Certified Site Metrics are metrics that are directly-measured from the website instead of estimated.The website owner has installed an Alexa Certify Code on the pages of their site and chosen to show the metrics publicly.
If a site has Certified Metrics instead of estimated, that means its owner has installed code allowing us to directly measure their traffic.
These metrics have a greater level of accuracy, no matter what the ranking.
Learn more about Alexa's Data Unique Visitors and Pageviews The number of people who visit this site and the number of pages they view.
Site owners who install the Alexa Certify Code on their website can choose to display their Certified Metrics, such as Monthly Unique Visitors and Pageviews, if they wish.
We identify these patterns by looking at the activity of millions of web users throughout the world, and using data normalization to correct for any biases.
The more traffic a site gets, the more data we have to calculate estimated metrics.
Estimates are more reliable the closer a site is to being ranked #1.
Global traffic ranks of 100,000+ are subject to large fluctuations and should be considered rough estimates.
For other sites, we display the estimated number of unique visitors from up to 6 countries, when sufficient data is available (Advanced plans only).
Audience Geography The audience geography data describes where visitors to this site over the past month are located, and how the site is ranked in popular countries. Engagement metrics help you understand how interested a site's visitors are with the site's content.
If a country is not listed, it is because Alexa does not have enough data for this site to rank/measure the site's popularity among that country's online population. The metrics are updated daily based on the trailing 3 months.
