The motto for a successful wordpress blog is getting high and quality traffic. Now getting traffic is okay, but what about speed ? If your wordpress blog doesn’t load faster, how can you get maximum number of users? Speeding up your wordpress blog will need you to optimize it. With optimization you also need CDN (Content Delivery Network). CDN’s increase the speed and reliability of a wordpress blog while keeping the costs lower as possible. CDN’s also eliminates chances for a website to go down when there is high spike in traffic.
Content Delivery Network or CDN
CDN is a distributed network on internet, deployed in multiple data centers around the globe. CDN delivers the cached contents from a website to the users requesting it. CDN’s work based on geographical locations, requests are fed from the nearest data center according to geographical location. In a CDN, the cached contents of a website is stored in every server situated in various geographical locations. The updates to these servers takes place at the same time. It means all CDN based servers always have the same content to deliver to the user.
For understanding the working, let us take an example. Suppose a user in India opens “technoxpad.com” website via his browser. The hosting server of technoxpad.com is in US. With CDN services active the request will be fed from the nearest country from India where the CDN server is placed. There will be no direct request moving to the US based server. This will release the load on the main server and will certainly improve speed.

Need for CDN
Using CDN can greatly improve your wordpress blogs speed. CDN insures you speed, lower bounce rate and seo.
- Speed: If CDN services are used in a blog then the requests will be handled by nearest server as per geographical location. Thus user will be served as quick as possible.
- Lower Bounce Rate: As the blog’s loading speed is improved the users will be fed with their request quickly, thus there are very less chances that users will close your blog. As users spends more time in your blog will improve the bounce rate and also the pageviews.
- SEO: SEO (search engine optimization) is a very important factor for every webmaster. It is clear to every webmaster that faster blogs rank well in Google search. Thus improving speed means you have optimized it for search engines..
- Less Possibility of crash: It is very hard for a webmaster to see the site going down again and again due to high spells of traffic coming in. Using CDN, traffic gets distributed into multiple servers, therefore the main hosting server will receive less request. This will give less possibility of crash.
There are many CDN service providers around the internet with different price plans based on services. Choosing a particular CDN service totally depends on your budget. Here are few from the list of CDN providers.
