ckissi, I'm looking for an explanation and an advice, that's why I've posted here. As far as I know a penalized site will not appear on first position for any keyword and in most cases for it's own domain name. This not what is happening to my site - it's on first page for some of my keywords, but for most of them the site now is on 2nd, 3th and even 18th. The other thing that bother me is that the situation repeats after 2 weeks of great traffic - some kind of a yo-yo effect which I presume has something to do with the algo update?!?!
