Google Search, also referred to as Google Web Search or simply Google, is a web search engine developed by Google LLC. It is the most used search engine on the World Wide Web across all platforms, with 92.74% market share as of October 2018, handling more than 3.5 billion searches each day.
The order of search results returned by Google is based, in part, on a priority rank system called "PageRank". Google Search also provides many different options for customized search, using symbols to include, exclude, specify or require certain search behavior, and offers specialized interactive experiences, such as flight status and package tracking, weather forecasts, currency, unit and time conversions, word definitions, and more.
The main purpose of Google Search is to hunt for text in publicly accessible documents offered by web servers, as opposed to other data, such as images or data contained in databases. It was originally developed by Larry Page and Sergey Brin in 1997. In June 2011, Google introduced "Google Voice Search" to search for spoken, rather than typed, words. In May 2012, Google introduced a Knowledge Graph semantic search feature in the U.S.
Analysis of the frequency of search terms may indicate economic, social and health trends. Data about the frequency of use of search terms on Google can be openly inquired via Google Trends and have been shown to correlate with flu outbreaks and unemployment levels, and provide the information faster than traditional reporting methods and surveys. As of mid-2016, Google's search engine has begun to rely on deep neural networks.
Competitors of Google include Baidu and Soso.com in China; Naver.com and Daum.net in South Korea; Yandex in Russia; Seznam.cz in the Czech Republic; Yahoo in Japan, Taiwan and the US, as well as Bing and DuckDuckGo. Some smaller search engines offer facilities not available with Google, e.g. not storing any private or tracking information.
Within the US, as of July 2018, Microsoft Sites handled 24.2 percent of all search queries in the United States. During the same period of time, Oath (formerly known as Yahoo) had a search market share of 11.5 percent. Market leader Google generated 63.2 percent of all core search queries in the United States.

Google indexes hundreds of terabytes of information from web pages. For websites that are currently down or otherwise not available, Google provides links to cached versions of the site, formed by the search engine's latest indexing of that page. Additionally, Google indexes some file types, being able to show users PDFs, Word documents, Excel spreadsheets, PowerPoint presentations, certain Flash multimedia content, and plain text files. Users can also activate "SafeSearch", a filtering technology aimed at preventing explicit and pornographic content from appearing in search results.
Despite Google search's immense index, sources generally assume that Google is only indexing less than 5% of the total Internet, with the rest belonging to the deep web, inaccessible through its search tools.
In 2012, Google changed its search indexing tools to demote sites that had been accused of piracy.
In August 2009, Google invited web developers to test a new search architecture, codenamed "Caffeine", and give their feedback. The new architecture provided no visual differences in the user interface, but added significant speed improvements and a new "under-the-hood" indexing infrastructure. The move was interpreted in some quarters as a response to Microsoft's recent release of an upgraded version of its own search service, renamed Bing, as well as the launch of Wolfram Alpha, a new search engine based on "computational knowledge". Google announced completion of "Caffeine" on June 8, 2010, claiming 50% fresher results due to continuous updating of its index.
In October 2016, Gary Illyes, a webmaster trends analyst with Google, announced that the search engine would be making a separate, primary web index dedicated for mobile devices, with a secondary, less up-to-date index for desktop use. The change was a response to the continued growth in mobile usage, and a push for web developers to adopt a mobile-friendly version of their websites. In December 2017, Google began rolling out the change, having already done so for a few websites.
In August 2018, Danny Sullivan from Google announced a broad core algorithm update. As per current analysis done by the industry leaders SearchEngineWatch and SearchengineLand, the update was to drop down the medical and health related websites that were not user friendly and were not providing good user experience. This is why, the industry experts named it "Medic".
Google reserves very high standards for YMYL (Your Money or Your Life) pages. This is because misinformation can affect users financially, physically or emotionally. Therefore, the update targeted particularly those YMYL pages that have low-quality content and misinformation. This resulted in the algorithm targeting health and medical related websites more than others. However, many other websites from other industries were also negatively affected.
Google Search consists of a series of localized websites. The largest of those, the google.com site, is the top most-visited website in the world. Some of its features include a definition link for most searches including dictionary words, the number of results you got on your search, links to other searches (e.g. for words that Google believes to be misspelled, it provides a link to the search results using its proposed spelling), and many more.
