What is CDN and Why is it Important

This post is very useful for those bloggers who are worried about the slow speed of their blog or want to speed up their blog. In this post we will see how to use Content Delivery Network (CDN) to load blog fater. So let’s know what is CDN and why it is necessary for blog or website.

What is CDN

If someone close to you throws a ball at you, and a person from far away throws a ball at you, whose ball will come first to you? From the nearest or distant person. It will be a foolish question because everyone knows that the ball of the near person will come to you first.

Well, when we host our blog on a server, the server can be in any country in the world. Now suppose that your website is hosted on a US server and if any user in US comes to your blog then the blog will load faster for US users than Indian users. Because India is far away from the US, so the blog will load slower for Indian users than US users.

It is quite simple that the page loading speed of your blog or website will be faster for users who are close to hosting server space. But we cannot host our website on servers of different countries for this. If you want your blog to load faster for any user from any corner of the world, whether users are near or far from your hosting server, then the Content Delivery Network (CDN) will help you.

Why Use CDN

All speed checking tools like gtmatrix, pingdom, Google PageSpeed ​​Insights etc. suggest CDN to improve the speed of website or blog.

If you want your blog at good position in the ranking of search engines, then it is important for your blog to be fast.

If the speed of your blog is good, then the users of your blog will visit more web pages of your blog, which will reduce the bounce rate of your website.

CDN makes the work of your server very easy and it does not take much time to respond to the server. Apart from this, CDN also reduces the bandwidth cost of your hosting.

If there is too much traffic on your blog, then your server may be down due to overloading, but if you use CDN, it also handles your high traffic and reduces the downtime of your server very much.

Apart from this, CDN also keeps your blog secure from Block spammers, scrapers, bad bots and DDoS Attacks.

Which CDN to Use for My Blog or Website

There are many CDN services available in the market including MaxCDN, KeyCDN, Cloudflare, etc. some hosting companies also come with built-in CDN.

Currently, I use Cloudflare CDN (available in Free and Premium version) on my blog. It also offers you a free SSL certificate for lifetime.

If you have not yet installed SSL certificate on your site due to low budget, you can install SSL certificate on your site for lifetime with Cloudflare’s free plan.

You can use any of the MaxCDN, KeyCDN, Cloudflare etc. on your blog or website.


CDNs play an important role in making a site run fast and smooth.

If visitors come to your site from all over the world, then you should use CDN on your site. This prevents your site from crashing, reduces server load, helps the site load faster, and much more.

If your budget is very low but you want to use CDN, then you can use Cloudflare’s free plan.
