Google considers many things before giving PR to a site....those things are quality back links, unique posts, quality contents, decent traffics etc...

It's totally depends upon site content and incoming links for your site...

Guest Posting on high traffic or high PR blogs is one of the important factor to acquire high PR....If you rae interested in it...You may consider to let me know....It will be great to guest post on my blog if your target audiences are from India or you want to target Indian audiences....

It's totally depend upon your site content..

It depend on your website formatting and Content.

There are so many factors, which can affect the present page ranking and one of the best one, deals with inbound links. These help in creating best links.

Google checks your on page and off page both for giving Page Rank but nowadays I think Google has stopped updating Page Rank.

PR is a link analysis algorithm used by Google to assign a value of 0-10.PR totally depends on your reference links
