A FEW WORDS ABOUT PAGERANK
Google Technology - http://www.google.com/technology
"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 ... 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." |
