Google Panda and Google Penguin- Ratings and Sanctions Search tools use search quality measurement, ranking algorithms, penalty algorithms, and manual penalties. Sanctions and penalties can cause a big change in organic search. Google's Panda algorithm was created on February 23, 2011. The algorithm focused on analysing the quality of web content. Panda was designed to lower the rankings of low-quality websites and increase the rankings of high quality, original content websites. There was a big change in search and the algorithm affected 10% of all Google searches. The algorithm penalizes thin content, content farms, sites with poor quality content, etc. The Google Penguin algorithm began on April 24, 2012. An important algorithm aimed at solving poor quality links in the Google search engine. The algorithm penalizes many different, bad types of links such as spam commenting, link farms, buying links, etc. Every year, Google changes the Panda and Penguin algorithmic updates that most affect a site 's search engine rankings.
