The Google Page Rank Algorithm

September 10, 2007      (Updated from our previous Nov. 2003 article)

It's no secret anymore that Google ranks as the number one defacto-standard in the field of major search engines. Today, Google accounts for more than 85 percent of all Internet searches on a daily basis. Google now has many versions running in many different countries, including China, Japan, the U.K., Hong-Kong and many others. Rank for Sales knows of many small and not so small businesses whose livelihood almost basically depends on Google bringing them new customers, day after day.

When the livelihood of an entire company depends on just one search engine, this tells you a lot about the success of Google. It also underlines the importance of any web site ranking high in Google. In order to develop an independant and objective ranking system that has integrity, is both fair to everyone and is efficient for all end users searching on a specific keyword or keyphrase, Google has developed the Page Rank (PR) Algorithm.

The Google Page Rank value relies on the uniquely democratic nature of the Internet by using its vast global link structure as a prime indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes read it, or links a page receives. It also analyzes the page that casts the vote. Votes cast by pages that are themselves important or are favorably viewed as "established firms" in the Web community weigh more heavily and help to make other pages look established too.

Established, high-quality sites receive a higher Page Rank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines Page Rank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query.

Google's complex, automated algorithm makes human tampering with their results extremely difficult. And altough Google does run relevant ads above and next to their results, Google does not sell placement within the results themselves (i.e., no one can buy a higher PageRank). A Google search is an easy, honest and objective way to find high-quality websites with information relevant to users searching specific products, services or information on a particular subject.
