Reply #40: a better analogy would be… [View All]

a poll of 400 people who use rotary dial phones… which would represent a very small and unrepresentative percentage of the overall population.

the day after the Clark campaign announced that their one-day traffic had surpassed Dean's traffic on that day (about a month ago) Mathew Gross (Dean's webmaster) e-mailed reporters traffic reports from some of the widely-respected traffic monitoring companies they use. those results flew in the face of what Alexa was reporting. he also included a detailed explanation as to the deficiencies in Alexa's methodology (which are many… in addition to the fact that they only monitor Alexa users).

unfortunately I don't have a link handy to any of the articles that discussed this.

I would suspect that most of the companies using Alexa's commercial traffic measurement services are relatively small and can't afford any of the bigger and more repectable companies.

I can practically assure you that Amazon doesn't rely on Alexa for their traffic reports.
