An SSL certificate reduces your risk by keeping sensitive data collected on your website safe. The data is encrypted and backed by a warranty from Comodo SSL that's worth up to $1.75M to protect the end user.
Having HTTPS in the address bar and displaying a seal of trust increases customer confidence in your website and helps drive more sales.
Good news. Google says that SSL security has a positive effect on its rankings:
"We're starting to use HTTPS as a ranking signal... for sites (that) use secure, encrypted connections (and) we've seen positive results."- Google Online Security Blog, August 06, 2014
