One of my domain registered on 23-jan-2007 is now PR 5, and 22 domains registered on 27-Mar-2007 are PR
From PR0 to PR4 is not a big achievement. Most sites can achieve this with a solid link building campaign. Congrats nonetheless.
I get PR 5 directly from PR 0 within 3 months without any solid link building campaign. All you need is some quality content, people love to link back quality stuff.
Though many people discard the importance of PR --its an important aspect of SERPs as is explained in the Google's webmasters guide. PR is dynamic --changing everyday--but that we can not see. We can only see PR of a site on the toolbar for a particular time when the SNAPSHOT on the site is taken. We see that static stat for about 3 months till the next PR export to toolbars ( not PR update as most people like to call it). As PR changes almost all the time --due to Google bots finding some backlinks and not finding other -- So we also see big changes in SERPs too--going up and down. Every one knows --good relevant backlinks are they key to achieve good SERPs --but how does one get good PR? Its the same Matric. So some people discarding PR and saying PR does not help SERPs are not saying the entire thruth. One has to just understand how the bots work ( Googl's Webmasters Guide --How Google Technology Works is a better indication than articles by SEO experts)--and they know --what they have to do to get good SERPs. Tnx.
Ah the age old battle of is PR important or not important. Glad to see that this one will not die. Congrats on your site. Unique visitors are probably more important
mine is also updated to PR4 (i started January 2007) but i have only 500 uniques visitor, your uniques are triple of mine, how come... i think Google loves brazilian more than others
