Can't find my News with Google

Hello,
I have already replied to this thread but no one replied so I am just creating a new thread here.

I got 2 sites which work with CutePHP.
The first domain is kag2d.de and I can find the news if I google for them.
The second domain is dar-dar.de/Blog but I can't find any news with google.
Lets take this as an example. If I search for the News title I can not find it.

Any idea why that's happening?

Regards darDar