Google search accepts queries as normal text, as well as individual keywords. It automatically corrects misspelled words, and yields the same results regardless of capitalization. For more customized results, one can use a wide variety of operators, including, but not limited to:
OR– Search for webpages containing one of two similar queries, such as marathon OR race
-(minus sign) – Exclude a word or a phrase, such as "apple -tree" searches where word "tree" is not used
""– Force inclusion of a word or a phrase, such as "tallest building"
*– Placeholder symbol allowing for any substitute words in the context of the query, such as "largest * in the world"
..– Search within a range of numbers, such as "camera $50..$100"
site:- Search within a specific website, such as "site:youtube.com"
define:– See a definition of a word, such as "define:phrase"
stocks:– See the stock price of investments, such as "stocks:googl"
related:- Find webpages related to specific URL addresses, such as "related:www.wikipedia.org"
cache:– Highlights the search-words within the cached pages, such as "cache:www.google.com xxx" shows cached content with word "xxx" highlighted.
@- Search for a specific word on social media networks, such as "@twitter"
Google applies query expansion to submitted search queries, using techniques to deliver results that it considers "smarter" than the query users actually submitted. This technique involves several steps, including:
Google's homepage includes a button labeled "I'm Feeling Lucky". This feature originally allowed users to type in their search query, click the button and be taken directly to the first result, bypassing the search results page. With the 2010 announcement of Google Instant, an automatic feature that immediately displays relevant results as users are typing in their query, the "I'm Feeling Lucky" button disappears, requiring that users opt-out of Instant results through search settings in order to keep using the "I'm Feeling Lucky" functionality. In 2012, "I'm Feeling Lucky" was changed to serve as an advertisement for Google services; users hover their computer mouse over the button, it spins and shows an emotion ("I'm Feeling Puzzled" or "I'm Feeling Trendy", for instance), and, when clicked, takes users to a Google service related to that emotion.
Tom Chavez of "Rapt", a firm helping to determine a website's advertising worth, estimated in 2007 that Google lost $110 million in revenue per year due to use of the button, which bypasses the advertisements found on the search results page.
During Google's developer conference in May 2013, the company announced that, on Google Chrome and Chrome OS, users would be able to say "OK Google", with the browser initiating an audio-based search, with no button presses required. After having the answer presented, users can follow up with additional, contextual questions; an example include initially asking "OK Google, will it be sunny in Santa Cruz this weekend?", hearing a spoken answer, and reply with "how far is it from here?" An update to the Chrome browser with voice-search functionality rolled out a week later, though it required a button press on a microphone icon rather than "OK Google" voice activation. Google released a browser extension for the Chrome browser, named with a "beta" tag for unfinished development, shortly thereafter. In May 2014, the company officially added "OK Google" into the browser itself, though the company removed it in October 2015, citing low usage, though the microphone icon for activation remained available. In May 2016, 20% of search queries on mobile devices were done through voice.
"Universal search" was launched by Google on May 16, 2007 as an idea that merged the results from different kinds of search types into one. Prior to Universal search, a standard Google search would consist of links only to websites. Universal search, however, incorporates a wide variety of sources, including websites, news, pictures, maps, blogs, videos, and more, all shown on the same search results page. Marissa Mayer, then-vice president of search products and user experience, described the goal of Universal search as "we're attempting to break down the walls that traditionally separated our various search properties and integrate the vast amounts of information available into one simple set of search results.
In June 2017, Google expanded its search results to cover available job listings. The data is aggregated from various major job boards and collected by analyzing company homepages. Initially only available in English, the feature aims to simplify finding jobs suitable for each user.
In May 2009, Google announced that they would be parsing website microformats in order to populate search result pages with "Rich snippets". Such snippets include additional details about results, such as displaying reviews for restaurants and social media accounts for individuals.
In May 2016, Google expanded on the "Rich snippets" format to offer "Rich cards", which, similarly to snippets, display more information about results, but shows them at the top of the mobile website in a swipeable carousel-like format. Originally limited to movie and recipe websites in the United States only, the feature expanded to all countries globally in 2017.
The Knowledge Graph is a knowledge base used by Google to enhance its search engine's results with information gathered from a variety of sources. This information is presented to users in a box to the right of search results. Knowledge Graph boxes were added to Google's search engine in May 2012, starting in the United States, with international expansion by the end of the year. The information covered by the Knowledge Graph grew significantly after launch, tripling its original size within seven months, and being able to answer "roughly one-third" of the 100 billion monthly searches Google processed in May 2016. The information is often used as a spoken answer in Google Assistant and Google Home searches. The Knowledge Graph has been criticized for providing answers without source attribution.
