An info site may have affiliate links.
Even blogs have ads, and personal sites are often there to sell something - an individual - (hire me! listen to me!)
Ive seen com sites that are devoid of all selling, and edus and orgs that are full of it.
IId have a go in this very risky area and say a commercial site is any site that asks you to send money! Bad i know, but as good as i can think up right now.
