There must be someone at Google who likes black and white animals. One of the latest updates to the Google search algorithm is named Penguin. This isn't to be confused with Panda which is another update to the way Google searches and indexes traffic.
You are asking this question 'What is google penguin?' but in your signature you are offering Seo services etc i think you are having a laugh !!
It is the new google algorithm (webspam update) to discourage the spammers and black hat webmasters and SEO.
My God Digitalpoint is overrun with spam and terribly low quality posts. Has it always been like this? A quick Google is all you'll need to find the answer. To be honest this seems more like an effort to relate the Google Penguin keyword to the links in your signature.
The Penguin update was released April 24, 2012 with the goal of eliminating most blog networks that are linking to each other. Its goal is to eliminated 'artificial' backlinks and counts only authentic backlinks pointing to a site. What is authentic? Websites that found the site valuable will be linking to it. But it is really nothing to worry about if you have not violated the rules.
It'll give the penalty of -150 to -200, and DE-indexed your website from Google search engine. According to my research, Penguin just hit those websites who use the keyword stuffing in their On-Page SEO, but 1 more thing...now a days Penguin and panda both are in action and don't make the poor link to your website. Try to get the quality links to your website, in which unique content links and link from high website make your website more visible and help to get ranked instantly.
