Google Panda
Google's Panda received several updates after the original rollout in February 2011, and their effect went global in April 2011. To help affected publishers, Google provided an advisory on its blog,[6] 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".[7] It has been incorporated in Google's core algorithm since 2015.[8]
The name "Panda" comes from Google engineer Navneet Panda, who developed the technology that made it possible for Google to create and implement the algorithm.[9][4]
Ranking factors
The Google Panda patent (patent 8,682,892), filed on September 28, 2012, was granted on March 25, 2014. The patent states that Google Panda creates a ratio with a site's inbound links, and reference queries, search queries for the site's brand. That ratio is then used to create a sitewide modification factor. The sitewide modification factor is then used to create a modification factor for a page based upon a search query. If the page fails to meet a certain threshold, the modification factor is applied and, therefore, the page would rank lower in the search engine results page.[10]
Google Panda affected the ranking of an entire site or a specific section, rather than just the individual pages on a site.[11]
Updates
For the first two years, Google Panda's updates were rolled out about once a month, but Google stated in March 2013 that future updates would be integrated into the algorithm and would therefore be continuous and less noticeable.[12][13]
Google released a "slow rollout" of Panda 4.2 starting on July 18, 2015.[14]
