Damn traffic...

Anyone got a solution to my problem? Currently I am targetting 3 competitive kws in software niche. 2 of them have about 40 000 exact searches and according to my tools ( rankerizer and eastern european tool) and 2 of them are in top 10 in g.com and last one is 15/ 17. I obviously know that I will not get about 100 000 visitors a month but what frustrates me i get in total of all of them less than even 1000!

so where is the problem than?
- measuring tools?
- geolocalization? (website is hosted in DE not US)
- website?
- meta tag?

Any wise head comments much appreciated.

cheers,
