Google searches more sites more quickly, delivering the most relevant results.
Introduction

Google runs on a unique combination of advanced hardware and software. 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've networked together to create a superfast search engine.

The heart of our software is PageRank™, a system for ranking web pages developed by our founders Larry Page and Sergey Brin at Stanford University. And while we have dozens of engineers working to improve every aspect of Google on a daily basis, PageRank continues to play a central role in many of our web search tools.

PageRank 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, Google provides its views on pages' relative importance.

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 (and the content of the pages linking to it) to determine if it's a good match for your query.

Integrity
Google'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 (i.e., no one can buy a particular or higher placement). A Google search provides an easy and effective way to find high-quality websites that contain information relevant to your search.

pagerank的解释

下一页依靠独特的民主性质的网站利用其庞大的连接结构作为一个指标，个别页的价值。在本质上，谷歌诠释一个链接页，从一至二页为一票，由一个页，页乙，但谷歌来看相当多数量的选票，或链接页面领取;举例来说，它也分析页面投下选票。投票页面都是自己的"重要"重量更重，并有助于使其他页"重要" 。使用这些和其他一些因素，谷歌提供意见页的相对重要性。

当然，重要的网页意味着什么，你如果不匹配你的查询。因此，结合谷歌pagerank的精密文本匹配技术寻找网页都是重要的和相关的搜索。谷歌远远超出多少倍的任期出现一个页面，并探讨几十方面网页的内容（以及内容页连接） ，以确定是否是一个很好的匹配你的查询。
