Shared hosting is web hosting in which the provider houses multiple sites on a single server. For example, Site A shares the same server with Site B, Site C, Site D, and Site E. The upside is that the multiple sites share the server cost, so shared web hosting is generally very inexpensive. In fact, you can find an option for less than $10 per month.
Before we launch into our buying guide, you should know the three different categories on offer: shared web hosting (a good basic option if you're on a budget), VPS hosting (more flexible) and dedicated servers (for those running a bigger operation and in need of something more capable). If you're not sure which is the best level for you, you’ll find a detailed explanation of the different tiers at the bottom of this guide. It's also worth bearing in mind that you need to pick something that's going to be able to grow and scale up with you.
Many web hosting services offer so-called unlimited or unmetered service for whatever amount of bandwidth, disk storage and sites you use. It's important to understand that most terms of service actually do limit the definition of "unlimited" to what's considered reasonable use. The bottom line is simple: if you're building a pretty basic website, unlimited means you don't need to worry. But if you're trying to do something excessive (or illegal, immoral or fattening), the fine print in the terms of service will trigger, and you'll either be asked to spend more or go elsewhere.
