In the last 24-36 hours, millions of webmasters received a message from Google Search Console (formerly Google Webmaster Tools), warning them that their websites will begin showing “security warnings” if they don’t make changes to their site by October 2017.
Recently, Google announced that they would begin giving a rankings boost for sites that were secured (https/SSL). That’s great, and it makes a lot of sense, but the majority of sites are currently non-secure.
