Multipage domains vs single page

[Artificia]

Sorry if this has been posted before - I couldn't find it.

Is there an advantage to having only one page and product on a domain for the purposes of PPC affiliating?

Or is it just as effective (and obviously cheaper in terms of domain reg costs) to have a spread of different pitch pages each for a different product on one domain/site?

Having a domain would be preferred to having a yourproduct.domain.com or a www.domain.com/yourproduct

It's more convincing to the average user.
