1. Your site should be updated regularly
2. Blogs are rated highly
3. Other sites that link to your site increase your page rank
4. Links to other sites (preferably active ones) increases your page rank
5. Keyword rich content increases your page rank. For example, if you have a site about doorknobs, the term "doorknobs" and related words should be used in the text throughout the site, as well as in the meta tags (although putting it in the tags is not as important as it once was).
