Google have announce the move to mark website not using HTTPS as Non-Secure in Chrome 62, which is due in October 2017.
This will be shown as a warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode. With a warning like that shown on all forms and login fields, your user might choose not to complete a form or login box, causing your conversions to drop, or even worse, your user go elsewhere.
Simple, migrate to HTTPS. To prevent the “Not Secure” notification from appearing when Chrome users visit your site, only collect user input data on pages served using HTTPS.
If we host and manage your site, we will move you automatically and inform you about any changes needed like new Google Analytics Properties etc.
We include SSL as standard on all our hosting, free of charge.
If you manage your own site, there are some good guides provided by Google on how to secure your site with HTTPS.
