Yes, yes and once again yes. We highly recommend that you get an SSL certificate for your website no matter its purpose, after all you can get a solid certificate for free using authorities like Comodo (cPanel) and Let’s Encrypt (all of our websites come free with the latter unless specified otherwise).
We strongly believe that in 2018 every serious website should invest the time and effort into getting an SSL, not only in order to add a layer of protection against potential attackers, but also help establish that initial trust with the person on the other side of the screen.
As outlined above, the intentions of Google are clear and we believe that the onslaught against non-SSL websites will continue. I personally speculate that sooner or later, Chrome will end up displaying a warning dialog every time you try to access a website without a certificate. Time will tell, but for the time being it is definitely in best interest of website owners to start looking into implementing an SSL certificate.
