Page Loading Time, CDN and SEO
The loading time of a website is very crucial when it comes to website’s SEO performance.
How well your website will rank on Google depends a lot on how quick is the loading time. CDN or content delivery network is a network that is used to primarily increase the website loading time in different parts of the world.
By diving deep into this article, you will understand this term in detail and know what its role in SEO is?
Let us understand this with an example-
A website which is created in the US will load faster within the country than other parts of the world. What we are trying to say is, the website loading time increases as you go far from the original position of the website’s server. Now, why does that happen?
Latency is a factor that decides the website loading speed in different parts of the world.

Latency is time required for a server to respond to a request.

What is the role of CDN in decreasing latency?
Why does a website load slowly in other parts of the world is compared to the location where it originated? It’s because the client and server are getting far from each other, as we increase our distance.
The website’s server starts taking a lot of time to respond when we request it from other parts of the world except the original location.
A content delivery network or CDN works on the concept mentioned above, and it shortens the distance between client and server irrespective of the demographic location, and this helps in lessening the website loading time.
There are two types of file on your website; static and dynamic.
As we had discussed earlier, static files are those who don’t need any development based on certain rules, whereas dynamic files fall have the specific rules for different users and locations. HTML, Javascript, CSS, and image files are an example of static files.
These files will stay the same as they are for every user out there in the world.
Now CDN makes these static files available on various data centers across the world which helps in loading a website super fast.
