This is a cheap way to get started online but it has many disadvantages - you will encounter email delivery problems because of spam complaints against other sites on the same server. You will find your site's grinding to a halt when someone else does some heavy database work on your server. You might even find your site going down because of a denial of service attack against someone else hosting hacking or piracy related material on your server (these type of sites attract antisocial elements!)

How can you avoid all of this drama?

By upgrading to a virtual dedicated server. A virtual dedicated server lets you run your sites as if you had your own "dedicated" server, except it is cheaper because you are really just using part of a server that has been split into multiple virtual dedicated servers.

You can find out more about this by searching Google for "virtual dedicated hosting". Virtuozzo is the main commercial software that web hosts use to run virtual hosting services.

You will find virtual dedicated server accounts starting at just $30 a month. You'll get a much larger chunk of bandwidth compared to shared hosting, and none of the problems that go with a shared host. You can also get multiple IP addresses that are exclusive to your sites.

So what's the catch? Not much. You'll probably spend a bit more on hosting each month. The main disadvantage of upgrading to virtual dedicated hosting is that you will need to be more technically proficient so that you can administer the server.

This requires a bit of time learning the necessary Linux skills to make sure your server runs smoothly.

Many hosting providers will have a "premium" support offering that includes a bit more hand holding - this is definitely recommended if you don't have much experience with Linux, or are new to virtual dedicated hosting.

With the increased speed and bandwidth that a virtual dedicated host offers, and none of the shared hosting headaches, the move is one you will never regret.
