Benefits of Using a CDN

As a game-changing virtual landscape with over 3 billion users worldwide, the Internet has given many businesses a unique opportunity to reach millions of customers around the globe. Here most of the advantages are for those businesses that deliver reliable web performances, desirable user experience, security, and availability. All these factors and many others are only possible by using the CDN service. Content Delivery Networks are the best assets to provide optimal and secure web performance. They are a must-have for every universal business.  But why are CDNs so pervasive? What are the significant benefits of using a CDN? Here are the top 10 benefits of using a CDN.

Why Should You Use a CDN?

To explore the advantages of using a CDN, you must understand the CDN concept well. If you do not know much about the Content Delivery Network or CDN, we encourage you to read our articles that describe “What is CDN and how does a CDN Work?” and “Everything You Need to Know About CDN Architecture”.
Today thousands of universally known brands and websites use CDNs mainly because they serve global audiences and want to deliver their content fast. Since web pages are overgrowing, the Internet is getting faster, and media are becoming more and more involved in our daily lives, using a CDN is a must. A CDN provides the quick transfer of assets needed for loading Internet content such as images, videos, java scripts, pages, stylesheets, and HTML. CDN can help you combat the slow load times that happen to many websites due to web page sizes’ rapid growth.
CDNs contain a significant portion of the world’s web traffic. They are an essential tool to successfully conduct business online because they are built to handle the demands of massive amounts of data. CDNs can make the Internet better, deliver media faster, and enable great user experiences. Read more below about “What are the benefits of using a CDN?” besides the performance factors.

What Are the Benefits of Using a CDN?

Although CDNs improve the end-user experience, in the end, their primary clients are websites and online platform owners. Let us have a look at the advantages of using a CDN.


Most definitely, the best advantage of using a CDN is improved speed. As mentioned in the CDN Architecture article, a CDN serves static content from a server node that is closest to the requesting user. Once the speed is improved, the user experience will become better. Since CDNs are placed close to the user, it will be possible to reduce latency, especially when the distance that the content needs to travel is shorter. That is why a CDN can make a website load faster. It has been proven that visitors are more inclined to click away from a slow-loading website. CDN will reduce the bounce rate and increase the number of times visitors spend on the website. A faster website means more visitors.

Website Uptime

CDNs will reduce the load on the host, which will result in consistent speed. If all the site’s resources are housed on the main shared/private server, there will be inconsistent speed or failure during the high traffic periods. It means websites can get slow and sometimes break down completely during traffic spikes for the added loads. CDNs can help handle the spikes smoothly. With a CDN, the network is optimized to handle high traffic with improved efficiency. It will reduce the chances of any crash.

Bandwidth Consumption

News is the traditional web hosting is not enough and capable of bearing heavy loads these days for websites and applications. Instead of directly pulling data from the origin server, it is always better to expect the same function from CDNs’ edge servers. This will help reduce computation and deliver high-quality media in a shorter span. Ultimately, it will hold the resources for a shorter duration and minimize bandwidth consumption. Reducing the bandwidth consumption will also reduce the origin server’s load, which results in lower expenses.


A CDN will eliminate the need to invest in costly foreign hosting, infrastructure, and separate service to reduce the costs. A cloud CDN offers powerful platforms to handle all the separate operations working across different locations for reasonable prices. CDN is affordable for both giants and smaller businesses. It can be chosen based on budget and requirements. Since CDNs bear almost more than 60% of the total website load, they can be cheaper in the long run. The load sharing with the origin server results in lower bandwidth consumption.

SEO Boost

Google considers page loading speed as one of its signals used for ranking the pages in SERPs. The faster a website is, the better the chances of achieving the top ranks in the SERPs. Google indexes images more than other content on the web pages. With a CDN, image utilization is possible. These images can be hosted on a CDN and loaded on the web page with the fastest speed. It is clear that a page’s speed, data transmission security, and user experience can contribute to a better result in search engine ranks.


Along with delivering content quickly, CDNs can offer valuable analytical information to discover trends that can reveal an online business’s strengths and weaknesses and lead to advertising sales. Content Delivery Networks can deliver real-time load statistics, show active regions, optimize capacity, indicate the popular assets, and report viewing details. Each nod will have reliable data about its generated traffic. Since the usage logs are deactivated, these details are essential. CDNs provide any information that a developer needs to optimize the website. Constant reporting will improve the performance, which results in a better and high user experience. This will reflect on sales and conversion rate.


When a website experiences a large flow of traffic, CDNs can come in handy. Offering an extensive network of servers will ensure that all the resources are variable and scalable. DDoS attacks happen when attackers hold the server’s resources by pushing a heavy load to it. As a result, a traditional web server will crash and take down the website. CDN edge servers will bear most of the load on the website and keep it up and running. Any attack will have to go through the edge servers, and that is the power of decentralization of data in CDN architecture.
DDoS attacks can cause economic losses and impact the reputation and image of a brand. So as DDoS attacks are on the rise, new ways of internet security are being developed. All of them helped increase the advantage of using CDN, as cloud security adds another layer of protection. These methods, like the ArvanCloud security solution, is designed to stop an attack before reaching the datacenter, and nothing can compromise it.

Data Integrity

Most website owners want to use the latest tools to render their content. Updating when assets are one way to be always up to date, and a CDN integration will help reserve integrity if any change is made to the assets. For instance, if the CSS or JavaScript files are updated on a CDN, the changes will be instant mirror across various servers on the network, preserving consistency and data integrity.

Geographical Barrier

In a world of modern technologies with increasing mobility and app-driven Internet, users want access to services anywhere and anytime. CDNs have globally distributed servers that can help users experience a website like they are next to the host. If a business targets users from a particular location, it should check the CDN provider’s coverage map to determine where it can get the best benefits to reach many users. Some CDN providers have clear advantages in some regions based on the network setup.

Business Advancement

All the benefits mentioned above eventually add up to the overall user experience of a website. CDNs ensure a high data threshold for a network so that many users can access it at the same time without delays. By handling high traffic flow, CDNs allow people worldwide to access a website simultaneously. From speed, SEO benefits, security, analytics, and everything ultimately leads to a better conversion rate. CDN providers can set up new PoPs, which will help expand clients into new territory without sacrificing user experience and service quality.

Final Thought: You Should Be Using a CDN

In this article, we discuss, “what are the benefits of using a CDN?” To conclude, a CDN provides many performance benefits for a website. It will distribute bandwidth across multiple nods and reduce the load on the main host. CDN offers a smooth user experience. CDN is a necessity if you prefer flawless service and performance. If you have an improving approach and want to be successful, you should consider CDN as a part of the optimization tools. Be sure to select a CDN provider that fulfils all your requirements.
