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 2nd 2012 and this algorithm was updated on 19th and 24th April 2012. Please give your valuable suggestions. Thanks
well, if your keywords went down in ranking since penguin launch, then it is clear that they were hit by penguin. you do have statistics that come with your hosting account. you can check there as well.
