Google PR (PageRank) updates are under way again, just a month after the last update. Typically updates occur every 3 months or so making this update a bit out of the ordinary.

PageRank Forumla = PR(A) = (1-d) + d(PR(t1)/C(t1) + … + PR(tn)/C(tn))

Page Rank is an often misunderstood and misinterpreted part of the many signals and components that make up the Google ranking algorithm like. To keep things complicated, read this primer. To keep things simple, PageRank uses a logarithmic scale and is based primarily on incoming links. In plain speak, this means that if PR were on a point scale and moving from PR1 to PR2 took “10 Points”, then moving moving from PR2 to PR3 might take “200 points” and moving from PR3 to PR4 might take “1500 Points” and moving from PR4 to PR5 might take “9500 points”. I think you get the idea, while my points system is just nonsense I’ve made up, the point is that each move upwards in PR becomes exponentially harder. What does PageRank mean to you? Well for starters, PageRank does not guarantee high search engine rankings. PR is more of a qualitative measure of a site, but does not translate into directly higher rankings, although there is no reason why a site with high PR shouldn’t rank well also. Well it’s perfectly normal to get excited as you watch your PR grow. The truth is that I’ve had sites that I’ve put no effort in building links to become PR4. While PR5 is definitely respectable, I think PR6 is a real accomplishment and requires a real sustained effort, most blogs will never become a PR6. At the end of the day you can NEVER go wrong focusing on publishing high quality content that others find useful. If you do, people will link to you, you will rank well and eventually your PR will follow. PR is a lagging indicator, so don’t put the horse in front of the cart!

One thing is for sure, over the last couple of years it seems to me that PR3 is the new PR4. In other words, PR ranking has become harder to achieve.
