How does PageRank work?

PageRank is passed through links. Each page only has so much PageRank which it can pass to other web documents. A dampening factor (approximately 85%) is set to allow the current pages PageRank to propagate through the rest of the web, while preventing all we pages from being ranked at a 10 or a 0.

The off going PageRank is split up between all links on that page (including links to other pages within that site). Therefore a PR 5 link on a page with 10 links is worth way more than a couple PR 5 link on a page with 100 links. One PR 8 link may be worth more than a thousand PR 3 links.

The value of any given link is hard to determine exactly. Generally though less links on a page means that more of that pages PageRank will be parsed out to your site. Also the higher the PageRank of a page the more PageRank it can pass on to other pages.

A page does not lose PageRank by linking out to other sites (unless it links out to penalized sites), it just has less PageRank to share amongst the other documents it is linking to.
