Welcome to the Q&A Forum

Hi there, Thanks for the question! The answer is that Moz actually uses more robust depersonalization methods when querying for Google rankings. Our process completely strips personalization to provide a result that is more representative of a national average for all searchers in the country. You may not be able to reproduce these exact SERPs within your browser even if you used incognito, because your location is factored into your search results. So, there can be a lot of variation in what different people, searching from different computers/locations, might see in the rankings. Our solution has been to run searches from a variety of IP addresses and IP blocks using non-personalized, search history/location-agnostic requests. In our experience, these have provided the most accurate results. I hope that clears up how that works!
