BeeDee, I am not sure how familiar you are with in regards to panda. Of all the theories that have come out, ads seem to be the one mentioned the most.
Just do a search for "google panda adsense".
The day panda was release a member here even noticed that adsense had changed their best practice guide.
A site that overwhelms you with ads, makes it extremely hard to find any actual content, should a site like that rank well? I certainly don't think so.
