Fencer: I don't know if you work with an "ad go-between site" (don't know the right term here), but if not, you could focus ads from certain languages or certain markets (countries or states), to certain people with those characteristics. This could focus your ads to the people, and could increase your funds through these ads. However, I doubt this will work! Because I am sure you probably work directly with some one else that does the ads automatically for you! But you could always send an idea like that to them, and intergrate your system with theirs... if that would be possible, you could both make more money... just an idea. Discard if it doesn't work. :-)
