How does a page move higher from one PageRank level to the next?
• Page Rank is represented numerically from a low of PR0 to a rarely achieved high of PR10. PageRank is not a series of equal steps. It 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. Each level is progressively harder to reach.
