A prominent warning will be shown in Chromeâ€™s address bar (also known as the Omnibox), indicating that an insecure website is â€œNot secure.â€ This warning will show for all http websites.
Googleâ€™s announcement was firm about their goal to warn users of insecure sites, with the intent ofÂ further shepherding more web publishers intoÂ upgrading to HTTPS.

Worldwide Impact of Chrome HTTPS Security Warning
The impact will be felt more keenly in some countries than in others. But even in countries where the use of Chrome is low, this still represents 39 percent of Internet browsers.

Nevertheless, the clear answer is that all web publishers should at least consider upgrading to HTTPS. This is no longer a consideration limited to e-commerce sites.
The warnings may cause site visitors to begin negatively reacting to warnings on sites that have not upgraded, which may affect advertising impressions, lead generation, sales and so on.
July 2018 is the deadline for when prominent warnings will begin to show to Chrome users. The clock is ticking.
