Content Delivery Network.
A CDN or content delivery network is a great way to gain access to more people all over the world by having your website caches in a cloud-like network. This means that the main server you work on and hosts your site is located near you, your content will be served to web users by a local server decreasing load times and increasing responsiveness. Google as others also considers load times and optimization a factor when ranking your site so even though you have basic hosting a CDN will help with those factors by speeding up that process since they always use high-end servers and internet connections.
SSL and HTTPS.
Another important change is the enforcement of the https protocol for all websites, not just websites that have online transactions. So your entire website has to be using the https://your content, to increase its ranking. This will prevent the spreading of malware and make the web a safer place. This also ties into the end-user experience. You can either get an SSL certificate to start using the https:// protocol from your hosting provider or from your CDN network.
