LINK
PLACEMENT
Going
Too Deep
When
you are looking for a good link partner, after
looking at the content of the site, the next
important aspect is the location of that
site’s links page. Ideally the links page should be no more than two or three
clicks into the site.
If the links page goes too far into the
site, then you are at risk of entering the
invisible web.
This is important because the invisible
web also referred to as the “Hidden Web,”
and or the “Deep Web,” is an area of the
Internet which search engines do not
automatically search.
The
information found in the hidden web is
available.
However, it cannot always be located
through a normal search request, making the
information invisible.
In other words, for a search engine to
locate the information the search engine will
have to work harder and dig deeper to retrieve
the information.
To
understand why this is a problem you first have
to take a good long look at the Internet.
First of all everyone wants to surf the
Internet fast.
The faster the better and search engine
are no different.
Search engines often send out crawlers,
which are also know as bots and spiders to
index websites. Spiders are usually programmed
to locate sites on the Internet to use on
search engine results pages so that the next
time you do a search the website will be there.
In addition, these spiders also
periodically go back to website to ensure that
still exists and the content is still relevant. However, if the content is too deep in the website, the
spiders seldom locate the information, thus
making the information practically invisible.
It is important to understand that there is information and
web pages that are located in the deep web
because they are for purely technical purposes.
However, it is equally important to understand
that these spiders are not able to reason or
think on their own, that they are strictly
programs created to go from link to link
searching for relative content.
When
the spiders encounter websites that require
password access, or that have been created
without the usual HTML, then the spiders may
not be able to read the data.
An example of this is a PDF document,
which may be accessed as a link but is not
often found as an HTML web page.
Search engines are continually updating their search
techniques in order to access the deep
invisible web. Perhaps as search engines create
better techniques to search and retrieve
information, the information in the deep web
will become more accessible.
