Unlike some years back when sites were almost exclusively static, the standard today is to have a feature-rich, dynamic web site. Few people can build such a site completely from scratch though, so the simplest solution to have a dynamic site is to use a script application. Many hosting service providers offer script installers you can use to add such an app for each of your domain name or subdomains, so you will not need to set up anything manually. The benefit of using an installer tool is the fact that the scripts are available to use in a few minutes and the copy that will be set up is already with the settings necessary for it to run efficiently on the particular hosting server, so you will not need to modify any script or account settings. This way you can effortlessly build one with only a couple of clicks even though you may have never had a site before.
