You want your SEO ranking to go higher! Then it’s here; a new Google ranking factor. In the year 2014 Google announced that HTTPS websites are ranked higher in the Google searches then the usual HTTP websites. HTTP is a risky website which risks data breach from third parties. HTTPS is similar to HTTP, but with an extra layer of security; equipped with the SSL - Secure Sockets Layer, to monitor and transfer data safely between the web server and the browser. SSL encrypts data being transferred between two parties, provides authentication for users, and ensures that data are not corrupted or altered during transmission process. Hence your sensitive information such as credit card information, usernames, passwords etc is secured when you are using it.
HTTPS is not only good for security but also for referrer data, page loading speed and other SEO strategies. Futuristically to cope up with Google’s algorithms it is always recommended to have HTTPS.
