Evidence That Domain Ads Convert Better

Which advertising converts better - a search engine ad (Google AdWords for example shown to the right of organic search results) or the same ad displayed on a parked domain? 

In the domain industry, the latter is referred to as "the domain channel".  But in Google AdWords, you won't find any mention of domains at all.  Domain ads are included in Google's "content network" and Google provides  virtually zero information about it's content network and the "domain channel".

Consequently, there's a lot of debate and posturing surrounding this issue and little hard evidence, but here's some new fuel for the fire: DomainEditorial is reporting a case study showing the domain channel is twice as effective.
