Engine Comparison
Search Engines are the most widely used tools
to search the Internet. From specific image searches to general web searches,
engines such as Google, Yahoo, and Hotbot are used by millions of people
to find information on the World Wide Web. Although these search engines
use similar methods, there are many distinct features unique to each search
engine.
|
| Google-

As one of the most popular search engine in use today, Google is bigger,
better, faster, more relevant in returns, and richer in search features
than any of its competitors (websearch.about.com). Google was born out
of a lab in Stanford in 1998, and has been growing successfully ever since.
By as early as 1999 Google was already the most popular search engine
on the web. Cnet's Ultimate Guide to Search, praises Google, “In
our tests, Google scored the highest relevancy rating and returned the
lowest number of broken links of all the sites we tested. Even Better,
we love Google’s cache function (www.cnet.com).” Using a cache
function Google actually saves a copy of each page it indexes. As a result,
Google can show copies of links that no longer exist. While this is generally
a helpful feature, users must remember that they may not always be looking
at the most recent update of a webpage (www.pcworld.com). Google Image
search is a valuable resource for searching nearly 330,000,000 images
from all over the web. This image search only enhances Google’s
reputation as a comprehensive search engine.
The real key to Googles success is it’s innovative “Page Rank”
technology. Within its full index of over 560 million pages and its partial
index of another 500 million, Google maintains high result relevance by
unique page rank technology. As explained by Don Willmont from ZD net
reviews, “PageRank evaluates how many other pages link to the pages
in its search results and assumes the pages with the most inbound links
are probably the best. The results prove the theory works (www.zdnet.com).”
Google operates with such precision that it even offers an “I’m
feeling lucky” button that takes the user directly to the first
search result site, on the assumption that this site is best suited for
the users search.
In addition to cache function and page rank technology, google also offers
benefits similar to other search engines. Google allows for both Boolean
searching and directory browsing. Google also offers a place where users
can post and read comments in Usenet discussion forums. These forums are
quite extensive, offering over 700 million messages spanning a 20 year
period, and are a useful tool for finding information about a wide range
of topics including; business, news, science,
health, recreation, and many more (google.com).

Yahoo-

Introduced in 1994, Yahoo was the first web directory and remains arguably
the most popular search site on the Internet today (websearch.about.com).
Much of its popularity is due to the careful construction and maintenance
of its web catalog. Yahoo also boasts an easy to read and intuitive user
interface design. In addition to the ease of interface, Yahoo is user
friendly because it is easy to customize. The option of “my Yahoo”
allows the user to simply customize a their page to deliver only the news
they want.
A feature important to Yahoo’s continued success is it’s indexing
strategy. Whereas many search engines use “spider” software
that crawls through the web and indexes sites, Yahoo uses human generated
site descriptions to index its web pages. This much-imitated human indexing
helps Yahoo to return relevant search results by avoiding the invisible,
and often misleading, metatags that webmasters often attach to their site
to attract hits (www.pcworld.com).
Yahoo is ideal for general searches. Unlike Google and Hotbot, Yahoo takes
the user to entire sites, rather than to specific pages. This can be very
helpful for a user that is looking for a specific page but is not sure
exactly what they are looking for within it (www.pcworld.com). Another
helpful tool that differs from Google, that Yahoo allows users to search
by categories or by web sites. This helps to narrow down search results
to make them more manageable (www.pcworld.com).

| Hotbot-

Hotbot began in 1996 as part of Wired's online services and is now owned
by Lycos. Although owned by Lycos, Hotbot is still an independent search
engine with distinct advantages and capabilities. From its homepage Hotbot
users can customize their search by date, language, category, return results,
and file type (mp3, Javascript, video, image). Users can even go further
and define an advanced search by such options as; page depth, word stemming,
word filter, and domain location. These extensive custom search options
make Hotbot a great search engine for getting specific results for a narrow
search. Such advanced search options also allow the user to search for
more than just web pages, one can search audio, video, and JavaScript
files all in one search.
Top Results on Hotbot are a result of "direct hit" technology.
Whereas it used to depend solely on Inktomi, Hotbot now uses direct hit
to return it's most popular results and inktomi to return the rest (searchenginewatch.com/sereport).
As explained in the March issue of The search engine report, "Direct
Hit is a system that measures what pages users select from search results
and roughly how long they spend visiting these pages. In a very simplistic
explanation, the more "popular" pages as measured by these factors
rise to the top of the list (searchenginewatch.com/sereport)
Each of these three search engines has its strengths; Google is best for
getting quick up to date relevant results, and Yahoo is good narrowing
search results categories before a search begins, and hotbot excels in
advanced time-sensitive searches (www.pcworld.com). Keeping these strengths
in mind, I set out to make my own personal evaluation of the sites.

Personal
Evaluations-
For my personal evaluation of Google, Yahoo, and Hotbot, I chose to search
a query that I will actually use: the Nokia 8260 cell phone. This search
is bias in its scope and subject; however, it is an effective search to
highlight some real differences among specific search engines. I started
off with two-part search to 1.) Find the official site for the Nokia 8260
cell phone and 2.) Find a site offering the purchase of an 8260 over the
internet.
With the key term “Nokia 8260”, Googles first result took me
straight to an AT&T webpage devoted exclusively to showcasing the phone
with all its specifications and features clearly listed. While this page
was helpful I would have preferred to be taken more directly to the official
8260 site posted by Nokia. Although I only checked the first 30 of the 46,000
results, while they were all relevant to the Nokia 8260, from phone reviews
to phone sales, the official site was not listed. 46,000 results is quite
an overwhelming number of results, and it is not logical to think that anyone
would actually sort through all of them, however I found even sorting through
the first 30 to be tedious, time consuming, and overall not as helpful as
expected in looking to buy a 8260. This search would have been much more
useful to a user just trying to find information on the 8260, and not actually
trying to find a particular site. Naturally in such a consumer driven medium
as the Internet in such a consumer driven society as America, a good portion
of the top results were links to purchase an 8260.
The same search on Yahoo yielded varied results. As Yahoo returns results
in a series of different categories, not just a list of links like Google,
it first gave me an “Inside Yahoo!” listing for Nokia 8260 phones
on auction, next it returned sponsor matches (search results that are paid
for by businesses or organizations) for “exclusive offers” and
“nokia accessories” available on-line, and finally Yahoo returned
4 webpage matches including one article, “Will Nokia 8260 be the number
one phone in America”, two featuring phone reviews, and finally the
official site of the Nokia 8260. I personally found these results, while
not a plentiful as Googles, to be much easier to sort through because of
their organization into categories, much more relevant, and in general very
successful in finding the official Nokia site, and helpful to me as a consumer
looking to buy an 8260.
I carried out my final search on Hotbot. The first results returned were
the same sponsored search listings as came back from Yahoo, “AT&T
exclusive online offers” and “nokia 8260 accessories”
available online. Listed next were some “search partner” links,
one for jobs with Nokia in your area, another for nokia phones up for bid
on eBay, and a final option for nokia cables available for sale on-line.
The link to e-bay may be very useful for my purchase of a phone, but the
other two seemed very random and unhelpful for my search. The web results
included 8,200 results from across the web. Out of the first 31 of these
I found relevant results that enabled me to purchase a Nokia 8260, yet no
link to the official Nokia website. An interesting feature is that HotBot
offers to run the search again with Lycos.
