Are internal links, sub domains and other mirror urls useful in PR?

Sub Domains and Internal links

[jamaican]

My website is currently under construction and we have completed approximately 450 pages of what we believe to be valid content.

Some pages are www.****x.com/contentpage with links back to about 200 of the pages within the site. Are these useful.

Also if I create contentpage.xxxx.com as a sub domain with the same content and 200 links does that also count as another link.

Also we have the .com,.org,.net & .us for the site and we are going to mirror the site in each one of these URLs and run links back to the primary site and index page.

Also we have hyphnated all urls i.e www.xx-xx.com and created a backward link to the primary site as well.

What impact will this have as a link builder all will be text links anchored.

Welcome to WebmasterWorld, jamaican!

It sounds like you're headed for multiple domains with duplicate content, and actually 200 links on each page is far too much.

Just to be clear, are you asking for reasons of how all search engines will deal with this, or primarily how it will impact Google indexing and PR?

Thanks for the quick response marcia actually my main interest is how google will view this we can cut down on the links but we have a store and other category listings on the left and right hand side of the page in scrolling style, plus the regular info on top and on the bottom of the site.

So yes mainly how google will view it with 449 pages linking too the major index or home page plus approximately 23 other URLs all with the same content, approximately 400 subdomains for all 23 URLs all linking back to the major index or home page for the primary site.
