Starting in July 1, 2018, Google Chrome will mark all HTTP sites as “not secure”. Chrome currently displays a neutral information icon, but starting with version 68, the browser will warn users with an extra notification in the address bar. Chrome currently marks HTTPS-encrypted sites with a green lock icon and “Secure” sign.
Google has been nudging users away from unencrypted sites for years, but this is the most forceful nudge yet. Google search began down-ranking unencrypted sites in 2015, and the following year, the Chrome team instituted a similar warning for unencrypted password fields.
Eighty-one of the top 100 sites on the web default to HTTPS, and a strong majority of Chrome traffic is already encrypted. “Based on the awesome rate that sites have been migrating to HTTPS and the strong trajectory through this year,” Schechter said, “we think that in July the balance will be tipped enough so that we can mark all HTTP sites.”

HTTPS encryption protects the channel between your browser and the website you’re visiting, ensuring no one in the middle can tamper with the traffic or spy on what you’re doing. Without that encryption, someone with access to your router or ISP could intercept information sent to websites or inject malware into otherwise legitimate pages.
HTTPS has also become much easier to implement. Get an SSL before July so your customer don’t see this Google Chrome warning. Add an SSL to your Site
You could lose sales if you don’t get SSL soon. SSL is not only the right thing to do for your customers. it’s also great for boosting search rankings and getting more traffic to your site.
