Unlike some years back when Internet sites were almost exclusively static, the standard today is to have a feature-rich, dynamic site. Not everybody can build such a web site completely from scratch though, therefore the handiest solution to have a dynamic site is to use a script app. A lot of website hosting service providers offer script installers which can be used to add this sort of an application for each of your domain name or subdomains, so you will not need to add anything manually. The key advantage of using an installer tool is that the scripts are ready to use in just a couple of minutes and the copy which will be set up is already with the settings necessary for it to run the way it should on the particular hosting server, so you will not have to alter any script or account settings. That way you can quickly create one with just a few mouse clicks even though you may have never had a site before.
