AllTheWeb

Powered by Yahoo, AllTheWeb has one of the largest search engine databases in the world. Quite possibly the largest search engine database in the world. Achieving and maintaining good search engine placement and position with AllTheWeb is essential.

AllTheWeb.com has the fastest average response of any search engine out there, coming in at under a half a second per search. AllTheWeb combines the largest and freshest search engines and includes some of the most powerful search features in the search engine industry.

The AllTheWeb search engine index includes billions of web pages as well as tens of millions of PDF and MS Word® files, and supports searching in 36 different languages.

Alta Vista

AltaVista is owned by Overture, which Yahoo! purchased in July 2003. AltaVista is powerful and it's fast, mainly used for pinpoint searching of narrow topics and people in the news. It is popular because it successfully narrows search topics.

Alta Vista is one of the most inclusive search engines, although not necessarily the best search engine for every use. AltaVista's main or organic results are supplied by Yahoo!, sponsored listings are from Overture, and the directory listings are provided by DMOZ Open Directory Project .

AOL

America Online natural and sponsored search results for AOL are provided by Google Search, while the main directory results come from DMOZ Open Directory Service; which is also owned by AOL. When there are no available results from one of these search results providers, AOL receives it's secondary search results from Inktomi.

AOL takes Google's site listings and then uses their own algorithm to reorder the search results, and uses Google's Adwords product for sponsored entries. The bottom line is that although the top 25 search results with AOL will generally be pretty similar to Google, you can't assume it because AOL will sometimes throw a listing or two of their own into the mix.

Ask Jeeves

Ask Jeeves is a human-powered search engine service that aims to direct you to the exact page that answers your question. If it fails to find a match within its own database, then it will provide matching web pages from various search engines. The service opened fully in June 1997. AskJeeves receives its organic search results from the Teoma Search Engine Index, but it also uses Google's Sponsored Listings.

Ask Jeeves' search and search-based portal brands include: Ask Jeeves (Ask.com and Ask.co.uk), Ask Jeeves for Kids (AJKids.com), Excite (excite.com), iWon (iwon.com), My Search (mysearch.com), My Way (myway.com), My Web Search (mywebsearch.com), and Teoma (teoma.com).

Excite

The Excite Network is the sixth most trafficed web property according to the Nielsen Net Ratings and includes two premier portals, iWon and Excite.

Currently a property of AskJeeves Inc, Excite is one of the most recognized names in online search, and is among the Internet's most personalized portals featuring a completely customizable home page. Excite search features a host of comprehensive search tools, a popular webmail platform with robust content and resources from over 100 leading providers.

GO

The Go Network is the Internet business of the Walt Disney Company, and manages some of the Internet's most popular web sites, including the GO.com portal.

Google

Google is a search engine that makes significant use of link popularity as a primary way to rank web pages. This can be especially helpful in finding good sites in response to general searches because users across the web have in essence voted for good sites by linking to them.

The PageRank System works so well that Google has gained wide-spread praise for its high relevancy.

Google not only maintains its own spider-based index, it has a directory powered by the Open Directory Project that is ranked according to Google's link popularity technology.

Hot Bot

HotBot is a favorite among researchers due to its many powerful searching features. In most cases, HotBot's first page of results comes from the Yahoo! Search Engine Service, while sponsored results come from Google Adwords.

HotBot also receives its directory listings from the Google Directory which is the DMOZ Directory ranked using Google's PageRank System. Secondary listings are provided to HotBot by Inktomi.

Inktomi

Inktomi is not a search engine, but a searchable database. Founded in 1996, with core search technology based on a research project at UC Berkeley that harnessed the power of parallel computing.

The Inktomi Corporation is a wholly owned subsidiary of Yahoo, and is the leading provider of OEM Web Search and paid inclusion services. Inktomi doesn’t use any search engine results but its own, however, they do supply secondary results to AOL, Overture, MSN and HotBot.

iWON

iWon is the Internet's leading loyalty-based search portal combining world-class search, content and functionality with the Internet's largest guaranteed cash giveaway and loyalty program.

Looksmart

LookSmart Search provides partners and search users with industry-leading search results through the unique combination of proprietary search technology, a web index and a professionally edited directory.

LookSmart's proprietary search technology, branded under the trade name of WiseNut, makes use of textual analysis of hyperlinks, web page popularity, user feedback, and editorial input to provide search results with leading relevance.

Integrating a traditional centralized crawling framework and a paradigm-shifting distributed crawling model, LookSmart has built WiseNut into one of the web's largest web search engines, including 2.5 billion URLl's and 1.1 billion indexed documents.

