Working on a client project - a UGC community that has a DTC model as well as a white label model. Is it categorically better to have them all under the same domain? Trying to figure which is better:

XXX,XXX pages on one site

vs.

A smaller XXX,XXX pages on one site and XX,XXX pages on 10-20 other sites all pointing to the primary site.

The thinking on the second was that those domains would likely achieve high DA as well as the primary, and would passing their value to the primary.

Thoughts? Any other considerations we should be thinking about?