In May 2017, Google enabled a new "Personal" tab in Google Search, letting users search for content in their Google accounts' various services, including email messages from Gmail and photos from Google Photos.
The Google feed is a personalized stream of articles, videos, and other news-related content. The feed contains a "mix of cards" which show topics of interest based on users' interactions with Google, or topics they choose to follow directly. Cards include, "links to news stories, YouTube videos, sports scores, recipes, and other content based on what [Google] determined you're most likely to be interested in at that particular moment." Users can also tell Google they're not interested in certain topics to avoid seeing future updates.
The Google feed launched in December 2016 and received a major update in July 2017. As of May 2018, the Google feed can be found on the Google app and by swiping left on the home screen of certain Android devices.
Google's rise was largely due to a patented algorithm called PageRank which helps rank web pages that match a given search string. When Google was a Stanford research project, it was nicknamed BackRub because the technology checks backlinks to determine a site's importance. Other keyword-based methods to rank search results, used by many search engines that were once more popular than Google, would check how often the search terms occurred in a page, or how strongly associated the search terms were within each resulting page. The PageRank algorithm instead analyzes human-generated links assuming that web pages linked from many important pages are also important. The algorithm computes a recursive score for pages, based on the weighted sum of other pages linking to them. PageRank is thought to correlate well with human concepts of importance. In addition to PageRank, Google, over the years, has added many other secret criteria for determining the ranking of resulting pages. This is reported to comprise over 250 different indicators, the specifics of which are kept secret to avoid difficulties created by scammers and help Google maintain an edge over its competitors globally.
In a potential hint of Google's future direction of their Search algorithm, Google's then chief executive Eric Schmidt, said in a 2007 interview with the Financial Times: "The goal is to enable Google users to be able to ask the question such as 'What shall I do tomorrow?' and 'What job shall I take?'". Schmidt reaffirmed this during a 2010 interview with the Wall Street Journal: "I actually think most people don't want Google to answer their questions, they want Google to tell them what they should be doing next."
In 2013 the European Commission found that Google Search favored Google's own products, instead of the best result for consumers' needs. In February 2015 Google announced a major change to its mobile search algorithm which would favor mobile friendly over other websites. Nearly 60% of Google searches come from mobile phones. Google says it wants users to have access to premium quality websites. Those websites which lack a mobile friendly interface would be ranked lower and it is expected that this update will cause a shake-up of ranks. Businesses who fail to update their websites accordingly could see a dip in their regular websites traffic.
Because Google is the most popular search engine, many webmasters attempt to influence their website's Google rankings. An industry of consultants has arisen to help websites increase their rankings on Google and on other search engines. This field, called search engine optimization, attempts to discern patterns in search engine listings, and then develop a methodology for improving rankings to draw more searchers to their clients' sites. Search engine optimization encompasses both "on page" factors (like body copy, title elements, H1 heading elements and image alt attribute values) and Off Page Optimization factors (like anchor text and PageRank). The general idea is to affect Google's relevance algorithm by incorporating the keywords being targeted in various places "on page", in particular the title element and the body copy (note: the higher up in the page, presumably the better its keyword prominence and thus the ranking). Too many occurrences of the keyword, however, cause the page to look suspect to Google's spam checking algorithms. Google has published guidelines for website owners who would like to raise their rankings when using legitimate optimization consultants. It has been hypothesized, and, allegedly, is the opinion of the owner of one business about which there have been numerous complaints, that negative publicity, for example, numerous consumer complaints, may serve as well to elevate page rank on Google Search as favorable comments. The particular problem addressed in The New York Times article, which involved DecorMyEyes, was addressed shortly thereafter by an undisclosed fix in the Google algorithm. According to Google, it was not the frequently published consumer complaints about DecorMyEyes which resulted in the high ranking but mentions on news websites of events which affected the firm such as legal actions against it. Google Search Console helps to check for websites that use duplicate or copyright content.
In 2013, Google significantly upgraded its search algorithm with "Hummingbird". 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.
