Search Engines and Directories
Many search engines update their index either on a monthly or
bi-monthly basis. When Web searchers use a search engine to locate
Web sites that are relevant to the keyword search, they are searching
the SE's index.
Google, Inktomi, AltaVista, AlltheWeb and the like are all forms
of search engines. These search engines write programs known as
robots or spiders or crawlers that have the following functions:
- locate Web pages
- read the contents of the Web pages and
- report its findings back to the search engine's indexes or
databases.
Yahoo!, Open Directory Project and the like are all forms of
Web directories. These directories use human editors to review
sites that are submitted for submission to the directory. Directories
use a hierarchical tree structure to organize their database.
A directory will list Web site root home pages. A search engine
will list individual pages of a Web site.
Search Engines and Directories are listed here in order of the
most highly recommended first.
Google
Google.com is
highly recommended as a first stop in your hunt for whatever you
are looking for. Voted three times Most Outstanding Search Engine
by Search Engine Watch readers, Google has a well-deserved reputation
as the top choice for those searching the Web. The crawler-based
service provides both comprehensive coverage of the Web along
with great relevancy.
All The Web
If you tried Google and didn't find it, AllTheWeb.com
should be next on your list. An excellent crawler-based search
engine, AllTheWeb provides both comprehensive coverage of the
Web and outstanding relevancy. Indeed, it's a first stop search
engine, for some. In addition to Web page results, AllTheWeb.com
provides the ability to search for news stories, pictures, video
clips, MP3s and FTP files.
Yahoo
Yahoo.com
Express Site Submit requires a submission fee or the "Standard"
which is free. Anyone can use Standard submission to submit for
free to a non-commercial category. If you use the free submit
choice, there's no guarantee that your submission will be reviewed
quickly or at all. Consider Yahoo any time you think you might
be well served by having a list of human-reviewed Web sites. It's
also a good choice for popular queries, since the category listings
it provides may help you narrow in and refine your query. In October
2002 Yahoo made a giant shift to using Google's crawler-based
listings for its main results.
MSN Search
search.MSN.com
provides a blend of human-powered directory information and crawler
coverage different from any of the other top choices listed above.
It's a high quality resource that provides its own unique view
of the Web and one worth checking. MSN Search also relies on search
providers for answers to many of its queries. Usually, it will
be human-powered results from the LookSmart directory that dominate
the page. For more obscure queries, it is crawler-based results
from Inktomi that are provided.
DogPile
Dogpile.com
offers paid listings only, and searches Yahoo!, Lycos' A2Z, Excite
Guide, World Wide Web Worm, WWW Yellow Pages , PlanetSearch, What
U Seek, Magellan, Lycos, WebCrawler, InfoSeek, AltaVista, Excite
& HotBot. Dogpile Meta-Search allows you to search multiple
leading search engines at once, returning more comprehensive and
relevant results fast, unleashing the power of meta-search.
AOL Search
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. So, why would you use AOL Search?
Primarily because you are an AOL user. 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.
Ask Jeeves
AskJeeves.com
For the main editorial listings at Ask Jeeves, you need to be
listed with Teoma. Paid Listings come from Google AdWord. Ask
Jeeves initially gained fame in 1998 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.
Ask Jeeves depends on crawler-based technology to provide results
to its users. These results come from the Teoma search engine
that it owns.
HotBot
HotBot.com
In order to submit your site, you will need to be validated as
an member user. For the main editorial listings at HotBot, you
need to be listed with the four major crawlers it queries. HotBot
provides easy access to the Web's four major crawler-based search
engines: Google, AllTheWeb, Inktomi, and Teoma. It's a fast, easy
way to get different Web search "opinions" in one place.
HotBot debuted in May 1996, it gained a strong following among
serious searchers for the quality and comprehensiveness of its
crawler-based results.
Lycos
Lycos.com
For the main editorial listings at Lycos, you need to be listed
with AllTheWeb. Paid listings come from Overture. Lycos is one
of the oldest search engines on the Web, launched in 1994. It
ceased crawling the Web for its own listings in April 1999 and
now uses crawler-based results provided by AllTheWeb.
Teoma
Teoma.com
will guarantee to include your pages if you use its Ask Jeeves
Site Submit paid inclusion program. It will get new pages listed
in a week. It is recommended that new sites use the program to
get their home pages quickly listed. The cost is $30 and means
that the page will be revisited each week, for up to a year. Teoma
is a crawler-based search engine owned by Ask Jeeves in September
2001. It has a smaller index of the Web than its rival crawler-competitors
Google, AllTheWeb, Inktomi, and AltaVista.
Inktomi
Inktomi.com
Use the Search Submit program to get at least your home page listed,
for a $39 fee. Paying the fee is really only speeding up the process
of getting the home page listed, for a brand-new site. Among the
major search engines, Inktomi is the second-oldest crawler. It
briefly operated as an experimental search engine at UC Berkeley.
However, the creators then formed their own company in 1996 with
the same name and gained their first customer, HotBot, in the
middle of that year. Inktomi was purchased by Yahoo in March 2003.
LookSmart
LookSmart.com
As with Yahoo, LookSmart has a free submit option for its non-commercial
categories and a paid option for its commercial sites, who pay
to be listed in commercial categories, making the service very
much like an electronic "Yellow Pages". LookSmart is
a human-compiled directory of Web sites that provides its results
to other search engines that need listings.
Overture
Overture.com
is the oldest and most important paid placement search engine,
because it distributes its listings to a wide-range of major search
engines, including AltaVista, AOL Search, Lycos, HotBot and Netscape
Search. Non-paid results at the Overture site itself come from
Inktomi. Overture launched as "GoTo" in 1997 and incorporated
the former University of Colorado-based World Wide Web Worm. In
February 1998, it shifted to its pay-for-placement model. The
company changed its name from GoTo to Overture in October 2001.
AltaVista
AltaVista.com
is the oldest crawler-based search engine on the Web. It opened
in December 1995 and for several years was the "Google"
of its day, in terms of providing relevant results and having
a loyal group of users that loved the service.AltaVista was originally
owned by Digital, then taken over by Compaq in 1998. AltaVista
was later spun off into a private company, controlled by CMGI.
Overture bought AltaVista in April 2003.
Netscape Search
search.Netscape.com
Netscape essentially duplicates the editorial and ad listings
that are shown on Google, so you need to be listed with Google.
Owned by AOL Time Warner, Netscape Search uses Google for its
main listings.
WiseNut
WiseNut.com
There is no current submission system for WiseNut. WiseNut is
a crawler-based search engine that attracted attention when it
appeared on the scene in 2001. WiseNut has a large database, making
it nearly as comprehensive as Google, AllTheWeb and Inktomi.
