What is a business/commercial website?

A commercial website is one created for a business, for which purpose is generating revenue or cash flow of any type (and that isn't under a non-profit organization). So if you're selling a product, selling advertisement, selling a service, or just marketing a commercial business, your site is commercial. A company website is also commercial even if it doesn't sell anything, as it's purpose is to front a commercial company.
