how is your internal navigation structure?

how much unique content is on each page as a percentage of the total content on the page?

if you have lots of boilerplate that is duplicated on 10's of thousands of page or insufficient internal navigation/inbound links, a sitemap won't do much for you with crawling or indexing.
