Can Alexa ratings/rankings be trusted?
jacquesm: I think all 'free' online ranking sites give you data that you should take with a large grain of salt. You can use some of them for relative comparisons but not if the comparison is a close one.Another use is to extrapolate from 'known' numbers to an unknown site (say a competitor).It helps to separate truth from bull, but it is definitely not an exact measurement. If someone is off by a factor of 10 then you're on solid ground to call bull, if it is a factor of 2 or less then it gets a lot harder.
