Hi Marie! I loved your recent post about the difference between Panda, Penguin and Unnatural Link Penalties recently.
First off, I'd like to say that I'm still getting awesome results with my SEO. I work on around 100 websites, and both my on-site and off-site techniques are improving the results.
That being said, I can see that the site level metrics are having a larger influence. I work in a niche that has lots of different providers for websites, and most of them create tons of duplicate content. The sites that are creating 1000's of pages of duplicate content have been hit hard in the past 6+ months, and it's getting harder to keep them ranking well, but the one's with great architecture are actually getting easier.
For a great example of a company taking the initiative on this I'd look at Autotrader. They recently, within the last year I believe, decided to no-index all of their inventory. They did this because all of it was the exact duplicate of what the dealers had posted in dozens of other places online. Right after they made that change I saw a dramatic improvement in rankings across the board.
