Google Panda is a major change to Google's search results ranking algorithm that was first released in February 2011. The change aimed to lower the rank of "low-quality sites" or "thin sites", in particular "content farms", and return higher-quality sites near the top of the search results.
CNET reported a surge in the rankings of news websites and social networking sites, and a drop in rankings for sites containing large amounts of advertising. This change reportedly affected the rankings of almost 12 percent of all search results. Soon after the Panda rollout, many websites, including Google's webmaster forum, became filled with complaints of scrapers/copyright infringers getting better rankings than sites with original content. At one point, Google publicly asked for data points to help detect scrapers better. In 2016, Matt Cutts, Google's head of webspam at the time of the Panda update, commented that "with Panda, Google took a big enough revenue hit via some partners that Google actually needed to disclose Panda as a material impact on an earnings call. But I believe it was the right decision to launch Panda, both for the long-term trust of our users and for a better ecosystem for publishers."
Google's Panda received several updates after the original rollout in February 2011, and their effect went global in April 2011. To help affected publishers, Google provided an advisory on its blog, thus giving some direction for self-evaluation of a website's quality. Google has provided a list of 23 bullet points on its blog answering the question of "What counts as a high-quality site?" that is supposed to help webmasters "step into Google's mindset".
The Google Panda patent (patent 8,682,892), filed on September 28, 2012, was granted on March 25, 2014. The patent states that Google Panda creates a ratio with a site's inbound links and reference queries, search queries for the site's brand. That ratio is then used to create a sitewide modification factor. The sitewide modification factor is then used to create a modification factor for a page based upon a search query. If the page fails to meet a certain threshold, the modification factor is applied and, therefore, the page would rank lower in the search engine results page.
Google Panda affected the ranking of an entire site or a specific section rather than just the individual pages on a site.
For the first two years, Google Panda's updates were rolled out about once a month, but Google stated in March 2013 that future updates would be integrated into the algorithm and would therefore be less noticeable and continuous.
Google released a "slow rollout" of Panda 4.2 starting on July 18, 2015.
A comparison shopping website, sometimes called a price comparison website, price analysis tool, comparison shopping agent, shopbot or comparison shopping engine, is a vertical search engine that shoppers use to filter and compare products based on price, features, reviews and other criteria. Most comparison shopping sites aggregate product listings from many different retailers but do not directly sell products themselves, instead earning money from affiliate marketing agreements. In the United Kingdom, these services made between £780m and £950m in revenue in 2005. Hence, E-commerce accounted for an 18.2 percent share of total business turnover in the United Kingdom in 2012. Online sales already account for 13% of the total UK economy, and its expected to increase to 15% by 2017. There is a huge contribution of comparison shopping websites in the expansion of current E-commerce industry.Content farm
In the context of the World Wide Web, a content farm (or content mill) is a company that employs large numbers of freelance writers to generate large amounts of textual content which is specifically designed to satisfy algorithms for maximal retrieval by automated search engines. Their main goal is to generate advertising revenue through attracting reader page views, as first exposed in the context of social spam.Articles in content farms have been found to contain identical passages across several media sources, leading to questions about the sites placing search engine optimization goals over factual relevance. Proponents of the content farms claim that from a business perspective, traditional journalism is inefficient. Content farms often commission their writers' work based on analysis of search engine queries that proponents represent as "true market demand", a feature that traditional journalism purportedly lacks.Google Hummingbird
Hummingbird is the codename given to a significant algorithm change in Google Search in 2013. Its name was derived from the speed and accuracy of the hummingbird. The change was announced on September 26, 2013, having already been in use for a month. "Hummingbird" places greater emphasis on natural language queries, considering context and meaning over individual keywords. It also looks deeper at content on individual pages of a website, with improved ability to lead users directly to the most appropriate page rather than just a website's homepage.
