98-459: In 2021, Microsoft Advertising surpassed US$ 10 billion in annual revenue. Microsoft was the last of the "big three" search engines (which also includes Google and Yahoo! ) to develop its own system for delivering pay-per-click (PPC) ads. Until the beginning of 2006, all of the ads displayed on the MSN Search engine were supplied by Overture (and later Yahoo!). MSN collected a portion of

196-523: A memex . He described the system in an article titled " As We May Think " that was published in The Atlantic Monthly . The memex was intended to give a user the capability to overcome the ever-increasing difficulty of locating information in ever-growing centralized indices of scientific work. Vannevar Bush envisioned libraries of research with connected annotations, which are similar to modern hyperlinks . Link analysis eventually became

294-441: A Google Ad. One of the study's authors, InfluenceMap stated "Google is letting groups with a vested interest in the continued use of fossil fuels pay to influence the resources people receive when they are trying to educate themselves. The oil and gas sector has moved away from contesting the science of climate change and now instead seeks to influence public discussions about decarbonization in its favor." A report conducted by

392-556: A Google Ads campaign therefore depends on a variety of factors, including the maximum amount an advertiser is willing to pay-per-click of the keyword, and the quality score of the ad (based on its relevance and click frequency and ad extensions). Although an advanced bidding strategy can be used to automatically reach a predefined Cost per action (CPA), this should not be confused with a fixed CPA pricing model. In addition to tracking clicks, Google Ads provides advertisers an ability to track and report other conversions that happen after

490-760: A breach of EU trademark law, but that the content of some advertisements that are linked by Google keywords may well be in breach depending upon the particular facts of the case." Additionally, in some American jurisdictions, the use of a person's name as a keyword for advertising or trade purposes without the person's consent has raised Right to Privacy concerns. In 2013, the Tenth Circuit Court of Appeals held in 1-800 Contacts, Inc. v. Lens.com, Inc. that online contact lens seller Lens.com did not commit trademark infringement when it purchased AdWords and other search advertisements using competitor 1-800 Contacts ' federally registered 1800 CONTACTS trademark as

588-498: A campaign management service known as "Jumpstart". In 2007, Google acquired DoubleClick for $ 3.1 billion. The acquisition was strategically important for Google, providing access to DoubleClick's advanced ad-serving technology and established industry relationships. This deal, while "transforming Google into a powerhouse", later attracted antitrust scrutiny, raising questions about its impact on market competition and digital advertising dominance. In January of 2007 Google purchased

686-623: A certain number of pages crawled, amount of data indexed, or time spent on the website, the spider stops crawling and moves on. "[N]o web crawler may actually crawl the entire reachable web. Due to infinite websites, spider traps, spam, and other exigencies of the real web, crawlers instead apply a crawl policy to determine when the crawling of a site should be deemed sufficient. Some websites are crawled exhaustively, while others are crawled only partially". Indexing means associating words and other definable tokens found on web pages to their domain names and HTML -based fields. The associations are made in

784-454: A critical area for scrutiny. The AdWords system was initially implemented on top of the MySQL database engine. After the system had been launched, management decided to use Oracle instead but was eventually reverted to MySQL after the system became much slower. Eventually, Google developed a custom distributed Relational database (RD) known as Google Spanner specifically for the needs of

882-591: A crucial component of search engines through algorithms such as Hyper Search and PageRank . The first internet search engines predate the debut of the Web in December 1990: WHOIS user search dates back to 1982, and the Knowbot Information Service multi-network user search was first implemented in 1989. The first well documented search engine that searched content files, namely FTP files,

980-405: A desktop tool to manage campaigns offline, called Microsoft Ads Editor. Using this editor you can make offline changes to your campaigns and later sync it online. Microsoft Advertising also provides APIs that can be used to manage advertising campaigns. Search engine A search engine is a software system that provides hyperlinks to web pages and other relevant information on

