Some notes on page rank copied from my web site.
The precise algorithm for Google Page Rank is not published but it is known to be affected by:
- Original content
- Fresh, regularly updated content
- Themed sites i.e If your site is about marketing, pages devoted to crotchet will not help (and probably damage) your overall page rank
- Pages written for human readers and not designed to 'fool' the search engines
- Size of site - number of pages
- Number and quality of incoming links
- From similarly themed sites
- From sites with high page rank
- From sites with high traffic
- Important Sites with irrelevant links may be punished. Concentrate on quality of link, not quantity
- Number of outgoing links
- Internal links within your site
While the details of google page rank may not be completely known, it is very clear that the single most important thing in increasing the google page rank of your pages and site is down to the number and quality of the incoming links.
In highly competitive areas the page rank leaders have 100s of incoming links. If you operate in a less competitive niche you may be able to achieve a decent page rank with a few, good quality, incoming links.
Hope this helps.
