Nobody really knows, and if they do, they certainly aren’t informing. Google seems to have an interest in uncommon titles. The business name itself explains a complicated statistical system, which is appropriate, since the company’s strength is complicated statistical methods to enhance seo outcomes.

February 23, 2011: Google Panda/Farmer Update – When the Google Panda update founded, there was no prescribed name from Google, and then we called it the “Farmer” update. A few days after, Google assured us they internally appointed it the Panda update. So we changed names from Farmer to Panda to keep off that disarray. This update regarded up to 12 percent of search results. The update punished low quality websites, low quality content/duplicate content; generally content held not worthful to the exploiter. 
April 24, 2012: Google’s Penguin Update – After weeks of guess about an “Over-optimization penalty”, Google eventually rolled out the “Webspam Update”, which was soon after nicknamed “Penguin.” Penguin conformed a number of spam factors, including keyword stuffing, and impacted an estimated 3.1% of English queries. 
August 20, 2013: Google Hummingbird Update – Announced on September 26th, Google proposed that the “Hummingbird” update rolled out about a month before. Our best guess splices it to a MozCast spike on August 20th and lots stories of flux from August 20-22. Hummingbird has been equated to Caffeine, and looks to be a core algorithm update that may power alters to semantic search and the Knowledge Graph for months to come. 
Jul 25, 2014: Google Pigeon Update – Pigeon is the name we resolved on since this is a local search update and pigeons incline to fly back home. This is not actually a spam vary but more of a key change to the local search ranking algorithm.