1078-837: A disagreement with the government over censorship and a cyberattack. But Bing is in top three web search engine with a market share of 14.95%. Baidu is on top with 49.1% market share. Most countries' markets in the European Union are dominated by Google, except for the Czech Republic , where Seznam is a strong competitor. The search engine Qwant is based in Paris , France , where it attracts most of its 50 million monthly registered users from. Although search engines are programmed to rank websites based on some combination of their popularity and relevancy, empirical studies indicate various political, economic, and social biases in

1176-482: A keyword search of most Gopher menu titles in the entire Gopher listings. Jughead (Jonzy's Universal Gopher Hierarchy Excavation And Display) was a tool for obtaining menu information from specific Gopher servers. While the name of the search engine " Archie Search Engine " was not a reference to the Archie comic book series, " Veronica " and " Jughead " are characters in the series, thus referencing their predecessor. In

1274-592: A keyword. In August 2016, the Federal Trade Commission filed an administrative complaint against 1-800 Contacts alleging that its search advertising trademark enforcement practices have unreasonably restrained competition in violation of the FTC Act. 1-800 Contacts has denied all wrongdoing and is scheduled to appear before an FTC administrative law judge in April 2017. In 2018, Google implemented

1372-566: A minimalist interface to its search engine. In contrast, many of its competitors embedded a search engine in a web portal . In fact, the Google search engine became so popular that spoof engines emerged such as Mystery Seeker . By 2000, Yahoo! was providing search services based on Inktomi's search engine. Yahoo! acquired Inktomi in 2002, and Overture (which owned AlltheWeb and AltaVista) in 2003. Yahoo! switched to Google's search engine until 2004, when it launched its own search engine based on

1470-406: A page can be useful to the website when the actual page has been lost, but this problem is also considered a mild form of linkrot . Typically when a user enters a query into a search engine it is a few keywords . The index already has the names of the sites containing the keywords, and these are instantly obtained from the index. The real processing load is in generating the web pages that are

1568-453: A policy change that restricts the advertising of consumer technical support, including services related to troubleshooting, security, virus removal, internet connectivity, online accounts (such as password resets or login support), or software installation", Google's Director of Global Product Policy, David Graff stated that the policy was intended to "address abuse" and "fraudulent activity" from third-party technical support providers, and that

1666-408: A public database, made available for web search queries. A query from a user can be a single word, multiple words or a sentence. The index helps find information relating to the query as quickly as possible. Some of the techniques for indexing, and caching are trade secrets, whereas web crawling is a straightforward process of visiting all sites on a systematic basis. Between visits by the spider ,

1764-475: A search engine to discover it, and to have a web site's record updated after a substantial redesign. Some search engine submission software not only submits websites to multiple search engines, but also adds links to websites from their own pages. This could appear helpful in increasing a website's ranking , because external links are one of the most important factors determining a website's ranking. However, John Mueller of Google has stated that this "can lead to

1862-464: A search function was added, allowing users to search Yahoo! Directory. It became one of the most popular ways for people to find web pages of interest, but its search function operated on its web directory, rather than its full-text copies of web pages. Soon after, a number of search engines appeared and vied for popularity. These included Magellan , Excite , Infoseek , Inktomi , Northern Light , and AltaVista . Information seekers could also browse

1960-624: A searchable database of file names; however, Archie Search Engine did not index the contents of these sites since the amount of data was so limited it could be readily searched manually. The rise of Gopher (created in 1991 by Mark McCahill at the University of Minnesota ) led to two new search programs, Veronica and Jughead . Like Archie, they searched the file names and titles stored in Gopher index systems. Veronica (Very Easy Rodent-Oriented Net-wide Index to Computerized Archives) provided

2058-476: A tool that enables advertisers to maintain compliance with privacy laws while minimizing disruption to targeted advertising, its effectiveness and genuineness in protecting user privacy have been subjects of debate. Critics argue that while the tool ostensibly supports compliance, it also allows Google to maintain its dominant position in the digital advertising market by providing a mechanism that superficially addresses privacy concerns without significantly altering

