Google PageRank (PR) defined an algorithm created by Google founders Larry Page and Sergey Brin are working to determine how important or how popular a site in cyberspace. How is the formula that the page rank algorithm?

Algorithm of page rank is calculated with the formula as below:

Algorithm PR (A) = (1-d) + d [(PR (T1) / C (T1)) + ... + (PR (Mr.) / C (Mr)]

The formula for other algorithms, PR (A) = (1-d) / N + d [(PR (T1) / C (T1)) + ...

+ (PR (Mr.) / C (Mr)]

* PR (A) is the PageRank page A
* PR (T1) is the PageRank of page T1 refers to page A
* C (T1) is the number of outgoing links (outbound links) on page T1
* D is a damping factor which can be between 0 and 1.
* N is the total number of web pages indexed by Google.

From this formula the page rank algorithm, the effect is page rank pages that refer to page A and the number of links. The explanation is as follows:

* A page will be considered important (has a high page rank) if other pages have a link to that page.
* A page will also become increasingly important if other pages rank (pagerank) high refers to the page.
* Also, in every page will be inbound links (incoming links) and outbound links (out links) of each web page.

Therefore, the calculation of page rank is recursive (repetitive) of thousands, millions even billions of web pages. A process that is very large and complex. Need not be confused with the process of calculating page rank, Google itself is counted.

PageRank scale

After knowing the definition of page rank, we also have to know scale of page rank. Page rank is calculated on a scale of 1-10. A site that has a page rank 9 will be ranked first in Google’s search listings than sites that have page rank 8 and then onwards are smaller.

So, page rank is made Google algorithm to determine how important or popular a site (blog or website). Another function of this page rank is to sort the site in Google search list.
