Introduction Google runs on a unique combination of advanced software and hardware . The speed you experience can be attributed in part to the efficiency of our search algorithm and partly to the thousands of low cost PC's we have networked together to create a super fast search engine.
The heart of our software is page rank™. And while we have dozens of engineers working to improve every aspect of Google on a daily basis, page rank continues to play a central role in many of our web search tools.
page rank Explained
PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an 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 considerably more than the sheer volume of votes, or links a page receives; for example, it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important." Using these and other factors.
Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank 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 dozens of aspects of the page's content to determine if it's a good match for your query.
IntegrityGoogle's complex automated methods make human tampering with our search results extremely difficult. And though we may run relevant ads above and next to our results, Google does not sell placement within the results themselves . A Google search provides an easy and effective way to find high-quality websites that contain information relevant to your search.
