How is website ranked on Alexa Rank?

  • The traffic rank is based on three months of aggregated historical traffic data from millions of Alexa Toolbar users and is a combined measure of page views and users (reach).
  • As a first step, Alexa computes the reach and number of page views for all sites on the Web on a daily basis.
  • The main Alexa traffic rank is based on the geometric mean of these two quantities averaged over time (so that the rank of a site reflects both the number of users who visit that site as well as the no of page views.
  • The above is the logic to calculate the rank. But here are few notes that are important to read, before using alexa rank.
  • The data is more accurate given the greater sample source, but for lower ranking sites of 100,000+ the accuracy can be dubious.
  • Alexa’s traffic estimates and ranks are based on the browsing behavior of people in our global data panel which is a sample of all internet users. This means it is not calculated from all users but a sample size.
  • Alexa’s Traffic Ranks are for domains only and do not provide separate rankings for subpages within a domain. In contrast, google ranks each page to decide it's search results position.
