After a year of Penguin there does not seem to be even a consensus if it is on page or off page?
I suspect there's no consensus because there are number of factors at play. If you are ranking #3 for a keyword, then after Penguin you are ranking #23 because you've been replaced by 20 big brand results (and I don't mean 20 individual big brands, but perhaps 7 or 8 big brands with host crowding) - a very common situation for a lot of my clients - then it's more likely "Penguin" also includes positives (for big brands) as well as negatives for smaller sites. I've also noticed that Penguin updates have a "slide" affect - you lose 2 positions 1 day, then another 2 positions 5 days later, then 3 positions 1 week later etc - it's like Google are transitioning a new SERP into place - it makes it all the more difficult to work out why things are happening that way.
