How to configure free CDN (Cloudflare) in WordPress with easy steps?

The CDN ( Content Delivery Network) is getting more popular nowadays. It is observed that our website is contained in rich content like images or videos, Google really wants too. The contents are loading inside a single server for worldwide access and will take more time to load the content. This means that If you are in ASIA, you are accessing a Europe based server which makes delays for data transfer from one end to another. 

The user experience of the website will decrease and no one will visit from another continent. Now coming into the current scenario. We can see that today the site data is distributed around the world. This is happening through CDN technology.

If you are not using CDN, then first note down the Page speed from GTmatrix, Pingdom, Google page speed checker. 

Then you will understand the changes after applying the CDN.

What is a CDN service?

Content Delivery Networks or CDN are the multiple server connectivity situated all across the globe to propagate all the website contents to be delivered easily without causing time delay. Some people may confuse the CDN are hosting providers and it isn’t. 

Looking into the below image we can see that the person querying the site which is hosted in the US, which means all the data has to be traveled from the US itself. The person from Europe is accessing the website and it isn’t loading smoothly due to the distance. The user is annoyed with the service provided by the website and never returns back due to time delay.

If a CDN is situated near to his location, then the CDN stores the data of the website and query completed by the CDN itself. The hosting provider’s load on the server reduces and ultimately the user is satisfied with the speed.

CDN working

Primarily the website loads on the webserver and the data changes will be copied to CDN networks. Then the networks of servers propagate the individual data and identify where the user location is and find the nearest CDN and route the query to that server. So these queries and returning data are happening in split seconds. Hence the speed of the websites improves.

Advantages of CDN service.

The major advantage is that the site speed can be boosted.

Every second count and it is valuable for business. If you delay 1 second then the customer will search for your competitor, who can deliver a fast response for the customer’s query to become their profit.

So website design and the service quality is second if the website loads in higher time what will be the purpose of the service quality. 

According to Kiss matrix, a 1-second delay in loading will lose 7% of the business. It is important to use CDN for faster response.

Another notable change you can see with the TTFB ( Time to First Byte). 

TTFB defines the initial phase of your content loading. A WordPress CDN can significantly reduce the TTFB. 

There are a number of reasons for higher TTFB such as misconfiguration, server-level caching problem, Code level errors, etc. The DNS resolving time is also added to the TTFB and there may be changes in the values at certain times.

The contents are compressed all along. It is mandatory to use the GZIP functions on the server because it reduces the contents traveling by reducing the size. We are not talking about images. The images itself compressed in different ways and automatically done while uploading. The  WordPress images optimized plugins are helping to reduce 70% of the size without changing the visual effect. Here CSS and JS are used by the Gzip functions.

Lower the server load.

The website data is distributed in different geographical locations. The data is loaded after implementing the CDN from CDN nodes. The primary webpage query will be supplied by the hosting server itself. Then the rest of the contents delivered by the CDN. So if any changes may come with the actual websites, the changes will re-distributes to CDN. The key point here is the hosting server load will be lesser compared to non CDN websites.

Band Width reduction.

If the website is loading from your datacenter. A number of unwanted bots and malicious scanners are looking for your websites. This time the bandwidth is utilized for the non-worthy users. What will happen, if we implement the CDN?

The CDN records all the traffic including Bots activity and other scanner software. It will effectively stop the CDN. The traffic referred by Google analytics will be actual, whereas the CDN gives you more traffic and users than the analytics. The above said is the reason. 

We already know the hotlinking of other websites in the security article. The hotlinking is another bandwidth-consuming nonprofessional activity and CDNs are disabled this function. We can also disable the hotlinking  within the hosting control panel itself.

High availability

If one of the CDN servers down, automatically redirect the user to another possible nearest CDN. This network never goes down, due to the load balancing technology. CDN can be upgraded with any number of servers according to the connected cached contents. If the larger content then the CDN network load increases. In this scenario, they can add another couple of networks without affecting existing connectivity. So the CDN also comes with high scalability.

What about the SEO advantages?

Yes,  Google officially announced that the ranking factor now determines with the site speed. The algorithm has changed after 2010 and they studied the user experience with site speed. which shows the user is spending less time on slow loading websites. So considering the ranking factor you have to move with the CDN in order to rank well on google.
