PR and Directory Depth

[bigsefreak]

I am little confused. I am having a web site about songs and each song has its own page with detailed info about the song. Our current directory structure is

www.domain.com/songs/1.html, www.domin.com/songs/2.html... www.domain.com/songs/n.html (n > 15,000)

We are currently having PR6 and expecting PR7 (or hopefully more, with increasing inbound links from other good sites) in near future. Now my main concern is, should be build all the detailed pages in songs/ dir or within root directory. Because I read somewhere that, in normal cases, PR goes down by 1 with every directory level, and I believe it would make a significant difference if PR of all the detailed pages would be +1.

Can you can help me with the issue and tell me if I should undertake the headache of updating all the detailed pages?

Thanks for the help.

Not so, it depends on how many clicks away from the source of the high PR page it is.

One click from the homepage to www.domain.com/1.html
is the same as one click from the homepage to www.domain.com/songs/1.html

IF you had a link from www.domain.com only to www.domain.com/songs.html and all the links went from songs.html to the directory pages without them being linked to from the homepage, then they'd be 2 clicks away. But your songs pages are also passing Page Rank to each other, as well as back to the page they're linked to from.

It isn't automatic to lose PR by a page being in a directory, it's not structure-dependent, it's based on the numerical value of the link itself, the value of the link passing on PR from a link on one page to another.
