can't understand why google gets stuck on my site!

[scorpion]

We have a site for over 3 months and it is in google with the main url and sub_urls as follows:

main_url - title info - description
sub_page - NO TITLE - NO DESCRIPTION
sub_page2 - NO TITLE - NO DESCRIPTION

In fact no sub_page has any description (actually the url is the title of the listing).

ALso it only crawls 2-3 pages of the hundreds on the site. Why is google getting stuck on the top-level url and won't go deeper, instead selecting a few arbitrary links as sub_pages of the domain and not even crawling them? Is this a time issue, will take some more months or something wrong with the site? I don't use a robots file at all and linkage is clean and straightforward

Is any of the information in [webmasterworld.com...] useful to you?
