Why my website PageRank is 0?

There are various reasons why a website’s PageRank is Zero, the least rank provided by Google is 0 and maximum is 10.

1. Website is relevantly new.
2. Check with your web hosting provider and see the statistical reports for downtime of your website. (If you have configured your website in webmaster tools in google, check for URL Not found - that will give you an idea, whether the site was down or that particular page does not exist)
3. Content is key - The choice of words (keywords) that are used in a site must be appropriate and detailed to what the site is all about.
4. Make sure you have META tags, META Keywords and META description in your HTML of any particular url of the web site.
5. Revist your web pages and update the content of the site as required.
6. It also depends on how many sites are linking to your site and their rank and as well the sites that you link outside from your web site. (inbound and outbound links)
7. Keyword stuffing, intentionally/unintentionally, i.e., keyword stuffing on META tags, in content for a specific word. Google penalizes if their algorithm thinks that you are misusing your site to cheat google crawler.
8. Website points to an external link that has been banned/penalized by Google/MSN/Yahoo/Any search engines.
