For the month of April one of the small apps that I sell for £25 made me over $200 in Rockyou ad revenue (I will post proof shortly).
That is just from ONE application and it isn’t even one of the big apps. And I’ve done zero promotion on it, that is all viral traffic. When these things take off – they take off. I’ve cleared $20 already in the first two days of this month from the same app.
I will put my prices up soon. Where else online can you buy something that can show a return that quickly?
