Best CDN services & Providers to Speed up your website in 2020

Last Updated on March 13, 2020

Content delivery network or content distribution network, shortened as CDN services / CDN providers, are actually a geographically distributed network of proxy servers which host static content (sometimes dynamic) and deliver a cached copy to the users, based on their geographical location.

The static files comprise of images, PDFs, videos, and static libraries such as JavaScript and CSS files. The main purpose of a CDN is to make the site load faster by delivering all the static files in minimum time.

The Need for a CDN

content-delivery-network-latency

Why there’s a need to load the site faster? Simply because no one wants to wait! With a tiny attention span on the web (less than three seconds), you would want to grab visitors and slow loading websites are just a big turn off. Many conversions don’t actually happen because the website is taking too much of a time to load.

Despite your powerful webhosting, heavy investing on resources, and optimizing website, it is not necessary that all visitors are experiencing lightening fast loading speed.

WordPress offers a multitude of solutions (like optimizing images, minifying CSS and JavaScript, and setting up a caching plug-in to generate pages faster and leverage browser caching for WordPress) for decreasing loading time of your website.

But the speed is still dependent on the physical location of the users and the server they are accessing your website through. And none of the ways come close to the use of a CDN, if you wish to increase your loading speed. Thus, investing in a CDN is particularly important.

Is CDN a substitute for host?

CDN works completely different from your regular WordPress host. No, they are not interchangeable and you would still need a host. CDN works as an ancillary service and not as a replacement. You use CDN to boost your site loading speed, and hosting is needed, well, to “store” your website and its content on the internet in the first place.

Your host remains the foundation of your domain where all your non-static files are kept. The CDN, on the other hand, takes all the static files (the bulk) and replicates it worldwide. For most of the websites, it is easy to implement CDN services on the top of the website hosting.

Types of CDN

There are basically three main types of content delivery networks –

Content service protocols – The most versatile, professionally managed, and powerful of CDN. It is fully managed hosted networks which gives access to website files to the users.

Peer-to-peer CDN – It is a basic CDN which runs on a basic setup and small costs. Peer-to-peer (P2P) setups work between personal computers. It is not recommended for big and heavy websites.

Private CDN – If you don’t like either of them, you can create your own private service. It involves creating and managing your own global network of servers to serve static files.

How CDN Works?

Let us now understand how a CDN works. But before that, let’s understand the concept of latency in layman terms. Imagine there is a shoe factory in Oregon. You live in Pennsylvania and want to order shoes from that company.

Of course, the time taken to ship and deliver the shoes from Oregon to Pennsylvania would be too much. Now, imagine the same shoe company opens a factory outlet in New York which has the same shoes that you want to buy.

Naturally, the time taken now to ship and deliver would be significantly reduced. The same concept is applicable for data. If your website is hosted in North America and you have chosen a physical server that too is in North America, the users from Europe will have to wait longer for the website to load than the users from America will.

This waiting for the data to load over a network is called “latency”. Our aim to use a CDN is to reduce the latency and provide the same experience to all the users, regardless of their physical proximity to the physical location of the server.

cdn-services-working

We will understand the working of a CDN in three simple steps. For the newbies, implementing CDN can be overwhelming at first but these steps will help in getting the knack.

Step 1 – Choose a CDN provider from the list given below and subscribe to its services. Most CDNs charge on a monthly/annual basis or by data use. You can use the calculator function to determine cost that will be incurred by you.

Step 2 – Choosing a plugin such as WP Rocket or CDN Enabler to integrate CDN to your host. All your website assts will be automatically linked to your CDN by your plugin.

Step 3 – Now when a user is visiting your website, he will be shown the content which is being loaded from a POP close to his physical location.

How a CDN knows about the user’s location?

Well, CDN typically use two different types of technologies to fetch content for users according to their correct location. A CDN uses IP Anycast along with geo-location routing. Thus, it can detect the location of the user and then routes the request to the nearest POP. That being said, it is still important that you choose a strategic server location for your WordPress host.

Even though CDN will boost your website speed significantly by distributing media and content, a single request still has to be made to the hosting provider when your website is loaded. Unless you are using full page caching on a proxy server, your host will be still approached first for loading content.

Benefits of CDN

cdn-services-providers-benefits

Let us now take a look at all the benefits you will reap on using a CDN –

Speed – Speed is the main reason why webmasters choose to use CDN. You will see a significant improvement in site loading, reducing the lags and latency. CDN reduces the physical distance between the user and the server, thereby reducing the load time by a great margin.

Security – Many CDNs go beyond just speed and offer extra layers of security. Additionally, your data and customer transactions will be protected and attacks such as DDos, DNS Amplification, and Layer 7 will be averted. This reduces manual intervention and guarantees safer experience.

SEO Advantages – Speed is a crucial ranking factor. Having a CDN serve your content makes everything fast, not just to the users but search engines too. Your images will be crawled at a faster rate and you will also notice better SERPs. This overall positions your website in a better place.

Wider global presence and reach – CDN distributes your content to a multiple servers. This means that even if the main website server fails at one point due to any reason, your website will still be up to handle the incoming traffic. The rest of the servers will entertain the traffic wisely.

Higher conversion – Users tend to abandon a website which loads slow. By having your website load faster, you will see better retention rate and thus, better rate of conversions. So if a user spends even a few seconds more on your website, he is more likely to see your call to action.

Lower bandwidth expenses – A CDN can cut your bandwidth requests by up to 70% because it removes the excess load of resources from the main server. This compensates with the extra cost you will bear with choosing a CDN, plus you get more benefits!

You need CDN, If

By now you have learnt what a CDN is, how it works, and the advantages of using it. Now, the question arises – how to determine if your website requires the services of a CDN? There is no concrete answer to this. If you are a small website owner and don’t have splurge or traffic or simply catering to a fixed geographic location, there may not be an immediate need.

But if you happen to own a large website which has a considerable amount of daily visitors or which serves global audience, you should consider investing in CDN services. Now, it is totally your call. However, we recommend going forth with CDN because there are other benefits which will surely help you gain momentum sooner or later.

Some of the situations where it becomes imperative and imminent to opt for CDN are –

  • You are noticing a surge of visitors on your website and your current hosting plan isn’t sufficient to handle it.
  • Your visitors are from across the globe and not just restricted to your state or country.
  • The content, particularly media files, on your website is heavy and takes a lot of time otherwise to load fully.
  • Your website attracts sudden spike of traffic or is busy on particular days of the week or year.
  • If you have a resource website that fetches resources from a third party website, software, or service.
  • You run a forum or community where users communicate with each other and often share rich content.

If your website falls into any of the aforementioned points, it is high time that you switch to CDN. If you don’t want to invest in CDN right now and still want to boost your site loading speed, there are a number of techniques that you can apply.

Of course, the workability of these techniques (image optimization, CSS minification, and caching plug-in) depends on the type and size of the content your website serves. Sometimes, they may be enough and sometimes, you have no other option other than going for a CDN.

What to check before choosing a CDN

CDN comes in two types – free and paid. If you have decided to go for CDN, you will be faced with a number of factors that you should consider before selecting a CDN service. These factors are –

  • Pricing – It should fall in your budget. Choosing a free or paid service solely depends on this.
  • Server availability – The location of the server with respect to your traffic source.
  • Real time content purging – Content should be delivered in real time.
  • Free SSL integration – For extra layers of security.
  • Customer support – In case of troubleshooting and errors.
  • HTTP/2 support – For support to HTTP/2 websites.
  • User-friendliness – For ease of access, analytics, and smoothness of navigation.
  • Integration – You should be able to integrate your website easily, either through a plugin or a caching tool.
