Google emails warnings to webmasters that Chrome will mark http pages with forms as ‘not secure’

If there are forms on a site, it will need to include an S. From Search Engine Land:

"Beginning in October 2017, Chrome will show the ‘Not secure’ warning in two additional situations: when users enter data on an HTTP page, and on all HTTP pages visited in Incognito mode."

Level Insight:

• The S at the end of https means that all communications between your browser and the website are encrypted. As cyber threats evolve, it is more important to encrypt all data — to take all possible precautions against sophisticated attacks and to earn customer trust by showing that you value the security of their data.
• Displaying the “Not Secure” message will hurt lead generation, as few prospects are willing to give their information to a site that displays such a dire warning.
• We are currently auditing all landing pages to ensure that we are taking the necessary steps to move any http pages to https as soon as possible. Note that this update does not only affect landing pages, but any page on your organic website that includes a form. It is essential to update prior to October to avoid any negative affects to your lead generation efforts. Please reach out to your account manager for assistance in http to https migration.
