G search results question

Hi all,

I am a bit confused about the results for a specific keyword in the big G.

Using IE with the US G my site is ranked position #12, using FF also the US G my site is ranked position #2 (i have seoquake addon), when I log into gmail, in IE I have the position #6, in FF #18.

Could you recommend any tips, how to check my rankings without any software, as it makes me crazy lately.

Thanks in advance!

Personally I use sescout.com
It allows you to track 10 keywords for free. Works fine for me.

thanks, I will try it out!
