There are a lot of ways in order to get listed on Google. Here are some of those ways:
1. Search Engine Submissions
2. Build Links - back links helps your site get index. If you want your sub-pages get listed then deep linking helps.
3. Creating a sitemap - it helps your sub-pages get index.
4. Ping your site.
I think submit sitemaps to Google would help your sites in getting deeply indexed. For submitting, firstly you need to create an account with Google webmaster tool and then validate your sites using the code offered by Google. Lastly, submit your sitemap via webmaster tools. :)
