Are there discrepancies between GWT and SEOMoz?

[NaHoku]

In our keyword rank tracking report, we've dominated a keyword in Google and have secured the slot for years.  All evidence points in this direction.  In Google Webmaster Tools, however, this particular keyword averages a rank of 6.5.  Is anyone else experience these kinds of discrepancies?  What is your take on it?

The scope of data Google has ( i would not expect them to show all that to user through GWT ) and OSE has are not the same so there will be some discrepancies, here and there .

Everything is way off.  Even our company name according to GWT is ranking at an average of 4.5.  Does GWT also include universal results in their ranking report?

If I remember correctly, Google is doing an average of all of the pages that rank for that term. So if your privacy policy ranks in 20th position for your company name, that gets factored in. I think that's how it works, but could be wrong. It should be a place to start looking for information though.

That makes MUCH more sense.  I'll Google it a bit and see what others have to say.  Thanks Keri!
