Tell me more about this metric
This isn’t a perfect metric as it includes a skewed sample of users. But, used over time it's still a good way to understand trends and compare sites.
Data for Alexa's reach, rank, and search analytics are collected from millions of users who have the Alexa toolbar or extension installed. As a result, Alexa is able to collect, anonymize, and track web traffic over time.
