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.
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.
