Unlike some years back when sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic site. Few people can build this type of web site completely from scratch though, so the most convenient solution to have a dynamic website is to use a script application. Lots of website hosting companies offer script installers you can use to add such an app for each of your domain name or subdomains, so you will not have to add anything manually. The benefit of using an installer tool would be that the scripts are ready to use in just a few minutes and the copy that'll be installed is already with the settings necessary for it to run adequately on the particular hosting server, so you will not need to alter any script or account settings. In this way you can effortlessly create one with simply a few clicks even though you may have never had an Internet site before.
