Not all websites implement our on-site analytics and publish the results. For these sites, we show estimated metrics based on traffic patterns across the web as a whole. 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. 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. Alexa Traffic Ranks The global and country traffic ranks show how popular a site is relative to other sites. • • 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.

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.

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. These metrics are updated monthly. Search Traffic The percentage of traffic, both free and paid, that come to this site from a search engine over the past 3 months, updated daily. The change number shows the difference versus the previous 3 month period. Top Keywords from Search Engines The table shows the top keywords that sent traffic to this site from major search engines over the past 6 months. The list is updated monthly.

Upstream Sites Upstream sites are sites that people visited just before they visited this site. Note that this list is not the same as referrals from upstream sites. There is not necessarily a link between the upstream site and this site.
