Agreed. As I stated, we turned off SPYW, which is the social/personalized results and the terms are rather generic for an international brand that we represent. We have been ranking highly with most of these terms very steadily for years.
My issue is with the sudden, drastic and inaccurate drops that SEOMoz is reporting but when we check, its right where it has been ranked at for months (Majority of the rankings are accurate, its only the ones that out of no where say they have a decline of over 10 spots in only a 1 week span and we didn't make any changes to the page). It just adds an extra step and a little bit more time to our internal and client reports that we could be better utilizing doing other things rather than manually double checking our rankings. We never had this problem with our previous Rank Checking Tools.
This happens with multiple client Keyword Ranking Reports.
