Sub-Domain SEO Question

[LHofTHD]

So I did a little searching around the forum and couldn't quite find what I was looking for. I apologize if this has already been answered - I am definitely not an SEO expert.

I have a hosting account over at HostMonster where I have multiple domain names on one shared server. In order to achieve this they create sub-domains under my primary domain, however, they can be accessed like a regular domain.

E.G. addondomain.primarydomain.com = addondomain.com

My question is - how will search engines view this setup? Will they treat the "addondomain.com" as a separate domain or a subdomain? Also, will I be able to link between multiple add-on domains on my host and get credit for the backlinks?

Any advice on this type of hosting arrangement or any better alternative from an SEO perspective, would be greatly appreciated.
