Also, only a minority of sites get hurt by Panda. Your site may be helped when it hits your area. Look for a small but sustained increase in traffic - small because the gains are spread out over a lot more sites than the dramatic losses that we have analyzed over the past weeks.
And many sites just keep on plugging along after Panda hits their area. That's the way it's been for the majority of the sites I work with. Their traffic profile is not be in those query areas that are impacted very much. In fact, the SERPs for their most important query terms have barely jiggled, nothing noticeably different than the normal everflux.
