Unlike some years ago when Internet sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic Internet site. Not many people can build this sort of web site from scratch though, so the simplest solution to have a dynamic website is to use a script app. A lot of website hosting providers offer script installers you can use to add this type of an app for each of your domain or subdomains, so you will not have to install anything manually. The main advantage of using an installer tool is that the scripts are available to use in a few minutes and the copy which will be set up is already with the settings required for it to run properly on the specific hosting web server, so you'll not have to adjust any script or account settings. In this way you can quickly build one with just a couple of mouse clicks even if you have never had an Internet site before.
