There are several types of web hosting, but the vast majority of website owners use shared hosting simply because it's the cheapest. With this kind of hosting, your site is stored on the same server as a lot of other sites, leading to economies of scale and low prices. It's the obvious choice, then, for small, low-traffic websites. In our view, the best shared hosting provider today is Bluehost.
However, if you own or manage a large and complex website, or a group of websites, and you expect to experience big spikes in traffic, or high traffic overall, shared hosting probably won’t allow enough bandwidth for you to provide a reliable service to your users. As a result, users may find your site loads slowly, or not at all.