Lycos

Lycos Search still uses the Open Directory for data, but it’s been moved from their front page to a subdirectory, and it doesn’t get updated very frequently. Their main directory uses a number of different resources, for example their Health information is powered by WebMD.

MSN

MSN Search used to receive its search results from a variety of sources. The "Featured Sites" section search results were provided by MSN's sponsors. The results in the "Web Directory Topics" and "Web Directory Sites" sections came from Overture, one of MSN's primary providers. Inktomi "Web Pages" results were also used.

Things have changed at MSN Search in 2005. The new MSN Search includes a new search engine, index and crawler; all built from the ground up using Microsoft technology. With this new search service, you can find what you're looking for fast. From this MSN Search page you can find out how to use some of their advanced features, how the new MSN search engine works, as well as how to submit your site to the new MSN search.

Netscape

Netscape Search results come primarily from Google, receiving organic, sponsored and secondary listings from Google and Google’s Adwords Program. Netscape also receives its directory listings from DMOZ Open Directory Project.

Netscape uses Google Search by default, although you can search using a number of other search engines from the Netscape search bar. The sponsored section is provided by Google’s Sponsored Links.

ODP Open Directory Project

The ODP, short for the "Open Directory Project" (also known as DMOZ) uses all volunteer editors to catalog the web. Formerly known as NewHoo, DMOZ was launched in June 1998, and acquired by Netscape in November 1998. The company pledged at that time to allow access to the directory through an open license arrangement with Netscape itself being the first licensee.

Since then, AOL has acquired Netscape and now owns DMOZ. Many search engines have devoted their directory results to DMOZ's listings. Included in those who use the DMOZ directory for their search results are TerraLycos, AOL, AltaVista, Google, MSN, and Netscape.

DMOZ is almost impossible to get listed in because of the issues with using volunteer editors. Becoming a volunteer editor is now next to impossible, and unfortunately that's left DMOZ very out dated. There are not enough editors to service all the URLs submitted for consideration and there is a great deal of favoritism amoungst those who are editors ... even rumors of bribary and corruption amoungst some of the editors. DMOZ needs help in our opinion.

Overture

Unlike other major search engines on the web, Overture is Paid Inclusion which sells its main listings to companies willing to pay to be placed higher in the search results on a bid for position basis. Debatable as it may be, Overture insists that this type of paid inclusion actually improves relevancy.

In April of 2003, Overture acquired AllTheWeb and AltaVista. Not long after that , Overture itself was acquired by Yahoo!, which means Yahoo now owns AllTheWeb, AltaVista, Overture and a host of other search related proverties such as Inktomi Corp. which is a wholly owned subsidiary of Yahoo and the leading provider of OEM Web Search and paid inclusion services.

Teoma

Teoma Search Technology measures the authority as well as the popularity of web sites, and powers Ask Jeeves as well as its own search engine. Teoma was bought by AskJeeves and merged with DirectHit in early April 2002.

Teoma gets its sponsored results from Google Adwords. It also sends out organic search results to AskJeeves as well as directory listings to HotBot.

Unlike many other crawlers, Teoma has no free "Add URL" page however, this doesn't mean that you can't get listed. Teoma crawls the web, so if you have links pointing to your web site, you may get included naturally.

Teoma and AskJeeves Paid Inclusion is one and the same.

Webcrawler

WebCrawler Meta Search is a powerful meta-search engine that searches multiple leading search sites to find the results you're looking for, and it's fast. With one single click, WebCrawler searches the best results from the combined pool of the world's leading search engines instead of just search results from a single search engine source.

WebCrawler's Meta-search Technology highlights the strengths of many of the web's major search properties such as Google, Yahoo!, About, LookSmart, Overture, Teoma, FindWhat, Ask Jeeves and Inktomi, thus delivering more relevant and comprehensive search results every time you search.

Take a crash course in Meta-search.

WiseNut

Like Teoma, WiseNut is a crawler-based search engine that attracted attention when it appeared on the scene in 2001. Also like Teoma, WiseNut features good relevancy. Unlike Teoma, WiseNut has a large database, making it nearly as comprehensive as Google Search, AllTheWeb and Inktomi.

Yahoo!

Yahoo is both a human-edited directory and a spider-based search engine index. Google used to provide the spider-based index, but in April 2004, Yahoo stopped working with Google to use their own newly developed Yahoo Search Program.

Today, Yahoo has millions ow web sites listed, and it supplies organic search results for many search engines, including AltaVista, AllTheWeb and HotBot. Yahoo's sponsored results still come from Overture.