2156-402: A tremendous number of unnatural links for your site" with a negative impact on site ranking. In comparison to search engines, a social bookmarking system has several advantages over traditional automated resource location and classification software, such as search engine spiders . All tag-based classification of Internet resources (such as web sites) is done by human beings, who understand

2254-561: A verification program for legitimate providers would be rolled out "in the coming months". This is yet to manifest, resulting in an effective ban on all IT support and repair related services on the Google Ads platform. Commentators have expressed concerns that this is an attempt by Google to stifle consumers' right to repair electronic devices. Fossil fuel companies, funders and public relations agencies including ExxonMobil , Shell , Aramco , McKinsey , and Goldman Sachs are among

2352-507: Is a nonprofit campaign for sex worker rights and is not advertising or selling adult sexual services. After TOBL members held a protest outside Google's European headquarters in Dublin and sent in written complaints, Google reviewed the group's website. Google found the website content to be advocating a political position and restored the AdWords advertisement. In June 2012, Google rejected

2450-482: Is a system that generates an " inverted index " by analyzing texts it locates. This first form relies much more heavily on the computer itself to do the bulk of the work. Most Web search engines are commercial ventures supported by advertising revenue and thus some of them allow advertisers to have their listings ranked higher in search results for a fee. Search engines that do not accept money for their search results make money by running search related ads alongside

2548-588: Is by far the world's most used search engine, with a market share of 90.6%, and the world's other most used search engines were Bing , Yahoo! , Baidu , Yandex , and DuckDuckGo . In 2024, Google's dominance was ruled an illegal monopoly in a case brought by the US Department of Justice. In Russia, Yandex has a market share of 62.6%, compared to Google's 28.3%. And Yandex is the second most used search engine on smartphones in Asia and Europe. In China, Baidu

2646-475: Is illegal. Biases can also be a result of social processes, as search engine algorithms are frequently designed to exclude non-normative viewpoints in favor of more "popular" results. Indexing algorithms of major search engines skew towards coverage of U.S.-based sites, rather than websites from non-U.S. countries. Google Bombing is one example of an attempt to manipulate search results for political, social or commercial reasons. Several scholars have studied

2744-536: Is little evidence for the filter bubble. On the contrary, a number of studies trying to verify the existence of filter bubbles have found only minor levels of personalisation in search, that most people encounter a range of views when browsing online, and that Google news tends to promote mainstream established news outlets. The global growth of the Internet and electronic media in the Arab and Muslim world during

2842-445: Is set by a Google reviewer and indicates what "audiences the ad and website are appropriate for." This will change at what time, on which page, and in which country an ad can appear. As of December 2010, Google AdWords decreased restrictions on sales of hard alcohol. It now allows ads that promote the sale of hard alcohol and liquor. This is an extension of a policy change that was made in December 2008, which permitted ads that promote

2940-709: Is that search engines and social media platforms use algorithms to selectively guess what information a user would like to see, based on information about the user (such as location, past click behaviour and search history). As a result, websites tend to show only information that agrees with the user's past viewpoint. According to Eli Pariser users get less exposure to conflicting viewpoints and are isolated intellectually in their own informational bubble. Since this problem has been identified, competing search engines have emerged that seek to avoid this problem by not tracking or "bubbling" users, such as DuckDuckGo . However many scholars have questioned Pariser's view, finding that there

3038-538: Is the most popular search engine. South Korea's homegrown search portal, Naver , is used for 62.8% of online searches in the country. Yahoo! Japan and Yahoo! Taiwan are the most popular avenues for Internet searches in Japan and Taiwan, respectively. China is one of few countries where Google is not in the top three web search engines for market share. Google was previously a top search engine in China, but withdrew after

3136-594: The Australian Sex Party 's ads for AdWords and sponsored search results for the July 12 by-election for the state seat of Melbourne , saying the Australian Sex Party breached its rules which prevent solicitation of donations by a website that did not display tax exempt status. Although the Australian Sex Party amended its website to display tax deductibility information, Google continued to ban

