what the pr mean to my site?

Pls tell me how to make pr to my site and what factors do i have ?

You need to do some thorough SEO Link Building to have a higher PR on your site.  ;)

Write an article related to your site and submit it in different article directories. It works.

Link building is the key, that's all

And your website content should be unique. And your site very well optimize. And share link with high page ranked sites

I agree with two comments posted here - generate informative, niche-focused, keyword-targeted, easy to scan articles (you can job out the writing if you want), submit these to article directories to generate back links, and take part in leaving comments in high page ranked sites that allow leaving links to your site. Make sure many of the anchor text you use are also the keywords you're targeting. That's how you fish for enough traffic to your site to get its page rank increased.

Just try to build some quality backlinks and it will help you to find your desired results.

Just remember that PR have a very little or even not at all meaning if you are trying to attracts many visitors. There are many websites with 5PR and only dozens visitors a day. The better measurement tool is alexa ranking - but it is not perfect too.

On page really matters to attain a good PR and link building plays the backbone role in that purpose.

you should just link build that is the way to go

PR means Page Rank, created by Larry Page of Google and is one of over 200 indicators to the Google serps.  What it means is you have a certain amount of inbound links pointing to your site.
