Search Engines

from Wikipedia   Bing

Bing is a web search engine owned and operated by Microsoft. The service has its origins in Microsoft's previous search engines: MSN Search, Windows Live Search and later Live Search. Bing provides a variety of search services, including web, video, image and map search products. It is developed using ASP.NET.



Bing, Microsoft's replacement for Live Search, was unveiled by Microsoft CEO Steve Ballmer on May 28, 2009, at the All Things Digital conference in San Diego, California, for release on June 1, 2009. Notable new features at the time included the listing of search suggestions while queries are entered and a list of related searches (called "Explore pane") based on semantic technology from Powerset, which Microsoft had acquired in 2008.

In July 2009, Microsoft and Yahoo! announced a deal in which Bing would power Yahoo! Search. All Yahoo! Search global customers and partners made the transition by early 2012. The deal was altered in 2015, meaning Yahoo! was only required to use Bing for a "majority" of searches.

In December 2011, Microsoft stated that they were working on new back-end search infrastructure with the goal of delivering faster and slightly more relevant search results for users. Known as "Tiger", the new index-serving technology had been incorporated into Bing globally since August that year. In May 2012, Microsoft announced another redesign of its search engine that includes "Sidebar", a social feature that searches users' social networks for information relevant to the search query.

As of November 2015, Bing is the second largest search engine in the US, with a query volume of 20.9%, behind Google on 63.9%. Yahoo! Search, which Bing largely powers, has 12.5%.

from Wikipedia   DMOZ
is the most widely distributed data base of Web content classified by humans.

DMOZ (from directory.mozilla.org, an earlier domain name) was a multilingual open-content directory of World Wide Web links. The site and community who maintained it were also known as the Open Directory Project (ODP). It was owned by AOL (now a part of Verizon's Oath Inc.) but constructed and maintained by a community of volunteer editors.



DMOZ used a hierarchical ontology scheme for organizing site listings. Listings on a similar topic were grouped into categories which then included smaller categories.

DMOZ closed on March 17, 2017 because AOL no longer wished to support the project. The website became a single landing page on that day, with links to a static archive of DMOZ, and to the DMOZ discussion forum, where plans to rebrand and relaunch the directory are being discussed.

As of September 2017, a non-editable mirror remained available at dmoztools.net, and it was stated that while the DMOZ URL would not return, a successor version of the directory would, at Curlie.org. Although a website is now live at that domain, the top-level directory category page is currently just a static HTML file whose category links direct the user to the dmoztools.net static archive.

from Wikipedia   Google Search Console

Google Search, commonly referred to as Google Web Search or simply Google, is a web search engine developed by Google. It is the most-used search engine on the World Wide Web, handling more than three billion searches each day. As of February 2016, it is the most used search engine in the US with 64.0% market share.



The order of search on Google's search-results pages is based, in part, on a priority rank called a "PageRank". Google Search provides many different options for customized search, using Boolean operators such as exclusion ("-xx"), alternatives ("xx OR yy OR zz"), and wildcards ("Winston * Churchill" returns "Winston Churchill", "Winston Spencer Churchill", etc.). The same and other options can be specified in a different way on an Advanced Search page.

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. Google Search provides several features beyond searching for words. These include synonyms, weather forecasts, time zones, stock quotes, maps, earthquake data, movie showtimes, airports, home listings, and sports scores. There are special features for numbers, dates, and some specific forms, including ranges, prices, temperatures, money and measurement unit conversions, calculations, package tracking, patents, area codes, and language translation. 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 these deep neural networks.

In December 2016, Gary Illyes, a webmaster trends analyst with Google, announced that the search engine will be making a new, primary web index dedicated for mobile, with a secondary, less up-to-date index for desktop use. The change is a response from the continued growth in mobile, and a push for web developers to adopt a mobile-friendly version of their websites. Illyes stated the change will happen in "months".

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; one such search engine is Ixquick.

Major Search Engines and Directories

Search Engine Watch (SEW) is a website that provides news and information about search engines and search engine marketing.



Search Engine Watch was started by Danny Sullivan in 1996. In 1997, Sullivan sold it for an undisclosed amount to MecklerMedia (now WebMediaBrands). In 2005 the website and related Search Engine Strategies conference series were sold to Incisive Media for $43 million. On November 30, 2006 Danny Sullivan left Search Engine Watch, after his resignation announcement on August 29, 2006. Rebecca Lieb was named editor-in-chief the following month.