On certain occasions, the logo on Google's webpage will change to a special version, known as a "Google Doodle". This is a picture, drawing, animation or interactive game that includes the logo. It is usually done for a special event or day although not all of them are well known. Clicking on the Doodle links to a string of Google search results about the topic. The first was a reference to the Burning Man Festival in 1998, and others have been produced for the birthdays of notable people like Albert Einstein, historical events like the interlocking Lego block's 50th anniversary and holidays like Valentine's Day. Some Google Doodles have interactivity beyond a simple search, such as the famous "Google Pacman" version that appeared on May 21, 2010.
Google offers a "Google Search" mobile app for Android and iOS devices. The mobile apps exclusively feature a "feed", a news feed-style page of continually-updated developments on news and topics of interest to individual users. Android devices were introduced to a preview of the feed in December 2016, while it was made official on both Android and iOS in July 2017.
In April 2016, Google updated its Search app on Android to feature "Trends"; search queries gaining popularity appeared in the autocomplete box along with normal query autocompletion. The update received significant backlash, due to encouraging search queries unrelated to users' interests or intentions, prompting the company to issue an update with an opt-out option. In September 2017, the Google Search app on iOS was updated to feature the same functionality.
Until May 2013, Google Search had offered a feature to translate search queries into other languages. A Google spokesperson told Search Engine Land that "Removing features is always tough, but we do think very hard about each decision and its implications for our users. Unfortunately, this feature never saw much pick up".
Instant search was announced in September 2010 as a feature that displayed suggested results while the user typed in their search query. The primary advantage of the new system was its ability to save time, with Marissa Mayer, then-vice president of search products and user experience, proclaiming that the feature would save 2–5 seconds per search, elaborating that "That may not seem like a lot at first, but it adds up. With Google Instant, we estimate that we'll save our users 11 hours with each passing second!" Matt Van Wagner of Search Engine Land wrote that "Personally, I kind of like Google Instant and I think it represents a natural evolution in the way search works", and also praised Google's efforts in public relations, writing that "With just a press conference and a few well-placed interviews, Google has parlayed this relatively minor speed improvement into an attention-grabbing front-page news story". The upgrade also became notable for the company switching Google Search's underlying technology from HTML to AJAX.
Instant Search could be disabled via Google's "preferences" menu for those who didn't want its functionality.
There are a number of reasons you may not be seeing search queries for a particular topic. Among other things, we apply a narrow set of removal policies for pornography, violence, and hate speech. It's important to note that removing queries from Autocomplete is a hard problem, and not as simple as blacklisting particular terms and phrases.
In search, we get more than one billion searches each day. Because of this, we take an algorithmic approach to removals, and just like our search algorithms, these are imperfect. We will continue to work to improve our approach to removals in Autocomplete, and are listening carefully to feedback from our users.
Our algorithms look not only at specific words, but compound queries based on those words, and across all languages. So, for example, if there's a bad word in Russian, we may remove a compound word including the transliteration of the Russian word into English. We also look at the search results themselves for given queries. So, for example, if the results for a particular query seem pornographic, our algorithms may remove that query from Autocomplete, even if the query itself wouldn't otherwise violate our policies. This system is neither perfect nor instantaneous, and we will continue to work to make it better.
PC Magazine discussed the inconsistency in how some forms of the same topic are allowed; for instance, "lesbian" was blocked, while "gay" was not, and "cocaine" was blocked, while "crack" and "heroin" were not. The report further stated that seemingly normal words were also blocked due to pornographic innuendos, most notably "scat", likely due to having two completely separate contextual meanings, one for music and one for a sexual practice.
In July 2017, Google removed Instant results, due to a growing number of searches on mobile devices, where interaction with search, as well as screen sizes, differ significantly from a computer.
Various search engines provide encrypted Web search facilities. In May 2010 Google rolled out SSL-encrypted web search. The encrypted search can be accessed at
encrypted.google.com However, the web search is encrypted via Transport Layer Security (TLS) by default today, thus every search request should be automatically encrypted if TLS is supported by the web browser. On its support website, Google announced that the address
encrypted.google.com will be turned off in April 30 of 2018, stating that all Google products and most new browsers use HTTPS connections as the reason for the discontinuation.
Searches made by search engines, including Google, leave traces. This raises concerns about privacy. In principle, if details of a user's searches are found, those with access to the information—principally state agencies responsible for law enforcement and similar matters—can make deductions about the user's activities. This has been used for the detection and prosecution of lawbreakers; for example a murderer was found and convicted after searching for terms such as "tips with killing with a baseball bat".
