Why You Need a CDN for Your Business Website [2025]

Nowadays, a business having a website is as crucial as having an office, shop, or telephone number.

Your website can also help you to build brand awareness online so that your customers can easily find you. 

For a business which is targeting customers in multiple geographical locations, they need to implement a Content Delivery Network or a CDN in their website.

The use of CDN for a business website has been recommended by web developers and marketers if that website is really content-heavy.

It is the best way to significantly improve your website’s loading speed, user experience and SEO. Also, many modern CDNs help in tackling issues related to website security.

Let’s see what a CDN is, how it works, and why you need one for your website.

What is a Content Delivery Network (CDN)

A CDN is a globally-distributed network for servers which enable faster delivery of website content to users around the world.

In other words, CDN helps in increasing the loading speed of your website and thereby provides seamless user experience for your website visitors irrespective of their location.

Without a CDN, the server that hosts your business website must respond to every single request from users. This results in significant traffic to the hosting server and thereby increases its load.

This will in turn increase the chances for server failure if the website traffic peaks or the server load is persistent.

When you implement CDN in your website, majority of the end user requests will be handled by the CDN and thereby offloading traffic from your hosting server.   

This will improve the overall web experience, thus benefitting both yourself (as a website owner) and your target audience.

According to Cisco, currently more than half of the global internet traffic is handled through CDNs.

How Does a CDN Works

Let’s use simple example to explain how a CDN works for your business website.

Consider that you run an online shopping store in India. You have built a great website and hosted it on a server, let’s say, located in Hyderabad.

When a user visits your website, everything (whether it is textual content, images, videos, etc) that loads on that website comes from this server in Hyderabad.

Let’s say a user in Abu Dhabi (UAE) is visiting your website. At this time, a request goes from the user’s mobile/desktop to your hosting server, where the website files are stored.

Since the distance between the user and the website hosting server is over thousands of miles apart, your website takes more time to load on the user’s device.

If your website takes more than 3 seconds to load, users will exit your website and never comes back to your site again.

This increases your site’s bounce rate and adversely impacts your online presence and thereby your sales.

Now let’s see what happens when you add a CDN along with your hosting server.

A CDN consists of a network of cache servers (also called edge servers) that are distributed in different parts of the world.

When the user accesses your website from Abu Dhabi, the cache server that is closer to the user’s location will respond to the request instead of the hosting server.

The CDN server will show a ‘cached’ version of your website to the user which reduces the time taken by the website to load on the user’s device significantly.

Instead of storing your whole website, a CDN server store only copies of website content temporarily and show it to users nearby its location.

This kind of arrangement makes your website loads faster, that means happy users and growing sales.

Keep in mind that using CDN is one way of optimizing website loading speed. You need look into other technical aspects of your website to make sure that the site loads faster.

Benefits of Using a CDN  

There are alluring benefits you can get by using a CDN, other than optimizing website speed.

• Improves website performance – CDN helps your hosting server respond to user requests (also manage traffic surges) more quickly and thereby improving your website’s performance.

• Protection from attacks – Many modern CDNs are well-suited in defending your website from denial-of-service (DoS) and distributed-denial-of-service (DDoS) attacks.

• Provides free SSL certificates – Nowadays, most CDN providers offer SSL certificates for websites and there are providers who offer it for free of charge.

• Highly redundant – Since CDNs consist of multiple servers spread out in different locations across the globe, they can offer high redundancy. If a CDN server goes down in particular location, other CDN servers can still deliver content to users in that location.

• Helps your website’s SEO – Google considers pagespeed as a ranking signal which means your fast loading website will rank for target keywords in Google search results.

Do all Business Websites Need CDN?

CDN is suitable for those businesses that target global audience and require a faster way to deliver website content.

Also, websites that are content-heavy require CDN to ensure uninterrupted content delivery. These websites include:

• Ecommerce stores
• Online news portals
• SaaS (on-demand/web-based software) applications
• Blogging sites
• Video streaming platforms
• E-learning platforms
• Real-estate search portals
• Job search portals
• Flight and hotel booking portals, and more.

To test the loading speed of your CDN-enabled website, you can use popular tools like GTMetrix, Pingdom, PageSpeed Insights, and Lighthouse (Chrome extension).
