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.

Your website needs a place to live on the web, and the quickest way to reserve your web address is to find a web host. There are a variety of cheap web hosting providers, and each one has a specialty. Look for a web host that offers a price that fits your budget, has the web tools you need to create your envisioned website, and provides support when you need help or have problems.
