Can CDN(Content Delivery Network) speed-up your website? If yes, then how?

If you have a website that plays very important role in your business or broadly on your professional career, then you are likely to be aware of the fact that many aspects are involved in building a good website. Some of these aspects are user-interface, performance, security and many more. All these factors equally play a vital role in formation of website. However, you can manage to have large traffic on your website only if your website is fast enough. If your website takes longer time to load then the chances are very that your website visitors will leave your website thus causing you a reduction in organic traffic at your website.

If your website is fairly fast then also there’s always a need of greater performance of website in this fast-pacing digital era. Speed is a prime factor to keep your visitors engaged on your website. You can speed up your website by making use of Content Delivery Network (CDN). Content Delivery Network basically helps to deliver static content of your website faster to the user. With the help of CDN you can efficiently speed up your web pages and thus increasing user engagement on your website.

Before getting into how CDN can speed up your website, its important to know what CDN is.

What is a Content Delivery Network (CDN)?

As the name suggest, Content Delivery Network (CDN) is a network/group of servers that are located close to the users. This group of servers basically work in conjunction to provide delivery of content faster to the end users. In simple terms, they reduce the load time of web pages content merely by reducing the distance between servers and the users.

With a CDN, information does not have to travel long distances between the server and the user. Instead of a single server, a CDN consists of a network of servers in various geographical locations. If someone visits a website, the nearest server location returns information. As a result, data flows more quickly. Likewise, content can be retrieved from a database by the server, as is the case with content management systems such as WordPress. Consequently, just one request causes your web server to be very busy.

How does CDN( Content Delivery Network ) work?

Let’s say there is no CDN involved with your website. Hence if a user request a web page, the request will be directly sent to the web browser which would give a response in the form of HTML pages, JavaScript files, images (or any type of media file), or any kind of assets need by the website.

You don’t substitute your web server for a CDN; the CDN acts as a middleman between the user and web server, caching your site’s content.  Points of presence (PoPs) are the endpoints of CDNs. Most CDN providers will have hundreds of them to distribute content. It is important to have a PoP physically near the user to reduce latency, called the “network edge”. CDNs try to optimize how much time users spend at the network edge without requiring them to make requests further into the network (and impacting your website).

CDNs of this kind are called origin pull CDNs or mirror CDNs. Note latency is nothing but a delay before transfer of data takes place. With a pull CDN, your website’s content is mirrored, so it is delivered with lower latency and improved caching. An origin push CDN, on the other hand, can take the place of some parts of your web server. Video streaming services and other large media are often hosted on push CDNs because they are difficult or nearly impossible to host on traditional web servers. CloudFront CDN, for example, can be used to push Amazon S3 images and videos, eliminating the requirement to host those files altogether.

How can CDN( Content Delivery Network ) enhance performance of your website?

By now we know that CDN helps speed up our website. there are ways in which CDN can primarily enhance performance of your website. here in this post we will examine such four ways in which CDN can significantly fasten your website.

Readers can now load pages more quickly due to CDN

Are you wondering what CDN does to speed up your website? here we have answer to it. A Content Delivery networks stores various types of content that your website needs and the moment user request a web page content, the CDN quickly deliver the content to the respective website. As the content is stored on the CDN itself, its easier for CDN to give requested content to the user in very short time.

CDN comes with an ability to store any format of content. For example, images, videos, stylesheets, excel sheets, audio files, .doc files, pdf, ppt, etc. In general, any file stored in the wp-content and wp-include folders of WordPress can be cached in a CDN. By utilizing a CDN, you can cut down the time it takes to request, retrieve and send data to users of your website. Seems pretty straightforward, doesn’t it? You should care about a faster website because it will boost your conversation rate. Speed increases of a few seconds can result in conversion increases of 14 percent!

Provides Cost-effective bandwidth

Through the method by which a CDN serves data to its users, it consumes less bandwidth overall than other methods of data delivery. Utilizing a CDN can help with the reduction of bandwidth costs if your hosting plan uses it.

Now the question arises, what kind of method used by CDN helps to reduce overall bandwidth costs of your website. As multiple servers are dedicated to take server the requested website content to the users, the rate of queries hitting your main webserver substantially decreases which results in reduction of bandwidth. This is how CDN help reduce bandwidth costs of your website. Make sure this is a viable option for your hosting plan. Plan prices can vary depending on bandwidth and some come with unlimited bandwidth options.

A better search engine optimization

CDNs can also help you rank higher and improve your search engine optimization in search engines due to faster loading speeds. Isn’t it great!?

In order to gain Google’s attention, websites should load quickly and easily crawled repeatedly. Google will be more easily able to identify changes in your content the more often it crawls your website. Your content will appear more frequently in search results with this fast-indexing turn-around. Faster indexing results in more widely available content. Every stage of the cycle begins with the health of your website. The framework and design of your website can have an effect on how one finds and consumes your content, as can some of the more technical aspects.

Additionally, CDNs provide an added level of security by reducing the possibility of attacks. Additionally, CDNs can be used with SSL certificates to provide yet another layer of security. In the case of search, security can also play a role in better indexing and ranking.

Adaptability to traffic spikes

Content owners dream of generating plenty of traffic and recognition for their websites and brands by creating content that goes viral. What if your dream comes true? What about a spike in traffic? Is your website prepared? That’s a crucial question upon which every website owner should ponder for a while. But you know what CDN can help you to resolve this issue too. Woah!

Since most website traffic is static – meaning it doesn’t change all the time – content can be delivered quickly and your servers will be under less strain due to a CDN. The chances of downtime are reduced when the server is under less load. CDNs are built to scale, so you can deal with sudden fluctuations in traffic (up or down) without being aware of the change because a website isn’t functioning anymore.

CDNs are reliable throughout all operational periods. A CDN retrieves information from a user’s nearest server when they access the website and in case that server isn’t available, it switches to the second closest. You can ensure the availability of your website at all times by using the automatic redundancy feature. Hence, the CDN can be helpful not only when traffic spikes, but also when a server connection somewhere along the chain is compromised. This is invisible to users because it happens so fast, but it makes a difference to the users because they won’t wait.

Final words

Your website will load faster for users with a content delivery network, you will lower your bandwidth costs, you will enhance your website’s search optimization, and you will be able to handle spikes in traffic. What else is need for a person who owns a website! This option is great for many webmasters and is very practical.
