As long as the hosting business has existed, they started with the ability to have only one site hosted per account. As technology has improved as well as structures, there has been a shift in almost all hosts that allow you to purchase web hosting. They are now offering packages which include a set number of addon domains, and some allow unlimited add on domains. A wise choice is to still not host too many domains within the same account, however anyone looking to host a small network of sites can save big money doing it this way.

An add on domain is as the name implies added on to your existing hosting account. You will always host a primary domain name for your account, and your addon domain will be normally hosted within a subfolder on that account. So when you connect via ftp the first folder you see will be for maindomain.com files. You will then create a subfolder or the hosting will create the subfolder for you (typically related to the domain), like a folder named addondomain.com, will contain the files for your second domain. Now if you type maindomain.com, you will see it as its own site, and the same for addondomain.com. Your visitor will not know it is hosted on the same hosting as it will appear separately hosted.

Affordable low cost web hosting solutions are popping up everywhere, and normally the mid to higher based packages will offer add on domains as an option. Note, this does vary from provider. When you find the hosting provider offering the package you want, you then setup as many domains as they allow as addons using their procedures. Noting it can get messy with a lot of extra subfolders and you must remember to not delete them.

Now that you are able to host multiple domains within one account, enjoy your savings.
