PageRank
PageRank explained by Google:
Google interprets a link on page A going to
page B as a vote -- by page A, for page B.
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.
