Larry and Sergey, two Stanford students with a passion for mathematics, had 25 years when they founded Google in September 1998. Shortly after founding the company, for lack of necessary funds to purchase new PCs and other equipment, tried to sell it for a million dollars to several financial companies, as well as direct competitors such as Alta Vista and Yahoo, getting only of waste. Although all agree that the innovative method developed by two students for their search engine with the most relevant results than its competitors, did not consider that the company was worth so much. Following these rejections, Larry and Sergey were forced to abandon Stanford University to devote himself to their company and they believed strongly in the project: to help Internet users find information more easily.
But what did (and what it has) so innovative Google over other search engines, some of which (Alta Vista and Yahoo) dominated the market at that time?
Larry and Sergey had the ball only for mathematics but also challenges for the “impossible” or that were considered impossible by many others.
Their mission was impossible to find a way to catalog all the information on the Internet and make them readily and easily available to everyone. And of course do it better than it already did Yahoo, Alta Vista, Info seek and other engines.
When they founded Google does not put the problem of gain, just wanted to solve a problem felt by them and their colleagues at the university: the difficulty in finding information easily found in nearly one billion pages on the Internet (today have become more than 8 billion).
The Page Rank :-
The most innovative was surely the invention of the “Page Rank”. The page rank is a method to determine the “importance” of a web page. While existing engines, for indexing and positioning of the Web sites in their database, they simply count the occurrences in the text of pages, words searched for by users, and then showed the top websites are not always relevant to the desired information, Page and Brin had the idea not only to verify and count the repetitions of words but also the links that were provided by other sites and that pointed to a specific page. Their reasoning was simple: if a site is mentioned and recommended by many other means that has interesting content and therefore it is right to show it before others.
In fact, the method adopted by the two students to calculate the Page Rank is much more complex and articulated, not simply to count the links, but also takes into account the “quality” of the content and importance of the sites from which the link. For example, if the site or recommend the Microsoft mentions my site, buy the same in the eyes of Google worth more than a competitor’s site recommended by an unknown company, and therefore will have a Page Rank higher than the competitor.
There are other factors that contribute to the Page Rank as the length of the site, the number of visitors, etc. .. I think nobody knows them all, even if you have already written thousands of articles and books on the “secrets of Google’s Page Rank.”
What matters is that users, using Google, you realize that it was easier and took less time to find the desired information, and therefore abandoned the other engines and advised friends and acquaintances to do likewise.
The explosive growth of Google has occurred mainly through “word of mouth”, the company has never advertised. It ‘s probably the only company in the world does not need it.
