If you have a good site, got numbers of links to your site and want to improve your pr quicker, here is the way to do:
if you already pr 3 ( just for examble ) and you want to have pagerank 4, just try to find someone who has pagerank 4 ( the linkpage ) link to you, but if you have pr 5 and want to be pr6 or even 7 you may have to buy one revelant link ( 70% revelant is ok ) which is pr 6 or 7. note that you dont have to buy it for long time ( about 3 months only - depend on which site you buy from ). I think google will quicker make your pr that you expected if you doing things above.
and when you already have pr 6, you are popular already, and higher pagerank for you is just the time. No need to buy any expensive links anymore.
How about other opinions about this? I think there are plenty of newbie ( like me ) here find it useful?
good weekend, guys
