The SSL (Secure Sockets Layer) certificate creates a secure connection between two systems and encrypts data such as passwords, credit card numbers, etc. so that they cannot be read by a third unauthorized party.
With an SSL certificate, you protect the personal data of your clients and secure online transactions with them. This way you create, a trusted environment where your online customers can feel secure.
The SSL certificate is now a Google requirement because it protects both you and your website’s visitors. It also boosts website traffic as Google has announced that websites without an active and up-to-date SSL certificate will not rank high in its search results.
