HuskyPup, what other elements do you have on your homepage/site in addition to Adsense?
Adsense ad units appear to be fine with Panda across all the sites which I manage. However, combine that with an Aweber subscription form (one of my sites gives stuff away to registered subscribers) and an Amazon Associate link equates to an overnight drop from #2 to #13 for its primary keyword. The total number of words on this particular site's homepage is 774.
Another site I manage, which is in the automotive e-commerce niche, sits at #4 for its primary product. This product page has over 500 links pointing to the page whereas those above the listing have 1 to 5 backlinks. The top listing has a single backlink from ebay.co.uk, which is a non-editorial link from their eBay store in the UK. Keep in mind that unlike the others above this listing, ours has a full schematic and application data specifically so that consumers may determine if the product is right for them without having to pick up the phone and call. If content were king, we would rule. Instead, preference is given to non-editorial links and brand/domain authority. Pre-Panda this page ranked better and received more sales. But ironically, those listed above this product are all major spenders on Google Adwords.
Newer sites under my management appear to be more susceptible to each Panda tweak. Domain age, despite the number and quality of backlinks, appears to be a major consideration for Panda.
What Panda appears to be is a funnel designed to drive traffic to those websites which Google has an interest in. Especially in a depressed economy, Google's growth has been substantial. This does not happen in an *equal* playing field. Come to your own conclusions after reviewing the winners and losers with each Panda update.
