My site was hit by Panda 1.0 (US ecommerce affiliate). I'm noticing a huge shift in traffic patterns for the past few days. Most of this traffic does not convert at all - most of the terms are long tail and I am seeing an almost complete shift day to day for the various keywords driving traffic. My overall traffic has been relatively consistent - but most of it feels like junk / non-targeted traffic.
My money is on this being a Panda update as well for this multi-week update. My site will typically get this junk traffic right at the start of the last few Panda updates, but it usually clears out and returns to a consistent baseline after a couple of days. This feels like it is going to take a lot longer to (hopefully) return to a baseline of non-junk traffic.
I am also seeing a huge spike in WMT crawling - which may or may not correspond to this update.
