What is Google Panda

Google launched Panda in February 2011, mainly as a change in its search results ranking algorithm. The main purpose of the update was just to keep those low quality and low content sites away from the top ranking results and give the actual quality sites their due.

As an obvious result, many websites with huge amount of advertising, or those with low quality content, saw a huge decline in the rankings. Ever since Panda was launched, there have been many updates to it ranging to over 22 in total.

Google Penguin refers to a set of algorithm updates and data refreshes for the Google search engine that the company periodically initiates to help enhance the value of its search query results for users.

The Google Penguin updates primarily seek to prevent various types of search engine spam (also known as spamdexing or Black Hat SEO) from being successfully rewarded in the form of higher-placed search engine results. Search engine spam can include activities such as keyword stuffing, link spamming, the use of invisible text on web pages, duplication of copyrighted content from high-ranking web sites and more.

Google doesn’t always announce changes for Penguin, but there have been at least five Google Penguin updates, including a major update, Penguin 2.0, in May 2013 and the most recent, Penguin 2.1, later that year in October.
