How CDN can help your business: accelerate your website performance
Nobody likes sluggish websites. Slow loading page can cost companies a fortune because of lost sales. According to statistics, 47% of Internet users expect the web pages to load up to two seconds, so exceeding this threshold negatively affects your traffic – if the audience does not receive what it requires from the site, then ultimately the potential to lose all customers or readers is extremely great. At the same time, all these problems arise for the reason that the sites are located at a great distance from their visitors, but there is a solution – Content Delivery Network.
How does CDN (content delivery network) work?
To understand how CDN works, let’s imagine that you type a search query into Google’s search box. After you press enter, a server with the required page receives your request. The thing is that this server can be located anywhere in the world. And the loading speed will differ depending on how far it is located from your place. If geographically you are far from the server where the site is hosted, the loading time can be very long.
The point is that usually, websites contain over 90% of static content that is not unique for each user. Every time when users from different locations open your website, they download almost the same data from your servers, which are usually located in a single city.
This problem can be easily solved by CDN. Content delivery network servers are located all over the world and can cache and synchronize the same piece of content across all servers. When a user accesses the content of your site, the CDN simply redirects them to the geographically closest CDN server that has the corresponding file.
By caching data and distributing multiple requests for the same information across the network, rather than across a single server, the traffic load is more balanced. That eliminates problems such as latency, browser crashes, and maintaining.
Who needs Content Delivery Network the most?
First of all, projects targeted at users from all over the world. Secondly, sites using streaming video, for instance, various online cinemas. Thirdly, huge media portals that store a lot of information, for example, galleries or photo stocks. But besides the listed giant sites, CDN is also suitable for small businesses like online stores, news portals, forums, etc. Since fast website loading speed is an advantage for any business.

How your website can benefit from using CDN?
- Conversion rate improvement
Every second of waiting reduces the site conversion rate by 7% *
- Bounce rate reduction
Within three seconds, 40% of visitors leave the site
- Improved search engine ranking
The speed of the site affects the website ranking – search engines primarily show resources that do not keep users waiting.
- Cost reduction
Having shifted the load on the caching nodes, you will release the capacity of the main server for other projects and confidently cope with the growth of traffic.
- Increase in fault-tolerance
If something happens to one of the caching servers, users will receive content from the other closest one and will not notice any disruption to your project.
- Improve security
In case, all data transfer is processed through one server, it increases your vulnerability to DDoS attacks and other vulnerabilities. CDN can help you protect your sensitive data against hackers. Because CDN constantly updates TLS / SSL certificates, ensuring higher standards of authentication and encryption.
What should I consider while choosing CDN?
1. Network size
Your CDN provider should have points of presence in the required regions.
2. Geographical coverage
For example, some CDN providers have good coverage only in America and Europe, but poor in Asia and Latin America.
3. Cost and pricing model
- Many providers require contracting for at least 12 months (minimum contract term) and also charge a minimum fixed fee for the service every month (minimum monthly costs). Others work on the model of PAY-as-you-GO.
- A number of providers do not allow to quickly try their solution – you first need to talk with their sales team.
- Check whether you pay for Requests, Ingress and traffic volume?
4. Easy integration with your hosting
5. DDoS and Web Application Firewall (WAF) protection
If you want to maintain your level of service as you expand your presence on the Internet, a reliable, scalable content delivery network is a worthwhile investment. This will reduce the problem caused by delays and give your visitors the speed, performance, and consistency they expect from the website.
