Last post I spoke about Page Segmentation. Without recapping, one of the techniques I have found most successful is the placement of internal links in the main content body in the form of lists. This will give a solid boost to your site allowing individual deep pages to gain needed link and PR juice.
One site that does this quite well is How Stuff Works.
There will be more on Page Segmentation as this an on going discussion, so don’t worry I have a lot more to share.
