“The New Alexa Rankings”
http://www.alexa.com/site/company/announcement
My site’s ranking has changed. Was it wrong before?
Your ranking wasn’t wrong before, but it was different. Alexa toolbar users’ interests and surfing habits could differ from those of the general population in a number of ways, and we described some of those possible differences on our website. While the vast majority of sites’ rankings were unaffected by such differences, we’ve worked hard on our new ranking system to adjust for situations in which they could matter.
The new rankings should better reflect the interests and surfing habits of the broader population of Web users.
