The time it takes for your website to load can significantly affect the user experience and how your online business performs. The time to the first byte and page load time are also important factors that influence your website’s SEO ranking.
That’s where some of the best CDN solutions can help. A content delivery network has other benefits, such as cutting down bandwidth costs, improving security, and making it globally accessible.

What Is a CDN Service?
A content delivery network - CDN - is a network of servers located at the so-called “network edge.” Closer proximity to the user means that the time the information needs to travel is greatly reduced, and a website or a web application loads much faster.
The content delivery network servers store a cached copy of your website, meaning that anyone who wants to access it doesn’t have to send the request to your main server and wait for the information to be delivered across a greater distance.
Apart from making your website faster, CDNs also improve its security and reduce the amount of traffic that goes through your main server, thus reducing bandwidth consumption.
How Does a CDN Work?
When you’re opening a website, all it seemingly takes to get the page opened on your browser is to type in the address, wait for a second, and freely browse the page. However, it’s not as simple as that.
A web address like “www.example.org” is tied to an IP address, which is a string of numbers, such as 192.168.0.1 (this example IP is used for local area networks, and not websites).
In order not to have to remember a string of numbers ranging from 4 to 12 figures, the URL is sent to a DNS server, which serves as a figurative “address book.” The DNS server processes the URL request from your internet service provider and delivers the requested page.
The DNS forwards the request to the CDN service, which stores the cached version of the website, and redirects it to the node closest to the user based on their IP address. This is known as Unicast routing.
Most CDN providers use Anycast routing, which has advantages such as less traffic congestion, protection against DDoS attacks, and better availability, as multiple nodes with a single IP architecture have more redundancies than Unicast.
If you use a CDN for your website, visitors will be routed depending on multiple factors, such as the location request, CDN server load, and the type of content requested.
When the distance that data needs to travel is lower, you’ll have lower command input latency, better video streaming, and, most importantly, shorter website loading time.
An additional benefit of CDNs is having additional copies of your website in case of server crashes. While even the most affordable hosting providers have impressive guaranteed uptimes, you can still benefit from preparing for the worst-case scenario.
CDN servers are located at internet exchange points, and it’s one of the main reasons why they can speed websites up. These are locations where networks of multiple ISPs are connected to allow communication between them.
CDNs are also referred to as edge servers and are used to host a cached copy of static content, such as HTML, images, CSS, and JavaScript.
Top CDN providers are also used by large companies to distribute other types of media besides websites. They can host data for games, video, audio, and software, and deliver it efficiently to users around the globe.
How We Evaluate CDN Service Providers
Our main criteria for choosing CDN providers were network size, coverage, time to first byte, pricing, and support.
Network Size and Coverage
Waiting for a website to load can be frustrating, and it’s the main reason why a site can lose traffic, users, and potential customers. On top of that, Google can give your website a lower ranking because of poor load times. That’s why even a cheap CDN can make all the difference and help push your online business.
You can reduce your website’s bounce rate as CDN speeds up the time to first byte. Internet users are mostly used to instant access and expect to find information quickly, and this performance directly depends on the CDN’s network infrastructure (the number of servers) and coverage (how many IXPs have the provider’s servers). All these factors directly influence the speed of the CDN service.
That’s why we focused on CDN service providers with a robust network infrastructure.
Bandwidth
The amount of traffic your website attracts will directly impact how much bandwidth you need, and paying your hosting service for extra bandwidth may be more expensive than using a CDN.
When you’re deciding on a content delivery network provider, make sure to check what bandwidth they’re offering. You’ll need to compare it with your website’s traffic since going over your allotted limit may incur additional charges.
Some providers charge you for the actual traffic going through the CDN to your website, and this may be the best solution for smaller businesses.
Remember that traffic can vary, as some websites have more or fewer visitors depending on the season. However, it’s not always unpredictable, and you can plan for an increase in traffic following certain promotions, such as after a successful email marketing campaign.
Since a CDN directly lowers the bandwidth requirements for the origin server, you might also consider downgrading your subscription plan if you’re currently paying extra for more bandwidth.
Pricing
The pricing will dictate how much you can invest in the infrastructure of your online business. You have the option of paying based on the amount of data transferred, the number of requests processed, or you can pay a flat fee.
There’s always the option to try CloudFlare for free and see for yourself if you actually need a CDN. Certain providers also offer discounts for long-term subscription plans.
You can always compare pricing plans and decide on those that meet your needs and then upgrade further down the line if necessary. Companies that we listed here have scalable solutions you can adjust to your requirements.
Customer Support
You can have the best content delivery network in charge of caching your website, but something can still go wrong and have a disruptive effect on the day-to-day operation of your online business.
If you’re not someone with previous experience using CDNs, you’ll definitely need help at some point.
The providers we listed here are known for good customer service, and most have support teams that are available 24/7. Available communication channels are usually email and live chat.
Security
Top CDN solutions implement much-needed security measures, such as DDoS protection. Some services even include free SSL certificates. Even if you’re not considering using a CDN for a website that hosts user data, such as payment information, you can benefit from the basic security it provides.
However, if you’re considering starting an eCommerce business, it’s better to find a CDN that has a good set of security features. Some are compliant with PCI DSS, meaning that visitors can confidently use the site without worrying about compromising their payment card data.
If you don’t already have a hosting service that provides you with an SSL certificate, you should seriously consider finding a CDN that will. Having an HTTPS instead of an HTTP address lets your users know that the connection is encrypted and that nobody can spy on them during the session.
This encryption is also necessary for ranking well on Google, as it’s one of the multiple factors that determine how easy it is to be found via Google search.
Top CDN providers include DDoS protection in their plans. This cyber threat is just one of the many tactics commonly used by malicious parties to disrupt websites.
If you’re using a content management system such as WordPress or Drupal, you should consider a service with a web application firewall. Such security measures are effective against SQL injections and cross-site scripting.
How To Find the Perfect CDN for You
So, how can you be sure if a certain CDN is the best option for you? You’ll need to consider where your audience is from, what type of content your website has, and if your website is static or dynamic.
If you’re aiming to reach a global audience, using a CDN is a much better option than relying on a single server. You can expect much better performance and faster load times anywhere.
A CDN provides great value for static websites, as it can cache the content without the need to fetch it often from your server. For websites hosting video files or streaming content, it can help with reducing latency and improving user experience.