3234-620: The Baidu search engine, which was founded by him in China and launched in 2000. In 1996, Netscape was looking to give a single search engine an exclusive deal as the featured search engine on Netscape's web browser. There was so much interest that instead, Netscape struck deals with five of the major search engines: for $ 5 million a year, each search engine would be in rotation on the Netscape search engine page. The five engines were Yahoo!, Magellan, Lycos, Infoseek, and Excite. Google adopted

3332-659: The Foreign Corrupt Practices Act . In December 2019, France fined Google €150 million for advertiser suspensions on Google Ads, arguing it had "abused its dominant position by adopting opaque and difficult to understand rules" which it was then free to "interpret and modify" at its own discretion. In early 2022, Google suspended all ad sales in Russia in response to the ongoing invasion of Ukraine. Over 1,000 Russian businesses that had purchased pre-paid ads, which were neither delivered nor refunded, joined

3430-534: The Google Play app store, and AdSense website publisher partners. Google Ads' system is based partly on cookies and partly on keywords determined by advertisers. Google uses these characteristics to place advertising copy on pages that they think might be relevant. In 2023, Google introduced Topics API , which allows targeting ads based on browsing history stored in browser, to Google Chrome . Advertisers pay when users divert their browsing to click on

3528-411: The cached version of the page (some or all the content needed to render it) stored in the search engine working memory is quickly sent to an inquirer. If a visit is overdue, the search engine can just act as a web proxy instead. In this case, the page may differ from the search terms indexed. The cached page holds the appearance of the version whose words were previously indexed, so a cached version of

3626-603: The AdWords service. The suit was settled in 2004 after Yahoo! acquired Overture; Google agreed to issue 2.7 million shares of common stock to Yahoo! in exchange for a perpetual license under the patent. In 2006, Google settled a click fraud lawsuit for US$ 90 million. In May 2011, Google cancelled the AdWords advertisement purchased by a Dublin sex worker rights group named "Turn Off the Blue Light" (TOBL), claiming that it represented an "egregious violation" of company ad policy by "selling adult sexual services". However, TOBL

3724-647: The Adwords account. This allows advertisers to target their ads to drive conversions more effectively. For most traffic, Google sends a unique identifier for each click (in a gclid parameter), allowing to determine source of conversion precisely. To comply with tracking restrictions on Apple devices, anonymized identifiers that aren't associated with specific person are used (called wbraid and gbraid ). Google Ads provides ability to report many of such anonymous conversions by using "modeled conversions" that combine additional customer details to deduce, which user to attribute

3822-405: The Internet without assistance. They can either submit one web page at a time, or they can submit the entire site using a sitemap , but it is normally only necessary to submit the home page of a web site as search engines are able to crawl a well designed website. There are two remaining reasons to submit a web site or web page to a search engine: to add an entirely new web site without waiting for

3920-506: The Jewish version of Google, and Christian search engine SeekFind.org. SeekFind filters sites that attack or degrade their faith. Web search engine submission is a process in which a webmaster submits a website directly to a search engine. While search engine submission is sometimes presented as a way to promote a website, it generally is not necessary because the major search engines use web crawlers that will eventually find most web sites on

4018-548: The MSN division of Microsoft. In June 2006, the contract between Yahoo! and Microsoft had expired and Microsoft was displaying only ads from adCenter until 2010. In November 2006 Microsoft acquired Deep Metrix, a company situated in Gatineau, Canada, that created web-analytics software. Microsoft has built a new product adCenter Analytics based on the acquired technology. In October, 2007 the beta version of Microsoft Project Gatineau

4116-661: The Microsoft Search Alliance. A complete transition of all Yahoo! sponsored ad clients to Microsoft adCenter occurred in October 2010. On September 10, 2012, adCenter was renamed to Bing Ads , and the Search Alliance was renamed the Yahoo! Bing Network. In April 2015, the Yahoo! partnership was modified; Yahoo! Search will only have to feature Bing results on the "majority" of desktop traffic, leaving

