Initially the Panda update was called the farmer update by the search engine marketing industry because it seemed to be targeting content farms and low quality sites that were spamming the search results. It was originally launched in February 2011 and was credited with affecting up to 12% of all search results pages. The purpose behind Google Panda was to identify low quality content vs. high quality content and was named after one of Google’s lead engineers, Navneet Panda. He instituted machine learning into the algorithm to find patterns through low quality sites and high quality sites such as how much advertising is on a site, how much duplicate content is present, how much unique content is located on a site, analytical information and page load speed. If you feel your site has been negatively affected by the Panda update, it is important to look at the content found on each page of your website. First, see if your content is unique to your site or whether it is scraped from another site. Make sure that your content is unique as possible. Look at all the content on your site and remove those which are not unique. It is important to understand that Panda is a series of updates and Google is always updating the algorithm or the ranking search factors. If you haven’t seen effects from Panda on your site yet, there is a good chance that you might see them in the future. A good content review is a great way to be sure that your site remains Panda friendly.
