PageRank technology

PageRank technology

PageRank technology involves the use of an equation which comprises of millions of

variables and terms and determines a factual measurement of the significance of web

pages and is calculated by solving an equation of 500 million variables and more than 3

billion terms. Unlike some other search engines, Google does not calculate links but

utilizes the extensive link structure of the web as an organizational tool. When the link to

a Page, lets say Page B is clicked from a Page A, then that click is attributed as a vote

towards Page B on behalf of Page A.

Quintessentially, Google calculates the importance of a page by the number of such

‘votes’ it receives. Not only that, Google also assesses the importance of the pages that

are involved in the voting process. Consequently, pages that are themselves ahead in

ranking and are important in that way also help to make other pages important. One

thing to note here is that Google’s technology does not involve human intervention in

anyway and uses the inherent intelligence of the internet and its resources to determine

the ranking and importance of any page.

Hypertext-Matching Analysis: Unlike its conventional counterparts, Google is a search

engine which is hypertext-based. This means that it analyzes all the content on each web

page and factors in fonts, subdivisions, and the exact positions of all terms on the page.

Not only that, Google also evaluates the content of its nearest web pages. This policy of

not disregarding any subject matter pays off in the end and enables Google to return

results that are closest to user queries.
