I just added a addon domain in Cpanel at hostgator & the
domain is also showing up at the end of my primary domain
like this

http://widgets.com/ (Primary)

http://widgets.com/newaddondomain (Addon sub folder)

This should create a duplicate content penalty with
Google and get me sanded boxed.

It shows up as a folder because google finds the folder
under your primary domain.

The only way to stop that site to show up as a folder would be put a robots.txt file in there but then that would not help because it will keep
the addon domain from being stored in google also.

How do I get the domain not show up under the primary as a sub folder.

It's normal for addon domains to be accessible that way. newaddondomain.widgets.com would also work. But if there's no link to the content in that manner on the net, the search engine won't know about it.

With cpanel 11 (ask for the x3 theme to be applied to your account) you can put the addon domain outside the public_html folder. The subdomain-type access remains though.

You can use 301 permanent redirects to have the addondomain accessible in a single manner. You should be able to find tutorials on that using Google.

Thanks I'll ask for the x3 theme. Are there any drawbacks to doing this, Like installing a wordpress blog etc.

There are no cPanel 11 features that would stop a script from working. It is definitely better to place an add-on domain outside the primary web root. Not all spiders/robots will follow your .txt file limitations.

Sorry ldcdc but I have to disagree with you. Simply having no links is not a good way of preventing search engines from indexing content. I say this from my own experience of having obscure directories indexed in google and also matt cutts talks about it here (hes a google engineer) and says the only way to guarantee no indexing is with .htaccess passwords.
