Once you’ve determined whether your domain is available, you will want to purchase it from a domain registrar or web hosting company. Some web hosts will register a domain name for you for free (usually for one year) when you buy a web hosting services from them, while others will do it for you, but you’ll have to cover the registrar fees (an annual fee of $10 – $15 for the “.com” domain).
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.
It shouldn't come as any surprise that, like other web host providers, A2 Hosting's unlimited plans aren't actually unlimited. It expect you to use its service like "similarly situated customers." This is like being on a highway. If everyone is going a few miles above the speed limit, you're probably okay, but if you're barreling down the fast lane past everyone else, you're probably going to be asked to slow down.
With WordPress being such a versatile website platform, it’s no surprise that it can let you build a fully functional eCommerce online store. By fully functional, we mean that you can list any number of products, make them available for sale, and then also collect orders from customers and even handle all tax- and shipping-related elements of the whole process.
You can get started for roughly $10 per month for shared or WordPress hosting if your website doesn't require much server horsepower. As your business expands, however, your website may need greater horsepower. That's when you should look into cloud, VPS and dedicated hosting. These levels of services are for when you really need a web host that offers lots of storage, a significant amount of month data transfers, and numerous email accounts.
