Do you know what is CDN? and how beneficial it is for a website? If you are a blogger or want to make your career in the field of blogging, then understanding CDN becomes very important for you.
CDN is very important to increase the speed of any website. If you have heard the name CDN somewhere before but you do not know enough about it, then there is nothing to worry about,
I will give you complete information about CDN with examples in simple words. So that all the doubts related to your CDN should be cleared. So let’s start this article.
What is CDN?
The full form of CDN is the Content Delivery Network.
Definition of CDN – It is a medium that copies the content of a website to the server of a different location so that the content is delivered to the user of a different location from the server of a different location and the speed of the website increases. CDN is mainly used to increase the speed of the website.
This then became the definition of CDN, as many websites are there in the Internet world, the data of every website is stored on a server.
From where the data is served to the users of different locations. Serving data from the same server to the user of a different location causes a load on the server.
But if CDN is used in the website, then the data is served from different servers, due to which there is no load on the main server and the speed of the website is also not down.
Example of CDN
Let us understand with an example, suppose the data of our site is stored on the server in India, if visitors come to our website from America or any other country, then it will take time to reach the data, and the loading timing of the website will increase.
Now if we have connected our website to CDN, then a copy of the content of our website will also be made on the US server.
Similarly, from whichever country the traffic will come to our website, a copy of our website will be created on the servers of all those locations.
Due to this, the data of our site will be accessible to everyone quickly and there will be no load on our main server. That is, the speed of our website will increase.
Let us understand it better through an example. As YouTube’s main server is in America, if you are running YouTube from India, then it will take time for you to access data from America, and it will take so much time to load any video so that you do not play YouTube.
To overcome this problem, YouTube used CDN, due to which a copy of YouTube’s data was also made on India’s server. So now you will get the data from the servers of India, from which the video gets loaded within seconds.
Benefits of CDN for Website
There are many advantages of CDN for a website, some of which are mentioned below –
1. Increases page speed

2. Improves Google Ranking
Website Speed is a very big Ranking Factor that cannot be ignored. If a user reaches your website and your website takes a lot of time to load, then it has a negative effect on ranking.
But using CDN increases website speed. Increasing the speed of the website also improves the ranking of the website because Google also wants the website to load in less time.
3. Prevents Server Crash

But by using CDN, the problem of Server crashes can be avoided because using CDN does not load on the Main Server.
The content of your website is served by different servers at different locations. Due to this, the risk of server crashes is removed.
