Alexa, which is owned by Amazon, used to analyze traffics and track our site statistics.
Do you all know how it is calculated?
If not mistaken, the Alexa is calculated based on sample of website users who have downloaded the Alexa Toolbar.
On a recent day, I found that my Alexa Ranking is 360,000++(Increased from 4mil 3 months ago). The implications are very straightforward, if you are a heavy user on Alexa Toolbar, perform own browsing on your site and having those users visit your site then it will affect your Alexa’s ranking significantly.
From my personal analysis, most of the Alexa users are webmasters and online marketers.
Generate NOT FAIR result
The Alexa Toolbar works only with the Internet Explorer and Mozilla Firefox browser. Other browsers will be undercounted. For instance, the AOL/Netscape browser is not supported, thus Alexa collects little traffic from AOL users.
The Alexa Toolbar works only on Windows OS. The traffic to any sites, which is other OS, will be undercounted.
Just my 0.02, if you need accurate ranking results; keep the Alexa browser off your own computer. Focus on Google Analytics, dont do comparison with other’s people ranking anymore!
