Alexa Rank Spank?

April 18, 2008

Recently Alexa made a “big change” to their ranking algorithm. They now “aggregate data from multiple sources to give you a better indication of website popularity among the entire population of Internet users.”

I know this sounds like a better way of calculating an accurate rank, however, there is no knowing what “additional sources” they are using. You used to be able to calculate their bias based on the fact that you knew that their rankings came from users with the Alexa toolbar. You were able to gage the type of user that would have such a device, and have a better understanding of your ranking amongst those users.

Where do these new sources of user information come from?

Most of the sites that I work with have dropped significantly:

Conclusions:

  1. Where ever Alexa is getting their Internet usage stats from now, I can tell that they have less of an interest in Tourism Technology then the former data pool.
  2. Changing your domain (tourismtide.blogspot.com to tourismtide.com) can be painful. Both my Alexa and my Technorati were destroyed.

Have you noticed a change in your rank? Do you know where Alexa is getting their new user statistics from?
