Why are the rankings of my keywords different to rankings from other programmes such as 'Access my Lan' and 'Firefly'? Does SEOMoz count 'Google Places and Maps' in their rank count? Im thinking this could explain the difference

Does SEOMoz count 'Google Places and Maps' in their rank count?

The search engines - Google, Yahoo! & Bing - all maintain multiple indices that run across multiple datacenters. This means if you query different datacenters, you can get somewhat different ranking results. Other elements, such as personalization, geography and search history (even if you're logged out of your Google/search engine account) can also influence ranking positions. Hence, 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, showing what the "most" users see, though we know there's still quite a bit of room for fluctuation. If you have suggestions about how we might improve the technical process of fetching rankings data to get better data, please let us know and we'll pass it on to our engineering team. We're always looking for ways to get you better data.

We also do not count universal results towards this ranking. Instead, these universal results are handled differently. To learn more about rankings and universal results check out www.seomoz.org/help/rankings

Let me know if you have any addition questions or concerns.
