Browsing webpages and quick responses of it or the faster the page loads, the better the conversions become. No one would prefer to wait for ten seconds to load a web page. Parallelly, no organization or a blogger would want to see their customers moving away from them just because of the slowness of their website, more the time a page takes to load, higher the possibility of losing a customer. So more visitors  = more business. Its very important to online shopping websites.

To avoid this concern, Bloggers or organizations use Content delivery networks to optimize the performance of the websites, and they are having to reap benefits by deploying a CDN.

Let’s talk about what is a CDN, how it works and what is the impact it has on SEO ( Search Engine Optimization)

What is a CDN

CDN represents, Content Delivery Network. So what is a CDN? To put it easiest way, CDN enables fast transmission of the content from websites to users based on their geographical location within a quick time. These content may include images, JavaScripts, HTML pages, and any other assets on a website.

So, CDN is the reason why you get access to a webpage instantly without having to wait for it to Load for six, seven seconds. Researchers explain that 40% of users abandon a website that consumes more than three seconds to load. Hence, Using a CDN is becoming a necessity these days to cater to the audience to close the sales efficiently.

How CDN works

CDN is a set of (network) computers that enable fast deliveries of website contents. When you are log in to a website, you tend to put a little bit of stress over the server, which provides you the service. If that website is not using a content delivery network service and having a load of visitors, it bound to become slow and unresponsive, which would result in losing people from that particular website. As I said, CDN helps you avoid it.

What CDN does is, it identifies the content of your website such as images, videos and distribute them to the closest server location of the people who are looking for it.

There are several service providers such as Amazon, Rackspace, Akamai, to name a few. These service providers have their servers all around the world. What it does is, when a user looks for content, it caches the content into those servers and distribute them instead of utilizing your server.

For example, assuming that your website is located and hosted by a data server in London, and you have visitors all around the world. Your server would find no difficulty serving the people of the UK, but without a CDN, your data has to drift more than 10,000 miles to cater to your visitors in Brisbane, Australia. No matter how advanced the technology is, this distance bound to hamper the loading time of your website.

It is essential to deploy a CDN if you are eager to run a successful business. If not, you will be going to lose customers and the sale.
