Improving loading speed is an invaluable upgrade for your website. It will not only withstand heavy loads from numerous simultaneous user requests but will also attract new clients. That’s right — Google algorithm assesses load speed as a part of user experience via Core Web Vitals signals. If it is good, your page is more likely to get higher in search and receive more clicks! And according to Kissmetrics research
. Now that we’ve got your attention let’s see how to improve the load speed using CDNs (Content Delivery Networks).
40% abandon a website that takes more than 3 seconds to load
We’ve already explained what the origin servers are. In short, they store the original version of your website. They do have a physical location though, and the time (or delay) it takes for the data to travel from this location to your device is called latency. And the closer to 0 it is, the better. However, it can never reach 0.
The reason is simple — data has to travel through physical cables and wires. Nowadays, it can travel with the speed of light thanks to fiber optic technology. But thousands of miles on the bottom of the ocean take even light some time to go through. The time which might be precious. To decrease the latency, you should know the reason why it exists. There are three main types of delays:
As you can see, the solution to all these issues comes naturally — establish servers closer to the users. Such edge servers constitute the CDNs. And, thanks to geographical proximity and ramified linkage, the CDN latency is much lower.
While all CDNs generally increase the website loading speed, they might vary in effectiveness. That’s why it’s crucial to look into available CDN providers before choosing one.
CDNs are vital in case you want to improve your website’s load speed. They will also be a great helping hand if you target clients outside of a particular region. However, in case you don't, there’s still a reason to use CDNs: they might save you precious seconds needed for the client to stay on your page.
