First time you must answer the question which type of web hosting are you looking for. If you want to run a single web site shared hosting will be the right for your needs. For those who own multiple domains it will be better to buy reseller account or look around the web hosting industry and find some hosting plan which allows more domains under single account. Most web hosting companies allows only one domain hosted but because web hosting is very competitive market so if you will search carefully you will probably find some providers which offer more. If you want to drive an advanced business and need more system resources then acceptable on shared server you will need your own, dedicated or virtual private server.

As soon as you decide which type of web hosting is the best solution for your project you should make oneself clear about features you will to use. Consists your web site from static *.html files only or contains PHP or CGI scripts? Webmasters using PHP probably will need MySQL database. Most of web hosting providers offer these features in their basic hosting plans but some extremely cheap hosts (with prices about $1 or $2/month) limit you to use static pages only. If you decide to use some of these very cheap hosting plans make sure of the possibility and price to upgrade to higher plan with more features. Don't forget you don't need to be programmer to run dynamic web site. There is plenty of free PHP or CGI scripts on Internet.
