If you have only started your blog, most probably, you have a tight budget but huge ambitions. It’s important to maintain good user experience, which is why loading speed should be constantly high. Most people are not patient, when it comes to website loading, and if it takes more than three seconds for a page to load, they are most likely to abandon it.

You might have already optimized everything on the blog starting from images and scripts and finishing by Gzip compression. But if you still don’t use best CDN for your website, it is not totally optimized. With a CDN (content delivery network), the speed of your WordPress blog can become much, much higher, so you will be able to serve content to end-users quickly and they won’t leave your site.

What is a CDN (Content Delivery Network)?

CDN is a network of numerous servers located in different countries, regions or continents. These edge servers cache static content of website including images, JavaScript, and CSS. When an end-user visits a website, he or she will have the content delivered to web-browser through the nearest server, which boosts loading time.

Why deploying a CDN?

As you can see, when that data is delivered from a distance, it will surely take more time to load. But, when the same thing is done through a server that is close to them, the site will be loaded very fast. Besides, CDN has many advantages for SEO and helps to prevent security issues.

Now when you know that CDN is a must for your WordPress blog, you need to find the one that will suit your project. If your startup needs money for development, you can save on CDN – there are many free services around. Read about seven worthy variants that can help your business.
