I'm no see expert but I've been doing a little testing on some of my sites since the penguin update and I have noticed that there are lots on inner pages ranking and lots of searches returning multiple pages in the SERPS
It seems that Google has changed the value of a link, a site that had say 300 links from with no teir 2's is not a powerful as maybe a site with 100 links and 2 or 3 teirs pointing at them
This seems to be the same with the pages within your own site, I send links to an inner pages and the pages that have been linked to from this page start to show up in the SERPS for my keywords too
That might be why bigger site with lots of inner links get multiple pages for one search
I recovered a site (very low comp) by building bookmarks 4 tiers high with only about 30 pointing at my home page
Would love to see if anyone else is seeing the same results!!
