Hello Friends hope you fine after latest panda updating 27 September 2012. This week after panda update my sites keywords have been very down (which is very shocking for me). Before latest panda updating my sites keywords are on the first page of Google search results but after latest updating all keywords are down even not showing in 200 positions.
Can anybody tell me what the reason and how long it takes that my keyword on same ranking? I have removed all the duplicate content, made new unique posts, continued back linking but keywords are still down and also explain me what is over optimization!
We are building 90% approved 170 to 200 links. Is it considered over optimization? If it is, so what should I do and what are your recommendations for panda solution and daily link building activities.

Can't predict the time period, but I would recommend you to keep working on getting quality links for your website after adding fresh content.

But I feel, you would see positive results within 1 month.
