Google Page Rank depends on backinks. In this manner more backlinks your website have then the page rank is more and it is affected by rank of the page linked to you. Secondly, age of the site is considered if your site has more age then it is more trusted and favorable to Google. A website with many incoming links, plenty of pages, and several internal links to other pages with the website then all these are well considered by Google.

you need to continue adding good content to your sites and bookmark your blogs on do-follow bookmarking sites.

When you submit your website on high PR sites then PR of that site is also share with you so it is more important to submit your site on high PR web sites so you will get good page rank.
