The Inside AdSense Blog announced support for Greek and Romanian publishers to place AdSense on their site. The ads will then target Greek and Romanian advertisers in Greek and Romanian languages.
In addition, Romanian publishers (not Greek) can add AdSense for Search to their site.
How do you do it?
If you're ready to get started with these languages, just log in to your AdSense account and follow the wizard located under the AdSense Setup tab. You can also contact the Greek team at firstname.lastname@example.org and the Romanian team at email@example.com with additional questions.
DigitalPoint Forums has some early feedback on this release.
The English version looks tidier and the CPM explanation in Romanian sounds weird so I'll stick to English for now.
It's not really worthy making a romanian site with romanian ads on it. you'll only get $0.01/click unless it is Real Estate or Travel site where you get $0.05.
