Website speed, or if you prefer a more technical term, web page loading speed is an important SEO factor. It’s also the main constituent of user experience. The attention span and patience levels in modern online content consumers are pretty low. If your website is not loading fast enough, you risk losing that precious traffic. Content Delivery Network can significantly speed up a website.

CDN providers deliver services able to accelerate any website despite the location of the server it’s hosted on. Best CDN utilizes file cashing and does it on servers across the world. The website visitors don’t have to download the content from servers across the planet. Instead, they get the content from the nearest server.

How to choose the right CDN provider

Looking at the best CDNs list can help you narrow down your options. You should keep in mind though that the best content delivery network is not at the same time the right content delivery network provider for you. As you could see, all providers are different. They have points of presence in different cities, countries, and continents, use different technologies and architecture, and implement a variety of security solutions.

You also have to make a decision whether to go with a free CDN or a paid one. The bottom line is – choosing the right provider is not easy. Apart from knowing the offer inside and out, you have to know how to pair CDN features with your unique business, website, and visitors’ needs. Here are the most important things to check when choosing the right CDN provider.

The locations of points of presence

You know your visitors the best. Use website traffic analytics to discover geolocation your visitors are coming from. The right CDN companies should have PoPs in those locations or at least nearby.

Network connectivity

Network connectivity is measured by good response times, no packet losses, and low latency. Either use a free trial or dig a little deeper through customer reviews to learn about the CDN provider’s network connectivity profile.

Wait times vs DNS response times

To achieve a lightning-fast speed, you need fast wait times and fast DNS response times. However, some CDN providers have complex DNS setup due to questionable practices and fast-growing networks. It can significantly slow down DNS response times. Always make sure that CDN can serve your content faster than your original server, or so-called Origin.

Delivery speed of small files and larger payload

Some providers are better at serving small files, while others are better at serving larger payloads. The top CDN providers are good at both. Test booth uses before you make your final decision.

Cache hit/miss ratio

Last but not least, take a close look at the cache hit/miss ratio. If your CDN has to go back to the origin to get the content too often, you won’t benefit from using a CDN. The bigger the ratio, the better. Some of the best CDN providers have it above 95%.

Best of the best

If choosing the right CDN sounds too complicated for you, don’t worry, I got your back. Below you will find the best of the best CDN providers classified in use-case categories.

FAQs

What is a CDN, and how it works?

CDN stands for “content delivery network“. The network consists of servers distributed across continents. Its primary role is to deliver online content to end-users. Once a user sends a request, the content delivery network caches it and serves the user with content from the nearest server.

The content doesn’t only include videos and images but also HTML, JS, and CSS code. The ultimate purpose of a CDN is to reduce DNS response and wait times and to increase web page loading speed.

Does my website need a CDN?

Not all websites need a CDN. There are several telltale signs that your website would need a CDN. Look at the geographical signature of your website traffic. If your website visitors come from all over the world, using a CDN will significantly reduce web pages load times.

If you notice sudden spikes in your website traffic, it’s another sign that you can benefit from a CDN. A CDN will serve cached pages taking a huge load from the origin server and preventing potential crashes. It is also a good option if your website is a target of bots and cybercriminals because it comes with several security layers to protect your content and the Origin server.

How to use a CDN?

To use a CDN, you first have to choose a provider and register on the official CDN website. Then you have to add the website you want to use CDN for. Once you are done with it, you will have to confirm and configure your DNS records.

The providers will provide you with new nameservers. Once you have them, go to DNS records in cPanel and update them using new nameservers. From that point on, CDN will cache your website and serve the content from the servers on the CDN. Bear in mind that this process will be different for each provider. Consult technical documentation and guides to properly use a CDN you invest in.

How much does a CDN cost?

CDN costs may warry. There are few free CDN services on the market, but they are often limited by either the number of requests or bandwidth or both. CDN providers usually have two pricing models. The first one is based on subscription plans.

The second pricing model is “pay as you go” meaning that you will pay for used bandwidth and number of requests. Some providers will also charge you for cache misses such as Google Cloud CDN.

Is it safe to use CDN?

Getting your content stored on servers across the world sounds like a risky endeavor. However, the top CDN providers keep your security tight. Their servers are locked behind several layers of industry-grade online security solutions, such as encryption. Your content will be safe.

On top of that, many providers have DDoS protection enabled to keep attackers at bay.

Conclusion

All 15 best CDN providers I listed are trustworthy and reliable companies with a longstanding reputation in the world of CDN. You’ve probably noticed that although they offer the same CDN service, they are still quite different. They use different technologies, offer unique dashboard UIs, and come with different features.