A search may leave traces both on a computer used to make the search, and in records kept by the search provider. When using a search engine through a browser program on a computer, search terms and other information may be stored on the computer by default, unless the browser is set not to do this, or they are erased. Saved terms may be discovered on forensic analysis of the computer. An Internet Service Provider (ISP) or search engine provider (e.g., Google) may store records which relate search terms to an IP address and a time. Whether such logs are kept, and access to them by law enforcement agencies, is subject to legislation in different jurisdictions and working practices; the law may mandate, prohibit, or say nothing about logging of various types of information. Some search engines, located in jurisdictions where it is not illegal, make a feature of not storing user search information.
The keywords suggested by the Autocomplete feature show a population of users' research which is made possible by an identity management system. Volumes of personal data are collected via Eddystone web and proximity beacons.
Google has been criticized for placing long-term cookies on users' machines to store these preferences, a tactic which also enables them to track a user's search terms and retain the data for more than a year.
Since 2012, Google Inc. has globally introduced encrypted connections for most of its clients, in order to bypass governative blockings of the commercial and IT services.
In late June 2011, Google introduced a new look to the Google home page in order to boost the use of the Google+ social tools.
One of the major changes was replacing the classic navigation bar with a black one. Google's digital creative director Chris Wiggins explains: "We're working on a project to bring you a new and improved Google experience, and over the next few months, you'll continue to see more updates to our look and feel." The new navigation bar has been negatively received by a vocal minority.
In November 2013, Google started testing yellow labels for advertisements displayed in search results, to improve user experience. The new labels, highlighted in yellow color, and aligned to the left of each sponsored link help users clearly differentiate between organic and sponsored results.
On December 15, 2016, Google rolled out a new desktop search interface that mimics their modular mobile user interface. The mobile design consists of a tabular design that highlights search features in boxes. and works by imitating the desktop Knowledge Graph real estate, which appears in the right-hand rail of the search engine result page, these featured elements frequently feature Twitter carousels, People Also Search For, and Top Stories (vertical and horizontal design) modules. The Local Pack and Answer Box were two of the original features of the Google SERP that were primarily showcased in this manner, but this new layout creates a previously unseen level of design consistency for Google results.
In addition to its tool for searching webpages, Google also provides services for searching images, Usenet newsgroups, news websites, videos, searching by locality, maps, and items for sale online. In 2012, Google has indexed over 30 trillion web pages, and received 100 billion queries per month. It also caches much of the content that it indexes. Google operates other tools and services including Google News, Google Shopping, Google Maps, Google Custom Search, Google Earth, Google Docs, Picasa, Panoramio, YouTube, Google Translate, Google Blog Search and Google Desktop Search.
There are also products available from Google that are not directly search-related. Gmail, for example, is a webmail application, but still includes search features; Google Browser Sync does not offer any search facilities, although it aims to organize your browsing time.
Also Google starts many new beta products, like Google Social Search or Google Image Swirl.
In 2009, Google claimed that a search query requires altogether about 1 kJ or 0.0003 kW·h, which is enough to raise the temperature of one liter of water by 0.24 °C. According to green search engine Ecosia, the industry standard for search engines is estimated to be about 0.2 grams of CO2 emission per search. Google's 40,000 searches per second translate to 8 kg CO2 per second or over 252 million kilos of CO2 per year.
Google flags search results with the message "This site may harm your computer" if the site is known to install malicious software in the background or otherwise surreptitiously. Google does this to protect users against visiting sites that could harm their computers. For approximately 40 minutes on January 31, 2009, all search results were mistakenly classified as malware and could therefore not be clicked; instead a warning message was displayed and the user was required to enter the requested URL manually. The bug was caused by human error. The URL of "/" (which expands to all URLs) was mistakenly added to the malware patterns file.
In 2007, a group of researchers observed a tendency for users to rely on Google Search exclusively for finding information, writing that "With the Google interface the user gets the impression that the search results imply a kind of totality. ... In fact, one only sees a small part of what one could see if one also integrates other research tools."
In 2011, Google Search query results have been shown to be tailored to users by Internet activist Eli Pariser, effectively isolating users in what he defined as a filter bubble. Pariser holds algorithms used in search engines such as Google Search responsible for catering "a personal ecosystem of information". Although contrasting views have mitigated the potential threat of "informational dystopia" and questioned the scientific nature of Pariser's claims, filter bubbles have been mentioned to account for the surprising results of the U.S. presidential election in 2016 alongside fake news and echo chambers, suggesting that Facebook and Google have designed personalized online realities in which "we only see and hear what we like".
