in response to the clients system request made to the server. The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes to make the seamless services available.

The Status Codes work as a borderline asset element notifying a user about the possible blockades. Therefore, a web developer may put certain codes prior to making it live so that a user may not get confused.

Status Code Classification and Implementation

Internet Assigned Numbers Authority (IANA) maintains the HTTPS codes carrying different descriptions. The different segments of codes are classified as:

  • 1XX -> Informational codes.
  • 2XX-> Success Code
  • 3XX-> Redirection codes to redirect
  • 4XX-> Codes that fail to load on the client side
  • 5XX-> Codes that fail due to server error.

Some of the HTTP Status Codes important from SEO View-Point:

  • 200 : Code 200 refers to the success message about the request sent to the server. The best part is that it is visible only at the serve side.

  • 301 : Code 301 – known as permanent redirect it is well known in SEO for a way to reduce the number of redirects. The redirects slow down the speed and make the process lethargic for the users.

  • 302 : Code 302 – knows for performing temporary redirects.

  • 400 : Code 400 is well known to be raised as a banner for the BAD REQUEST.

  • 403 : Code 403 defines that the server has understood the user request but denied to perform the request. In SEO, 403 is used as a preventive measure to prevent crawlers from making requests.

  • 404 : Code 404 appears when the user clicks the broken link. At times 404 errors occur by mistake for the existing link due to the bug introduced by the developers on the web server.

  • Soft 404 : Soft 404 error occurs when a user accesses a deleted or removed page but never returns the user to HTTPS 404 status code, instead it returns 200 OK status code. Sometimes it occurs when page do not have any or very minimal content.

  • 410 : Code 410 appearing on a screen means to a user that the requested URL is permanently disabled or gone. SEO gets powerful with 410 as Google crawlers remove the web page that redirects with 410.

  • 500 : Code 500 stands for internal server error. It is defined as the state of a webpage that not only denies access but also cannot precisely pin-point the error.

  • 503 : Code 503 stands for service unavailable. From an SEO point of view the search engine knows about returning to the server only after the error gets fixed.

Status Codes are symbolic representations with powerful expressions which can affect the traffic. Thus, each time a developer has to carefully select the error codes to implement it and measure the user traffic accordingly.
