But it would be interesting and revealing to know why a site escaped 1.0 and was caught in 2.1.
I think it was the type of keyword. Panda 1 sites ranked for the trophy one word and two word keywords. Panda 2.1 sites ranked for three word keywords and long-tails.
Panda 2.1 sites were less important in G's eyes as they were sending less traffic to them.
