I have decided to setup my own ecommerce website. I am a small business with less than 10 products and I chose Prestashop as the platform since it comes with host that I use so I don't have to install it manually. During install process it ask me to choose my http and https protocol, I have absolute no idea what is a SSL certificates. After doing a few research I totally understood what it does. Unfortunately, my domain didn't come with it so if I want I need to purchase as addon.
My question is: Is SSL necessary necessary for a ecommerce website? Did anyone here apply this certification to their shopping sites? I plan to advertise my website via Google adwords with individual account so does google allow non-SSL site to run the shopping ad on adwords?
