Bottled Water It sounds like bottled water to me. Get it for free from the sea or for cheap from the tap, then sell it on for a higher price. A scam in many ways but works. But like I said in another thread, if there is a market then i can't hold anything against you for trying to make money out of it. But IMO just AW in, AS out won't work. Natural listings will have to help out. But if the rumours of the internet running out of adspace are true then that might fuel AS ctr commission and make it worthwile.
I have tried this scheme a couple of months ago. And the results were not good at all. Adword->Adsense. I had some free credits so I used it to run some tests and it was plainly evident that even at 5 cents a click it was not worthwhile for my site.
What is a good ROI? So far I am getting about 150% on this "scheme." Unfortunately with .05 cents a click even 1000% isn't much money, hahaha.
