Generally, you are shopping online from any website but have you ever noticed how credible that site is? After entering a website, you can look at the address bar of the browser to see if the site is using an SSL certificate. If the site address contains HTTPS, then it is associated with an SSL certificate. On the other hand, if there is only HTTP, then it must be understood that the website is not using an SSL certificate.
The primary reason for using an SSL certificate is to ensure that the data transmitted across the Internet is encrypted. So, not everyone can read the information except the server users are sending the information to. This can prevent hackers and cyber thieves from stealing user data. SSL ensures security between your website and the user. Besides Google prefers secure sites. Therefore, Google has officially announced that Google will give importance to the secured site in the ranking or will give more importance in the future.
