Just noticed that few days ago Google made new PR update. A lot of people have been waiting that for ages. I had some luck, few of my PR4 sites climbed up to PR5, but my only PR6 site dropped down to PR5.
Everyone knows that PR and ranking high doesnt come hand in hand anymore.
But high PR is still good for selling links. And of course good backlinks always means higher rankings and traffic.
So, go build your backlinks now, next update will be at unknown time, most likely in around 3-4 months.
