I'm thinking of signing up with Spry and would like to start with a shared hosting package before upgrading to a dedicated server etc.
My first question is, do you use the Shared Domain Add On system for domain names?
I currently host some sites with another company which are mainly just parked for now so it's no big issue at the moment but it concerns me how Cpanel has this way you setup a domain name but it is not independent but is actually a sub domain.
For example I have a website www.righthosts.com that uses shared hosting and I have a few domain names added to this account.
Spry's shared hosting plans are powered by cPanel, and use Add-on domains in exactly the same way that you are describing. However, web spider results should not be affected unless you are linking site1.com/site2/ somewhere in your site1.com html.
I am unfamiliar with Google's beta sitemap service. I would think that Google would include a feature to creating an exlcusion list of "directories" that you do not want to be associated with the primary domain name. However, I am unable to quickly locate that functionality on their sitemap system.
Please let me know if you have any other questions.
