Do you have any idea how much companies pay for ads in popular websites? Say, how much do they pay for 1M visitors?
I4C brings up some great points. 1M visitors in a porn site won't bring in All-State Insurance Other questions that a serious advertiser would ask I think would be source of the traffic, page views, time on site, etc.
big companies advertising their banners on high traffic websites like Yahoo i heard pay per day i think i read somewhere, but i may be off by a lot...that to advertise a banner on yahoo homepage, it costs around $370,000 for 24 hours...
