Reach per Million Users
What is Reach per Million Users?
Reach is an Alexa Web Search metric that measures the number of people who have the Alexa toolbar or extension installed and who saw your content. If your website has a Reach score of 5,000, this means that 5,000 people out of a sample of 1 million, who have the toolbar or extension installed, saw your site yesterday.

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.
