Impressions in Google SERP has declined from 3500 to 1600 after 5-25-2012\. Is it Penguin?

It's about the website

The visitors had declined from 270 to 150 visitors per day. Is this caused by the Google update Penguin? If so what can I do to solve the problem?

Thank you for your time and effort,

Hi Sebastiaan, The Google Penguin update targeted 'black hat webspam', which affected the ranking orders on some SERPs.

If your site's rankings did not drop, the change in traffic is unlikely to be connected to the Penguin update. Did you experience a drop in your rankings?

You need to have a look at your rankings and find out which keywords were driving that traffic. Once you find the keyword(s) that have fallen then you can make the assumption that it could be Penguin.

Although looking at your domain, it is an obvious keyword based domain which was cracked down on as well. Look into Analytics though before assuming Penguin.
