If you are a website owner, you would undoubtedly want to improve your search engine rankings. There are many ways like choosing an efficient hosting service, installing caching plugins, adding backlinks etc.
One of the quickest and most effective ways to speed up your website, is to use a Content Delivery Network also known as a CDN. The website which loads fast, has a higher opportunity to rank better and do good in terms of search results.
A well-integrated CDN works like a charm in increasing your website’s speed, overall user experience and ultimately your website’s ranking.

What is a CDN?
A CDN refers to a group of servers (Points of Presence-PoP) that are geographically located around the globe, who work together to provide fast content delivery on a website, delivered by the server closest to you.
Websites are targeting a global audience these days, and that’s why they are becoming more and more interactive, and this can slow the downloading speed. A well-integrated CDN assists in the transfer of assets like images, videos, and HTML pages across the globe much faster than the static server would.

How does CDN aid in speeding up your website?
So, regardless of how large media files you have on your website, a CDN allows your visitors to interact with your website just as fast as the locally based ones.
Simply put, a CDN helps in closing the distance between your website and a visitor.
Why do you need CDN?
Did you know that even one-second delay in loading time of the website page can result in a 7% loss in customer conversions? So, if you are concerned with your website’s global connectivity, you must consider using CDN. Moreover, Google announced that they will be focusing on Core web vitals in 2021, and one of the bigger points is using a CDN.
Let’s have a closer look at why CDN is essential for your website’s success in the search results.
If you have a global website, the one crucial step if you want to run a website successfully, is having a CDN. A CDN makes the content on your website globally available without any interruption or delay using servers (PoPs) that are widely located around the globe.
Dispersed Points of Presence (PoPs)
Suppose a visitor of your website is in a different time zone. When the visitor makes a query, the content delivery can be slow, and this can affect the overall user experience. This is where CDNs come in handy. With servers located near the geographic location of the visitor, content delivery will be swift and easy.
Using the globally scattered servers, CDNs replicate the website’s content. The visitors are often closer to the PoPs than the main content delivery site (main server). The closer the visitor is to the PoPs the less the delay will be in delivering the content.
Low network congestion
Network congestion means the reduced network quality when a network or link carries more data than it can handle. It occurs mostly when a large number of visitors want website access at the same time. CDN redirects visitors to the replicated content, which then aids in reducing network congestion.
DDoS attack prevention
A DDoS or Distributed Denial-of-Service attack is an attempt to disrupt the regular traffic of a specific service or network by flooding it or the surrounding infrastructure. Assume an unexpected traffic jam, clogging the road up for the regular traffic.
This attack not only affects the availability of the website but also the reputation of the website comes into question. A CDN helps to clear this network by transferring the traffic to other servers and prevent your site from being completely unavailable for genuine visitors.
Improve search engine rankings
As discussed above, CDN helps in removing the unnecessary jamming of the visitors so this will ultimately affect your website speed and your website will load within seconds.
It’s because page loading speed is one of the main factors determining a visitor’s experience, and for Google, nothing is more important than a satisfied visitor.
Therefore, if you want to increase your website’s ranking your website should load with a blazing speed and a well-integrated CDN can be your life-saver in this regard.
Reduces bandwidth cost
To reduce the cost of hosting, CDN uses caching and other optimisations to reduce the data amount an origin server normally provides. This aids in the reduction of bandwidth consumption cost for website hosting.
How to choose a perfect CDN for your website?
There are tons of CDN options in the market, claiming to provide the best service. Choosing the one which is just perfect for you can be an arduous task because all may seem similar initially. However, with further analysis of the features, you can visibly see the striking differences between them.
Analyse your requirements
Before analysing and comparing CDNs available, you must figure out your own needs and requirements. Take a few things into account like your budget, geographic location of your visitors, and type of media (images, videos etc.) you upload on your website.
Initially decide what you want from a CDN network and then choose accordingly.
Your visitor’s geographic location
Take into account the geographical location of your target audience. Considering whether they are local, regional or global, choose your CDN plan accordingly. It is essential to select a CDN whose PoPs are in the geographical location of your target audience.
Before choosing a CDN service for your websites, your initial priority should be the speed and reliability. Three critical factors can help you measure speed and reliability:
Response time: How long a server takes to give a response to the browser’s request.
Latency: The amount of time a server requires processing a request for a media like image or CSS file.
Throughput: The steadiness of delivery of content.
The more the servers a CDN service has, the faster it will be delivering the content. Therefore, it is essential for a CDN provider to have a vast network.
Always prioritise your budget. Find a CDN which is easy on your pocket and delivers similar performance compared to the expensive ones.
When choosing a CDN, the security the CDN is providing should be one of your primary concerns. DDoS mitigation and encryption are some security features to consider.

If you run a website, you must have an idea of how important it is to keep the loading time of your content as fast as possible. Content Delivery Networks (CDN) increases your website’s loading speed by minimising the physical distance between the server and a visitor.
The three big names in the CDN world have to be Cloudflare, KeyCDN and StackPath. KeyCDN is a favourite of most of the website owners because of its super affordable prices and decent features. However, for security concerned website owners Cloudflare is their first choice. When it comes to innovative features like free Edge SSL certificate, StackPath takes the lead. If we compare the performance of these three in November, we can see StackPath is winning with KeyCDN a little behind it.
So the big question, should you use a CDN? Well, it depends. Is your target group only around you, are you a local webshop or a service company who only operates within your own country? Then no, a CDN would be a waste, however Google are focusing on Core Web Vitals in 2021, where they really do recommend you using a CDN.
If you are a worldwide business, whether it’s a webshop, SaaS or similar, you need a CDN, no doubt. Your visitors will be all around the world and your website needs to be fast for all your visitors.
I like Cloudflare because it is the most secure CDN on the market, and it offers you the free WordPress plugins. The setup is easy, and they also offer a free plan for anyone who would like to try them out. However, the features are limited with this free version. But, if you run a small business and are looking for more features at a lower price point, then KeyCDN should be your choice.
