I am looking for an example of a revenue model ( or complete Bplan) of
a web site that their revenue model is based on online advertising.

It will be nice to get it on excel. It must have a detailed
?calculation? of the forecast.
(it?s not good enough to get just a number)

Assumptions:
1.The forecast is based on numbers from overture/wordtrack or google.
2.This site needs to pay in order to bring traffic (adwords or banners or more)
3.Example of a content web site is  www.fixya.com 


Please feel free to ask me any question.
