We really like to research and share ways to make your WordPress site faster. One of the no-brainers when it comes to speed nowadays is to utilize a content delivery network (CDN). They talk the load off of your wed server while speeding up the delivery of content to your visitors thus making their experience better!
What is a WordPress CDN?
First off, you don’t want to get a CDN confused with your WordPress host. They are complete separate services. A CDN isn’t a replacement for your hosting provider, but rather an additional way to increase the speed of your site.
How a CDN Works?
For example, when you host your website at a physical data center location, such as US Central. When people over in Europe visit your website it is going to take longer for it to load verses someone visiting it from US. Because the data has to travel a further distance. This is what is know as latency.
( Latency refers to the time and or delay that is involved in the transission of data over a network. In other words, how long it takes for a packet of data to go from one point to another. Nowadays this is typically measured in milliseconds, however, it could be seconds depending upon the network. In other words, the further the distance the greater the latency, which equates to a longer delay.)
And that is when CDN comes into effect. It helps to reduce that latency by loading your site’s content from servers closer to them. These CDN servers are sometimes also referred to as POPS (points of presence).
