Tremendous changes today. SERPS are in flux. On my employers site the traffic is still high but it's all wrong. Everyone we talk to in unrelated businesses reports high traffic terrible quality.
Two word keywords are driving a ton of traffic. Long tail is not. I cannot tell if it's related to google suggest or the change. Bounce rate is up 15% over April when orders are converting. A b2c site jumped from 32% to 60% on Sunday and it's stayed 50-60% for the last 36 hours.
I agree with those that say don't change anything. The hit some of you took may have just been the prelude and the real spam hit is occurring now.
