SSL is a protocol (set of rules) that is used to establish a safe connection between two parties over the internet. It works by using a combination of cryptography and authentication for protection of the transmitting data from one node to another. During the process of SSL handshake, the participants exchange a series of messages to negotiate the details of the encryption. Once the handshake is complete, the secure connection is established and it’s possible to start exchanging encrypted data.

This technology is commonly used to secure sensitive information, for example card numbers or personal data. It is also used to authenticate the identity of the parties involved in the communication and to avoid data interception by an unauthorized third party.

When you visit a website protected with SSL, your connection to the website is secured and any information that you send or receive from the website is encrypted, making it much harder for anyone to intercept or access your data. You can usually tell if a website is using SSL by looking for the padlock icon in the address bar of your web browser or by checking for the “https” prefix in the URL.

Google does not require websites to have SSL certificates in order to be included in search results. However, having it can be beneficial for your website’s rankings in Google because it is seen as a sign of trustworthiness. Also SSL is important for protecting sensitive information that is transmitted over the internet, such as login credentials and financial information.

For this reason, it is generally recommended for everyone related to online payments, such as online stores or financial services. While SSL is not strictly required by Google, it is a good practice to use SSL to improve the user experience.

It’s worth noting that some CAs offer discounts for longer validity periods, so purchasing an SSL certificate for a longer period of time can potentially save you money in the long run. It’s also important to consider that with SSL, you increase user security and trust, and this may outweigh the initial cost.
