Alexa's ranking rationale
Alexa's ranking is based on
Alexa (/) is a web site dedicated to world ranking of websites. Alexa every three
A new consolidated ranking of the website is published monthly。
Alexa's ranking is based on browsing -- that is, the number of user links (users reach) and the number of page views
Three-month accumulated weighted geometric averages. Although the weighting is undecided。
But at least:
one million users click on two sites equal in number, and whoever has a large page view is ahead
2 each user views two websites with the same number of pages, and whoever has a million hits is ahead
3 both parameters are equivalent to two websites, and they rank equally。
user links (users reach): " million user hits" means access to a particular particular internet
Number of persons on the website. This is expressed as a percentage of all internet users accessing a particular website. I. E., used
Household links = (number of visitors/total number of alexa users)* 100 per cent, with alexa per million people. Here
Yahoo, for example, if it has a 28% number of links, it's a million randomly drawn
Internet users, of whom 280,000 have access to yahoo。
Page viewes: " page views per user" refers to a specific website visited by the user
How many pages are there? Is the sum of the pages viewed by all users accessing the website. Pages viewed per user
The average is the average number of separate pages per person per day for all users accessing the website. Same person, same person
One day, multiple visits to the same page are recorded only once。

Alexa's ranking prerequisite
alexa based only on computers that have installed alexa plugins, use windows operating systems and use microsoft ie
Users visited do the statistics. Users who do not meet either of the above conditions are excluded from the statistical scope。
Alexa's ranking is based on average access and page link access per million installed alexa plugins。
Alexa is also being analysed according to ip regional sources, and the more widely dispersed the ip address areas visited, the more the ip addresses are located in the same location
The higher the ranking on the site, the higher the profile。
Alexa's ranking is also based on the repetitive basis of visiting ip, which is the number of daily ip visits to your website
The more you rank on your website, the more you visit the new ip, the more you may not get up。
when a secure or encrypted site is encountered, the alexa toolbar will be automatically closed, so those safety factors
High websites, alexa will not be able to search for them and rank them statistically。
