“PR”是PageRank的简写，也就是“网页等级”的意思，以10分为满分。PageRank作为Google的网页评价标准，在过去相当长的地段时期内曾经是搜索结果排序的唯一参照物。许许多多安装了Google Toolbar的用户也倾向于通过简单明了的PR图示判断所访问页面的重要性，或者可以说是“权威性”。
我倒是知道苹果APPLE的网站的GOOGLE PR值是10，而他们的成就却让你吐舌~你看看下面的截图，附带了10到1的各个页面的连接！

Google, the most popular search engine worldwide, provides web surfers with an easy-to-use guide to the Internet, with web and image searches, language translation, and a range of features that make web navigation simple enough for even the novice user. What many users don't realize is that the deceptively simple components that make Google so easy to use are the same features that generously unlock security flaws for the malicious hacker. Vulnerabilities in website security can be discovered through Google hacking, techniques applied to the search engine by computer criminals, identity thieves, and even terrorists to uncover secure information. This book beats Google hackers to the punch, equipping web administrators with penetration testing applications to ensure their site is invulnerable to a hacker's search.
Penetration Testing with Google Hacks explores the explosive growth of a technique known as "Google Hacking." When the modern security landscape includes such heady topics as "blind SQL injection" and "integer overflows," it's refreshing to see such a deceptively simple tool bent to achieve such amazing results; this is hacking in the purest sense of the word. Readers will learn how to torque Google to detect SQL injection points and login portals, execute port scans and CGI scans, fingerprint web servers, locate incredible information caches such as firewall and IDS logs, password databases, SQL dumps and much more - all without sending a single packet to the target! Borrowing the techniques pioneered by malicious "Google hackers," this talk aims to show security practitioners how to properly protect clients from this often overlooked and dangerous form of information leakage.
