Definitely a niche topics... The issue is with Googling will most likely to bring back USA/UK websites, and not the tons of Russian, Spanish and Chinese related websites on the same niche topic which still bring in loads of traffic. Missing out quite a bit of cheap traffic there. Anyone got any idea how to solve this? Most of the time, I will use site:.eu or site:.co.jp to limit the search, but then again, it is not in its native language/context, the results are often not relevant. :(
