PageRank Explained ... by Google

I realise this has probably been posted before, but it's still an interesting read:

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 PageRankâ„¢, 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 provide
the basis for all 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 more than the sheer volume of
votes, or links a page receives; 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."

Important, high-quality sites receive a higher PageRank, which Google
remembers each time it conducts a search. 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 all 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
results extremely difficult. And though we do 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 higher PageRank). A Google search is
an easy, honest and objective way to find high-quality websites with
information relevant to your search.
