Ambuiguity on checking PR

[mahd]

Hi!

Can anyone please let me know that which PR tool is best to check the PR and which can be trusted as well?

I used to check my PR from: mygooglepagerank.com

Recently, I saw various other PR tools like

iwebtool.com/pagerank_checker
checkpagerank.com
seochat.com/seo-tools/pagerank-lookup/

mygooglepagerank.com - gives me 0 PR of a page

While, the other three give 3 PR for the same page

Please clear my ambuigity on this

Thanks

i think it depends on which data center you're querying.

Here's another one for your mix:

Which is the most reliable source to check the PR?

Does Google itself provides any official tool to check PR?

Please let me know as I am confused about which result to trust.

Hello

If you use Firefox there are a couple of plug ins/add ons that check right in the browser for you.

http://www.quirk.biz/searchstatus/

The second one also displays Alexa ranking

I can not vouch for eithers accuracy.

The Google toolbar is the only authoritative way to check PR as it is the only method Google offers (their directory shows PR as well).
