I am planning of creating a free software in upcoming months. I also wants to monetize my advertise my software by different forms of advertisements. These are:
A) PPC advertisement on web site: This will be much like Google Adsense for websites
B) PPC advertisement on software downloader : This will be much like Cnet spotinstall and one will display one or two ads during the software download.
C) Advertising through software module: This will be much like OpenCandy.
