A member posted a thread at WebmasterWorld in the Microsoft adCenter forum asking how he can advertise in the German market with adCenter. Guess what? You can't, not just yet.
However, adCenterEU, the official Microsoft representative in the European market, told this member to advertiser with Yahoo Search Marketing. He said:
It's true that adCenter is not available in Germany as yet, so i suggest you go through our paid search partner Yahoo! Search Marketing.
From the UK just sign up here:
Pretty cool! Well, I assume as soon as Microsoft expands into Germany, those recommendations will halt.
