Kristi Kellogg interviews Bruce Clay on the much-anticipated Penguin 2.0 update: Bruce Clay on Expecting and Escaping Google Penguin's Wrath.
Among his predictions, Bruce expects the update to roll out before SMX Advanced (i.e., early June) as that is Google's m.o. with timing their updates, and is quoted as saying "...only the top ten sites of ten million will not feel the wrath of Google."
Clay also says "I would bet money that Google rolls out multiple releases together intentionally" so as to confound spammers.
He says a number of interesting things...good interview!
