Unlike some years back when websites were almost exclusively static, the standard these days is to have a feature-rich, dynamic web site. Not many people can create this sort of website completely from scratch though, so the simplest solution to have a dynamic website is to use a script application. A lot of hosting service providers offer script installers which can be used to add this kind of an application for each of your domain or subdomains, so you will not have to set up anything manually. The advantage of using an installer tool is the fact that the scripts are ready to use in a couple of minutes and the copy which will be installed is already with the settings needed for it to run the way it should on the specific hosting web server, so you'll not need to alter any script or account settings. In this way you can easily create one with just a couple of mouse clicks even when you have never had an Internet site before.
