Search engine algorithms have been around for a long time. They have been updated to meet the requirements of the ever demanding public. Goals behind every update is to improve the algorithm with respect to the market requirements to give a more relevant and specific result to a query by the user. There are a many search engines available on the internet such as Google Search, Baidu, Yahoo, Bing, Yandex etc. Although the basic focus to return a result of most of the search engine searches are on the fundamental tags of a web page, they all have their own respective way of  Algorithm functioning. Ever since the introduction of Google Search in 1997, the worldwide market share of all search engines has been rather lopsided. Google has dominated the search engine market, maintaining an 88.2 percent market share as of 2014. In July 2014, 4.61 percent of worldwide internet users searched the web with online search engine Bing. During the same month, Chinese search engine Baidu had a market share of 0.55 percent [1]. In this document we will focus mostly on the Google search Algorithms. We will first take a brief look at the past algorithms by Google and then focus more on their most recent release Hummingbird. Past Algorithms used by Google: Google Panda: Google Panda algorithm is a change to Google's search results ranking algorithm that was first released in February 2011. Aim was to lower the ranks of low quality sites and return the high quality site to the top of  the search list. Ranking based on:-

1. Google Quality Raters asked some questions regarding a website and based on the answers Google could differentiate between high quality and low quality sites.

2. Google Panda affects the ranking of an entire site or a specific section rather than just the individual pages on a site.

3. In March 2012, Google updated Panda and stated that they are deploying an "over-optimization penalty," in order to level the playing field.

4. Content that is general, non-specific, and not substantially different from what is already out there should not be expected to rank well.

Google Penguin: Google Penguin is a search engine algorithm update that was first announced on April 24, 2012. This update was aimed at decreasing the ranking of website pages that violate the guidelines set by Google’s Webmaster.Using black-hat SEO (Search Engine Optimization) techniques involved increasing artificially and manipulating the ranking of a web page were targeted by this algorithm. Guiding principle was to target and penalize the websites who implemented such techniques like doorway pages. Doorway pages: Here pages are created to spam the index of search engine by inserting results for a particular phrase with the purpose of sending visitors to a different page. In 2012 Page-Layout algorithm was released which targeted websites with too many ads or ones with very less relevant content to offer. Google has modified and adapted very quickly to the sudden increase in Internet usage. There is a lot of competition amongst business to get a good placing in Internet searches. Google has successfully implemented its protocols regarding moderation and monitoring for Black Hat activities. Google have always strives hard to provide a better and class apart user experience with their tools. There are constant updates coming in and rest assured Google ultimate goal of providing authenticate and good results to their users which they can actually implement will surely be attained.
