Penguin hit | Immediate?

[godreamvacations]

Last year we fell off google rankings fairly quickly (mid-2013), out of the blue. We thought it was Penguin; but after looking at Analytic data of organic google visits; there seems to be no drastic loss of traffic at any time. Our site's loss of traffic is a gradual decline, not immediately noticeable, as in this video (~33:00 minutes in ). If there is no drop in organic google traffic that's noticeable, can I safely assume our drop in rankings wasn't due to an algorithm update?

I don't have the expertise to answer this question, but am wondering if it should be part of your other question at http://moz.com/community/q/cleaning-up-after-penguin-next-steps or if it is a separate question? It can be helpful to have just one conversation going about a topic instead of two. If you'd like to combine them, let me know, and I'll lock comments on this question and you can edit and add this to your other question.

I think the length of my other question might be turning people away. This question is more direct.

I would expect penguin to be sudden.
What your problem sounds like to me, is slowly your links are being discounted as google finds them. Do you have a lot of rubbish links?
