What is a CDN? A layman’s introduction to content delivery networks.
In 2019 making sure your website is fast is essential. The speed that your website loads not only speaks to your businesses credibility, it also has a dramatic effect on your search engine ranking. Search engines like Google want their searches to have a seamless experience, so if they determine that your website takes too long to load, they are likely to direct their searches elsewhere.
The good news is there is plenty you can do to increase your websites loading speed and one of the simplest steps is to use a CDN. CDN stands for content delivery network and what it does is effectively copy your website to a series of different servers right across the globe. Then when a user accesses your website, it loads it from the nearest geographical server to ensure the site loads as quickly as possible.
For example, if I accessed your US based website from my home in Manchester, England, your website would load from a server in London not from a server across the Atlantic. This means it will load faster and more efficiently. It may only mean a difference of seconds, but the reality is that in 2019, seconds count.
A CDN works by Caching the static elements on your website and then loading them onto the various servers around the world. When a user accesses your site, the CDN first checks if their have been any changes made since the website was saved onto the remote servers. If there haven’t been any changes it simply loads the cached version. If there have been changes, it will update first, then load the website. This ensures that every user gets the latest version of your site, where ever it is they are accessing it from.
