Unlimited Bandwidth is a web hosting plan feature that deals with the transfer or traffic your website has. It is useful to both personal and business websites assuming they have sufficient volumes of visitors and do not wish to purchase a dedicated server. Since each visitor to your website uses server resources, these resources aren't free. Unless, of course, if you have unlimited bandwidth web hosting. With unlimited bandwidth hosting you can have as much traffic to your website has you want - your hosting account has "unmetered bandwidth". This is a very difficult hosting plan feature to find because of the potential for server abuse by some websites is large and few unlimited traffic web hosts are willing to offer this shared hosting style regardless as to whether they price it cheaply or expensively. However, once you find unlimited bandwidth web hosting, you can sleep easy knowing that your website has found cheap unlimited bandwidth web hosting and thus bandwidth transfer is not a concern anymore. When you do buy unlimited bandwidth hosting, check the unlimited bandwidth description area of the hosting contract to make sure that you don't get "baited and switched." Unlimited bandwidth web hosting should remain a feature so long as you host your website with an unlimited bandwidth web host company - the no-limit bandwidth contract clause will confirm this.