The upgrade marked the most significant change to Google search in years, with more "human" search interactions and a much heavier focus on conversation and meaning. Thus, web developers and writers were encouraged to optimize their sites with natural writing rather than forced keywords, and make effective use of technical web development for on-site navigation.Google Penguin
Google Penguin is a codename for a Google algorithm update that was first announced on April 24, 2012. The update is aimed at decreasing search engine rankings of websites that violate Google's Webmaster Guidelines by using now declared black-hat SEO techniques involved in increasing artificially the ranking of a webpage by manipulating the number of links pointing to the page. Such tactics are commonly described as link schemes. According to Google's John Mueller, Google has announced all updates to the Penguin filter to the public.Google Pigeon
Google Pigeon is the code name given to one of Google's local search algorithm updates. This update was released on July 24, 2014. The update is aimed to increase the ranking of local listing in a search.
The changes will also affect the search results shown in Google Maps along with the regular Google search results.
As of the initial release date, it was released in US English and was intended to shortly be released in other languages and locations. This update provides the results based on the user location and the listing available in the local directory.HubPages

Keyword stuffing is a search engine optimization (SEO) technique, considered webspam or spamdexing, in which keywords are loaded into a web page's meta tags, visible content, or backlink anchor text in an attempt to gain an unfair rank advantage in search engines. Keyword stuffing may lead to a website being banned or penalized on major search engines either temporarily or permanently. The repetition of words in meta tags may explain why many search engines no longer use these tags.
Many major search engines have implemented algorithms that recognize keyword stuffing, and reduce or eliminate any unfair search advantage that the tactic may have been intended to gain, and oftentimes they will also penalize, demote or remove websites from their indexes that implement keyword stuffing.
Changes and algorithms specifically intended to penalize or ban sites using keyword stuffing include the Google Florida update (November 2003) Google Panda (February 2011) Google Hummingbird (August 2013) and Bing's September 2014 update.List of Google April Fools' Day jokes
Google frequently inserts jokes and hoaxes into its products on April Fools' Day, which takes place on April 1.Mahalo.com
Mahalo.com was a web directory (or human search engine) and Internet-based knowledge exchange (question and answer site) launched in May 2007 by Jason Calacanis. It differentiated itself from algorithmic search engines like Google and Ask.com, as well as other directory sites like DMOZ and Yahoo! by tracking and building hand-crafted result sets for many of the currently popular search terms. President Jason Rapp exited the company in September, 2012.In 2014, Calacanis announced that Mahalo would be sunset as he moved his focus towards an app called Inside. He was quoted by TechCrunch saying "it makes 7 figures so we’re not shutting it off but we are not investing in it". Mahalo's website has since shut down.MetaFilter

In digital marketing and online advertising, spamdexing (also known as search engine spam, search engine poisoning, black-hat search engine optimization (SEO), search spam or web spam) is the deliberate manipulation of search engine indexes. It involves a number of methods, such as link building and repeating unrelated phrases, to manipulate the relevance or prominence of resources indexed, in a manner inconsistent with the purpose of the indexing system.It could be considered to be a part of search engine optimization, though there are many search engine optimization methods that improve the quality and appearance of the content of web sites and serve content useful to many users. Search engines use a variety of algorithms to determine relevancy ranking. Some of these include determining whether the search term appears in the body text or URL of a web page. Many search engines check for instances of spamdexing and will remove suspect pages from their indexes. Also, search-engine operators can quickly block the results-listing from entire websites that use spamdexing, perhaps alerted by user complaints of false matches. The rise of spamdexing in the mid-1990s made the leading search engines of the time less useful. Using unethical methods to make websites rank higher in search engine results than they otherwise would is commonly referred to in the SEO (search engine optimization) industry as "black-hat SEO". These methods are more focused on breaking the search-engine-promotion rules and guidelines. In addition to this, the perpetrators run the risk of their websites being severely penalized by the Google Panda and Google Penguin search-results ranking algorithms.Common spamdexing techniques can be classified into two broad classes: content spam (or term spam) and link spam.Squeeze page
