mslina2002 it would be very useful for us to know what you made (exactly) to restore your positions.
As I mentioned earlier, the shift didn't just happen to my site (bump in SERPs) but to the whole block of sites. This coincidence with Panda hitting Europe makes me think that this algorithmic change caused some sites before me to be dropped in the US as well. One particular competitor was ranking well in Europe and US but is now Panda-wacked from both SERPs. So perhaps my restoration was not due to my "fixes" but due to others being bumped out of the way. However, if you want me to post my fixes, I'd be happy to post my madness.
