Analytics software indicated that one of my sites was receiving a good percentage of traffic from German, French and Spanish countries.
I optomized for it by providing a server side language translation option for just those three languages. Since doing so traffic has increased a small amount from each, perhaps 2% in the past 28 days.

In paying attention to results from translated content it became obvious that I need to fix the zero earnings clicks i'm receiving somehow. I didn't realise how much of an issue foreign visitors was for adsense until looking into the problem so i've temporarily turned off the translations.

The problem of foreign clicks has to have been addressed. I'd prefer not to swap out adsense for a foreign friendly affiliate banner or whatnot during the night hours, are there any better solutions? I'm considering registering foreign domains and duplicating the site into four languages if a good solution hasn't been found.

Ideas? I'm sure i'm missing something simple on this one.
