What is Alexa Rank?

Many bloggers including myself are curious about Alexa Rank. I often visit my friend’s blogs or webs, and I always find that they put alexa page rank in their websites or blogs. At first I have no idea about the importance of this Alexa Rank. After asking some questions to my friends, then I know a bit about it and start finding information from the king of searching, Mr. Google hahaha.

What is actually Alexa Rank?

To know more about the definition of Alexa Rank and how it works, I take some explanation directly from the official web of Alexa, and here it is :

"The traffic rank is based on three months of aggregated historical traffic data from millions of Alexa Toolbar users and data obtained from other, diverse traffic data sources, and is a combined measure of page views and users (reach). As a first step, Alexa computes the reach and number of page views for all sites on the Web on a daily basis. The main Alexa traffic rank is based on a value derived from these two quantities averaged over time (so that the rank of a site reflects both the number of users who visit that site as well as the number of pages on the site viewed by those users). The three-month change is determined by comparing the site's current rank with its rank from three months ago. For example, on July 1, the three-month change would show the difference between the rank based on traffic during the first quarter of the year and the rank based on traffic during the second quarter".

So from the explanation above, we know how alexa works to page rank our Webs or blogs.
