HTTP is an acronym for "Hypertext Transfer Protocol". You're probably familiar with seeing it used in front of the URL on your web browser. HTTP is fine to use when you're sharing public information, such as a blog post, home page or service menu. However, when a customer begins to type in sensitive information while making a purchase or signing up for a service, then that data is easily viewed by hackers and thieves. The "S" added on to HTTP stands for security. When you use HTTPS, then the information is encrypted using SSL, and the customer's information is no longer compromised.
SSL stands for "Secure Sockets Layer". When used, it helps not only to verify the identity of the website owner, but it encrypts data that is exchanged on the site. This is especially important when sensitive information is shared, such as social security and credit card numbers. By purchasing an SSL certificate, you are showing your customers that you care about their personal data enough to invest in protecting it. Trust rises between you and your clients, and people are much more likely to make a purchase or fill out a form if there's evidence of an SSL certificate. Many times, if an SSL is being used on a site, there will be a green lock icon in the search bar, and rather than the standard HTTP in front of the domain, you will see HTTPS.
Why Google Is Actively Encouraging the Use of SSL for Ranking
In 2014, Google announced that their algorithm would begin to reward websites who had an SSL certificate. When thinking about SEO, it's important to understand the reasons behind Google's choices. Keep in mind that it's Google's job to make their customers happy. They have become the number one search engine in the world because they have built a reliable reputation for helping people find the most relevant and dependable websites when they need it most. Websites that use SSL and HTTPS are more secure and are therefore much more likely to be a valuable and safe space online for Google to direct users.
