Not Only eCommerce sites need an SSL certificate! Encryption is generally required for all sites, whether e-commerce or blog sites. Google Chrome users are warned when they visit a site that is not SSL certified that the page is not secure. Most users already have information about checking secure connections, so installing an SSL certificate is something you will seriously need. In fact, by installing an SSL certificate, you show your audience that you are a professional organization. So the use of SSL is not limited to e-commerce sites.
