How reliable is Alexa in measuring your site’s traffic rank?
Even to someone like me who enjoys browsing over site statistics and testing the accuracy of the resulting metrics, understanding an Alexa traffic rank is not an easy task.
Except for the fact that the Alexa traffic ranking system is based on information generated from Alexa toolbar users and that “A site’s ranking is based on a combined measure of Reach and Page Views” plus some kind of “data normalization” which also are not explained, there is not much information about the Alexa ranking system.
