I don't think this has been done before and I am very eager to try it out. The idea is that ad revenue sharing is calculated based on the PR of pages you link from. I provide the content, but ad revenue is shared by the people who link to the page. Obviously the idea is to have as many high PR pages linking to the site so we can quickly go up in search rankings, getting free targeted visitors. I have a site setup which consistently pays $1.50 per click on Adsense. It doesn't have any PR yet since I am only experimenting with PPC and haven't done any external SEO (the domain however has other pages which DO appear in search results) According to Overture, searches for this niche are done 100k times a month - it's a broad market. $1.50/click and 100k searches a month can prove to be very lucrative if external SEO is done well... (Assuming 30k hits a month at $30 CPM - I'm actually getting these results - isn't nothing for just ONE page.) I would like to attempt this experiment with people who have PR3+ pages at first to make it quick, and I guess that after a week or two Google should have the page in top 10 for our targeted keywords. Obviously, the higher the PR of your site, the higher the weight of your ad exposure. I would greatly appreciate any comments, and please PM with your site(s) so I can respond with the link etc.
