Analytic implemented after Google penguin was introduced.

[IntegratedS]

I have confusion, that whether my site was hit by Google penguin or not because my site keywords are facing a major drop since the penguin was launched. But I do not know how to track this because Google analytic was implemented on May 2^nd 2012 and this algorithm was updated on 19^th and 24^th April 2012.

Please give your valuable suggestions.

Thanks
