To know & understand about the HTTP response code, first, we need to understand what they are. So, without wasting a bit of time. Let’s dig in to know what they are.
What are HTTP status codes?
In a simple technical language, the HTTP status code responds from the server towards the browser’s request. To understand it much better, let’s take an example. When a user visits any website, their browser sends a request to the site’s server, and after that, the server responds to the browser’s request with a three-digit code which is known as the HTTP status code.
These status codes represent the Internet equivalent of a conversation between the browser and the server. The reason why all this happens is because of the communication. They communicate with each other regarding whether things between the two are okay, touch and go, or whether something is wrong inside.
Knowing what HTTP response codes help people understand the status of codes and help them use them as well. It also helps the user diagnose site errors quickly to minimize downtime on their website.
Moreover, these codes are also used to help search engines and people who use or have access to your website. A 301 redirect HTTP response code, for example, will tell bots and people that a page has moved somewhere else permanently.
The first digit of each HTTP response status code begins with one of five numbers, which follows from 1 to 5. For example, they may be expressed as 1xx or 5xx to indicate status codes in that range. Every range here encompasses a different class of server response.
The Five most important Common HTTP status code classes are: –
1xxs – Informational responses: For the server to think through the request.
2xxs – Success: Your request was successfully completed, and the server gave the browser the expected response you are waiting for.
3xxs – Redirection: This means you got redirected to somewhere else & the request that was received is a redirection of some kind that must need to happen.
4xxs – Client errors: This is the most common type of HTTP code response where the page not found comes out as a response.
It tells users the site or page couldn’t be reached. (The request was completed, but the page isn’t valid. This is an error on the website’s side of the conversation and often appears when a page doesn’t exist on the site.)
5xxs – Server errors: This is another most common type of HTTP response code, which means failure. Here, the client made a valid request, but the server failed to complete the request because of some errors.
Some of the Most Common HTTP Response Status Code
HTTP Status Code 200 – OK
This is the most ideal & the most common HTTP status code that many people usually see on their normal, everyday, properly functioning page. Visitors, bots, and link equity often pass through these linked pages like a sweep. When you see this code, you don’t need to do anything. You can happily go about that in your day & can secure the knowledge that everything is just like it should be.
HTTP Status Code 301 – Permanent Redirect
It is another most showed response code on the webpage that redirects. A 301 redirect should only be utilized when one URL needs to be redirected to another permanently.
It also means that visitors and bots that land on that page will be passed to the new URL. In addition, link equity, the power transmitted by all those hard-earned links to your content, is also passed to the new URL through a 301 redirect.
HTTP Status Code 302 – Temporary Redirect
Not entirely, but some part of the 302 redirect code is similar to the 301. In 302, visitors and bots are passed to the new page, but not permanently. When you ask an expert, he will often recommend not to use 302 redirects for permanent changes.
Using 302 is only for the search engine crawlers to treat the redirect as temporary, meaning that it may not pass along the link equity that the magical 301 does.
HTTP Status Code 404 – Not Found
Basically, code 404 means the server does not find the file or page that the browser is requesting. However, it doesn’t indicate whether the missing page or resource is missing permanently or only temporarily. If you want an example of it, you can see with your own eyes by typing a URL that doesn’t exist on the internet. It’s almost like hitting a brick wall that isn’t there as well. The thing that makes it more common is that every site has some pages that return 404 status codes usually.
Another common misconception about this is that it’s an SEO best practice to simply 301 redirect pages that return a 404 status code to the homepage. But in my opinion, it is a bad idea for most cases because it can fool users that the webpage they are trying to access doesn’t exist.
HTTP Status Code 410 – Gone
This is one of the most common as well as the most typical response codes of HTTP. It is like 404, but 410 is more permanent. It means that the page is gone & there is no chance it can ever be available for the user.
Moreover, the page is no longer available on the server, and no forwarding address has been set up for that page. Any links on your site pointing towards a 410 page are because of the sending bots and visitors to a dead resource. So, if you see them in any case, remove references or links.
HTTP Status Code 500 – Internal Server Error
The other most common type of HTTP response code is 500. This response doesn’t show a problem being with the pages missing, or they are not found. Apart from that, this status code indicates a problem is with the server, not with the pages. It is a classic server error that affects access to your site for a limited amount of time until the problem gets resolved.
HTTP Status Code 503 – Service Unavailable
Another same common type of code as 500 is 503. It means that the server is totally unavailable. In this response, everyone is asked to come back later on the webpage. This could be due to temporarily overloading the server or maintenance of the server.
This code ensures that the search engines know to come back soon because the page or site will only be down for a short time.
