Unlike some years back when web sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic Internet site. Few people can create this kind of web site completely from scratch though, hence the most convenient solution to have a dynamic site is to use a script application. A lot of hosting companies offer script installers that can be used to add this type of an application for each of your domain or subdomains, so you will not have to add anything manually. The key advantage of using an installer tool is the fact that the scripts are available to use within a couple of minutes and the copy that'll be installed is already with the settings required for it to run the way it should on the specific hosting web server, so you'll not need to modify any script or account settings. That way you can effortlessly build one with only a few mouse clicks even if you have never had a website before.
