Search Engine Optimization (SEO): Major Search Engines Guide

In the search engine list below, We provides a guide to the major search engines of the web. Why are these considered to be "major" search engines? Because they are either well-known or well-used.


Google search is a web search engine owned by Google Inc. and is the most-used search engine on the Web. Google receives several hundred million queries each day through its various services. Google search was originally developed by Larry Page and Sergey Brin in 1997.

Google Search provides more than 22 special features beyond the original word-search capability. These include synonyms, weather forecasts, time zones, stock quotes, maps, earthquake data, movie showtimes, airports, home listings, and sports scores.

Google provides the option to find more than web pages, however. Using on the top of the search box on the Google home page, you can easily seek out images from across the web, discussions that are taking place on Usenet newsgroups, locate news information or perform product searching.

A Google search-results page is ordered by a priority rank called a "PageRank" which is kept secret to prevent spammers from forcing their pages to the top. Google Search provides many options for customized search (see below: Search options), such as: exclusion ("-xx"), inclusion ("+xx"), alternatives ("xx OR yy"), and wildcard ("x * x").


Yahoo! Search is a web search engine, owned by Yahoo! Inc. and was as of December 2009, the 2nd largest search engine on the web by query volume, at 6.29%, after its competitor Google at 85.35% and before Bing at 3.27%, according to Net Applications.

In addition to excellent search results, you can use tabs above the search box on the Yahoo home page to seek images, Yellow Page listings or use Yahoo's excellent shopping search engine. Or visit the Yahoo Search home page, where even more specialized search options are offered.

Yahoo! Search, originally referred to as Yahoo! provided Search interface, would send queries to a searchable index of pages supplemented with its directory of sites. The results were presented to the user under the Yahoo! brand. Originally, none of the actual web crawling and storage/retrieval of data was done by Yahoo! itself. In 2001 the searchable index was powered by Inktomi and later was powered by Google until 2004, when Yahoo! Search became independent. Yahoo! Search major competitors are: Google Search, Bing and Ask Search.

Like Google, Yahoo sells paid placement advertising links that appear on its own site and which are distributed to others. Yahoo purchased Overture in October 2003.

On July 29, 2009, Microsoft and Yahoo! announced a deal in which Bing would power Yahoo! Search.


Bing (formerly Live Search, Windows Live Search, and MSN Search) is the current web search engine (advertised as a "decision engine") from Microsoft. It went fully online on June 3, 2009, with a preview version released on June 1, 2009.

Notable changes include the listing of search suggestions as queries are entered and a list of related searches (called "Explorer pane") based on semantic technology from Powerset that Microsoft purchased in 2008. As of January 2010[update] Bing is the third largest search engine on the web by query volume, at 3.16%, after its competitor Google at 85.35% and Yahoo at 6.15%, according to Net Applications.

Ask (or Ask Jeeves in the United Kingdom) is a search engine founded in 1996 by Garrett Gruener and David Warthen in Berkeley, California. The original search engine software was implemented by Gary Chevsky from his own design. Chevsky, Justin Grant, and others built the early website around that core engine.

Ask Jeeves initially gained fame in 1998 and 1999 as being the "natural language" search engine that let you search by asking questions and responded with what seemed to be the right answer to everything. In 2001, Ask acquired Teoma's unique index and search relevancy technology. Teoma was based upon the clustering concept of subject-specific popularity.

Today, Ask depends on crawler-based technology to provide results to its users. These results come from the Teoma algorithm, now known as ExpertRank.

AOL Search

AOL Inc., formerly known as America Online is an American global Internet services and media company. AOL is best known for its online software suite, also called AOL, that allowed millions of customers around the world to access the world's largest "walled garden" online community and eventually reach out to the internet as a whole.

AOL Search provides users with editorial listings that come Google's crawler-based index. Indeed, the same search on Google and AOL Search will come up with very similar matches.The "internal" version of AOL Search provides links to content only available within the AOL online service. In this way, you can search AOL and the entire web at the same time. The "external" version lacks these links. Why wouldn't you use AOL Search? If you like Google, many of Google's features such as "cached" pages are not offered by AOL Search.


HotBot is one of the early Internet search engines and was launched in May 1996 as a service of Wired Magazine. It was launched using a "new links" strategy of marketing, claiming to update its search database more often than its competitors. It also offered free webpage hosting, but only for a short time, and it was taken down without any notice to its users. It was one of the first search engines to offer the ability to search within search results.

HotBot provides easy access to the web's three major crawler-based search engines: Yahoo, Google and Teoma. Unlike a meta search engine, it cannot blend the results from all of these crawlers together. Nevertheless, it's a fast, easy way to get different web search "opinions" in one place.


AlltheWeb is an Internet search engine (Powered by Yahoo) that made its debut in mid-1999. You may find AllTheWeb a lighter, more customizable and pleasant "pure search" experience than you get at Yahoo itself. The focus is on web search, but news, picture, video, MP3 and FTP search are also offered.

AlltheWeb had a few advantages over Google, such as a fresher database, more advanced search features, search clustering and a completely customizable look.