4214-551: The Publisher Leadership Council was created under the umbrella of Microsoft Advertising. The council was responsible for delivering the next-generation advertising platform for the publishers of digital media resulting in the formation of Microsoft pubCenter . In January 2010, Microsoft announced a deal in which it would take over the functional operation of Yahoo! Search, and set up a joint venture to sell advertising on both Yahoo! Search and Bing known as

4312-630: The Tech Transparency Project found that women from low-income areas in US cities are more likely to be targeted by anti-abortion crisis pregnancy centers than women in wealthier areas of the city. Many of these crisis centers have portrayed themselves as abortion clinics while advocating anti-abortion measures for pregnant women. The research was conducted in Atlanta, Miami, and Phoenix with women from three different income brackets, using

4410-454: The Unix world standard of assigning programs and files short, cryptic names such as grep, cat, troff, sed, awk, perl, and so on. AdWords Editor Google Ads formerly known as Google Adwords is an online advertising platform developed by Google , where advertisers bid to display brief advertisements, service offerings, product listings, and videos to web users. It can place ads in

4508-457: The Web in response to a user's query . The user inputs a query within a web browser or a mobile app , and the search results are often a list of hyperlinks, accompanied by textual summaries and images. Users also have the option of limiting the search to a specific type of results, such as images, videos, or news. For a search provider, its engine is part of a distributed computing system that can encompass many data centers throughout

4606-440: The ad business. The interface offers Spreadsheet Editing, Search Query Reports, and conversion metrics. Google Ads have been the subject of lawsuits relating to Trademark Law ( Google, Inc. v. American Blind & Wallpaper Factory, Inc. and Rescuecom Corp. v. Google Inc. ), fraud ( Goddard v. Google, Inc. ), and click fraud . Overture Services, Inc. sued Google for patent infringement in April 2002 in relation to

4704-415: The ad revenue in return for displaying Yahoo!'s ads on its search engine. As search marketing grew, Microsoft began developing its own system, MSN adCenter, for selling PPC advertisements directly to advertisers. As the system was phased in, MSN Search (now Bing ) showed Yahoo! and adCenter advertising in its search results. Microsoft effort to create AdCenter was led by Tarek Najm, then general manager of

4802-612: The ads. The ads were reinstated on election eve after it was reported in the media that the Australian Sex Party was considering suing Google. On September 13, 2012, the Australian Sex Party lodged formal complaints against Google with the US Department of Justice and the Australian competition watchdog, accusing Google of "unlawful interference in the conduct of a state election in Victoria with corrupt intent" in violation of

4900-513: The advertising copy. Adverts can be implemented locally, nationally, or internationally. Google's text advertisements mimic what the average search result looks like on Google. Offering text-only search ads initially, Google unveiled "Showcase Shopping" ads in 2016 . With this format, retailers can choose to have a series of product images that appear in search results related to various search queries and keywords. In May 2016, Google announced Expanded Text Ads, allowing 23% more text. Image ads in

4998-639: The bankruptcy proceedings of the Russian Google subsidiary. Google has come under fire for allowing AdWords advertisers to bid on trademarked keywords. In 2004, Google started allowing advertisers to bid on a wide variety of search terms in the US and Canada, including trademarks of their competitors and in May 2008 expanded this policy to the UK and Ireland. Until 2023, advertisers were restricted from using other companies' trademarks in their advertisement text if

5096-470: The beginning of the Coronavirus crisis, Google blocked all face masks keywords from being eligible for ad targeting as part of a policy to prevent companies from attempting to capitalize on the pandemic. Every time a user conducts a search on Google, Google Ads runs an auction in real time to determine which search ads are displayed on the search results page as well as the ad's position. The cost of

