What is alexa Ranking.

In simple terms, Alexa Traffic Rank is a rough measure of a website's popularity, compared with all of the other sites on the internet, taking into account both the number of visitors and the number of pages viewed on each visit.






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.
Alexa’s Traffic Ranks are based on the traffic data provided by users in Alexa’s global data panel over a rolling 3 month period. Traffic Ranks are updated daily. A site’s ranking is based on a combined measure of Unique Visitors and Pageviews. Unique Visitors are determined by the number of unique Alexa users who visit a site on a given day. Pageviews are the total number of Alexa user URL requests for a site. However, multiple requests for the same URL on the same day by the same user are counted as a single Pageview. The site with the highest combination of unique visitors and pageviews is ranked #1. Additionally, we employ data normalization to correct for biases that may occur in our data.
If your site’s metrics are Certified you can display Global and Country ranks for your site based on Certified Site Metrics, instead of metrics estimated from our data panel.
Alexa’s Traffic Ranks are for top level domains only (e.g., domain.com). We do not provide separate rankings for subpages within a domain (e.g., http://www.domain.com/subpage.html ) or subdomains (e.g., subdomain.domain.com) unless we are able to automatically identify them as personal home pages or blogs, like those hosted on sites like Blogger (blogspot.com). If a site is identified as a personal home page or blog, it will have its own Traffic Rank, separate from its host domain.

There are limits to statistics based on the data available. Sites with relatively low measured traffic will not be accurately ranked by Alexa. We do not receive enough data from our sources to make rankings beyond 100,000 statistically meaningful. (However, on the flip side of that, the closer a site gets to #1, the more reliable its rank.) This means that, for example, the difference in traffic between a site ranked 1,000,000 and a site ranked 2,000,000 has low statistical significance. Sites ranked 100,000+ may be subject to large ranking swings due to the scarcity of data for those sites. It is not unusual for such sites to decline to “No data” Traffic Ranks, or to improve suddenly.
