It’s rare when Google reveals any of its actual ranking factors, so it came as a big surprise when representatives announced they would reward sites using HTTPS encryption with a boost in search results.

Webmasters balance this out with benefits that include increased security, better referral data, and a possible boost in rankings.
"Much of the web is now moving towards SSL encryption, and within a few years it may even become the default. SEOs, consultants and agencies that become experts know may be rewarded as the popularity of the protocol grows."
Will you make the switch to HTTPS?
