SEO and Addon Domains

[karuna]

I just signed on with Hostgator, as so many people on this Forum seem to like it. So not familiar with the add-on domain thing.

My add-on domains/websites are completely different than the main domain and since the complete url that Hostgator uses is: www.addondomain.maindomain.com my question is does that affect SEO ranking for the add on domain?

I specifically chose my add on domains to be the exact word that would be search for, nothing else in the domain.

I know the user doesn't see the www.addondomain.maindomain.com. but sees www.addondomain.com

Does anyone know for sure if it affects search results?

I found this article on it, but am posting here, as I just wanted to hear some expert warriors opinions.

SEO Addon Domains / Subdomains

Thanks anyone!
