Support among the services varies widely, from free WordPress.com account's only offering community support, to Jimdo's email-only service, to Wix's telephone-callback service—even for free accounts! Many of the site builders offer rich online support knowledge bases and FAQs, so there's a good chance you won't even need to contact the company. I test each service's support as part of the review process by asking about some less-common site-building procedures.
In all Website Builder plans any data transmitted from your site will be encrypted using a SSL (Secure Sockets Layer) certificate. Your SSL will establish an encrypted link between your web server and the browser of the person visiting your site. This means that all data will be kept private; which is important if you want visitors to your site to be safe. If you want to sell products or services in your store, you will want to have a SSL since it protects credit card and bank numbers from being intercepted by hackers.
Before you can start building your home on the web, you need an address for it. Most of the site builders here can register a unique domain for you, and all can give you a web address using the provider's domain, for example, yourname.sitebuilder.com. Some include a custom domain name with their plans, usually requiring a year's commitment. The services also let you use a domain you've acquired from a third-party registrar such as pairNIC, but you often must pay the site builder for that privilege.
Just imagine Medium shuts down as did Posterous back in the days (which was a similar service). You will not necessarily lose all your content but all the SEO rankings you ever created. To get it right you need to publish on your own domain name and preferably on your root domain (www.yoursite.com/blog) and not a sub-domain (blog.yoursite.com). This has numerous SEO advantages.
