Just to add a comment on page rank, from what I've heard that is a actually a very small contributor to the overall google algorithm. That is - at least in the way it was originally conceived by Larry Page - PageRank is now only a minuscule tuner amongst 100's of other tuners in the overall search algorithm now, but because it was the first and core part of the google algorithm, people still continue to assume it is the predominant one.
