Google Panda is a change to Google’s search results ranking algorithm that was first released in February 2011. The change aimed to lower the rank of “low-quality sites” or “thin sites” and return higher-quality sites near the top of the search results. CNET reported a surge in the rankings of news websites and social networking sites, and a drop in rankings for sites containing large amounts of advertising.This change reportedly affected the rankings of almost 12 percent of all search results. Soon after the Panda rollout, many websites, including Google’s webmaster forum, became filled with complaints of scrapers/copyright infringers getting better rankings than sites with original content. At one point, Google publicly asked for data points to help detect scrapers better. Google’s Panda has received several updates since the original roll out in February 2011, and the effect went global in April 2011. To help affected publishers, Google published an advisory on its blog,thus giving some direction for self-evaluation of a website’s quality. Google has provided a list of 23 bullet points on its blog answering the question of “What counts as a high-quality site?” that is supposed to help webmasters “step into Google’s mindset”


Google Panda was built through an algorithm update that used artificial intelligence in a more sophisticated and scalable way than previously possible. Human quality testers rated thousands of websites based on measures of quality, including design, trustworthiness, speed and whether or not they would return to the website. Google’s new Panda machine-learning algorithm was then used to look for similarities between websites people found to be high quality and low quality.

Google Penguin is a code name for a Google algorithm update that was first announced on April 24, 2012. The update is aimed at decreasing search engine rankings of websites that violate Google’s Webmaster Guidelines by using now declared black-hat SEO techniques, such as keyword stuffing, cloaking, participating in link schemes, deliberate creation of duplicate content, and others. Unlike PageRank, however, Google makes all updates to this algorithm public.

While Penguin was technically an algorithm update, it wasn’t really a change in how Google factors ranking; it was just the official word that Google is taking action against people trying to game the search system. Simply put, Penguin targeted web spam. So, if you were playing by the rules, you shouldn’t have been affected.

Take a look at a snapshot from my company’s analytic s. The first line is Panda 2.5. We had somewhere in the neighborhood of 5-digits worth of duplicate content. We corrected it and started heavily playing by Google’s rules
