Understanding The Google Dance
Anton Cheranev
What’s the Google dance? Well, it’s really just a fun phrase
for when Google updates its index. This occurs regularly, once
a month, and can cause a lot of movement in rankings, meaning
that it’s come to be feared by many in the SEO industry and
anticipated by others. The update isn’t just one sudden switch,
though, as each index update takes several days to complete.
During this update the searches seem to ‘dance’ between the old
index and new index – that’s the Google dance.
So why does it happen? Well, Google pulls its results from over
ten thousand servers, and they can’t all be updated at once –
Google would have to go down for the update. Instead, each
server is updated with the new index, one at a time. This can
cause very strange behavior in the page rank process if two
major sites located on separate servers happen to have a close
linking bond. These sorts of separations are interesting and
can contribute to a great deal of change and motion in page
ranks. The most important thing to keep in mind is that
eventually Google will get you into your proper place.
Generally, if you behave, you will not be thrown down for long
by the odd activity that can occur when Google is in the
process of updating its index for your server (or for the
servers of your favorite link partners.
One common misunderstanding is the idea that Google controls
which server each kind of information is coming from, and so
stores similar information on the same server. Google’s index
doesn’t work this way – it’s a big, disorganized mass of
information that Google searches very quickly. This is a
blessing in disguise because it allows your site to remain
reachable via other sites that are related to it when the index
is taking place. Your site generally won’t suffer for too long
when an update is taking place anyway, but if you are heavily
dependent on Google results, you will see a slight drop for a
short period of time. This drop is often followed by a slight
spike especially if your page rank has increased since the last
index.
The 10,000 servers that Google uses are distributed between
seven datacenters all over the world. Google doesn’t keep all
of those eggs in one basket – they want to be able to lose one
datacenter and have the rest survive. If part of Google goes
down, people can still use the search engine and as I said
before, this allows your site to be accessed via related sites
if the server holding your sites index happens to go down. The
datacenters that Google has put into play are enormous in
comparison to most datacenters around the world. Google rivals
some of the largest datacenters in the world with each of its
datacenters and is probably the largest in the world if all
were combined into one.
You see, the ‘time-to-live’ for www.google.com is only five
minutes – that means that Google’s IP address can change every
five minutes. This allows them to switch between their
datacenters regularly, spreading the search load between them
intelligently and routing around any damage. If you constantly
entered the same datacenter with every search that you placed
it would almost certainly fry within twenty four hours.
Considering the number of users on Google each and every day,
it is surprising that ten thousand servers is enough. A server
can only handle so much traffic in a day and Google insures
that it can hold more than any other service on the internet.
The datacenters updating their indexes at different times
causes Google to do its dance. Unless you’re looking for your
website’s ranking, you’d never notice this as your site is
normally available at all times. The unfortunate bit is that
often times you will lose your page ranking for a short period
of time or your site will seem to have a lower number of pages
indexed by Google. If you insure that you have several hundred
pages available on Google at all times you will most likely be
able to provide all of your content at all times either
directly or indirectly.
