A CDN or a Content Delivery Network is a method by which you can send content from your website to people living in a geologically specific zone with much more speed and efficiency.
Sometimes, even with a good hosting plan, your site load speed can be compromised if your audiences are living far away from your site’s server.
When you use a CDN, you are basically caching and storing all your content on multiple servers. So the next time one of your audience wants to view some of your content, they will be redirected to the closest server, and will also notice a significant improvement in your site’s load time.
Besides this, using a CDN can lead to improvement in SEO and also reduces the chances of your website crashing.
