What are HTTP status codes? HTTP status codes are response codes that web servers give on the internet. A server sends this message when the browser makes a request and it can or cannot gets fulfilled. This course help to identify the cause of the problem when a web page does not load properly. When user enters a URL on the browser, it sends a request to the website’s IP address to access the web page.

The server responds with status code embedded in the HTTP header which tells the browser the result of the request. HTTP 200 header code is sent back along with the content when everything is fine. But when something is wrong with the content or server, it gives back an error code.

Important status codes: General SEO codes

Now you need to learn http status codes for SEO. Even though there are a number of such codes, here are some most important codes for SEOs:

  • 200: OK/Success– This is the standard response which means the successful completion of a user’s request. In other words, when a client requests a server for any content, and it gets successfully delivered, the server replies with a 200 success message.
  • 301: Moved permanently– This is the preferred status code when redirecting content on your website. It is used when the requested URL has moved to a new location. The 301 redirect will navigate user to the right URL and also the link value of the old URL will transfer to the new one.
  • 302: Found– This means that the target URL has been found but has moved to a new location. You should only use a 302 redirect when you want the traffic to go to a new URL for a short while. 302 status code tells the search engines that the original URL will be used again so the link value is not transferred.
  • 307: Temporary redirect– A 307 is the original temporary redirect. It is usually for emergency redirects like when the server is down. This status response code signifies that the content of a webpage has temporarily moved to a new URL which is given by the location headers.

Important status codes: 4XX & 5XX codes

  • 403: Forbidden– This shows that even though the request was valid, the server will not respond to it. It tells the browser that the requested content is forbidden for the user. It might be because the user does not have the credentials to login. Pages with such status codes generally do not appear in the search results.
  • 404: Not found– It is one of the most visible and important status codes. When the server is unable to find the content, it returns a 404 status code. It is extremely important to fix these errors by using a redirect.
  • 410: Gone– This is similar as 404 but a 410 tells search engines that the requested content is deleted.
  • 500: Internal server error– This HTTP status code means that something went wrong at the code or database level. It usually means that something occurred which prevented the server from fulfilling the request.
  • 503: Service unavailable– A server usually sends 503 status codes when it cannot handle the request due to an overload. A user get to see this during planned server maintenance by a website owner.
