The size between 1 and 10 is logarithmic, that’s, the distinction between 5 and 6 could also be equal to the distinction between 0-5, and the gap between 9 and 10 could for instance be as giant as 0-9 (for instance ).
There are just a few hundred pages on the web that has a worth of 10 as Toolbar PageRank. To succeed in as much as four doesn’t appear to be that troublesome. In the event you attain 5 you might have come a good distance whereas the highway to six, nevertheless is lengthy and exhausting.
