there is no fast way and easy way to get your PR increased.
patience and effort should always be done.
backlinking is just the start, but you also have to consider making sure the content on your website are unique.
those are things that makes a website known and increase its exposure because of the originality that the website offers.
if you are after creating money blogs then try googling for increasing backlinks the not so good ways. :eye:
or if you are after increasing your blog in for a long term in a good and quality way then you have to go into sites where experts talk without dirt included. :lol:
