I was just wondering the success rate of Google Adsense ads on pages where English is not the main language used. i.e. websites in French...

1. Do English ads appear for the equivalent French keyword i.e. does Google do the translation from French to English and the appropriate advertisers English advert appear?

or...

2. Do French ads appear for French keywords

or...

3. Do a mixture of English and French ads appear depending on whether or not English or French advertisers have bid for the highest keyword/phrase?

and....

4. If I used a "translation button" on my English website, (to convert it to French) - what kind of ads would appear in the French version?

I'd be interested to know if anyone has had experience of this, as I'm thinking about developing a couple of multi-lingual websites in the not too distant future.
