I guess most of you know that domains with pagerank are evaluated from a pagerank from 0-10 where 0 is the lowest and 10 is the highest. Even though many of you are trying your hardest to get your domains a higher pagerank, I doubt if any of you know what the corresponding points are for each pagerank? To get a PR1 (pagerank of 1) you need 8 points, but to progress to PR2 you need 64 points and 512 points for PR3 all the way up to the 1.073.741.824 points you need for a PR10 which is the highest. I think you should notice that this means that it becomes increasingly difficult to get a higher pagerank, the higher pagerank you already have. I can understand that this might be frustrating to you, but at least you know why the higher pageranks are really hard to come by.
