Adsense for Indic language websites

I tried Adsense for my Tamil blog and the result is a disaster :) I had thousands of impressions and only one click worth 1 cent !! It mostly showed public service ads or irrelevant links or went blank.

What publishers can do:

* Even if your content is non-English, name your domain relevantly in English. The ads do match the domain name when the content is not English.

* Try giving tags, categories, post titles, post summary in English. This can be only done while annoying the intended native audience.
