Alexa’s Traffic Ranks are based on the traffic data provided by Alexa’s global sample over a rolling 3 month period and are updated daily. An overall traffic ranking of “No data”, or “No rank” indicates that none of our sources show visits to the site in question during the past three months (as of our last update).
Please see How are Alexa’s traffic rankings determined? for more details on how our system works.
Note: If your site’s metrics are Certified you can choose to display directly measured Global and Country ranks for your site, even if there is not enough data from our sample to rank your site.
