I'd agree with synthese. I don't find that certain pages or subdirectories were necessarily hit differently.
I do see a larger percentage traffic loss on some pages that ranked in the top #5 for certain keywords. But that is what you would expect. We all know top ranking positions get a higher percentage of clicks, and therefore when they drop they loose a proportionally larger percentage of traffic. A drop from #1 to #25 will loose more proportionally than a drop from #10 to #35. It's not arithmetic.
But for my individual subdirectories as a whole, topics that were basically long-tail pages and not high rankers, the drop in traffic is essentially the same percentage.
I wish it was so easy as to look at Analytics and see which pages google no longer valued.
