I haven't payed attention to my computer support site in 2 months which i had written only 10 articles, none of which i have submitted to directories. Well it went from PR0 to PR5 over the past 2 months! It has 27 google links. Alot of which im ranked #1-#10 with the average being #3 out of 5Mil-80Mil results. I'm looking at my stats and im getting alot of SE traffic to certain articles from the big G... Funny thing is its not very well optimized (need to rework the joomla templates), and doesn't use SEF URLs. haha looks like I should start working on it after all! On top of that I haven't even thrown in any adsense... Im debating if i should put it on there or not. Anyways... is it difficult to go from PR0-PR5 as fast as my site went? If i add more optimized unique articles should it be easy to go to 6-7?
One of my sites started out as a PR5 from one inbound link..the next update it dropped down to a 4. I added a bunch of links to $ generating sites of mine and the index page dropped down to a 3...but the interior pages are still 4's. I am interested to see where yours go's. Keep us updated.
No, I don't think a PR 5 is hard to do. And, no. PR 6 takes some work, but is doable. It's much harder to get into the 7 - 8 PR range (in my observations, at least ...)
