As we all know that Google PR is dependent on the backward links of the website. To increase PR, many people do directory submission and link campaign to get more and more backward links from high PR pages. Yes, it is the good way to increase the Google PR, but if you want to get good PR and if your website is new, then first submit your website in various directories and create blogs linking to your websites and do blog posting and blog submission. It has been seen that the links from blogs have high weight as compared to links from other sites.
But do remember; never go for link spamming through blogs. It comes under black hat SEO and Google can ban your site.
So, if your website is new then blog submission is the best way to get high PR on its first PR update.
