For all practical purposes, Google is forcing the use of SSL and HTTPS on all websites! Prior to this, there was no need for you to purchase a SSL Certificate for your website and incur the expense of migrating your website from HTTP to the HTTPS protocol.
What is SSL
SSL (Secure Sockets Layer) is a standard security protocol for establishing encrypted links between a web server and a browser in an online transfer of data. A SSL Certificate is necessary to create SSL connection. Having a SSL Certificate installed on a web server ensures that all data transmitted between the web server and browser remains encrypted.
Google says, “Beginning in July 2018 with the release of Chrome 68, Chrome will mark all HTTP sites as not secure.”
What Needs To Be Done
You must enable SSL for your website which is done through your hosting provider. The SSL Certificates (annual renewal) and implementation choices and costs vary depending on the hosting company and the plan you have.
