Getting search engine results

I have several alias domains on a single godaddy account. I’ve installed WordPress in different subfolders and aliased a domain name to each. I’ve created blog names, tags etc. but I’m unable to get Google or Yahoo search engines to return references to my domains. They do return references to other WordPress blogs. Does this sound like an alias domain issue or am I setting up WordPress incorrectly.
A sample is capricaonline.com.
Thanks,