In 2015, Incisive Media sold SES, Search Engine Watch, and ClickZ to Blenheim Chalcot.

Google's Matt Cutts has called Search Engine Watch "a must read." Yahoo's Tim Mayer has said that it is the "most authoritative source on search."

from Wikipedia   Netscape Search

Netscape Communications (formerly known as Netscape Communications Corporation or Netscape) is an American computer services company known for its web browser, Netscape Navigator.

When Netscape was an independent company, its headquarters were in Mountain View, California.

Netscape's web browser was once dominant but it has lost most of that glare to its competitors Internet Explorer during the so-called first browser war. The usage share of Netscape had fallen from over ninety percent in the mid-1990s to less than one percent by the end of 2006.



Netscape is credited with creating JavaScript language, the most widely used language for client-side scripting of web pages. The company is also known for developing the SSL which is used for securing online communications that was used before its successor TLS took over.

Netscape stock traded from 1995 until 1999 when it was acquired by AOL in a pooling-of-interests transaction ultimately worth US $10 billion. Shortly before its acquisition by AOL, Netscape released the source code for its browser and created the Mozilla Organization to coordinate future development of its product. The Mozilla Organization rewrote the entire browser's source code based on the Gecko rendering engine; all future Netscape releases were based on this rewritten code. The Gecko engine would later be used to power the Mozilla Foundation's Firefox browser.

Under AOL, Netscape's browser development continued until December 2007 when AOL announced that the company would stop supporting the Netscape browser as of early 2008. As of 2011, AOL has continued to use the Netscape brand to market a discount Internet service provider.

Early years



Netscape was the first company to attempt to capitalize on the nascent World Wide Web. It was founded under the name Mosaic Communications Corporation on April 4, 1994, the brainchild of Jim Clark who had recruited Marc Andreessen as co-founder and Kleiner Perkins Caufield & Byers as investors. The first meeting between Clark and Andreessen was never truly about a software or service like Netscape, but more about a product that was similar to Nintendo. Clark recruited other early team members from SGI and NCSA Mosaic. Jim Barksdale came on board as CEO in January 1995. Jim Clark and Marc Andreessen originally created a 20-page concept pitch for an online gaming network to Nintendo for the Nintendo 64 console, but a deal was never reached. Marc Andreessen explains, "If they had shipped a year earlier, we probably would have done that instead of Netscape."

The company's first product was the web browser, called Mosaic Netscape 0.9, released on October 13, 1994. Within four months of its release, it had already taken three-quarters of the browser market. It became the main browser for Internet users in such a short time due to its superiority over other competition, like Mosaic. This browser was subsequently renamed Netscape Navigator, and the company took the 'Netscape' name (coined by employee Greg Sands, although it was also a trademark of Cisco Systems) on November 14, 1994 to avoid trademark ownership problems with NCSA, where the initial Netscape employees had previously created the NCSA Mosaic web browser. The Mosaic Netscape web browser did not use any NCSA Mosaic code. The internal codename for the company's browser was Mozilla, which stood for "Mosaic killer", as the company's goal was to displace NCSA Mosaic as the world's number one web browser. A cartoon Godzilla-like lizard mascot was drawn by artist-employee Dave Titus, which went well with the theme of crushing the competition. The Mozilla mascot featured prominently on Netscape's web site in the company's early years. However, the need to project a more "professional" image (especially towards corporate clients) led to this being removed.



On August 9, 1995, Netscape made an extremely successful IPO. The stock was set to be offered at US$14 per share, but a last-minute decision doubled the initial offering to US$28 per share. The stock's value soared to US$75 during the first day of trading, nearly a record for first-day gain. The stock closed at US$58.25, which gave Netscape a market value of US$2.9 billion. While it was unusual for a company to go public prior to becoming profitable, Netscape's revenues had, in fact, doubled every quarter in 1995. The success of this IPO subsequently inspired the use of the term "Netscape moment" to describe a high-visibility IPO that signals the dawn of a new industry. During this period, Netscape also pursued a publicity strategy (crafted by Rosanne Siino, then head of public relations) packaging Andreessen as the company's "rock star." The events of this period ultimately landed Andreessen, barefoot, on the cover of Time magazine.

