7. You need backlinks. Backlink is a link from other page pointing to your page. More backlinks you have and higher PR they have, better chance for you to have high PR on your page.
You will hear two more fat lies about PageRank:
- Some new pages (for example freshly opened blogs) can get PR higher than 0 even without backlinks. You can blame so called Google dance for that.
This is not true. When you publish new blog it will be probably shown somewhere. If we look for instance at wordpress.com, your blog can be shown after publishing for some time on first page and if it is indexed by bots just at the right time in the right place, it can get PR 5 or some similar undeserved number just on that trivial fact.
- You can get higher PR by adding fresh content, deleting duplicated content and checking your texts for typos.
This is just not the case either. PageRank is dependent on backlinks only. I have seen numerous pages breaking those rules, full of dead links and typos, without fresh content for years and so on, but still having PR 5 or 6. They only had powerful backlinks and this is it.
8. Nobody (I believe that includes Larry Page) can say for sure, how many links with certain authority you need to achieve certain PageRank on your page. Experiments show you need about 18 backlinks with PR 3 to have PR 3 on your site. You need about 5 backlinks from page with PR 4 or only 1 backlink from page with PR 5 to achieve the same authority.
9. Things complicate further because the strength of every backlink (what is related to passing authority from one page to another) is dependent of the number of backlinks on page from where backlink comes to your site. In web directories you can get easy backlinks but in company of thousand backlinks the authority you get is insignificant.
