If the results have surprised or convinced you, let’s move on. Please excuse me for a few technical licenses to better explain the advantages and operation of a CDN.
What is a CDN?
A CDN is a content delivery network. It is based on a series of servers spread across the globe that contain a version of the static content (images, CSS, JavaScript) of our website.
Thus, when a person visits our page, they receive information from the server that is geographically closest to it, thus obtaining a faster response when sending the data, since we reduce distances and avoid intermediate jumps.
In addition to reducing the load on your server, using a CDN will provide users around the world with faster loading times and therefore a better user experience globally.
Every CDN service is different, and there are many, both free and paid.
They will be faster or not, depending on which regions you are in. This all depends on the number of servers they have and where they are located.
In the following image we see a diagram of an example CDN.
In this case, the service has good coverage in China and the USA, but it has only one server in Europe and none in Spain, which makes it not a good CDN for a website if our target audience is Spanish or European.
What is clear is that a website will be faster when visited from the USA or Australia, if it is within that CDN, than if it is on a Spanish Hosting.
What is a CDN used for?
So far it is clear, just by definition, that a CDN canada email list must improve the response and loading speed of our website from other points on the planet.
Let’s now suppose that we put our website on a CDN with a server, now yes, in Spain.
If our usual Hosting was already located strategic marketing is not just about advertising in affect SEO Spain, what advantage is there for my Spanish visitors?
In other words, is it worth using a CDN if the speed at which my website loads for a potential visitor in China is of no concern to us?
The answer is YES… and one reason is cascading loading .
To put it simply, we need to know that maldivian lads our browser accepts a limited number of simultaneous HTTP transfers from a server.
For this example, we have disabled caching to force the browser to download everything necessary from the server in order to render affect SEO the page.
When we enter the address in our browser, the server sends the first byte of information (TTFB) 724 ms later. As we can see, from then on, there are processes that cannot be started until some of them finish.
