With Alexa’s toolbar apparently gaining over 10 million downloads worldwide, your Alexa rank is important to a large target audience. Unlike Google’s page ranking system, the lower the number the better the page ranking and it is based on the past three months trend for your website. The rank is decided on a number of factors including page views, bounce rate and time on site (to name but a few). Again, as with Google PageRank, this is a measure that is useful as a quick and rough quality indicator.
