Business websites are usually different from websites that were established for many other reasons. You can see whether a website was established by a businessman or whether it was established by somebody who did it for fun only. A business website will always try to sell or advertise something, while a website made for fun will not attempt to do it. Business people will usually have to ask to build a business website for them or alternatively they can try to do it themselves. It all depends how advanced and experienced they are when it comes to building websites and how much patience they have.
