Alexa

Alexa as Amazon.com subsidiary in California, provides information about the level of user visits a website via its web site, alexa.com. Alexa was founded in 1996 by Brewster Kahle and Bruce Gilliat. Basic estimates obtained for a web site from a large number of unique users who accessed the website for current Alexa algorithm program.

System:
1.    The lower the Alexa ranking of the value of a website, the more crowded the user visits the site website.
2.    Ranking of a website based on the measurement of reach and pageviews. Reach is measured by looking at the number of global Internet users who visit the site while Pageviews are the total number of Alexa users are requesting the URL of a site. Request URL repeat of one user on the same day will be counted as a single pageview.
3.    There is also a saying that no matter how long visitors stay and explore your website, also included in the calculation Alexa.
4.    Alexa calculations by default by 3 months, but included also display calculations 7 days and 1 month.
5.    Alexa rank only on the primary domain only (eg http://http://luciusparker.blogspot.com/). So all subdomains and other pages keep up the value of the primary domain only. However, as an exception, that this does not apply to users of wordpress blog (http://xxx.wordpress.com) and blogspot (http://xxx.blogspot.com), that at first, the value of alexa still follow the main domain, but as time goes by, the value of the specific alexa for each subdomain. Maybe there are more than 2 provides additional blog.



What is meant by Program algorithm Alexa:

1. Add-on Firefox: Sparky Alexa Toolbar. This program applies to the Mozilla Firefox browser only. Performance among others currently accessible web site address, then Alexa was active program accessing the website and occurs calculations.
I do not know the exact promotion strategy between Firefox and Alexa about why the program is only available for Firefox only.

2. Script Alexa widget on the sidebar of your web site. According to some blogs that I read, is a powerful way, because every user who accesses your website, Alexa program runs automatically, although the user's browser is not there Sparky Alexa Toolbar.
 
Why should we try to increase it:
1. As the prestige / prestige that your website is visited.
2. Benchmark for users who want to put banner / ad on your website.

Disadvantages:
1. Since the calculation of the total program relies Alexa algorithm to be active, so although the site your website gets many visits from the user, but if most users do not include Alexa program, then your website visitors by Alexa ignored.
2. Calculations based on how many IP users (unique) in 1 day. So although there is 1 user accessing 100x as much in one day though, still considered 1x visits.

Advantages:
Dependence with Alexa algorithm program, then we can manipulate and strive to improve the Alexa ranking.
