Getting a good page rank depends on many factors. Firstly onsite SEO, you need good quality content, nice keyword density normally around 3% and most importantly make sure you're offering your target audience something valuable, you'll get organic backlinks this way.

Offsite seo will involve you getting high quality backlinks from relevant sources, high page rank backlinks will help as well. You'll want a diverse link profile using lots of different platforms.

These days social signals also have an impact on SEO and PR, so don't forget those. Make sure you have a twitter, fb, google + etc for your site.
