When you add one to your website your visitors will know the information sent from them to your site will be secure. For example they may not want to send their credit card information without knowing it will be secure.
With the SSL certificate the websites identity is identified, then the customer can send information securely from their browser to your website. Essentially there is a secure connection created by the digital certificate, there is nothing additional that the consumer must do.

- the certificate holder’s name
- a serial number
