(Disclaimer - I am a n00b, I googled extensively both on- and off-site for this. Flame away 
I've read extensively about direct linking on Google. Then I realized I was sitting on my ass not doing a damn thing and I decided to get some action going.
I currently have 3 affiliate marketing type test/learning things underway. It was 4 but one was a failure and I pulled the plug already.
One of these three is a regular landing page + review + affiliate offer kind of site. I have adwords generating traffic for it - nothing spectacular yet. Still tweaking that one.
Another is an organic SEO type review site - I got a great domain name and I know a lot about the niche. So that's all fine and dandy.
The third attempt was going to be direct linking off of google adwords to offers on various networks (CB, etc). I picked one and got the affiliate link. I think took one of my many domains I have at GoDaddy and masked/redirected it to the offer.
My ads right now for this are sitting in "Pending Review" at Google. Not sure if they'll be approved.
Several of the things I said actually recommended doing this instead of how I have it above:
1.) Find an organic site not doing adwords ads
2.) Set that site as the display/destination URL
3.) Edit the individual keyword URL's to go to the affiliate link
I haven't done that yet - is that necessary to get direct linking to work at this point in time?
