On Thursday (2/6/20) Joe DeBlasio from the Chrome Security Team at Google published a blog post outlining the next steps in their campaign to have webmasters move to securing sites and files using HTTPS.
Google thinks your site is shady.
OK, not really, but that is how it will look come July, when all HTTP sites will be flagged as “not secure” in Chrome. In Google’s perspective, a site secured with SSL is a more trustworthy site. So with that in mind a regular HTTP site will be highlighted as “not secure“… for your protection.
