Google measures the value of a webiste based on several factors that rely on constant data from the links and websites across the Internet to assertain. There are many techniques we use to improve Page Rank (PR) that google will see as possitive steps towards achieving status online. Here are a few of the things google looks for:

1. The number of external websites linking to the pages on your website.
2. The average of the actual page rank assigned to each internal web page on your site.
3. Whether or not you are linking to external sites with "link farms" present, or too many links!
4. The number of times a website links to your site without reciprocation. One-way links.
5. The relevency of the external links pointing to your site to your site's content.
6. How long your website has been online and what has been the general theme.
7. How long your domain name is registered for, i.e. 1 year, 2 years, 5 years, or even 10 years.
8. How long it has taken your site to achieve any and all inbound website links.
