If you did not know it already, HTTPS makes your webpage more secure. This is because the data exchange between the server and the user is encrypted when your website is secured with the HTTPS protocol. You can verify this by looking at the URL in loading bar of the browser and seeing if there is a lock icon there. It has become an important feature for Google SEO rankings since 2014. If you don’t see the lock icon, you will need to get an SSL certificate which can be obtained from many web hosts. You will need to install it on all pages but you need to do it only once.
