2. The update of the Google index is often referred to as the
Google dance. For several days when Google is updating
their index to include new pages and update their
algorithms, search results almost seem to take on a life of
their own. High positioned sites have been known to drop
into near obscurity while the lesser-judged sites suddenly
find themselves careering towards dizzy heights in the
rankings. While this phenomenon is usually relatively
short lived, lasting only two or three days, many
webmasters take it to be a sign of things to come during
the next major update.
4. Google uses a number of patented algorithms to
determine the exact ranking of every indexed website.
They also attempt to index as many websites and pages as
they can possibly find. In order to do this they utilize tens
of thousands of different hosts and over a dozen data
centers. It is impossible for Google to update each and
every one of these at the same time and it is also
impossible for them to alternate between using old data
and the new updated data. This leads to some potentially
skewed results in their listings. However, these results are
not usually indicative of future rankings.
8. The logic is fairly simple. The PR of your site is a numerical
value determined by numerous factors including the
number of inbound links. In no way can this numerical
ranking indicate the relevance of your website content
when looking at a particular search term. Having a PR6
website does not necessarily mean that your site bears
more relevance to a particular term than another website
with a PR2. So, as well as the PR of your website, Google
must also consider the topic and the content of your site
and how relevant this is to the relevant search term.
12. During the time the Google dance is being completed, the
servers located around different data centers are
upgrading and updating one at a time. This is why some
sites will show spurious results and why some webmasters
benefit for a day or two while others lose out. There is
absolutely nothing that can be done to prevent this
Google phenomenon and there is nothing you can do to
hurry the process up. All that is left is to sit back and
watch in amazement as the Google index dances.
