With the Alexa Multiple Rank Checker, you can discover how Alexa ranks multiple websites. Alexa creates a traffic rank for websites based on data collected through its own toolbar. The Alexa toolbar is installed in thousands of Web browsers and has been used to gather useful data for many years. Site data from the toolbar, along with other private sources, is used to determine a site's overall worth.
Many advertisers and potential site buyers will consider a site's Alexa traffic rank for this reason. Use this helpful webmaster tool to check the Alexa traffic rank for multiple sites of your own or any sites you are considering for purchase or advertisement purposes.
