Algorithms are the strongest pillars of the “king of search engines”- Google, we all know Google is a No-1 “gigantic search engine” all over the world. The basic roots of the Google organization started with a small simple algorithm by a student.
Frequently Google implements new updates to all its working algorithms and gives a new interesting name to every update. The goal of updates is to serve better and better to its users so that to understand their requirements and provide useful appropriate information.
Google Panda was introduced in February 2011; it is a filter that lowers the rank of the thin quality sites or pages in the search engine results page. Soon after Panda roll out, many websites along with Google webmaster forum filled with number of complaints about the copyright infringers gaining better rankings than sites with original content. After that Google publicly asked about some data points to help them to detect the scrapers. Panda went through many updates since it rolled out, the effect came global in April 2011. Also Google provided advisory on its blog for self evaluation about the quality of the website. The filter is influenced by Google Quality Raters. Quality Raters answer some risky questions, so that Google can distinguish the difference between high and low quality sites.

Google Penguin is a code name for a Google algorithm update that was first announced on April 24, 2012. The update is aimed at decreasing rankings of websites that violate Google’s Webmaster Guidelines through the practice of so called “Black Hat” SEO tactics involved in increasing artificially the ranking of a webpage by manipulating the number of links pointing to the page, primarily to boost Google rankings. When newly Penguin Update was released, black hat sites were filtered from the good books of Google, and the sites that were genuinely following the Google guidelines were rewarded by good rankings.
