Google PageRank: What do we know about it?

  • Each Page Rank level is progressively harder to reach. “PageRank is logarithmic in its calculation. In the same way that the earthquake Richter scale is exponential in calculation, so too is the mathematics behind Google PageRank. It takes one step to move from a PR0 to a PR1, it takes a few more steps to PR3, it takes even more steps to PR4, and many more steps again to PR5, and so one.” [Google Page Rank FAQ]