Netscape advertised that "the web is for everyone" and stated one of its goals was to "level the playing field" among operating systems by providing a consistent web browsing experience across them. The Netscape web browser interface was identical on any computer. Netscape later experimented with prototypes of a web-based system which would enable users to access and edit their files anywhere across a network, no matter what computer or operating system they happened to be using. This did not escape the attention of Microsoft, which viewed the commoditization of operating systems as a direct threat to its bottom line, i.e. a move from Windows to another operating system would yield a similar browsing experience thus reducing barriers to change. It is alleged that several Microsoft executives visited the Netscape campus in June 1995 to propose dividing the market (an allegation denied by Microsoft and, if true, would have breached antitrust laws), which would have allowed Microsoft to produce web browser software for Windows while leaving all other operating systems to Netscape. Netscape refused the proposition.



Microsoft released version 1.0 of Internet Explorer as a part of the Windows 95 Plus Pack add-on. According to former Spyglass developer Eric Sink, Internet Explorer was based not on NCSA Mosaic as commonly believed, but on a version of Mosaic developed at Spyglass (which itself was based upon NCSA Mosaic). Microsoft quickly released several successive versions of Internet Explorer, bundling them with Windows, never charging for them, financing their development and marketing with revenues from other areas of the company. This period of time became known as the browser wars, in which Netscape Communicator and Internet Explorer added many new features and went through many version numbers (not always in a logical fashion) in attempts to outdo each other. But Internet Explorer had the upper hand, as the amount of manpower and capital dedicated to it eventually surpassed the resources available in Netscape's entire business. By version 3.0, IE was roughly a feature-for-feature equivalent of Netscape Communicator, and by version 4.0, it was generally considered to be more stable on Windows than on the Macintosh platform. Microsoft also targeted other Netscape products with free workalikes, such as the Internet Information Server (IIS), a web server which was bundled with Windows NT.

Netscape could not compete with this strategy. In fact, it didn't attempt to. Netscape Navigator was not free to the general public until January 1998, while Internet Explorer and IIS have always been free or came bundled with an operating system and/or other applications. Meanwhile, Netscape faced increasing criticism for the bugs in its products; critics claimed that the company suffered from 'featuritis' – putting a higher priority on adding new features than on making them work properly. This was particularly true with Netscape Navigator 2, which was only on the market for 5 months in early 1996 before being replaced by Netscape Navigator 3. The tide of public opinion, having once lauded Netscape as the David to Microsoft's Goliath, steadily turned negative, especially when Netscape experienced its first bad quarter at the end of 1997 and underwent a large round of lay-offs in January 1998. Later, former Netscape executives Mike Homer and Peter Currie described the period as "hectic and crazy" and that the company was undone by factors both internal and external.

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 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 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 add 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 a tremendous number of unnatural links for your site" with a negative impact on site ranking.

Wikipedia   Yahoo! Search

Yahoo! is a web services provider, wholly owned by Verizon Communications through Oath Inc. and headquartered in Sunnyvale, California. The original Yahoo! company was founded by Jerry Yang and David Filo in January 1994 and was incorporated on March 2, 1995. Yahoo was one of the pioneers of the early Internet era in the 1990s. Marissa Mayer, a former Google executive, served as CEO and President of Yahoo until June 2017.



It was globally known for its Web portal, search engine Yahoo! Search, and related services, including Yahoo! Directory, Yahoo! Mail, Yahoo! News, Yahoo! Finance, Yahoo! Groups, Yahoo! Answers, advertising, online mapping, video sharing, fantasy sports, and its social media website. At its height it was one of the most popular sites in the United States. According to third-party web analytics providers, Alexa and SimilarWeb, Yahoo! was the highest-read news and media website, with over 7 billion views per month, being the sixth most visited website globally in 2016. According to news sources, roughly 700 million people visited Yahoo websites every month. Yahoo itself claimed it attracted "more than half a billion consumers every month in more than 30 languages".

Once the most popular website in the U.S., Yahoo slowly started to decline since the late 2000s, and in 2017, Verizon Communications acquired most of Yahoo's Internet business for $4.48 billion, excluding its stakes in Alibaba Group and Yahoo! Japan which were transferred to Yahoo's successor company Altaba.
