Unlike some years ago when web sites were almost exclusively static, the standard today is to have a feature-rich, dynamic site. Few people can create this type of site completely from scratch though, therefore the simplest solution to have a dynamic website is to use a script application. Lots of website hosting service providers offer script installers that can be used to add such an app for any of your domain name or subdomains, so you will not have to add anything manually. The main benefit of using an installer tool is the fact that the scripts are ready to use in a few minutes and the copy that'll be installed is already with the settings required for it to run adequately on the specific hosting web server, so you'll not have to adjust any script or account settings. This way you can easily build one with just a few mouse clicks even if you have never had a website before.
