Humble pie for me! I still have pages that rank really well, but many slipped in latest update.
Why do you think there's not enough data for number 2?
OK, so more about us (in the interests of spotting the problem)...
We are e-commerce and always write our own content and take our own photos (OK < 1% mfr's photos).
If there's one thing that makes us standout (maybe our problem?), it's that we typically write rather more than our competitors. Have untypically long content for sector.
Our blog seems to be unaffected by panda, though it's on the same domain but in a discrete folder.
Our category pages have lots of content, first up in document order (but lurking in side bar), arranged in paragraphs, with inline links.
Our product pages have a lot more words on them than competitors. They also use a template, so generic content across pages and some laziness in just rewriting a similar product.
We wrote articles, some of which were picked up by local radio and even CNN (eventhough we're UK), but many of which have been scraped to some extent or another.
We allowed 20,000 search pages (only when good match shows) to be indexed (my bad Google, I'm sorry!). These had terrible bounce rates (90-odd %) but we thought we needed them to be a 'big' site.
We're hosted on Rackspace on a dedicated server, same ip and host for 5 years.
We're McAfee secure (since it was Hackersafe), use Verisign Extended Validation (that's the sexy green bar) certicates and have one of the obligatory safe shopping logos prominent in the UK.
Design-wise, the sites not the prettiest, but not the ugliest. It's certainly not hobby-like. Looks professional. We have used website optimiser extensively to make the best of my average design skills and have run a lot of tests. We do have fantastic, cut out photography that is well above average for our sector.
We have our own CMS, running on XSL transforms (server side) that means we can change our pages anyway we like to improve user experience and frequently do.
Our site is considered medium speed by Google; fast by Alexa (go figure).
We have verified the site in Webmaster tools and provide a feed for Googlebase (where we do well for product searches).
We spend between £500 to £5000 (worst case, rarely) a month on Adwords.
We don't run adsense on this site; we have disguised affiliate links on two pages out of several thousand. This is where we no longer sell that product category.
We've been online since 2003. Never bought a link and haven't participated in link exchanges for 6 years or more.
We don't have tonnes of spamming back links. We've done a little article marketing, but it's a drop in the ocean. And the same doesn't seem to have done my unpandalized sites any harm at all.
All I can think is that number 1 in my original theories has us looking too much like a content website (and not enough like commerce) and our content isn't goog enough.
