Hi there,
You're always welcome to hijack a thread if you post 'namedrive rocks' at the bottom
Seriously though, we have a very strong German presence and I can certainly have our team look over your portfolio for you to get the most out of it. Having looked at the CS mails, I believe I may know who you are already - with a hotel domain showing English ads... - but if you send me a PM with your account email, then I'll be glad to get it seen to. I'm half-German myself, so I can have a look and make sure things are OK for you.
I'm not a big fan of 'normal' CTR. Every company counts views and clicks differently and some try to make CTR perhaps look higher than the earnings would suggest. Yahoo feeds can have multiple clicks from single IP addresses, meaning over-100% CTRs in some cases. We like to focus on earnings at the end of the day. If you're earning more, then people are generally happier. However, for German traffic, we generally manage to get around 20% CTR on the names, this can go anything up to 50/60% on very targeted names, so I certainly think there is some distance to grow. If you get in touch, then I'll be glad to have the German team look over it.
I look forward to hearing from you.
Ed
