I recently found Rory Hansen’s blog through some technorati tags and I must admit that I was quite impressed by a little study which Rory conducted over there (starting with this post). With a 50$ signup bonus budget (for 5$ deposit) Hansen started buying traffic from Yahoo ads, redirecting the visitors to his so called “conversion websites” where Google Adsense referral ads for Firefox would be waiting. A referral conversion typically gerenates a dollar income so Rory did the math and tried attracting more visitors using additional PPC programs, such as Google Adwords and MSN Adcenter by only using the income generated by the 50$ starting budget. It’s like going to the casino with 5$ and managing to leave it again with a full wallet.

Of course, the additional PPC campaigns cost additional money, but in the end it seems to add up perfectly and a nice profit margin results. Very cool, especially since he doesn’t make a secret of the profit, for example december earnings:

Google Adsense: $82.30
Firefox + Google Toolbar Referrals: $2,000.01

Yahoo! Marketing: $435.90
Google Adwords: $539.02
MSN AdCenter: $3.21

Profit: $1,104.18

If you’re into Adsense and like playing with numbers, calculating possible revenues you might really want to check Rory’s blog out.
