Google Marking most links as Excluded (Canonical Page). What to do?

SEO Gurus and fellows,

I have an aggregator website with server side loading. Because of the front end, net content changes relatively less per page.

Google is Excluding all the pages, which might be because it's considering them Canonical pages, even though they are not. What can I do to avoid this, and have Google index all of them?

EDIT: It could also be because it's not crawling the site to avoid overload. It says "Excluded. Not Crawled". Any way to increase the crawl rate? Would it go up automatically over time?

Thank you for the help.
