2 months to pr4 on a wordpress blog (I love wordpress)., For our company site we went to pr 5 in 5 months and to pr 6 in 1 month (in the recent update, though its not remaining stable)
took me about 3 updates to hit PR6 on a site. a couple of sites who i aint working much on still languishing at PR5 after 3 updates.
We just got to a PR7 after launching about a year and a half ago...we were a 6 forever. We haven't done a lot to try to bump up our ranking...a couple of listing on Digg, Lifehacker, etc. probably didn't hurt.
Well, I spent today submitting to 27 blog directories with PR5 and above, so hopefully that will push me up a little. For the rest of the month, I'm going to work on getting more backlinks from similar niche blogs, since there are plenty around with PR4-6. Keep 'em coming - anyone got a PR9 or.. dare I say it... PR10?
I took me about 3 or 4 months to get about 6 sites to this : 2x PR4 sites 2x PR2 sites 1 PR3 site 1 PR1 site I`m selling link for those sites here. I mention that because I think the best and easiest way to get your PR up is to have backlinks from high PR sites.
I have one site that is almost 7 years old and is still PR4, one site is under a year old and is PR5.
It took me several cycles with Google to climb the PR ladder. I am at a PR 3 and climbing. However, I started with a brand new domain name and content.