In 2012 the US Federal Trade Commission fined Google US$22.5 million for violating their agreement not to violate the privacy of users of the Apple's Safari web browser. The FTC was also continuing to investigate if Google's favoring of their own services in their search results violated antitrust regulations.
Since Dec. 4, 2009, Google has been personalized for everyone. So when I had two friends this spring Google "BP," one of them got a set of links that was about investment opportunities in BP. The other one got information about the oil spill ...
... The global village that was once the internet ... digital islands of isolation that are drifting further apart each day ... your experience online grows increasingly personalized ...
A Google Account is a user account that is required for access, authentication and authorization to certain online Google services.Google Custom Search
Google Custom Search (formerly known as Google Co-op) is a platform provided by Google that allows web developers to feature specialized information in web searches, refine and categorize queries and create customized search engines, based on Google Search. The service allows users to narrow the 11.5 billion indexed webpages down to a topical group of pages relevant to the creator's needs. Google launched the service on October 23, 2006.Google Dictionary
Google Dictionary is an online dictionary service of Google that can be accessed by using the "define" operator and other similar phrases in Google Search. It is also available in Google Translate and in the form of an extension for Google Chrome. The dictionary content is licensed from Oxford University Press's OxfordDictionaries.com. It is available in different languages such as English, Spanish and French. The service also contains pronunciation audio, Google Translate, word origin chart, Ngram Viewer, and word games among other features for the English language version. Originally available as a standalone service it was integrated into Google Search with the separate service being discontinued in August 2011.
Microsoft's Bing also provides a similar dictionary service which licences dictionary data from Oxford Dictionaries as well. Apple also licences dictionary data from Oxford for its iOS and macOS products.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 Images
Google Images is a search service owned by Google that allows users to search the Web for image content. It was introduced on July 12, 2001 due to a demand for pictures of Jennifer Lopez's green Versace dress that the regular Google search couldn't handle. In 2011, reverse image search functionality was added to it.
When searching for an image, a thumbnail of each matching image is displayed. When the user clicks on a thumbnail, the image is displayed in a larger size, and users may visit the page on which the image is used.Google Insights for Search
Google Insights for Search was a service by Google similar to Google Trends, providing insights into the search terms people use in the Google search engine. Unlike Google Trends, Google Insights for Search provides a visual representation of regional interest on a country's map. It displays top searches and rising searches that may help with keyword research. Results can be narrowed down with categories that are displayed for each search terms.
Term order is important in searches, and that different results will be found if keywords are placed in a different order.On September 27, 2012, Google Insights for Search was closed and merged into Google Trends again.Google News
Google News is a news aggregator and app developed by Google. It presents a continuous, customizable flow of articles organized from thousands of publishers and magazines. Google News is available on Android, iOS, and the web.
A beta version was launched in September 2002, and released officially in January 2006. The initial idea was developed by Krishna Bharat.Google Personalized Search
Google Personalized Search is a personalized search feature of Google Search, introduced in 2004. All searches on Google Search are associated with a browser cookie record. Then, when a user performs a search, the search results are not only based on the relevance of each web page to the search term, but also on which websites the user (or someone else using the same browser) visited through previous search results. This provides a more personalized experience that can increase the relevance of the search results for the particular user. Such filtering may also have side effects, such as creating a filter bubble.
Changes in Googles search algorithm in later years put less importance on user data, which means the impact of personalized search is limited on search results. Acting on criticism, Google has also made it possible to turn off the feature.Google Real-Time Search
Google Real-Time Search was a feature of Google Search provided by Google in which search results also sometimes included real-time information from sources such as Twitter, Facebook, blogs, and news websites. The feature was introduced on December 7, 2009 and went off-line on July 2, 2011 after the deal with Twitter expired. Real-Time Search included Facebook status updates beginning on February 24, 2010. A feature similar to Real-Time Search was already available on Microsoft's Bing search engine, which showed results from Twitter and Facebook.Google Search Console
Google Search Console (previously Google Webmaster Tools) is a no-charge web service by Google for webmasters. It allows webmasters to check indexing status and optimize visibility of their websites.
