Is My site seeing a Google Dance ? - Rankings all over the place

[SarahCollins]

My eCommerce website is seeing some rankings flucuate daily from say rank 20 to rank 130 whilst some other keywords ago up and down by as much as 40 places.

I have been putting up alot of new unique content and can see in GWT that google has been crawling my site more but given that I was affected by the google panda updates which saw a 40% drop in traffic I'm only just to recover some of it.,

i have also been trying to get rid of any poor links and our linking building is only concentrating on high quality posts and links.

I am wondering if this is the post panda update - "google dance" or is google having issues trying to work where to rank my site and possibly punish me?

thanks

Sarah.
