Everybody connected
to the Web has heard
the term “Search
Engine Spider.”
From its name, its
not difficult to
understand its
nature in general,
but let’s
investigate it in a
bit more detail. A
Search Engine Spider
(also known as
“robot”,
“crawler” and
“worm”) is an
integral component
of Crawler-based
Search engines as it
separates them from
another type of
search engines –
Human-powered.
Crawler-based search
engines observe
websites with the
help of special
programs called
“search engine
spiders.” They
surf the infinite
space of the
Internet looking for
the recently created
pages and for
updates of the pages
already indexed.
Search Engine
Spiders crawl their
way through links
both inside the site
and between
websites. If your
site has no incoming
links, the only way
to invite the Search
Engine Spider is to
take advantage of
suggestion the site
by yourself; the
majority
Crawler-based search
engines allow it.
The information
gathered by Search
Engine Spiders gets
to the Index – the
second element of
Crawler-based search
engines. Index is a
huge knowledge box,
concentrating the
copies of all the
pages found by
Search Engine
Spiders treated as
relevant by Search
Engine. However,
don’t take for
granted that if the
page is found by
Search Engine
Spider, it will be
indexed promptly.
The third element of
every Crawler-based
Search Engine is the
software, which
scans the Index and
presents the
consecutive list of
the most relevant
pages on your query.
As Search Engine
Spiders constantly
surf the Web, they
inform the Index
about changes, which
influences on the
posterior ranking
according to the
cherished
Algorithm.
Of course, every
Search Engine has
its own algorithm,
and all Search
Engine Spiders are
tuned differently.
However, if you
desire to rank
highly in
Crawler-based search
engines, just
remember that the
value will be given
not by a man and
that even the
unsurpassed design
will not be
appreciated by
impartial Search
Engine Spider.
