Going Further
Web directories, such as Looksmart
and Yahoo,
are similar to search engines. At first glance they appear
to be the same, but people compile directories while web
crawlers and similar computer programs compile the databases
used by search engines. In other words, a directory is built
by someone looking at a web site to determine if it's worthy
of being added to their database and if so, under what category
it should fall. Regular search engines are not so discerning.
As you might suspect, directories don't cover as much of
the Web as a search engine, and there is the potential element
of human bias in categorization.
Many directories have search tools to help you find specific
items within each category.
Caveat about Search Engines-Directories
Sometimes, a search engine company or directory decides
to accept what are termed "paid listings". This means that
companies can pay to be displayed prominently in the search
engine results. For example, if someone types in a search
for "antique car," someone could pay to have "sellmywreck.com"
appear at the top of the results listings.
Because paid listings tamper with the credibility of search
engines, most engines avoid the practice altogether or at
least mark the results list in a way to let the user know
that someone paid to be listed first---that the first link
is not necessarily the best place to look for the requested
information.