5194-748: The branding of hard alcohol and liquor. From June 2007, Google banned AdWords adverts for student essay-writing services, a move which received positive feedback from universities. Google has a variety of specific keywords and categories that it prohibits that vary by type and country. For example, use of keywords for alcohol related products are prohibited in Thailand and Turkey; keywords for gambling and casinos are prohibited in Poland; keywords for abortion services are prohibited in Russia and Ukraine; and keywords for adult related services or products are prohibited worldwide as of June 2014. In March 2020, at

5292-401: The click such as purchases, sign ups or calls. Conversion tracking is implemented by sending an identifier to the advertiser's website as a URL parameter , which is then used by advertiser to send conversions to Google Ads, allowing Google Ads to trace conversion back to the original click for reporting. Google also allows advertisers to install a pixel on their website that sends conversions to

5390-504: The collections from Google and Bing (and others). While lack of investment and slow pace in technologies in the Muslim world has hindered progress and thwarted success of an Islamic search engine, targeting as the main consumers Islamic adherents, projects like Muxlim (a Muslim lifestyle site) received millions of dollars from investors like Rite Internet Ventures, and it also faltered. Other religion-oriented search engines are Jewogle,

5488-487: The combined technologies of its acquisitions. Microsoft first launched MSN Search in the fall of 1998 using search results from Inktomi. In early 1999, the site began to display listings from Looksmart , blended with results from Inktomi. For a short time in 1999, MSN Search used results from AltaVista instead. In 2004, Microsoft began a transition to its own search technology, powered by its own web crawler (called msnbot ). Microsoft's rebranded search engine, Bing ,

5586-419: The company open to "enhance the search experience" non-exclusively on both desktop and mobile. Additionally, Microsoft will take over as the exclusive seller of ads delivered through Bing; Yahoo! will sell its own ads through its new in-house Gemini platform. On June 29, 2015, AOL Inc. announced a deal and partnership to take over the majority of Microsoft's ad sales business. Under the pact, AOL will take over

5684-513: The complex intersection of aggressive digital advertising strategies and the stringent global data privacy standards that regulate them. This feature, which allows advertisers on the Google Ads platform to adjust how cookies are utilized based on user consent, is a response to heightened privacy expectations and legal frameworks such as the European Union's General Data Protection Regulation (GDPR) . While Google presents Consent Mode as

5782-454: The content of the resource, as opposed to software, which algorithmically attempts to determine the meaning and quality of a resource. Also, people can find and bookmark web pages that have not yet been noticed or indexed by web spiders. Additionally, a social bookmarking system can rank a resource based on how many times it has been bookmarked by users, which may be a more useful metric for end-users than systems that rank resources based on

5880-662: The conversion to. Google Ads can be integrated with Google Analytics 4 (GA4) , which can improve conversion tracking effectiveness. This integration allows for a more comprehensive understanding of user interactions across different platforms and devices. Google Ads introduced enhanced conversions to make conversion measurement more accurate. In 2018, Bloomberg News reported that Google had paid millions of dollars to Mastercard for its users' credit card data for offline conversion tracking purposes. The deal had not been publicly announced. The introduction of Google Consent Mode in 2020 represents an effort by Google to navigate

5978-512: The cultural changes triggered by search engines, and the representation of certain controversial topics in their results, such as terrorism in Ireland , climate change denial , and conspiracy theories . There has been concern raised that search engines such as Google and Bing provide customized results based on the user's activity history, leading to what has been termed echo chambers or filter bubbles by Eli Pariser in 2011. The argument

6076-560: The desired date range. It is also possible to weight by date because each page has a modification time. Most search engines support the use of the Boolean operators AND, OR and NOT to help end users refine the search query . Boolean operators are for literal searches that allow the user to refine and extend the terms of the search. The engine looks for the words or phrases exactly as entered. Some search engines provide an advanced feature called proximity search , which allows users to define

