Classifications of Search Engines
With a decent understanding of how search engines
work and how people use those search engines, you can now concentrate
on some more detailed information about these engines. For example, you
already know that all search engines aren't created equal, but did you
know that there are different types, or classifications, of search
engines? Read this secret seo tutorial below
A primary search engine is the type you think of
most often when search engines come to mind. Some index most or all
sites on the Web. For example, Yahoo! Google, and MSN are primary (also
called major) search engines.
Primary search engines generate the majority of
the traffic to your web site, and as such they will be the primary
focus of your SEO efforts. Each primary search engine differs slightly
from the others. For example, Lycos has been around much longer than
Google, yet Google is the most popular search engine on the Web. Why is
that? Most likely, it's because people find that Google provides better
The difference between those search results lies
in the search algorithm used to create the search engine. Most primary
search engines are also more than just search. Additional features such
as e-mail, mapping, news, and different types of entertainment
applications are also available from most of the primary search engine
companies. These elements were added long after the search feature was
established as a way to draw increasing numbers of users to the search
engine. Although those features don't change the way people search,
they might affect which search engine people choose.
Each of the major search engines differs in some small way. Google is
the king of search engines, in part because of the accuracy with which
it can pull the results from a search query. Sure, Google offers all
kinds of extras like e-mail, a personalized home page, and even
productivity applications, but those value-added services are not what
made Google popular.
What turned Google into a household word is the
accuracy with which the search engine can return search results. This
accuracy was developed when the Google designers combined keyword
searches with link popularity. The combination of keywords and the
popularity of links to those pages yields a higher accuracy rank than
just keywords alone. Of course, it also helps that Google places paid
advertisements in a separate part of the page, as obvious ads, and not
as part of the actual search results.
However, it's important to understand that link
popularity and keywords are just two of dozens of different criteria
that search engines can use in ranking the relevancy of web pages.
Most people know that Yahoo! is a search engine,
but it's also a web directory, which basically means that it is a list
of the different web pages available on the Internet, divided by
category and subcategory. In fact, few people know that Yahoo! started
as the favorites list of the two young men who founded it.
Through the acquisition of companies like Inktomi,
All the Web, AltaVista, and Overture, Yahoo! gradually gained market
share as a search engine. Yahoo!, which at one time used Google to
search its directory of links, now ranks pages through a combination of
the technologies that it acquired over time. However, Yahoo!'s
link-ranking capability is not as accurate as Google's. In addition,
Yahoo! has a paid-inclusion program, which some users think tends to
skew search results in favor of the highest payer.
MSN's search capabilities aren't quite as mature as those of Yahoo! or
Google. As a result, MSN has not yet developed the in-depth link
analysis capabilities of these other primary search engines. Instead,
MSN relies heavily on web site content for ranking purposes. However,
this may benefit new web sites that are trying to get listed in search
engines. The link-ranking capabilities of Google and Yahoo! can
preclude new web sites from being listed for a period of time after
they have been created.
This is because (especially where Google is
concerned) the quality of the link may be considered during ranking.
New links are often ignored until they have been in place for a while.
Because MSN relies heavily on page content, a web site that is tagged
properly and contains a good ratio of keywords will be more likely to
be listed — and listed sooner — by the MSN search engine. Therefore,
though it's not the most popular of search engines, MSN is one of the
primaries, and being listed there sooner rather than later will help
increase your site traffic. read more at
