The client ecommerce site that I relaunched in September doesn't seem to have been affected in the slightest. Been pouring over Analytics, rankings, Raven Tools reports, and nothing seems to have changed (of course, it's early yet)
We're working on fleshing out product and category text, and writing like human beings, but I'd say right now it's probably 35/65 as a percentage of good content to thin content. No MFR content, the thin stuff is mostly just bulleted features which we put in ourselves.
We do NOT have much of a link profile on this B2B site. I've had control over this site for 14 yrs, and I'm not much of a linkbuilder; about all we have is a couple dozen paid directory inclusions on "Niche Industry Vendor/Supplier" type sites, which we bought for exposure and traffic, and most of which I think are nofollowed. Apart from that, most of our inbound links are actually on people's intranets, so not visible to search engines. We do get scraped a fair amount, but so far as I can tell, I've never found a scraper showing up above us.
The site was built on a Magento platform, and I spent six weeks writing custom titles and meta description tags for over 3000 pages. So *those* are unique.
Search (organic & ppc, Google, Yahoo & Bing) makes up about 53% of our web traffic; this company has always been a catalog company, and we're doing a healthy amount of email marketing now too, and dipping our toes in social.
I dunno if any of that helps, but add it to the pile of data.
