Ads in languages other than English paying bad?

[DXL]

I have a niche news site that is in English, with about 3% of the pages in Spanish. I recently added a page in Spanish relating to a recent event, and traffic for the page has been incredible due to its positions in the SERPS.

However, I noticed that the Adsense ads are in Spanish (including the "ads by google" reference). I created a separate channel for that page, and realized that instead of getting my usual 5-10 cents per click, its only paying out 1 cent per click. Is it because the content and subsequent ads are in Spanish? Any way I can improve performance?

I have ads running in my native language (Dutch).
It appears there is not so much Adwords competition yet in my language. That means that prices of clicks remain low...

Yes, competition plays an important role. However, note that there's a limit to this; at some point advertisers cannot push the price up anymore because it simply becomes unprofitable. In other words, prices of clicks in underdeveloped countries will never be equal to American ones. After all, it would be stupid to expect e.g. a Chinaman to buy as eagerly as an American - it's all about it, isn't?
