Alexa rank is a measure of website popularity. It ranks millions of websites in order of popularity, with an Alexa Rank of 1 being the most popular. Alexa Rank reveals how a website is doing relative to all other sites, which makes it a great KPI for benchmarking and competitive analysis. Alexa rank is calculated using a proprietary methodology that combines a site’s estimated traffic and visitor engagement over the past three months. Traffic and engagement are estimated from the browsing behavior of people in our global panel, which is a sample of all Internet users.
