I can try but you will prolly be less confused if you follow the link at the end of this post.

First have you ever checked page rank on a sites index and compared,
http://www.domain.com with
http://domain.com and found they have different page ranks? Afterall it is the same page. The search engines see them differently tho. If for example you have ibl's (inbound links) coming into your site using http:
www.domain.com and you use relative linking within your site, you are splitting your page rank. You can boost the pr by using absolute linking if the ibl's are using the full url (
http://www.domain.com)
I have figured out it helps to have almost every page with a link pointing back to the index using absolute linking. This way you are telling the bots which is the most important page on the site and not splitting your page rank between http:// and
http://www.
Just so I don't confuse you anymore than I already have these links will help.

There are a bunch of good articles on this site, (
http://www.webworkshop.net/) I especially like the ones about doorway pages. After reading them, I really have to wonder why link list owners do not like pics on html pages. They could boost the pr a bit to your index which is linked to them.
