There was a time when nobody cared about SSL. Nowadays it is vital that your website is SSL-enabled. Latest versions of browsers mark websites without SSL as insecure. Moreover, Google search gives a little bit higher priority to websites with SSL.
Honestly, it’s sort of lame if you run a website and do not provide SSL. Gone are those days where SSL was expensive. You can get an entry-level SSL certificate for as low as $8 to $12 (depending on the vendor and seller) per year.
