History

Historical Context

In February 2011 Google released the Panda algorithm, created by engineer Navneet Panda, to demote low-quality sites and improve search results. The update went global in April, hit about 12 % of results, and prompted monthly rollouts for two years before being folded into the core algorithm in 2015. Its impact led Google’s webspam chief Matt Cutts to acknowledge the trade-off between short-term traffic loss and long-term trust.
