Having a secure website is important to any user searching the web. But, site security is especially important when personal information is being shared. Using HTTPS to secure your site is the optimal way to protect your users and you site from harmful hackers.
Hypertext Transfer Protocol Secure (HTTPS) is an internet communication protocol that protects the integrity and confidentiality of data between the user’s computer and the website. HTTPS is secured by Secured Sockets Layer (SSL) Certificate which provides three points of protection: encryption, data integrity and authentication.
Encryption makes sure any exchanged data is encrypted to keep it secure from eavesdroppers. Data integrity makes sure that data cannot be modified or corrupted during transfer without being detected. Authentication proves that users communicate with the website they intended.
There are three types of SSL Certificates; Extended Validation (EV SSL), Organization Validation (OV SSL), and Domain Validated (DV SSL). EV SSL checks the right of the applicant to use a specific domain while reviewing the organization. OV SSL check the right of the applicant to use a specific domain. DV SSL checks the right of the applicant to use a specific domain name.
As of 2014, Google has added HTTPS as a ranking factor. According to a study done by Backlinko, they found that HTTPS moderately correlated with higher rankings on Google’s first results page. Although the study didn’t find a strong correlation between HTTPS and higher rankings, it is good practice to have HTTPS in place for quality user experience.
