a month, Google
performs "The Google Dance" using results it obtained
from a "deep crawl" of your site. During this update,
which usually lasts from 3 to 5 days and starts around the end
of the month, Google recalculates your sites PR (PageRank),
back links (the number of sites which link to you), and in some
cases, recalculates where a given site appears (ranking) in the
Search Engine Results Page, AKA "SERP".
Because the Dance is so important, a lot of SEO Analysts and teckie
geeks like to know when the Google update starts so they can monitor
the results which are dynamic in nature until the update is finished
and all the changes appear in www.google.com. Click
here to view our Forum thread on the February 2003 dance which
started on March 6, 2003.
You can use our Google Dance Tool Form on this page to determine
when the Google Dance has started and monitor given terms for
your sites. Enter yourdomain.com in the first field and then click
the Search All Servers Now button. Please leave the "link:www."
in the field. You can tell if the Google Dance has started by
looking at the number of "back links" from each of the
Google servers. If the numbers are different in www verses www2
or www3 then the dance has started for your site. Click
here to see an example screen capture in a new window. If
you aren't sure if the Dance has started, use this Yahoo
quick check, which opens in a new window.
You can also enter a term in the field and see exactly how your
site ranks during the Dance in www2 and www3. Remember, these
results may change during the Dance and at the conclusion of the
Dance, the final results/data is inserted in www.google.com.
Updated: It's often helpful to know how many pages of your
site Google has indexed/listed before the Dance starts and after
the Dance has concluded. Use the following string and substitute
your own site:
Updated: Many of you have written us and asked: How do
I know when the Google deep crawl has started on my site? Carefully
examine this screen capture:
deep crawl uses an IP range of 216.239.46.x which you can view
in the screen capture. The deep crawl normally follows the Google
Dance and lasts from 3-10 days each month. Google uses the deep
crawl results for the next final update aka Dance. The Fresh Bot
aka "freshie" is not unique to the Google Dance and
often visits many sites every single day. The Fresh Bot uses an
IP range of 64.68.82.x. Examine your logs for the Deep Crawl/Bot
IP range of 216.239.46.x. Or use one of the following scripts:
Trax or GoogleStats.
Please note, you can't determine which Google Bot is visiting
your site with many stats packages, since they list both Bots
as "Googlebot/2.1" in your reports.
