Thanks tedster, I will try to get more variaty to my backlink-profiles.
A site that was ranking fine for several keywords moved from the first page to the third page. It seems to me like a small penalization: most of the page had been cached two-three days ago.
Thats exactly what I see without any hint of "why" and no overoptimization was done here (on some sites nothing was done for month). Some of them are coming back, some are better then before, but some are still just "gone" - no matter if it's a money keyword or if you just needed 4 links to get to the top.
