In 2014 Google made an announcement stating they would boost sites using HTTPS encryption in search results. Apart from that there are several other great reasons for using HTTPS. This site is hosted on Squarespace and while you could access this via a squarespace.com subdomain, I prefer using my actual domain that I own and control.
After some searching I came across this excellent blog post describing how to get SSL for your Squarespace site using CloudFlare. Its fairly straightforward to set up and doesn't cost a thing.