6174-629: The directory instead of doing a keyword-based search. In 1996, Robin Li developed the RankDex site-scoring algorithm for search engines results page ranking and received a US patent for the technology. It was the first search engine that used hyperlinks to measure the quality of websites it was indexing, predating the very similar algorithm patent filed by Google two years later in 1998. Larry Page referenced Li's work in some of his U.S. patents for PageRank. Li later used his Rankdex technology for

6272-801: The display network can be one of the several different standardized sizes as designated by the Interactive Advertising Bureau (IAB). Besides the Google search engine, advertisers also have the option of enabling their ads to show on Google's partner network, members of which receive a portion of the generated income. In 2024, Google Ads introduced AI-powered tools, including the "Ads Power Pair" of Search and Performance Max, designed to improve campaign efficiency across Google channels. These tools leverage first-party data, machine learning, and automated asset creation to enhance bidding, targeting, and audience reach. The "Family status" of an ad ("family safe," "non-family safe," or "adult")

6370-480: The distance between keywords. There is also concept-based searching where the research involves using statistical analysis on pages containing the words or phrases you search for. The usefulness of a search engine depends on the relevance of the result set it gives back. While there may be millions of web pages that include a particular word or phrase, some pages may be more relevant, popular, or authoritative than others. Most search engines employ methods to rank

6468-419: The dominant one in the 2000s and has remained so. It currently has a 91% global market share. The business of websites improving their visibility in search results , known as marketing and optimization , has thus largely focused on Google. In 1945, Vannevar Bush described an information retrieval system that would allow a user to access a great expanse of information, all at a single desk. He called it

6566-438: The existence at each site of an index file in a particular format. JumpStation (created in December 1993 by Jonathon Fletcher ) used a web robot to find web pages and to build its index, and used a web form as the interface to its query program. It was thus the first WWW resource-discovery tool to combine the three essential features of a web search engine (crawling, indexing, and searching) as described below. Because of

6664-402: The idea of selling search terms in 1998 from a small search engine company named goto.com . This move had a significant effect on the search engine business, which went from struggling to one of the most profitable businesses in the Internet. Search engines were also known as some of the brightest stars in the Internet investing frenzy that occurred in the late 1990s. Several companies entered

6762-528: The information they provide and the underlying assumptions about the technology. These biases can be a direct result of economic and commercial processes (e.g., companies that advertise with a search engine can become also more popular in its organic search results), and political processes (e.g., the removal of search results to comply with local laws). For example, Google will not surface certain neo-Nazi websites in France and Germany, where Holocaust denial

6860-402: The largest customers of Google Ads. One in five Google Ads for climate-related terms (e.g. net zero, carbon storage, carbon capture and energy transition) were paid by fossil fuel companies. A study by The Guardian and InfluenceMap found that Shell's ads appeared on 86% of searches for "net zero". Over half of users in a 2020 survey could not tell the difference between a normal Google result and

6958-618: The last decade has encouraged Islamic adherents in the Middle East and Asian sub-continent , to attempt their own search engines, their own filtered search portals that would enable users to perform safe searches . More than usual safe search filters, these Islamic web portals categorizing websites into being either " halal " or " haram ", based on interpretation of Sharia law . ImHalal came online in September 2011. Halalgoogling came online in July 2013. These use haram filters on

7056-435: The limited resources available on the platform it ran on, its indexing and hence searching were limited to the titles and headings found in the web pages the crawler encountered. One of the first "all text" crawler-based search engines was WebCrawler , which came out in 1994. Unlike its predecessors, it allowed users to search for any word in any web page , which has become the standard for all major search engines since. It

7154-541: The market spectacularly, receiving record gains during their initial public offerings . Some have taken down their public search engine and are marketing enterprise-only editions, such as Northern Light. Many search engine companies were caught up in the dot-com bubble , a speculation-driven market boom that peaked in March 2000. Around 2000, Google's search engine rose to prominence.

Beyond simple keyword lookups, search engines offer their own GUI - or command-driven operators and search parameters to refine
