Since July 2018, Google Chrome is marking all HTTP sites as “not secure,” already post published today by Chrome security product manager Emily Schechter. Chrome now showing “not secure” to all website which is not SSL Certified. Every website based businesses are depend on two things, one is its own content and second is visibility and position on search engines specially google.
Google has been nudging users away from unencrypted sites for years, but this was 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.
The Chrome team said today’s announcement was mostly brought on by increased HTTPS adoption. Eighty-one of the top 100 sites on the web default to HTTPS, and a strong majority of Chrome traffic is already encrypted.

What is SSL?
SSL is an acronym for Secure Sockets Layer and it’s a cryptographic protocol for establishing an encrypted connection between a client and a server (i.e. your visitor and your website).
An important thing to understand is that “SSL” is the legacy term from the times when it was the only protocol of that kind on the web.
Nowadays, SSL as a protocol isn’t used much anymore (or at least it shouldn’t be) due to its age/weaknesses, which is why its successor TLS (Transport Layer Security) has taken over. Most of the time, when someone says “SSL”, they actually mean “TLS” without knowing it.
