I have been using the Googlerankings tool recently to check on my page
position of my website home page for various key words. For the one key
word(s) that I use, The results I get say position #570 (out of
12,600,000) or so depending on the day. When I search via Google
however, my web page is nowhere to be found.

I understand that the Googlerankings tool queries a different data
center and/or gets its results from a different location than
Google.com actually does, and Ive actually found the IP for that
location and have been able to verify the page position of 570 (out of
12,600,000) there. However I am unable to find any results at all in
any of the other Google locations for the keyword im using (I used the
google-dance tool).

Its been about 5-6 days now and I am still not showing up in any
Gooogle searchs for that keyword except for in the one location that
googlerankings gets its results from ? Is this cause for concern or
will the data eventually get propogated to the other locations ? (My
whole website is indexed and I am getting good page position using
other key words)

thanks,