As of May 20, 2015, Google rebranded Google Webmaster Tools as Google Search Console. In January 2018, Google introduced a new version of the Search Console, with a refreshed user interface and improvements.Google Trends
Google Trends is a website by Google that analyzes the popularity of top search queries in Google Search across various regions and languages. The website uses graphs to compare the search volume of different queries over time.
On August 5, 2008, Google launched Google Insights for Search, a more sophisticated and advanced service displaying search trends data. On September 27, 2012, Google merged Google Insights for Search into Google Trends.Google Videos
Google Videos is a video search engine from Google, similar to Google Images. It allows searching the World Wide Web for video clips.
The service evolved from Google Video, Google's discontinued video hosting service that also allowed to search the web for video clips.Google Voice Search
Google Voice Search or Search by Voice is a Google product that allows users to use Google Search by speaking on a mobile phone or computer, i.e. have the device search for data upon entering information on what to search into the device by speaking.
Initially named as Voice Action which allowed one to give speech commands to an Android phone. Once only available for the U.S. English locale – commands were later recognizable and replied to in American, British, and Indian English; French, Italian, German, and Spanish.In Android 4.1+ (Jelly Bean), it was merged with Google Now.
In August 2014, a new feature was added to Google Voice Search, allowing users to choose up to five languages and the app will automatically understand the spoken language.Outline of Google
The following outline is provided as an overview of and topical guide to Google:
Google – American multinational technology company specializing in Internet-related services and products that include online advertising technologies, search, cloud computing, software, and hardware.PageRank
PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. PageRank was named after Larry Page, one of the founders of Google. PageRank is a way of measuring the importance of website pages. According to Google: PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites. Currently, PageRank is not the only algorithm used by Google to order search results, but it is the first algorithm that was used by the company, and it is the best known.SafeSearch
SafeSearch is a feature of Google Search that acts as an automated filter of pornography and potentially offensive content.
A 2003 report by Harvard Law School's Berkman Center for Internet & Society stated that SafeSearch excluded many innocuous websites from search-result listings, including ones created by the White House, IBM, the American Library Association and Liz Claiborne. On the other hand, many pornographic images slip through the filter, even when "innocent" search terms are entered. Blacklisting certain search terms is hindered by homographs (e.g., "beaver"), blacklisting certain URLs is rendered ineffective by the changing URLs of porn sites, and software to tag images with copious amounts of flesh tones as pornographic content is problematic because there are a variety of skin tones and pictures of babies tend to have a lot of flesh tones. Google's ability to filter porn has been an important factor in its relationship with the People's Republic of China.On 11 November 2009, Google introduced SafeSearch Lock, which allows users with Google accounts to lock on the "High" mode of SafeSearch in Google's Web, image and video searches. Once configured, the user can log out of their Google account and the setting will stick to prevent any change to the filtering level. Another approach uses what are known as Safe Search websites, such as WackySafe that have Google SafeSearch always enabled when a search is done. This provides a consistent platform that children can use where they will always be guaranteed that the results will be strict filtered. Only relying on Google.com to have SafeSearch locked can be a problem when a child is using a different computer, since the search settings may have changed and become potentially unsafe.
On 12 December 2012, Google removed the option to turn off the filter entirely, requiring users to enter more specific search queries to access adult content But this happens only to English sites and non-English users are still required to be careful with their local language search as Google is not filtering most of the adult contents even with safe search on and with specific keywords.Search engine optimization
Search engine optimization (SEO) is the process of affecting the online visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results. In general, the earlier (or higher ranked on the search results page), and more frequently a website appears in the search results list, the more visitors it will receive from the search engine's users; these visitors can then be converted into customers. SEO may target different kinds of search, including image search, video search, academic search, news search, and industry-specific vertical search engines. SEO differs from local search engine optimization in that the latter is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services. The former instead is more focused on national or international searches.
As an Internet marketing strategy, SEO considers how search engines work, the computer programmed algorithms which dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, adding content, doing HTML, and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic. By May 2015, mobile search had surpassed desktop search. In 2015, it was reported that Google is developing and promoting mobile search as a key feature within future products. In response, many brands are beginning to take a different approach to their Internet marketing strategies.Timeline of Google Search

A web search engine or Internet search engine is a software system that is designed to carry out web search (Internet search), which means to search the World Wide Web in a systematic way for particular information specified in a web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). The information may be a mix of web pages, images, videos, infographics, articles, research papers and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.
Internet content that is not capable of being searched by a web search engine is generally described as the deep web.
