If you are interested in boosting your site’s SEO value, you unquestionably need to utilize HTTPS. The primary purpose for this is because Google promises ranking boosts and additional SEO value for sites that protect their users with HTTPS.
The reason that Google requests users to use security encryption is part of an effort to make the internet safe and secure for its users no matter where they are. Google itself utilizes sophisticated HTTPS encryption across all of its platforms including both Chrome and Gmail. Websites that do not use security encryptions on their site compromise the level of protection and security that Google offers to its users.
