Content on New Domain or Sub Directory of Existing Domain?

[itrogers]

I have a client with a well aged, high DA site. They rank well for their wedding photography business in several cities.

They are launching a new service which is related to photography (photobooths and flipbooks) which they built and developed content on a new domain. The existing domain has 0 links with a DA of 1. The site is brand new..

Is there any drawback to moving the existing content on the new domain to a sub directory of the high authority domain? EX: http://domain.com/newcompany

The look, feel, and design of the new site / service is much different than the high DA site.

My thoughts are that this will give them an automatic step up, especially since they will be marketing this in several major cities.

Also, since the design will be different, if it is good to move to the subdir, should we put the new company name in the subdir folder or something keyword friendly like domain.com/photobooth as opposed to domain.com/newcompanyname.

Any thoughts would be greatly appreciated.

I'd only move it to a subdirectory if I could somehow link it (or integrate it to some level) from the main domain/site as well. If not, you could keep it on the new domain and link to that domain from the old one with a proper anchor to give it a boost, and since it's topic related it will indeed give it a boost.
