Fill in the blank. According to the latest statistics, 60% or more of all results for high volume keyword queries in the TOP-3 have already been moved over to run on ______

The correct answer is HTTPS. Google has been actively promoting and prioritizing secure websites (those using HTTPS) in its search rankings. This initiative, known as "HTTPS Everywhere," aims to make the web safer for users by encrypting data transmitted between a user's browser and the website. As a result, a significant majority of high-ranking pages for competitive keywords now use HTTPS. FTP (File Transfer Protocol) is used for transferring files between computers and is not a protocol for serving web pages or influencing search rankings. HTTP (Hypertext Transfer Protocol) is the unencrypted predecessor to HTTPS and is less secure, hence Google's push to move away from it.
