Keep on building quality backlink.
And ensure the link is dofollow since nofollow would not help on your PR

Dear D.

It is very easy to promote your blogs and get the higher google page rank. The easiest way to do this is to build the quality one way in links or back links.

In order to do this, You should find the free website directories (search engine seo friendly web directories) appropriate to your business and/or blogs. Please make sure, they are human edited web directories and contain the quality websites.

Please start your submissions, the more the higher. While submitting, please be very specific to the submissions, for instance while choosing the Title for your site/blog, please write the blog name without the .com / .net / or any other extensions you use.

Write the specific description about your blog e.g. provides information about sports, or provides information about worldwideweb, website tools etc. Do not write the same over and over again. This may be considered spam and you may not be approved the the directory adminstrator.

Submit the quality press releases and articles appropriate to your blog, and again be very specific to the titles, description.

Join Forums, appropriate and related to your blog, discuess the things in there and then later on when you are a mature user, leave the links, this will help you get more traffic and backlinks, and will lead to obtain the pieces of PR from there.

Particepate in the DO follow blogs and make sense while you ask or answer something.

Tweak your meta tags, description and content atleast once a month.

Please note, do not submit more than 25 directories a day, 3 articles and press releases a day.

Please particepate in the social bookmarking sites and submit your website there.

You are almost done…. The quality submissions will help you obtain higher PR, quality traffic to your website, maximum hits and higher search engine rankings.

Hope this helps.
