Hey ,
Here are some of major Search Engines and Web Directories …

Google (http://google.com)

A Search Engine, inclusion in which is free. it’s the world biggest . It’s highly recommended as a first stop in your hunt for whatever you are looking for.

Yahoo (http://www.yahoo.com)

Launched in 1994, Yahoo is the web’s oldest “directory,” a place where human editors organize web sites into categories. However, in October 2002, Yahoo made a giant shift to crawler-based listings for its main results. These came from Google until February 2004. Now, Yahoo uses its own search technology. Learn more in this recent review from our SearchDay newsletter, which also provides some updated submission details.

The Yahoo Directory still survives. You’ll notice “category” links below some of the sites lists in response to a keyword search. When offered, these will take you to a list of web sites that have been reviewed and approved by a human editor.

It’s also possible to do a pure search of just the human-compiled Yahoo Directory, which is how the old or “classic” Yahoo used to work. To do this, search from the Yahoo Directory home page, as opposed to the regular Yahoo.com home page. Then you’ll get both directory category links (”Related Directory Categories”) and “Directory Results,” which are the top web site matches drawn from all categories of the Yahoo Directory.

Sites pay a fee to be included in the Yahoo Directory’s commercial listings, though they must meet editor approval before being accepted. Non-commercial content is accepted for free. Yahoo’s content acquisition program also offers paid inclusion, where sites can also pay to be included in Yahoo’s crawler-based results. This doesn’t guarantee ranking, Yahoo promises. The CAP program also bring in content from non-profit organizations for free.

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

Overture was formerly called GoTo until late 2001. More about it can be found on the Paid Listings Search Engines page. Overture purchased AllTheWeb in March 2003 and acquired AltaVista in April 2003. Now Yahoo owns these, gained as from its purchase of Overture.

Technology AltaVista and AllTheWeb was combined with that of Inktomi, a crawler-based search engine that grew out UC Berkeley and then launched as its own company in 1996, to make the current Yahoo crawler. Yahoo purchased Inktomi in March 2003.

AOL Search http://search.aol.com/
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.

Ask Jeeves (AJ) (http://ask.com)
Search Engine part of the Teoma Search Engine Network. AJ has a paid inclusion / paid listing program.

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. Today, Ask Jeeves instead depends on crawler-based technology to provide results to its users .

Ask Jeeves also owns now closed Direct Hit service.
DMOZ ( http://dmoz.org )
Web Directory edited by human editors. Also known as ODP (Open Directory Project). Provides directory results to Google and other search engines. It is considered very important from the Search Engine Optimisation view and it is also the most tedious and difficult to get in.

HotBot  (http://hotbot.com )
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.

Teoma   (http://teoma.com )
Teoma is a crawler-based search engine owned by Ask Jeeves.

LookSmart (http://search.looksmart.com )

LookSmart is primarily a human-compiled directory of web sites, very much like an electronic “Yellow Pages “  .

Lycos (http://lycos.com)

MSN (http://www.msn.com )

Microsoft Network A Search Engine.

MSN Search is in transition. It provides access to Yahoo listings but not as much functionality in terms of other types of searches that you’ll find at Yahoo itself, MSN is developing its own crawler-based technology .

ODP (Open Directory Project) : Web Directory edited by human editors

And many others. …
