Even though Alexa as we know isn't accurate and only good to find out the general popularity of a site, has anyone come up with a formula or scale to make alexa ratings work for them when analyzing a site's popularity/unique users?



eg. 3 month avg Alexa rank of 20,000k is proportional to 1,000 unique users a day on avg...?

What is your guys' proportion of your Alexa rating vs unique users?

Also how many uniques would you think a 15k rating would have?
