How does Ranking.com gather the data?
Ranking.com tracks over 215,000 'Net surfers with our market research software (hundreds of participants are added daily) as they visit various websites during the previous month. Personally identifiable information is not collected, only generic information on the sites they are visiting is gathered with the exception of secure sites such as online banking or financial institutions.
How accurate are the Ranking.com results?
Our mission is to determine the overall "popularity" of Internet sites and how these sites compare to one another based on the behavior of our sample of users. Ranking.com achieves this by providing a statistical representation of a websites actual traffic, visit sessions and page views. The rankings provide webmasters and website owners with a helpful guide to understand which sites are the most visited (and in turn the most popular) on the Web. Ranking.com does not publish the actual traffic metrics to a website but rather the relative popularity ranking of domains in relation to all the websites visited by the sample group.
How often are the results updated?
Ranking statistics are updated monthly, usually on the fifteenth of each month. This may change periodically as the number of people using and promoting the service increases or as additional webmasters modify their listings.

Ranking.com also offers statistical
information on unique visitors,
visit sessions and page views:
Unique Users: "Unique
users" indicates the portion of all unique BrowserAccelerator
Toolbar users that visited a particular site in the last 12
months. Ranking.com expresses unique users as "number of
users per million". Take msn.com for example which lists
150,000 unique users per million. If you took a random sample of
one million Internet users, on average you would find that about
150,000 (15%) visited msn.com.
Visit Sessions: The number of "visit sessions" per million as indicated by Ranking.com is a measurement of the total number of 20-minute sessions from BrowserAccelerator Toolbar users to a particular site in the last 12 months. For example, if ebay.com has 196,000 visit sessions per million and you took a random sample of one million Internet users, on average you would find that 196,000 20-minute visit sessions were performed.
Page Views: The number of "page views" reported by Ranking.com indicate the number of pages viewed by BrowserAccelerator Toolbar users. The page views per million indicates the approximate number of pages that would be viewed by one million users in the last 12 months. For example, if yahoo.com has 4,600,000 page views, this means that if you took random samples of one million Internet users, you would on average find that all of them together viewed approximately 4.6 million pages on yahoo.com.
