Have you noticed PR Updates, I have seen some blog posting and social media site updates that their PR increased, well for this blog it is still PR3, PR ( Page Rank )Â is only needed if you would like to sell links because most of the link buyers are PR hungry. They believed that PR is one of the big factors in SEO ( Search Engine Optimization ) , which I disagree.
So How important is page rank for you ? Do you notice increase in traffic after increase in Page Rank ?
