Alexa.com principle of ranking

The so-called entry-level site, is the number of visits between 500 to 5000 of the site, in general, to enter this level of the site needs to understand the Alexa ranking principle, the specific situation please www.alexa.com study, but this monitoring software as the next problem, must understand
(a) Alexa and Amazon's own website traffic statistics are high
b) Alexa toolbar can only be embedded in IE browser, so the use of other browsers (such as Aol/netscape) of users can not be counted
c) Alexa toolbar only for Windows operating system, the use of other operating system users can not be counted
(d) The use rate of Alexa toolbar varies across the globe, influenced by geographical, linguistic and other geographical and cultural factors. For example: South Korea Internet penetration rate is high, the country uses the Alexa toolbar The person also more, therefore causes the South Korea website rank before the partial
(e) Alexa's automated search program sometimes fails to identify whether different servers point to the same content (contents) of the Web site, which may also result in inaccurate domain names and home pages
F Some of the more secure site traffic can not be counted
G The traffic is too small site statistics may be inaccurate, the overall ranking on the front (the greater the flow) of the site statistics will be more reliable. Generally speaking, the monthly visit volume below 1000 or ranked 100,000 after the site statistics are inaccurate

Understand the Alexa ranking principle, we have to use a more familiar with the medium site to do comparison:
The following is the statistics on the number of visits per million people in Alexa, which are available in the first quarter of 2003:
Peking University 370 Tsinghua University 200 Zhejiang Universities 105 Nanjing University 90 Shandong University 85 Shanghai Jiaotong University 78 Wuhan Universities 78 Zhongshan University 74 Fudan University 67 China University of Science and Technology 50
In other words, according to the Alexa principle, when there are 100 million Internet users in the world, the number of visits per million is about 1% of the actual population, which means that about 37000 people visit the website of Beijing University every day, which is feasible.
According to our long-term monitoring of Shanghai Power Elephant Company, the company's visit has been maintained at about 1000 to 1400 people, the world ranking between 28000 to 39000, the number of visits to 15 to 18 people, from our installation in the company's additional set of routing statistics, Can be seen some differences, but basically do not return to too much difference.
